DEBRIS BODY DUMPING SAFETY AND HAZARD WARNINGS

NEVER leave body raised or partly raised while vehicle is unattended or while performingmaintenance or service under body unless body is propped to prevent accidental lowering.[Always disengage PTO when hoist is not in use or when moving vehicle.] The debris bodyMUST BE empty for service work.

• NEVER attempt to raise body when vehicle is on unlevel ground.NEVER GO UNDER A RAISED LOADED DEBRIS BODY.NEVER GO UNDER A RAISED BODY WITHOUT SECURELY PROPPING IT. BODYMUST BE EMPTY.

• Immediately report any damage or malfunction of the unit or components to your employer.• NEVER ride, or let any other person ride on ANY part of the vehicle other than in the cab.• Be certain that all individuals and obstructions are clear of the hoist and body before operating the

controls and be ready to stop operation at any time that a hazardous condition might occur.Use extreme caution when dumping contents of the debris body. Ensure all personnel areat least 20 feet away from truck. Select a dump site on level ground and clear of overheadobstructions that could be hit when raising the debris body. Serious injury or death to theoperator, bystanders could occur if precautions are not taken when dumping the contentsof the debris body.

• When positioning the truck at the dump station, choose an accessible location on level ground. Raising the debris body on unleveled ground increases the possibility of tipping.

• Make sure the area is clear of ground and overhead obstructions.• Never raise the debris body unless you can clearly see all overhead structures. Make sure you stay clear

of all utility lines.• Do not dump the debris body over a pit area where the ground may cave in or is unstable.• Use care when positioning the debris body to the dump station. Your vision, especially to the side and

rear of the debris body may be reduced by the size of the debris body. Use mirrors to aid vision. If you cannot see the dump site clearly, stop the truck and examine the area. If necessary, request assistance to guide you while backing the truck into position.

• Never drive with the debris body in the raised position. Traveling with the debris body in the raised position increases the chances of colliding with overhead obstructions. In addition, the center of gravity of the debris body is higher with a raised debris body, making the unit more prone to tipping over.

3.1 Start-Up Operations TestingAfter you perform a thorough inspection of the sweeper, always test the following components and adjust asneeded:

• Sweeping Head• Gutter Brooms• Magnet (if equipped)By locating any problems before traveling to the job site, you’ll save unnecessary travel time and will be able tomake repairs more easily with the proper tools close by.

Never run the Sweeper in a closed building or without adequate ventilation. The exhaustfumes can be hazardous to your health.

4. START-UP PROCEDURE AND OPERATIONMaterial in this section provides operating procedures for the following systems and devices:

• Console Controls• Auxiliary Engine• Dust Suppression System• Gutter Broom Operation• Hand Hose Operation• Magnet Operation• Spray Bar Operation

4.1 Console ControlsSweeping operations are controlled from the cab console control panel. Switches toggle differently dependingupon what sweeper devices they control.

Most sweeper devices requiring simple activation and deactivation are operated with 2-position ON and OFFswitches. These devices perform the following functions:

• Safety Features (Warning Lights and Safety Flashers)• Dust Suppression

Other devices require a 3-position switch. These switches are used for components which employ extensionand retraction or direction reversal. In many instances, one or both of the activation positions are momentaryON, meaning the switch will stay in that position only as long as it is manually held there. When released, theswitch will automatically return to the OFF position.

4.2 Sweeping Head OperationThe standard sweeping head is controlled by acontrol panel switch on the cab console. The switchis identified by the legend symbol shown.

Lowering and raising the pick-up head and hopperis controlled by a single switch and is a simple, two-step operation. The head will always lower beforethe hopper raises, and the hopper will always lowercompletely before the head rises.

4.3 Light/Heavy OperationThe bleeder door is used to direct all of the airflow down the pressure hose and into the head, or to divert aportion of the airflow to an exhaust location. Only in instances of light debris or leaves is the bleeder dooropened.

For sweeping of curb and gutter streets, the damper door should be in the ‘heavy’ or just slightly open position.This directs all or most of the airflow to the sweeping head, producing maximum blast in the sweeping head’sblast orifice.

When sweeping leaves or other light material, the damper door should be in the ‘light’ position, allowing someof the airflow through the blast orifice, reducing the air pressure exerted against the rear of the front curtain andpermits debris to pass beneath the front curtain more easily.

4.4 Gutter Broom OperationThe gutter brooms are activated by a control panelswitch located on the cab console. The switch isidentified by the corresponding legend symbolshown.

Use the following procedure to operate the gutterbroom under normal conditions in which streetgutters are accessible. The gutter brooms aredesigned to be full-floating. If you encounter anobstruction on the surface, the broom automaticallylifts to go over it. As broom bristles wear away, thebroom lowers to maintain contact with the surface.

Set the power setting to 90-100 and turn the broomon by pushing the ‘Broom On’ toggle. The broomwill extend and begin spinning clockwise. To stopthe broom, simply push and hold the ‘Broom In’toggle until the curb broom is fully retracted.

Section 4 - Service 4



4.0 Installation• Before beginning the actual installation process for the

Schwarze SuperVac Aero please read this entire chapter thoroughly.

• Prior to mounting your SuperVac Aero the tailgate must be removed from the truck onto which it is to be mounted.

Installing The Drag Arm Brackets

• Install the drag arm brackets to your truck frame• Use existing holes, and be careful not to rub or pinch any

wires or brake lines.

Do not weld or drill holes in the frame. This could weaken the structural strength of your vehicle’s frame and void the chassis warranty.

Installing The Wire Adapter• Install the wiring adapter, supplied, to your truck wiring, using

your choice of crimp or solder-less connectors.• Refer to the installation instruction supplied with the adapter

kit.

Adapter kits that install without splices are available for your specific truck chassis at your local auto parts store.

Installing The Sweeper

• Back your truck up under the SuperVac Aero unit.• Position the sweeper into the truck bed until the trailer

coupler is over the trailer ball on the truck.• Lower the trailer coupler onto the ball.• Latch and pin the trailer coupler.

The trailer coupler is what holds the unit in the truck bed.

• Lower the jack stands alternately by cranking the handles on all four corners.

• Continue lowering the jack stands until the sweeper sits down evenly on the truck bed.

• Make sure all six locking pins are engaged in the locking bosses and all jack stands become loose inside their jack holders.

Do not continue unless the jack stands are loose inside their jack holders.

• Remove the jack stands’ safety pins.• Remove jack stands from the sweeper.

IMPORTANT

NOTE

NOTE



Installing The Drag Arms

• Install drag arms to the drag arm plates• Adjust the drag arms using the adjustment holes• Make sure the sweeping head doesn’t touch the truck

bumper or chassis hitch receptacle (if equipped) when in the UP position

When hooked up correctly the head will be located directly under the head stops and the intake and exhaust tubes are aligned.

Adjusting The Head Stops• Adjust head stops to the correct height.• Make sure the sweeping head doesn’t touch the truck

bumper or chassis hitch receptacle (if equipped) and yet high enough for good ground clearance, when in the UP position

• The head stops should be positioned to allow only light contact with the sweeping head.

The sweeping head is raised and lowered with a hand cranked winch. Improper head stop height (too low) can cause lift cable, head or head stop damage.

Installing The Blower Tube Holster (Optional)• Attach the curb blower tube bracket to the LH side of truck

body in the stake pocket.

Most contractors find the curb blower to be an invaluable tool. That’s because use of it eliminates the need to use a backpack blower on all curbs in a parking lot. The high-speed air from the blower is sufficient to blow leaves, cigarette butts and most papers from curbs and planters. It will take time to master this technique but, once learned, you will appreciate the timesaving offered by the curb blower.

Removing The Sweeper

• Ensure that the SuperVac Aero hopper is empty of debris and the water tank has been drained

Ensure that the ground is clear, level and will support the weight of the empty sweeper.

• Place the four lifting jacks in position in each of the lifting tubes and insert safety pins.

• Disconnect trailer coupler and lighting wiring harness.• Unbolt drag arms from truck mounting brackets.

The mounting brackets can be left on the chassis for future use.

• Crank the 4 jacks evenly to raise the sweeper off the trucks bed by 2 inches.

Make sure all connections from sweeper to truck chassis are removed before moving the truck.

• Drive truck out from under sweeper.

Storing Your SweeperTo increased stability, when your sweeper is being stored for extended periods, the jacks should be lowered to lowest position while keeping the sweeper on level grounds.

For some systems and devices, such as daily examination of the ‘Y’ strainer, maintenance is regular andongoing. For others, we include a beginning statement to tell you when adjustment or replacement isnecessary. For example, when water flow is restricted at the right or left gutter broom, the dust suppressionsystem nozzles should be cleaned or replaced.

For many components, we also include a table of maintenance task and identify the section(s) of the manual toaccess for related procedures.

2.1 Maintenance LogsTo help you keep your Schwarze SuperVac Updraft in top operating condition, we have provided Sweeper andTruck Pre-Operation Inspection Sheets to be used before every sweeper operation. These forms can be foundin the beginning of the Operation Section of this Operator’s Manual. Please make copies and store them in afile to keep them accessible and clean.

You complete each form by:

• Recording the sweeper identification number• Recording the date• Checking off inspection/maintenance tasks• Signing your name

Additionally, each form has a Comments Section for:

• Providing detailed information on a listed item• Noting information about items not listed• Noting additional concerns• Specifying a needed replacement part• Recording the date a replacement part is ordered

The completed forms can be compiled in a notebook. Over time this will come to represent a comprehensiveinspection maintenance record for your sweeper.

WEEKLY MAINTENANCE (EVERY 40 HOURS)The following table tells you where to look in the manual to find procedures for specific occasional maintenancetasks:

3. CLEANINGDaily cleaning of the sweeper is a major factor in keeping it operating at its peak performance level. Dirt andgrime are always easier to remove before they have a chance to build up and bond to the sweeper surfaces.When the components on the sweeper are not cleaned regularly, debris collects and adheres rapidly. Thisdecreases the air flow, blocks the water nozzles and causes unnecessary wear. Component life will bemaximized by cleaning the sweeper as often as possible.

Spray wash the outside and underside of the sweeper and truck cab to remove rust causing road grime that isharmful to the painted surfaces. Clean out the truck cab and remove any objects not required during sweepingoperations. Also make sure that windows and mirrors are clean for maximum visibility.

At the end of each work shift, dump the hopper and wash it out. This will prevent corrosive road salts andorganic acids contained in debris from prematurely rusting the inside of the hopper raised an inch or two so thepressure against the fan and intake seals has been relieved and they may regain their shapes.

4. SWEEPER FLUID MAINTENANCE

4.1 Hydraulic SystemThe hydraulic oil level should be maintained such that it iskept at the full mark as measured with the hopper down.Check by using the sight level gauge, which is located onthe left side of the reservoir. Change the hydraulic oil andfilter after the first 500 hours of operation, then every 2000hours thereafter.

If the hydraulic fluid becomes cloudy, water hascontaminated the system and the hydraulic fluid needs to bechanged (after determining the source of the watercontamination and correcting it). If the sweeping unit isoperated in particularly dusty conditions, the hydraulic filterswill need to be changed more often.


Fan Housing Liner Check for wear and replace at first sight of holes.

Fan Housing Liner Bolts Check heads for wear and replace as needed.

Fan Check for wear and replace if blades are worn through

5. LUBRICATION SCHEDULERefer to the following table for correct sweeper lubrication.

6. FILTERSBecause of the dusty conditions under which a sweeper operates, filters are considered a priority maintenanceitem. Failure to properly follow filter change schedules may result in poor performance or costly componentreplacement.

6.1 Hydraulic Tank FiltersThe hydraulic tank has a single in-tank return filter, to remove foreign particles from the hydraulic oil that mightcause failure in the hydraulic system’s components.

6.2 Dust Suppression System FilterWater filter maintenance is an important part in keeping the sweeper’s water system functioning properly. Thestrainer should be emptied and its strainer screen flushed and cleaned daily. However, the frequency of filtercleaning varies and largely depends on the purity of the fill source’s water.

7. SEALSIt is important that the sweeper’s seals on the fan housing be kept in the best condition possible. These includethe seals on the suction hose inlet, around the hopper’s inspection door opening and on the rear door. Pickuppower is vacuum-dependent, so a tight seal can make a significant difference in pickup ability. Maintainresilience by keeping the seals well lubricated with a good grade of petroleum-based jelly or grease.

It is not necessary to lubricate the side inspection door seals, dump door and roof access door.

For longer seal life, when the sweeper is parked for an extended period of time, leave the hopper raisedseveral inches so the fan and intake seals can regain their shape.

Eventually the seals will become worn or non-resilient and must be replaced. When this occurs, a loss ofvacuum power results. To maintain sweeping efficiency, replace these seals periodically.

metal surface as clean as possible. Be sure it is free of all dirt, old glue, and seal material.2. Liberally apply a coat of weather-strip-type adhesive onto the new seal and body component. Allow the

adhesive to set up for several minutes (follow the adhesive manufacturer’s instructions) and then put thenew seal in place.

8. HOPPERThe hopper is one of the central components of the SuperVac Updraft sweeper. To ensure the longest possibleuseful lifetime, it is extremely important to clean it after each shift and to let it air dry with the hopper upwhenever possible.

9. DRIVE TRAINThe following sections contain procedures for replacement and servicing of the major components of the fan’sdrive train.

9.1 Drive BeltOn the rear of the auxiliary engine is the belt which drives the fan shaft. Check the belt tension periodically.This is accomplished by pressing down on the belt halfway between the two pulleys. With 30 lbs of pressure(the approximate equivalent of very firm pressure from on it from your thumb), the belt should deflect about 1/2”. An average belt, over the course of its life, will stretch slightly and the belt will need adjustment. This will beespecially true during the first 30-75 hours of operation.

Adjustment:The auxiliary engine, along with its engine skid, can be moved in the direction of the fan shaft (to loosen orremove the belt) or away from the fan shaft (to tighten the belt).

1. Remove the belt guard.2. Loosen (do not remove) the bolt which holds each of the four outer corners of the engine skid to the top of

the power module platform. 3. Locate the threaded rods known as jack screws. NOTE: Before adjusting the jackscrews, it is always a good idea to mark the present position of the engineskid, both at the front and rear, on the power module platform. This will allow you to determine how far theengine skid has been moved and whether the center line of the auxiliary engine is still parallel with the fanshaft.NOTE: Once the four tie-down bolts have been tightened, release the tension on the jackscrews.

4. Loosen the jackscrews' jam nuts. 5. By running the adjustment nuts in or out, the engine skid may be moved toward or away from the shaft.

Alternate adjusting the jackscrew nuts front to rear so that movement of the engine skid is even and theengine skid does not become misaligned. If you turn the front jackscrew three revolutions, then turn therear jackscrew three revolutions.

6. When proper belt tension is achieved, re-thread the loose adjustment nuts tightly against their powermodule platform tabs. (If you're adjusting the engine away from the fan shaft, these would be the inneradjustment nuts; toward the fan shaft, these would be the outer adjustment nuts.) Tighten any loose jamnuts back against their respective adjustment nuts.

8. Start the sweeper engine. Squealing or abnormal vibrations indicate low belt drive tension. Adjust asneeded.

9. Re-bolt the belt guard back into position.

9.2 Drive Belt ReplacementWith normal use, the drive belt will become worn. It is advisable to replace the drive belt when it shows signs ofwear, rather than waiting for it to break. This practice will help to ensure optimum sweeper performance andavoid downtime.

To replace the drive belt, reposition the sweeper engine. This can be accomplished by loosening the mountingbolts and jackscrews attached to the engine skid, as described in `DRIVE BELT.' Be sure to read the `DRIVEBELT' section before following the removal/replacement outline in this section.

Before installing a new drive belt, always inspect the belt pulleys for nicks, burrs or excessive wear. Replacethe pulleys if such irregularities are found.

Removal:1. Remove the sweeper engine's keys and/or disconnect the battery cable to prevent the sweeper engine

from being started accidentally. 2. Follow the procedures outlined in steps 1-4 in `DRIVE BELT.'3. Turn the jackscrew nuts so the engine skid is pushed toward the fan shaft. 4. As the engine skid moves toward the fan shaft, the drive belt will become loose enough to be slipped from

its pulleys.

Replacement:1. Inspect the pulley grooves for burrs and other irregularities that may cause abnormal belt wear. Correct as

required. 2. Slip the replacement belt into position. 3. Tighten the jackscrew nuts so the engine skid is pulled away from the fan shaft. 4. Continue to tighten until the belt has 1/2" deflection between the pulleys using 30 lbs. of pressure (roughly

the equivalent of pressing down on the belt with your thumb.) 5. Check the alignment of the pulleys, using a string or straight edge, from the face of one pulley to the face of

the other. This will allow you to determine whether the pulleys are in line with each other.NOTE: For slight misalignment, the pulleys may be repositioned on their respective shafts. If greateradjustment is needed than pulley repositioning can achieve, the entire engine / engine skid assembly must bemoved to obtained alignment. The slotted tie-down holes of the engine skid allow a limited amount of forward-back movement.6. Once proper pulley alignment is achieved, run the jam nuts back against their respective jackscrew nuts. 7. Tighten the four tie-down bolts at the corners of the engine skid.NOTE: Once the four tie-down bolts have been tightened, release the tension on the jackscrews.8. Start the sweeper engine. Squealing or abnormal vibrations indicate low belt drive tension. Adjust as

needed. 9. Re-bolt the belt guard back into position.

10. FAN HOUSINGThe fan housing directs the flow of air from the fan to the sweeping head. To provide the maximumperformance from the fan, the fan housing and drive components should be checked for wear regularly. Whensigns of wear occur on a component, replace it as soon as possible.

10.1 Fan Housing CheckWhen air is drawn from the hopper into the fan housing, a small amount of fine dust is also pulled into the fanchamber. This fine dust wears the fan blades, fan housing liner and the heads of the fan housing liner bolts.Over a period of time, the sandblasting effect of this dust will cause enough wear to these components thatthey must be replaced. Failure to replace them is dangerous and can be very costly, since a worn fan blade canbreak and damage the inside of the fan housing. Worn liner bolts may allow the fan housing liner to sag andcause damage to the fan as well as to its shaft and bearings. A worn liner permits the abrasive effect of theairstream to reach the walls of the fan housing, which is an expensive replacement item.

Inspection:1. Raise the hopper and insert the safety props into position.2. Remove the keys from the ignition and disconnect the battery cable to prevent the engine from accidentally

starting.3. Remove the back plate.4. Using a flashlight, inspect the fan blades, fan bushing, fan housing liner bolts and the fan housing liner for

wear.5. If no excess wear or abnormal wear is evident, replace the back plate, remove safety props and reconnect

the battery cables.

10.2 Fan Housing ReplacementIf a worn fan is causing reduced sweeping efficiency, it should be replaced promptly. The fan shaft bearingshave a life expectancy of roughly 2500 hours. When a fan replacement becomes necessary near the end of thebearing’s life expectancy, the bearings should likewise be replaced. Replacing both components will eliminatethe need to perform two, identical labor operations, and avoid downtime in close succession.

Exceptions to fan/bearing replacement:

• If you sweep in extremely sandy conditions, or do not use the sweeper’s water system, you may have toreplace fans more often than bearings.

• If the proper bearing lubrication procedures aren’t followed, you may have to replace bearings more oftenthan fans. However, in most cases, we recommend that the fan and bearings be replaced at the sametime.

Disassembly:1. Raise the hopper and place the safety stops over the dump cylinders.2. Remove the engine’s keys and disconnect the battery cables to prevent the engine from being accidentally

started.3. Remove the 3/8” lock nuts and washers from around the back cover plate and lift it off.4. Remove the 3/8” bolts and lock washers from the fan’s bushing.5. Reinsert two 3/8” bolts into the tapped holes of the bushing. Tighten these bolts evenly. This will push the

fan off the bushing.6. Use a gear puller to remove the bushing from the fan shaft.7. Remove the fan from the fan shaft and fan housing.8. While the fan is out, check the rubber liner inside the fan housing. If signs of excessive wear are apparent,

replace the liner. Failure to replace the relatively inexpensive liner could result in having to replace themore expensive fan housing later.

Replacement:1. Inspect the end of the fan shaft. Remove any burrs or rust from the shaft end with sandpaper.2. Place the fan on the fan shaft and push it back into the fan housing.3. Inspect the bushing. If the bushing is not cracked or otherwise damaged, the original bushing may be

reused.4. Apply an anti-seize agent to the tapered area of the bushing. 5. Slip the key into the bushing/fan shaft keyway.6. Position the fan bushing onto the fan shaft while aligning it with the shaft key as well as the fan. Spread the

bushing apart if necessary - remember, it will crack if it is overspread. 7. Drive the fan bushing onto the fan shaft until approximately 1/4” of the shaft extends from the face of the

bushing. (Use a rubber hammer or a wooden block and metal hammer to drive the bushing on.)8. Insert the three 3/8” bolts with lock washers through the untapped bushing holes and into the tapped holes

of the fan. Finger tighten the bolts. Do not tighten the bolts so as to secure the fan to the fan shaft.9. Apply strip caulk, or a similar sealing agent, to the face of the fan housing.10. Install the back cover plate (it may be necessary to move the fan and its bushing further into the fan

housing before the back cover plate can be mounted). Tighten the cover plate bolts.11. Move the fan back onto the fan shaft. Center the fan between the front and back of the fan housing.12. Position the fan on the fan shaft, taking into consideration that, as the fan is tightened onto its bushing, it

will travel roughly 1/4” toward the cover plate’s orifice. 13. While holding the fan in position on the fan shaft, tap the fan bushing along the fan shaft and into the fan’s

hub.14. When the fan bushing is snug inside the fan’s hub, insert the 3/8” bolts and tighten the fan onto the fan

bushing. As the bolts are tightened and the fan is drawn onto the bushing, the fan should move 1/4” towardthe cover plate.

15. Turn the fan to determine if it rubs the fan housing as it rotates. If the fan touches the fan housing, mark thebushing’s present position on the fan shaft (so it may later be used as a reference point). Remove the fanfrom its bushing and follow steps 12-16 to remount the fan further into the fan house. If the fan and fanhousing do not touch, proceed on to Step 16.

16. When the fan is properly mounted, swing the hopper safety prop into its stowed position and lower thehopper. Start the auxiliary engine, and again, listen for sounds of contact between the cover plate orificeand fan orifice. If none are audible, the unit is ready to sweep. If, however, sounds are detected, the hoppershould be raised and the fan readjusted.

10.3 Fan Housing Liner ReplacementTo prevent damage due to air-blast from the fan, a rubber liner is attached to the inside of the fan housing.Check the liner regularly for holes, tears or pitted areas, as well as for worn liner bolts. If the fan housing isexposed to direct wear because of a worn liner, the liner should be replaced. The rubber liner is relativelyinexpensive compared to replacing the fan housing.

Disassembly:1. Follow Steps 1-7 of ‘Disassembly’ in Section ‘Fan Replacement.’2. Unscrew the 3/8” nuts from around the outside of the fan housing and remove the elevator bolts holding

the rubber liner in place. Note the condition of the fan housing liner bolts. Worn bolts should be discardedand replacements used upon reinstallation.

3. Remove the worn liner in one piece if possible. Save it to use as a template to mark the new liner’s holepattern.

Replacement:1. Place the old liner on top of the replacement liner material and mark the length and hole pattern with spray

paint.2. Cut the liner material to length and use a hole punch or drill to make the holes.3. Notice that the replacement liner hole pattern is different at each end. Be sure you position the liner so that

its holes match the hole pattern of the fan housing.4. Start by installing the elevator bolts which hold the rubber liner to the top of the fan housing, and then

continue installing the remainder of the elevator bolts, working out and down from the top of the fanhousing.

5. Apply silicone to the outer edges of the liner and to the heads of the elevator bolts to prevent prematurewear and extend the life of the bolts and fan housing.

6. Check the fan blades for wear and replace the fan if needed. To replace fan, follow Steps 1-16 in‘Replacement’ of the preceding Section ‘Fan Housing Replacement’.

11. SWEEPING HEADThe sweeping head is dependent upon forced air and vacuum to achieve debris pickup. Without propermaintenance and replacement of parts due to normal wear, the sweeping head cannot provide the desiredsweeping results.

Forthe gutter broom hydraulic system maintenance, follow the procedures outlined for the gutter broom in Section‘Maintenance Schedules’ and in Section ‘Sweeper Fluid Maintenance.’

12.1 Gutter Broom Pattern CheckA broom pattern is the pattern of marks left on asweeping surface after the sweeper has passedover it. You should check this pattern to verify thefollowing conditions:

• That the broom is reaching the sweepingsurface

• That the left-broom pattern is a 9-to-1 o’clockcontact

Inspection:1. Move the sweeper to a flat asphalt or concrete sweeping surface and start the auxiliary engine.2. On the cab console control panel, toggle the gutter broom switch to ON.3. Allow the broom to run in contact with the sweeping surface for a minute or so.4. On the cab console control panel, toggle the gutter broom switch to RETRACT.5. Reverse the sweeper several feet to expose the surface just swept.6. Turn off the truck engine and set the parking brake.7. Get out of the cab and inspect the broom pattern (the worn area on the sweeping surface). If either pattern

is irregular, the corresponding gutter broom needs adjustment. Follow the procedures outlined in thissection to make corrections.

12.5 Gutter Broom Bristle ReplacementGutter broom bristles should be replaced when they are worn to approximately 6 inches in length. When gutterbroom bristles are allowed to wear shorter than 8 inches, the bristles gradually become too stiff and loose theirability to flick debris.

The gutter broom uses two poly wafer disks that are drawn into the broom head forming a cone shape. Do notover tighten, only a slight cone is required.

1. Place the gutter broom in the raised position.2. Remove the three bolts that hold the gutter broom bristle segment to the gutter broom disc, and set them

aside.3. Place new wafers under broom head with mounting plate under wafers. Mount with three bolts and tighten

evenly until a slight cone is formed.4. Verify that broom angle is set correctly, touching the ground at the outside 9:00 position and the forward

1:00 position.5. Start rear engine and rotate broom. Raise and lower broom to check operation.6. Check broom pattern and make adjustments as needed.

13. HYDRAULIC SYSTEM MAINTENANCEThe hydraulic system is important to the daily operation of the sweeper and should be treated as amaintenance priority. Check the hydraulic oil daily. The hydraulic oil level should be maintained at the 80%mark on the sight gauge located on the back of the reservoir. Check daily for leaks in hydraulic hoses andfittings. If a leak is detected, repair it as quickly as possible. Leaks allow hydraulic fluid out and are pointswhere dirt may enter the system.

13.1 Hydraulic Tank Fill-Up

Fill-Up:1. Locate the hydraulic tank on the left side of the sweeper.2. Examine the hydraulic fluid sight-level gauge located on the back of the tank. The hydraulic fluid within the

glass face of the gauge allows you to determine whether the tank needs filling.NOTE: The fluid level should register at or about the high mark.

3. If the tank needs filling, locate the fill opening on top of the hydraulic tank.4. Remove the cap.5. Use a funnel to fill the hydraulic reservoir to the desired level with one of the following:

• Shell Tellus 68 hydraulic fluid• Citgo 68 hydraulic fluid• An equivalent 22-weight (SAE) fluidNOTE: 30-weight (SAE) fluid is required for any system operating with an ambient fluid temperaturegreater than 100ºF.

6. Replace the cap.

13.2 Draining the Hydraulic Tank

Tank Draining:1. Locate the drain plug attached to the bottom of the hydraulic tank.2. Place a 5 gallon capacity container on the ground, positioning it below the drain.3. Remove the plug from the bottom of the hydraulic tank.4. Allow the fluid to drain.5. Reattach the plug to the bottom of the hydraulic tank.

13.3 Hydraulic Fluid Change

Hydraulic Fluid Should Be Changed When:• Maintenance records show that the new sweeper has completed its first 500 hours of operation• Thereafter, maintenance records should show that the sweeper has been operated 2,000 hours since its

last hydraulic fluid change. • If the hydraulic fluid becomes cloudy, water has contaminated the system. It should be changed and

flushed.NOTE: If the hydraulic oil contains water, be sure to determine the source of the water contamination beforechanging and flushing the hydraulic oil.

Fluid Change:1. Drain the hydraulic tank by following the procedures outlined in Section, ‘Draining the Hydraulic Tank.’2. Refill the hydraulic tank with one of the following;

• Shell Tellus 68 hydraulic fluid• Citgo 68 hydraulic fluid• An equivalent 20-weight (SAE) fluid.NOTE: 30-weight (SAE) fluid is required for any system operating with an ambient fluid temperaturegreater than 100ºF.

3. Choose one:• If you intend to reuse the hydraulic fluid just drained, filter it.• If you do not intend to reuse the hydraulic fluid just drained, transfer it to a closed container approved

by local, state and federal environmental agencies and deliver it to the appropriate disposal site.

13.4 Hydraulic FiltersNOTE: Replace or clean the suction filter after the first 500 hours of operation, then every 2000 hoursthereafter.

Replacement:1. Place a small tray or oil rag under filter before

removing.2. Remove filter by rotating canister counter

clockwise.3. Install new filter. Be sure to apply a small

amount of oil onto the filter gasket beforeinstallation.NOTE: Change the return filter after the first500 hours of operation, then every 2000 hoursthereafter.

4. Remove the lower housing of the PressureFilter.

5. Fill the hydraulic tank following the proceduresoutlined in ‘Hydraulic Tank Fill-up’.

6. Start the auxiliary engine and allow the fluid tore-circulate through the system.

7. If needed, refill the reservoir to the full mark ofthe site gauge.

13.5 Directional Valve OverrideYour unit is equipped with manual overrides, whichcan be used at any time if you blow a fuse or haveany other electrical problem. The overrides controlthe gutter broom only.

The gutter broom override is located at the center ofeach coil of the gutter broom valve. To manuallyoverride the valve, use a small screw driver orround pin to depress to center pin to shift valve.One side of the valve lowers and the other side lifts.

14. DUST SUPPRESSION SYSTEM MAINTENANCEThe standard water system consists of a gravity-feed water line to the sweeping head and a flowjet water pumpfor the hopper, gutter broom spray nozzle dust suppression. The water line for the head needs little in the wayof maintenance except the occasional check beneath the sweeping head to be sure that its outlet has notbecome clogged. However, the water strainer should be cleaned daily and the water nozzles checked foroperation and cleaned as needed. When freezing temperatures are expected, the water reservoir should bedrained or an environmentally safe anti-freeze added to the water per the anti-freeze manufacturer’sinstructions.

14.1 Water Filter CleaningThe plastic strainer, located beneath the left water reservoir, is positioned in-line between the water reservoirand the water pump. Its purpose is to remove particles from the water that might cause failure of the spray tipsof the dust suppression system. The cap spins off for easy daily flushing of these trapped particles. Generallyspeaking, once a week, the reservoir should be drained, the bottom of the strainer unscrewed, and thecylindrical screen within the strainer removed and cleaned. Of course, the frequency of the need to clean thisscreen will vary depending upon the purity of the water from the fill source.

Cleaning:1. Drain the reservoir.2. Unscrew the bottom of the strainer. Remove

and clean its screen.3. Reassemble the strainer.

14.2 Water Nozzle Cleaning/ReplacementA dust suppression system nozzle needs cleaning when it is clogged and water flow is restricted.

Due to dusty conditions encountered during sweeping operations, dirt and debris particles entering the dustsuppression system are sometimes small enough to pass through the ‘Y’ strainer. These particles can build upwithin a nozzle’s openings, restricting water flow. When this occurs, the nozzle must be cleaned or replaced.

Cleaning/Replacement:1. Unscrew the nozzle retainer cap and set it

aside.2. Remove the spray tip and strainer.3. Wash the strainer and examine it.4. Choose one:

• If washing the strainer has removed allparticles or debris, set aside the (nowclean) strainer.

• If the strainer can no longer be thoroughlycleaned, it needs to be replaced.

5. Wash the spray tip and examine it.6. Choose one:

• If the spray-tip opening is clogged, insert asmall-gauge wire into the spray-tip openingto clear any debris lodged inside.

• If the spray tip is damaged, it needs to bereplaced.

7. Reassemble the nozzle, replacing anydamaged parts as necessary.

8. Unscrew the bottom of the ‘Y’ strainer housingto drain the water reservoir(s).

9. After the water flow stops, reassemble the ‘Y’strainer housing.

14.3 Dust Suppression System WinterizingYou must winterize whether or not you will use your sweeper during freezing temperatures. In either case,winterizing your Schwarze Updraft will help keep it in top operating condition, extending its length ofservice.

Failure to winterize the dust suppression system could result in damage to your sweeper.

Choose one:

• If your sweeper’s dust suppression system will be operated during freezing temperatures, complete thefirst procedure.

• If your sweeper’s dust suppression system will NOT be operated for several weeks when freezingtemperatures are expected, complete the second procedure.

System Winterization:If antifreeze is to be used to protect the sweeper’s water system, it is imperative that it bean environmentally safe antifreeze. Common non-biodegradable antifreeze should NEVERbe used in the water system.

1. Following the antifreeze manufacturer’s instructions, add environmentally safe antifreeze to the water bypouring it through the air-gap opening in the top of the reservoir.

2. Turn Auxiliary Engine key switch to the ‘ON’ position. (Starting the engine is not required.)3. Turn ON the Water pump.4. Turn ON all cab console control panel switches controlling water manifold solenoids.
