Operating Instructions
The unit must be properly operated and properlymaintained to help avoid accidents that coulddamage the unit and injure the operator orbystanders. This section of the OperatingInstructions manual review basic operations anduse of controls. These instructions should bereviewed with all employees before they areallowed to work with the machine. Keep theseinstructions near the machine for easy reference.
Bead Loosening and Demounting
This machine mayoperate differentlyfrom machines you
have previously operated. Practice with aregular steel wheel and tire combination tofamiliarize yourself with the machine's operationand function.
Remember to remove all weights from bothsides of the wheel. Weights left on back side ofwheel may cause the wheel to be clampedunlevel. This may result in the combinationmount/demount head contacting the rim causingscratches. On alloy wheels, always rotate thewheel one turn after setting the head to insureproper wheel chucking.
NOTE: Always review nicks and scratches withowners of expensive wheel and tirecombinations prior to servicing.
IMPORTANT: Review the performance wheelsection of this manual prior to servicingperformance tire/wheel combinations.
1. Deflate tire completely by removing the valvecore from the valve stem (Figure 1).
Figure 1 - Remove Valve Core to Deflate Tire
NOTE: Loosening the beads on a fullyinflated tire is unsafe and causes excessmovement and friction against the bumperpads and excessive wear on pivots. Deflatethe tire completely to prolong the life of yourmachine.
ATV NOTE: It may be necessary on ATVwheels to leave 5-10 PSI in some of thesewheels to facilitate bead loosening.
NOTE: Always loosen the bead on thenarrow side of the wheel's drop center first(motocycle wheels may not have a narrow orlong side, and some ATV wheels may may
bolt together). See Figure 4 for moreinformation on the drop center.
REMEMBER: The clamps on the table topmay extend beyond the table top itself. Toavoid damaging the clamps, move them totheir full inward position before positioning atire for bead loosening.
NOTE: Use extra care in positioning the beadloosener shoe on larger wheels/tires, and onalloy wheels. Make sure the shoe rests nextto but not on the rim, and not on the tiresidewall. The riser underneath the beadloosener will help properly position ATVwheels.
2. Pull the bead loosener shoe away from themachine and roll wheel into position. Thevalve stem should be in the 3 o'clockposition. Position the bead loosener shoeagainst the tire next to, but not on, the rim.Depress the bead loosener foot pedal toactuate the shoe and loosen the bead. It maybe necessary to loosen the bead in multiplelocations around the tire (Figure 2).
Figure 2 - Position Tire and Bead Loosener Shoe
3. Turn wheel around and repeat looseningprocedure on the other side of the wheel.This should be the long side of the dropcenter.
TIP: It will be easier to clamp the wheel to thetable top if the lower bead is loosened last.
4. Apply tire manufacturer's approved rubberlubricant liberally to entire circumference ofboth tire beads after loosening.

5. Determine the mounting side of the wheel.The mounting side is the narrow side of thedrop center. (Tire removed in Figure 4 forclarity.)
Figure 4 - Determining Mounting Side of Wheel
6. Place tire/wheel assembly on table top withmounting side up (Figure 5). Use the clampcontrol pedal to move the clamps inwards(push pedal down) or outwards (toggle pedalup). Clamp motorcycle and ATV wheels fromthe outside (clamps push inwards against theoutside rim edge). Place rim flange into rearclamp and slowly move the other clampsinward until they contact the rim. Observeclosely to prevent tire/wheel damage.
Figure 5 - Place Tire/Wheel Assembly on Table Top
7. Move the swing arm into position. Pull thelocking handle forward to release the slide.Push down on the top of the vertical slide tomove the demount head into contact withthe rim edge. Push the locking handle back tolock the slide into place. As the slide islocked, the mount/demount head will moveupward approximately 1/8 inch from the rimedge.
Figure 6 - PositionMount/Demount Tool
8. The mount/demount head roller should be incontact with the rim edge. Turn the swingarm adjusting knob to move the head awayfrom the rim 1/8 to 1/4 inch.
Figure 7 - Adjust Swing Arm to Position Head Roller
9. Check head positioning. Mount/demounthead should be positioned with 1/8 to 3/16"clearance between the top of the rim edgeand the bottom of the head, and 1/8 to 1/4inch clearance between the rim edge and thehead. This clearance will be maintained aslong as the locking handle and adjustmentknob are not changed. The operator mayswing the arm out of the way and back intoplace again without needing to reposition thehead (when changing a set of the samewheels).
Figure 8 - Proper Mount/Demount Head Position
IMPORTANT: The vertical tool clearance maychange with machine use and should beinspected often. Failure to maintain theproper clearance may result in damage to thewheel rim and/or tire.
10. Insert the smooth curved end of the beadlifting tool over the forward end of thedemount head and below the top bead of thetire. Use your free hand to press down on thetire opposite the head to help with toolinsertion (Figure 9).

12. Depress the table top pedal to rotate thewheel clockwise. The demount head willguide the upper bead up and over the edgeof the wheel.
NOTE: Push down on the tire across from thedemount head during table top rotation toutilize the drop center area of the wheel. Thisreduces the tensional force on the beadduring demount.
13. Lift and hold the tire at an angle so that thelower bead is resting in the drop centerdirectly across from the demount head, andis loose below the demount head (Figure 11).Insert the smooth curved end of the beadlifting tool down over the forward end of themount/demount tool and below the lowerbead. Lift the bead up and over the knob onthe demount head (Figure 11).
Figure 11 - Demounting Lower Bead
14. Depress the table top pedal to rotate thewheel. The demount head will guide thebead up and over the edge of the wheel.Continue rotation until lower bead isdemounted.
NOTE: With tube-type tires, demount the upperbead and remove the tube before demountingthe lower bead.
NOTE: Table top rotation can be stopped at anytime by removing your foot from the pedal.
NOTE: Normal table top rotation for demountingis clockwise. Depress the table top pedal torotate this direction. To rotate the table topcounterclockwise, lift the pedal up with your toe.
At times during the
mounting and
d e m o u n t i n g
procedure, the bead lifting tool may encounter
resistance or come under load. Keep one hand
firmly on the tool to avoid possible tool
disconnect. Use the reversing feature to back
out or jam ups.
After successfully completing thedemount process, proceed to Mounting(page 6).

Mounting
This information must be read and followedcarefully to prevent accidents and injuries duringmounting.
Check tire and wheelcarefully beforemounting. Make sure
the tire bead diameter and wheel diametermatch exactly. Consult the RubberManufacturer's Association for approved rimwidths for tire sizes. Mis-matched tires andwheels explode.
Never Mount a tireand wheel handed toyou by anyone
without checking both tire and wheel fordamage and compatibility. Be extra cautious ofpersons without knowledge of tire service. Keepby-standers out of service area.
Never mount adamaged tire. Nevermount a tire on a
rusty or damaged wheel. Damaged tires and/orwheels may explode.
If you damage thetire bead duringmounting, STOP!,
remove the tire and mark it as damaged. Do notmount a damaged tire.
1. Inspect the wheel closely for damage. Cleanthe wheel and remove any light corrosion orrubber residue (Figure 12). Do not attempt toservice heavily corroded wheels.
Figure 12 - Inspect and Clean the Wheel
2. Inspect tire for damage, paying closeattention to the beads. Verify size matchbetween tire and wheel (Figure 12).
4. Place tire over wheel and move swing arminto position. Position the tire so that thelower bead is above the rear extension of themount/demount head and below the frontknob (Figure 14).
Figure 14 - Position Tire Against Mount/Demount Head
5. Depress table top pedal and rotate the wheelto mount the lower bead. Use the dropcenter of the wheel to reduce the tensionalforce on the bead by pressing down on thetire directly across from the mounthead.Rotate table top until lower bead is fullymounted.
6. For top bead, rotate the table top until thevalve stem is directly across from the mounthead. Lift the upper bead up and over therear of the mount head. With your left handpress down on the tire between the mounthead and the valve stem to hold the tire inthe drop center. Depress the table top pedaland rotate the tire until the bead is mounted.Continue to press down on the tire duringthe remaining mounting process.
Do not force the tireonto the rim. Beaddamage could result
making the tire unsafe and/or creating the riskof injury.
NOTE: If table top rotation stalls, reverse thetable top momentarily until the tire bead is againloose on the wheel. Reposition the mount head,make sure the bead is correctly positioned in thedrop center of the wheel, then attempt mountingagain.
NOTE: For low profile or stiff sidewall tires, itmay be advantageous to use the bead lifting toolto initially hold the upper bead down in the dropcenter, or use drop center tools as shown inFigure 30, page 11.
NOTE: For tube type tires, mount the lower beadfirst, move swing arm out, install the tube, andthen mount the upper bead.
When you have completed themounting process, proceed to Inflation,page 7.

Inflation
On the RC100, tire inflation is performed in twosteps: Bead Seat and Inflation. These steps areexplained in detail on page 13. Read theexplanation of each step and understand themthoroughly before proceeding.
Check for properinflation gaugeoperation. Accurate
pressure readings are important to safe tireinflation. Refer to the Operating Maintenancesection of this manual for instructions.
If the rim has beenclamped from theoutside for tire
mounting, release the clamps, lift the tire, andmove the clamps to the center of the table top.
Tire failure underpressure ishazardous. This tire
changer is not intended to be a safety device tocontain exploding tires, tubes, wheels, or beadsealing equipment. Inspect tire and wheelcarefully for match, wear, or defects beforemounting. Always use approved tire beadlubricant during mounting and inflation.
The inflation pedal, located at the rear of the leftside of the machine, controls the flow of airthrough the inflation hose.
NOTE: The clip-on chuck on the end of the hoseshould always be an open style with all parts inproper working order.
Position 1 - At Rest – With the inflation hoseattached to the tire valve and the pedal in thisposition, the air gauge will register the airpressure in the tire. Whenever your foot isremoved from the pedal, it will return to thisposition.
Position 2 - Tire Inflation – This is the firstactivated position. With the inflation hoseattached to the tire valve and the pedal in thisposition, line pressure is allowed to flow throughthe valve and into the tire for inflation. Tirepressure is not indicated on the gauge in thisposition.
Bead SeatingOperator shouldkeep hands, arms,and entire body
away from the tire during the remaining beadseat and inflation procedures. Do not stand overtire, as personal injury could result.
NEVER increase airpressure to exceed40 PSI when
attempting Bead Seat. If operator is unable toobtain Bead Seat, something is wrong. Deflatetire completely, inspect both the tire and wheel,correct any problems found, relubricate both tirebeads, and reattempt Bead Seal and Bead Seatprocedures. Follow all safety instructions in thismanual and on machine.
1. Once tire pressure is indicated on the airgauge (inflation pedal in position 1; footremoved from pedal), continue to inject airinto the tire in short intervals. Check thepressure frequently.
Stand back during bead seat. Keep hands,arms, and entire body away from tire duringthis procedure.
Tire beads should move outward and "pop"into their bead seat position as pressureinside the tire increases. If this does nothappen, a problem exists. Investigatecarefully.
Check tire pressurefrequently. Neverexceed 40 PSI while
seating beads. Once seated, never exceed tiremanufacturer's recommended air pressure. Tirescan explode, especially if they are inflatedbeyond their limits. At all pressure levels wheninflating through the valve stem, keep hands,arms, and entire body away from inflating tire.An exploding tire, wheel, or bead sealingequipment may propel upward and outwardwith sufficient force to cause serious injury ordeath to operator or bystander.

Only tire technicianswith experience andtraining on custom
wheels should attempt to service expensivecustom alloy or aluminum wheels and high-performance low-profile tires.
Pre-Operation Notes:• Ensure all weights have been removed.
• Assistance will be required on wide wheels.
• Clamp wheel from the outside.
• Use ample lubricant for mount anddemounting
• Always review wheel nicks and/or scratcheswith the owner before servicing.
Aluminum and Custom WheelsFollow instructions provided for standard steelwheels, except:
A. After loosening and lubricating both beads,rotate the table top until the clamps are inthe 12, 3, 6, and 9 o'clock positions.
Figure 16 - Rotate Table Top to 12 O'clock
B. Clamp wheel from the outside. Position rimedge into clamp at 12 o'clock position. Lowerthe wheel and depress the clamp controlpedal. Slowly move the clamps inward untilthey securely contact the outside edge of therim.
TIP: This is usually accomplished bycrouching down in front of the tire changer,holding the wheel with the right hand, andoperating the clamp control pedal with theleft hand. This allows the operator to watchthe clamps as they move to ensure proper,damage-free clamping.
Performance Tires and Wheels • DemountingFollow these instructions for performance typetires and wheels, including run-flat tires and theirassociated wheels, and asymmetrical humpwheels.
1. Remove the valve core and completelydeflate the tire.
2. Pull the bead loosener shoe away from themachine and roll the tire into position againstthe bumper pad. Position the tire with thevalve stem in the 3 o'clock position (in directline with the bead loosener shoe). Alwaysloosen the bead on the narrow/mountingside of the wheel first (Figures 4 and 17).
Figure 17 - Position Tire for Bead Loosening
NOTE: Wheels with an asymmetrical humphave a larger "ledge" type hump around thewheel except at the valve hole making themmore difficult to mount/demount (Figure 18).
Figure 18 - Asymmetrical Hump Wheel
NOTE: Some wheels have a low pressuresensor/transmitter strapped to the wheel. This isespecially true on run-flat tire/wheel systems.The sensor is positioned directly opposite fromthe valve stem. To avoid damaging the sensor,always loosen the top bead at the valve stemfirst, then loosen the bottom bead at the valvestem, and then continue to loosen the remainingcircumference of the beads as necessary (Figure19).

Stages of Inflation
Review these descriptions and diagramscarefully. Refer to them as necessary duringbead sealing, bead seating, and inflation to verifythat you are proceeding properly and safely.
Bead Sealing (machines equipped with Air Blast)
A 140 PSI air blast from the table top jets createsan air curtain to aid in bead sealing. Neverexceed 10 PSI in the tire during bead sealing.The tire will contain about 1/2 to 2 PSI whenbead seal is obtained.
Bead Seating
Bead seating usually occurs on the long taperedside of the wheel first and the shorter side last.Bead seating will usually require at least 7 PSI inthe tire. 40 PSI is the maximum safe pressure atthis stage regardless of operating pressure.
Most European import cars and manyaftermarket alloy wheels are very tight and canbe difficult to bead seat. Also note thatasymmetrical hump and run-flat tires are
After the beads are seated, the tire is inflated. Donot inflate the tire above the manufacturer'srecommended pressure as stamped on the tiresidewall. The typical inflation pressure forautomobile tires is between 24 and 45 PSI. Lighttruck inflation pressure typically covers a widerrange.
MIS-MATCHED TIRES AND WHEELS
Never attempt to mount and inflate mis-matchedtires and wheels.

Workspace Requirements
Air SourceThe RC100 requires a 5 CFM air source at 150PSI. The safe operating pressure range isbetween 110 PSI and 175 PSI at the machine. Formotorcycle and ATV tires, this pressure shouldbe regulated to 90-100 PSI at the machine.
The unit is furnished with a 1/4" pipe thread malefitting for easy connection. This connection islocated on the right side of the rear of themachine. A 1/4" ID hose (or pipe) for connectionto the machine is satisfactory. Sufficient airpressure assures good performance.
Floor MountingThe machine may be mounted to the floor ifdesired. Use suitable anchors in the mountingholes at each corner of the machine.
READ…Mounting and inflating thewrong size tire can getyou hurt. Read the size onthe tire and make sure itmatches the rim. Be espe-cially careful about puttinga smaller tire on a largerrim, such as a 16-inch tireon a 16.5-inch rim.
Inflation of a mismatchedtire and rim can cause anexplosion.
INSPECT…Before you put any tire ona rim, inspect the rim forrust, tough spots, bentedges, or cracks thatcould prevent the tire fromseating right. If you spotany of these problems,don’t mount the tire untilthe rim has been checkedby your shop foreman.
Inspect the tire for beaddamage.
MOUNT…Once you’ve made sure the tire is OKand the right size and the rim is OK,mount the tire safely. NEVER, everlean over the tire when you’re inflatingit. If a tire does explode, it will gostraight up. You don’t want to be overthe tire if that happens. Also, neverover-inflate the tire, even if the beaddoesn’t seat. Never inflate over 40PSI. If the tire hasn’t seated, some-thing is wrong. Deflate the tire andcheck it and the rim again. If it doesn’twork the second time, try another tire.
