HOW THE MACHINE WORKS

The 1−STEP button makes it possible toimmediately begin scrubbing by operating all thescrubbing functions.

When in the conventional Scrub mode, a waterand detergent mixture is used to scrub the floor.

When in the optional ES (Extended Scrub) mode,the dirty solution in the recovery tank is filteredthrough the ES system and returned to thesolution tank for reuse. Detergent is then injectedinto the returned solution to revitalize the cleaningcapability of the solution.

When in the optional FaST (Foam scrubbing)mode, the FaST scrubbing system mixes theFaST−PAK concentrate with a small amount ofwater, creating a large volume of expanded wetfoam. The FaST system can be used with allscrubbing applications.

When in the optional ec−H2O (electricallyconverted water) mode, normal water passesthrough a module where it is oxygenated andcharged with an electric current. The electricallyconverted water changes into a blended acidicand alkaline solution forming a neutral pH cleaner.The converted water attacks the dirt, breaks it intosmaller particles, and pulls it off the floor surfaceallowing the machine to easily scrub away thesuspended soil. The converted water then returnsto normal water in the recovery tank. The ec−H2Osystem can be used with all double scrubbing andheavy duty scrubbing applications.

BRUSH AND PAD INFORMATION

For best results, use the appropriate brush or padfor the cleaning application. Listed below arebrushes and pads and the applications for whicheach is best suited.

NOTE: The amount and type of soilage play animportant role in determining the type of brush orpad to use. Contact a Tennant representative forspecific recommendations.

Nylon brush (Disk)* − Softer nylon bristles arerecommended for scrubbing coated floors. Cleanswithout scuffing.

Polyester brush (Cylindrical) − Softer generalpurpose polyester bristles gently clean whilescrubbing. Perfect for sensitive floor surfaces.Polyester does not absorb water so it is preferredover Nylon in wet applications.

PolyPro brush (Cylindrical) − Heavy dutypolypropylene bristles provide a more aggressivecleaning performance and can more easily liftcompacted dirt, debris, and sand while offeringexcellent scrubbing performance.

Polypropylene brush (Cylindrical and Disk)* −General purpose polypropylene bristles lift lightlycompacted dirt without scuffing high-gloss coatedfloors.

Super AB brush (Cylindrical and Disk)* −Nylon fiber with an abrasive grit to remove stainsand compacted dirt. Aggressive action on anysurface. Performs well on buildup, grease, or tiremarks.

* This brush is also available for the side brush.

Stripping pad (Brown)− Quickly and easily cutsthrough old finish to prepare the floor forrecoating.

Scrubbing pad (Blue) − Removes dirt, spills, andscuffs. Leaves a clean surface ready forrecoating.

Buffing pad (Red) − Quickly cleans and removesscuff marks while polishing the floor to a highgloss.

Polishing pad (White) − Maintains a high gloss.Use for buffing very soft finishes and lower trafficareas, and polishing soft waxes on wood floors.

OPERATION

15T16 9008142 (1−11)

High productivity pad (Black) − Aggressivelystrips floor finishes/sealers. Use for veryheavy−duty scrubbing. This pad can only be usedwith the grip pad driver, not the tufted pad driver.

Surface preparation pad (Maroon) −Aggressively strips floors without use ofchemicals.

Grip pad driver − The grip−face backing allowspads to be fully used and holds pads in placewithout penetrating the pad. The spring−activatedcentering device works with all Tennant pads andallows for fast, easy pad replacement.

Tufted pad driver − Standard pad driver hasshort bristles, or “tufts,” on the back to hold thepad in place. This driver works with all Tennantpads except the black high productivity pad.

WHILE OPERATING THE MACHINE

Pick up oversized debris before scrubbing. Pickup wire, string, twine, large pieces of wood, or anyother debris that could become wrapped aroundor tangled in the brushes.

Drive in a straight a path as possible. Avoidbumping into posts or scraping the sides of themachine. Overlap the scrub paths by severalcentimeters (a few inches).

Avoid turning the steering wheel too sharply whenthe machine is in motion. The machine is veryresponsive to the movement of the steering wheel.Avoid sudden turns, except in emergencies.

Adjust the machine speed, brush pressure, andsolution flow as required when scrubbing. Use thelowest brush pressure and solution flow settingsfor best performance.

If poor cleaning performance is observed, stopcleaning and refer to MACHINETROUBLESHOOTING in this manual.

Perform the Daily Maintenance Procedures aftereach use (see MACHINE MAINTENANCE in thismanual).

Drive the machine slowly on inclines. Use thebrake pedal to control machine speed ondescending inclines. Scrub with the machine upinclines rather than down inclines.

FOR SAFETY: When using machine, go slowlyon inclines and slippery surfaces.

The maximum rated incline for scrubbing with themachine is 4� or 7%. The maximum rated inclineduring transport of the machine is 8� or 14%.

BATTERIES

The batteries are designed to hold their power forlong periods of time between charges. Thelifetime of the batteries is limited by the number ofcharges the batteries receive. To get the most lifefrom the batteries, charge them when the lastbattery discharge indicator segment flashes (20%charge left). Use an automatic charger with theproper rating for the batteries.

Check the electrolyte level in each battery cellbefore and after charging, and after every 50hours of operation. Do not charge the batteriesunless the fluid is slightly above the battery plates.If needed, add just enough distilled water to coverthe plates. Never add acid to the batteries. Do notoverfill. Always keep the battery caps on, exceptwhen adding water or taking hydrometer readings.

After every 200 hours of use check for loosebattery connections and clean the surface of thebatteries, including terminals and cable clamps,with a strong solution of baking soda and water.Brush the solution sparingly over the battery tops.Do not allow any baking soda solution to enter thebatteries. Use a wire brush to clean the terminalposts and the cable connectors. Wipe off allcleaning solution residue. After cleaning, apply acoating of battery terminal protector to theterminals and the cable connectors. Keep the topsof the batteries clean and dry.

Objects made of metal can potentially short circuitthe batteries. Keep all metallic objects off thebatteries. Replace any worn or damaged wires.

Measuring the specific gravity, using ahydrometer, is a way to determine the chargelevel and condition of the batteries. If one or moreof the battery cells test lower than the otherbattery cells (0.050 or more), the cell is damaged,shorted, or is about to fail.

04380

NOTE: Do not take readings immediately afteradding distilled water. If the water and acid are notthoroughly mixed, the readings may not beaccurate. Check the hydrometer readings againstthe following chart to determine the remainingbattery charge level:

Circuit breakers 1 through 10 are located in thefront of the battery compartment.

Circuit breakers 11 through 19 are located on theelectrical panel.

Circuit breaker 20 is located inside the optionallight assembly mounted on top of the recoverytank.

If the overload that caused the circuit breaker totrip is still present, the circuit breaker will continueto stop current flow until the problem is corrected.

The chart below shows the circuit breakers andthe electrical components they protect.
