HOW THE MACHINE WORKS

The following machine components work togetherto effectively clean dirty floors: solution tank,scrub brushes, squeegee, vacuum fan, andrecovery tank.

Water and detergent from the solution tank flow tothe floor through a solution valve. The brushesuse the detergent and water solution to scrub thefloor clean. As the machine propels forward, thesqueegee wipes the dirty solution from the floor.The suction created by the vacuum fan thendraws the dirty solution from the squeegee intothe recovery tank.

The steering wheel controls the direction ofmachine travel.The directional pedal controls thespeed and direction of the machine. The brakepedal slows and stops the machine.

The four available 700 mm (28 in) and 810 mm(32 in) scrub head types use disk or cylindricalbrushes.

NOTE: The amount and type of soilage play animportant role in determining the type of brushesto be used. For specific recommendations,contact your Tennant representative.

When finished scrubbing, clean the recovery tank.

OPERATION

7080 330820 (4--04)20

FaST SCRUBBING SYSTEM

Unlike conventional scrubbing, the FaST (FoamScrubbing Technology) system operates byinjecting the FaST PAK concentrate agent into thesystem with a small amount of water andcompressed air. This mixture creates a largevolume of expanded wet foam.

The expanded foam mixture is then dispersedonto the floor while the machine is scrubbing.When the squeegee picks up the mixture, thepatented foaming agent has collapsed and isrecovered into the recovery tank.

The FaST system can be used with all doublescrubbing and heavy duty scrubbing applications.

Using the FaST system can increase productivityby 30% by reducing your dump/fill cycle. It willalso reduce chemical usage and storage space.One FaST PAK of concentrated agent can scrubup to 1 million sq. ft.

NOTE: Do not enable the FaST system withconventional cleaning detergents in the solutiontank. Drain, rinse and refill the solution tank withclear cool water only before operating the FaSTsystem. Conventional cleaning detergents/restorers may cause failure to the FaST solutionsystem.

SCRUBBING AND BRUSH INFORMATION

Pick up oversized debris before cleaning. Pick uppieces of wire, string, twine, etc., which couldbecome wrapped around the scrub brushes.

Plan the scrubbing in advance. Try to arrangelong runs with minimum stopping and starting. Doan entire floor or section at one time.

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

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

When scrubbing dead end aisles, start at theclosed end of the aisle and scrub your way out.

Adjust the machine speed, scrub brush pressure,and solution flow as required when scrubbing.Use minimum scrub brush pressure and solutionflow required for the best results.

If you see poor scrubbing performance, stopscrubbing and refer to MACHINETROUBLESHOOTING.

For best results, use the correct brush type foryour cleaning application. The following arerecommended brush applications.

Non-scuff polypropylene scrub brush -- Thisbrush uses a softer, general purposepolypropylene bristle to lift lightly compactedsoilage without scuffing high-gloss coated floors.

Nylon scrub brush -- Recommended forscrubbing coated floors. Cleans without scuffing.

Super abrasive bristle scrub brush -- Nylonfiber impregnated with abrasive grit to removestains and soilage. Strong action on any surface,performing well on buildup, grease, or tire marks.

BATTERIES

The batteries are designed to hold their power forlong periods of time. The lifetime of the batteriesis limited to number of charges the batteriesreceive. To get the most life from the batteries,recharge them immediately when the batterydischarge indicator begins to blink.

After every 200 hours of use check for loosebattery connections and clean the surface of thebatteries, including terminals and cable clamps,using 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 clear battery post protectant 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.

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 ablove the batteryplates. If needed, add just enough distilled waterto cover the plates. Never add acid to thebatteries. Do not overfill. Always keep the batterycaps on, except when adding water or takinghydrometer readings.

MAINTENANCE

7080 330820 (12--02)48

Using a hydrometer, measure the specific gravityto determine the charge level and condition of thebatteries. If one or more of the battery cells testlower than the other battery cells (0.050 or more),the cell is damaged, shorted, or is near failure.Completely recharge the batteries, then retestthem.

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:
