HOW THE MACHINE WORKS

This machine can effectively scrub or sweep dirtyfloors. The 1−STEP button makes it possible toimmediately begin scrubbing or sweeping.

The 1−STEP button operates either the sweepingfunctions or scrubbing functions. (The machinealso sweeps while scrubbing).

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

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 alldouble scrubbing and heavy duty scrubbingapplications.

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 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 while double scrubbing.

OPERATION

35M20 Gas/LPG 9016000 (9−2016)

BRUSH INFORMATION

For best results, use the correct brush type for thecleaning application. Listed below are the brushesand the applications for which each is best suited.

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

PolyPro brush − Heavy duty polypropylenebristles provide a more aggressive cleaningperformance and can more easily lift compacteddirt, debris, and sand while offering excellentscrubbing performance.

Polypropylene brush − General purposepolypropylene bristles lift lightly compacted dirtwithout scuffing high-gloss coated floors.

Polyester brush − Softer general purposepolyester bristles lift light debris while sweepingand gently clean while scrubbing. Perfect forsensitive floor surfaces. Polyester does notabsorb water so it is preferred over Nylon in wetapplications.

Super AB brush − Nylon fiber impregnated withabrasive grit to remove stains and compacted dirt.Aggressive action on any surface. Performs wellon buildup, grease, or tire marks.

WHILE OPERATING THE MACHINE

Pick up oversized debris before scrubbing orsweeping. Pick up wire, string, twine, large piecesof wood, or any other debris that could becomewrapped around or tangled in the brushes.

Drive as straight a path as possible. Avoidbumping into posts or scraping the sides of themachine. Overlap the scrub/sweep paths byseveral centimeters (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 the machine is equippedwith the FaST or ec−H2O system, use the FaSTor ec−H2O system for the best scrubbing results.

Keep the machine moving to prevent damagingfloor finishes.

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.

Do not operate machine in areas where theambient temperature is above 43� C (110� F). Donot operate scrubbing functions in areas wherethe ambient temperature is below freezing 0� C(32� F).

FOR SAFETY: When using machine, do notscrub on ramp inclines that exceed 10% gradeor transport (GVWR) on ramp inclines thatexceed 14% grade.

ADJUSTING THE REAR SQUEEGEE BLADEDEFLECTION

Deflection is the amount of curl the overallsqueegee blade has when the machine movesforward. The best deflection is when thesqueegee wipes the floor dry with a minimalamount of deflection.

NOTE: Make sure the squeegee is level beforeadjusting the deflection. See LEVELING THEREAR SQUEEGEE.

1. Lower the squeegee and drive the machineforward a few meters (feet).


2. Look at the amount of deflection or “curl” ofthe squeegee blade. The correct amount ofdeflection is 12 mm (0.50 in) for scrubbingsmooth floors and 15 mm (0.62 in) for roughfloors.

12 mm(0.50 in)

3. To adjust the overall squeegee bladedeflection, turn the adjustment knobscounterclockwise to increase deflection orclockwise to decrease deflection.

4. Drive the machine forward again to recheckthe squeegee blade deflection afteradjustments are made.

5. Readjust the squeegee blade deflection ifnecessary.
