HOW THE MACHINE WORKS

This machine can effectively scrub or sweep dirtyfloors. The 1--STEP Scrub button and 1--STEPSweep button make it possible to immediatelybegin scrubbing or sweeping.

The 1--STEP Sweep button operates all the drysweeping functions (without scrubbing). The1--STEP Scrub button operates all the scrubbingfunctions. (The machine also sweeps whilescrubbing).

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.

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.

OPERATION

17M20 331380 (6--06)

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 system, use the FaST system forthe 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 slowon inclines and slippery surfaces.

The maximum rated incline for scrubbing with themachine is 8_ or 14%. The maximum rated inclineduring transport of the machine is 10_ or 18%.
