OPERATION

HOW THE MACHINE WORKS

This machine can effectively scrub or sweep dirty floors. The 1−STEP Scrub button and 1−STEP Sweep button make it possible to immediately begin scrubbing or sweeping.

The 1−STEP Sweep button operates all the dry sweeping functions (without scrubbing). The 1−STEP Scrub button operates all the scrubbing functions. (The machine also sweeps while scrubbing).

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

When in the optional FaST (Foam scrubbing) mode, the FaST scrubbing system mixes the FaST−PAK concentrate with a small amount of water, creating a large volume of expanded wet foam. The FaST system can be used with all double scrubbing and heavy duty scrubbing applications.

When in the optional ES (Extended Scrub) mode, the dirty solution in the recovery tank is filtered through the ES system and returned to the solution tank for reuse. Detergent is then injected into the returned solution to revitalize the cleaning capability of the solution.

When in the optional ec−H2O (electrically converted water) mode, normal water passes through a module where it is oxygenated and charged with an electric current. The electrically converted water changes into a blended acidic and alkaline solution forming a neutral pH cleaner. The converted water attacks the dirt, breaks it into smaller particles, and pulls it off the floor surface allowing the machine to easily scrub away the suspended soil. The converted water then returns to normal water in the recovery tank. The ec−H2O system can be used while double scrubbing.

OPERATION

BRUSH INFORMATION

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

NOTE: The amount and type of soilage play an important role in determining the type of brushes to use. Contact a Tennant representative for specific recommendations.

PolyPro brush − Heavy duty polypropylene bristles provide a more aggressive cleaning performance and can more easily lift compacted dirt, debris, and sand while offering excellent scrubbing performance.

Polypropylene brush − General purpose polypropylene bristles lift lightly compacted dirt without scuffing high-gloss coated floors.

Polyester brush − Softer general purpose polyester bristles lift light debris while sweeping and gently clean while scrubbing. Perfect for sensitive floor surfaces. Polyester does not absorb water so it is preferred over Nylon in wet applications.

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

WHILE OPERATING THE MACHINE

Pick up oversized debris before scrubbing or sweeping. Pick up wire, string, twine, large pieces of wood, or any other debris that could become wrapped around or tangled in the brushes.

Drive as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine. Overlap the scrub/sweep paths by several centimeters (a few inches).

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

Adjust the machine speed, brush pressure, and solution flow as required when scrubbing. Use the lowest brush pressure and solution flow settings for best performance. If the machine is equipped with the FaST or ec−H2O system, use the FaST or ec−H2O system for the best scrubbing results.

Keep the machine moving to prevent damaging floor finishes.

If poor cleaning performance is observed, stop cleaning and refer to MACHINE TROUBLESHOOTING in this manual.

Perform the Daily Maintenance Procedures after each use (see MACHINE MAINTENANCE in this manual).

Drive the machine slowly on inclines. Use the brake pedal to control machine speed on descending inclines. Scrub with the machine up inclines rather than down inclines.

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

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

The maximum rated incline for scrubbing with the machine is 10%. The maximum rated incline during transport of the machine is14%.
