HOW THE MACHINE WORKS

The scrub components of the machine are a solution tank, scrub brushes or pads, a squeegee, a vacuum fan, and a recovery tank.‌‌​⁠‍‌​​‍⁠​​‍⁠‌‌‌⁠​​​​​​​‌​‍​​​‌​⁠​​‍​‌⁠⁠‍‌‌‌‍‍‌‍‌‌‌⁠⁠‍⁠‍⁠‍‌

With conventional scrubbing, water and detergent, from the solution tank, flow to the floor through a solution valve to the scrub brushes or pads. The brushes or pads scrub the floor. As the machine moves forward, the squeegee wipes the dirty solution off the floor, which is then picked up and drawn into the recovery tank.

The steering handles control the direction and speed of the machine in forward or reverse. By rotating the steering handles forward, the machine propels forward. By rotating the handles towards you, the machine propels backward.

Three different widths of scrub heads and squeegees are available for the machine.

The scrub head widths are as follows; the model 700 (700 mm (28 in)), the model 800 (800 mm (32 in)), and the model 900 (900 mm (36 in)). The 700 mm (28 in) squeegee is used with the 700 model scrub head, as well as the 800 mm (32 in) with the model 800, and the 900 mm (36 in) with the model 900.

FaST SCRUBBING SYSTEM (OPTION)

The FaST (Foam Scrubbing Technology) system operates by injecting the FaST PAK concentrate agent (A) into the system with a small amount of water and compressed air. This mixture creates a large volume of expanded wet foam.‌‌​⁠‍‌​​‍⁠​​‍⁠‌‌‌⁠​​​​​​​‌​⁠​​​‌​⁠​​​‍‌‍‌‍‍⁠​‌‍​‌‌‌‌‍​⁠​‌‌‌‌

The expanded foam mixture is then dispersed onto the floor (B) while the machine is scrubbing. When the squeegee picks up the mixture, the patented foaming agent has collapsed and is recovered into the recovery tank.

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

ec-H2O NanoClean SCRUBBING SYSTEM (ec-H2O Model)

When using the ec-H2O NanoClean technology, normal water passes through a module where it is electrically converted into a cleaning solution. The electrically converted water attacks the dirt, 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 with all double scrubbing applications.

OPERATION

BRUSH AND PAD INFORMATION

For best results, use the appropriate brush or pad for the cleaning application. Listed below are brushes and pads and the applications for which each is best suited.‌‌​⁠‍‌​​‍⁠​​‍⁠‌‌‌⁠​​​​​​​‌‌​​​​‌​⁠​​⁠‌⁠‍⁠​​‌⁠⁠‍‌‌‍⁠​‍‍⁠‌​‌‌‌

Polypropylene brush (Cylindrical and Disk) - General purpose polypropylene bristles lift lightly compacted dirt without scuffing high-gloss coated floors.

Nylon brush (Cylindrical and Disk) - Softer nylon bristles are recommended for scrubbing coated floors. Cleans without scuffing.

Super AB brush (Cylindrical and Disk) - Nylon fiber with an abrasive grit to remove stains and compacted dirt. Aggressive action on any surface. Performs well on buildup, grease, or tire marks.

High productivity stripping pad (Black) - For aggressive stripping of heavy finishes or sealers, or for very heavy duty scrubbing. This pad can only be used with the grip pad driver, not the tufted pad driver.

Stripping pad (Brown)- For stripping of floor finish to prepare the floor for recoating.

Scrubbing pad (Blue) - For medium to heavy- duty scrubbing. Removes dirt, spills, and scuffs.

Buffing pad (Red) - For light duty scrubbing without removing floor finish.

Polishing pad (White) - For maintaining highly polished or burnished floors.

OPERATION

WHILE OPERATING THE MACHINE

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

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

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

Adjust the brush pressure and solution flow as required when scrubbing. Use the lowest brush pressure and solution flow settings for best performance.

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

Operate the machine slowly on inclines. Scrub with the machine up inclines rather than down inclines.

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 climb and descent incline with empty tanks is 14.1%, with full tanks is 10.5%.
