OPERATION HOW THE MACHINE WORKS BRUSH AND PAD INFORMATION Conventional scrubbing: When using the conventional scrubbing mode, water and detergent mixture from the solution tank flows to the floor and the rotating brush(es)/pad(s) scrub the floor clean. As the machine moves forward, the squeegee with vacuum suction picks up the dirty solution from the floor into the recovery tank. For best cleaning results use the appropriate brush or pad for your cleaning application.
OPERATION INSTALLING BRUSH/PAD - 3 Lug Disk MACHINE SETUP ATTACHING SQUEEGEE ASSEMBLY FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, remove key and set parking brake if equipped. FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, remove key and set parking brake if equipped. 1. Step down on the scrub head lift pedal to raise the scrub head off the floor (Figure 8). 1.
OPERATION Dual disk model - Turn the brush motor hub until the lug slot with spring clip is visible. Position the three lugs into the motor hub slots and give the pad driver/brush a quick turn towards the spring clip (Figure 11). View through the scrub head window to align lugs. NOTE: The left and right disks engage the hubs in opposite directions.
OPERATION 4. To remove the pad driver(s)/brush(es), raise the scrub head and press the yellow plunger button with foot or hand (Figure 17). Pad will drop to floor. FIG. 17 INSTALLING PAD - Orbital 2. Install the backer pad, retaining strips facing outward, to bottom of scrub head (Figure 20). Make sure pad is centered on scrub head. FIG. 20 3. Attach the work pad to the backer pad (Figure 21).
OPERATION 2. Remove the debris tray by sliding it out from the scrub head (Figure 23). FILLING SOLUTION TANK FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, remove key and set parking brake if equipped. Remove the solution tank lid and fill the solution tank. Stop filling tank when the level reaches the “3/3” mark on the solution tank drain hose indicator (Figure 27). ec-H2O Scrubbing - Fill solution tank with only cool clean water (less than 70°F/21°C).
OPERATION ec-H2O NanoClean WATER CONDITIONING CARTRIDGE (ec-H2O model) The ec-H2O system is equipped with a water conditioning cartridge (Figure 29). The cartridge is designed to protect the machine’s plumbing system from potential scaling. The cartridge is required to be replaced when it reaches its maximum water usage or expiration time of when the cartridge was activated, which ever comes first.
OPERATION To install the accessory clips, hook the clip over the rail and push downward until it snaps into position. To remove the accessory clip, reach under the clip and carefully pull the latch tab downward to release from rail. (Figure 33) MACHINE OPERATION FOR SAFETY: Do not operate machine unless operator manual is read and understood. PRE-OPERATION CHECK LIST - Sweep area and remove any obstructions. - Check brushes/pads for wear and damage. - Check squeegee blades for wear and damage.
OPERATION ATTENTION: If cleaning detergent is accidentally cycled through ec-H2O system, immediately turn the ec-H2O system off. Drain solution tank, refill with cool water and operate the ec-H2O system to flush out detergent.
