OPERATING INSTRUCTIONS NOTE: Before starting, perform the pre-start checks. PRE-START CHECKLIST 1. Check controls for proper operation. 2. Make sure all controls are in the off position 3. Be sure foot throttle is in the neutral position 4. Check all flaps for damage or wear 5. Check scrub brushes for wear 6. Fill solution tank with water and detergent TO FILL SOLUTION TANK Remove the solution lid located on the back right side of the machine as shown in figure 30.
OPERATING INSTRUCTIONS TO BEGIN THE CLEANING OPERATION 1. Lower brushes into position. DISC SCRUB DECK = NORMAL OR HEAVY CYLNDRICAL SCRUB DECK = ONE SETTING ONLY 2. Place the squeegee switch in the lower position. SQUEEGEE BLADE = LOWER 3. Move solution control knob to the desired setting and begin operation. SCRUBBING THE AVERAGE FLOOR WITH LIGHT TO MEDIUM SOILAGE In this operation, cleaning is accomplished in one pass, with simultaneous solution feed, scrubbing and dirty water pick up.
OPERATING INSTRUCTIONS THE NON-RECYCLING OR STANDARD SCRUBBING MODE – FIGURE 32 During the scrubbing process, detergent solution water from the solution tank is fed to the solution line. There it is fed to the floor where two disc scrubbing brushes work to dislodge soil. After scrubbing, the dirty solution is vacuumed from the floor and discharged into the recovery tank.
OPERATING INSTRUCTIONS SCRUBBING PATH * * * * * * Try to scrub in as straight a path as possible. Avoid bumping into posts or scraping the sides of the machine. When placing the machine in motion, avoid slamming the directional control pedal all the way forward suddenly. This is equivalent to starting out in “HIGH” and puts needless strain on the drive system. Periodically, turn the sweeping broom end for end to prevent the bristles from “settling” in one direction.
OPERATING INSTRUCTIONS POST-OPERATION CHECKLIST Check Battery Condition and recharge, if necessary. 1. Check all flaps for wear, damage and adjustment. 2. Drain and clean recovery tank. 3. Clean recovery tank screen and float. 4. Check scrub brushes for wear or damage. 5. Check rear and side squeegee for wear, damage and adjustment. DRAIN HOSE PLUG DRAIN HOSE PLUG DRAIN HOSE DRAIN HOSE Fig. 35 Fig. 36 DRAINING RECOVERY TANK Fig.
OPERATING INSTRUCTIONS When the draining operation is completed, flush the recovery drain hose as shown in figure 38. Clean the recovery tank and recovery tank screen as shown in figure 39. Close the drain hose plug, close recovery tank lid and clip the drain hose into place. Inspect the disc brushes and replace when bristles are reduced to 3/4 inch length as shown in figure 40 and 41. To order replacement brushes, see scrub brush options in this manual.
OPERATING INSTRUCTIONS Inspect the rear and side squeegee blades for wear. If the wiping edge has become rounded, remove and reinstall so the unworn edge is now the wiping edge. This process can be repeated until all four edges are worn. If the squeegee blade has become rippled, it will need to be replaced. Inspect the inner flap on the rear squeegee for wear and to ensure it has not been torn or damaged. (IF YOUR 5730 HAS CYLINDRICAL SCRUBBING, SEE CHAPTER 4.) REAR SQUEEGEE SQUEEGEE BLADE Fig. 43 Fig.
