ATTENTION: Be careful not to get water in vacuum intake screen, vacuum damage may result. FOR SAFETY: When servicing machine, all repairs must be performed by a qualified service person. AFTER EACH USE 1. Empty the recovery tank and thoroughly rinse with clean water (Figure 25). FIG. 28 FIG. 29 2. Remove the brush and check for entangled debris (Figure 30). Replace brush if damaged or worn. FIG. 25 2. Recharge the battery (Figure 26). FIG. 30 3. Tilt the machine back and clean the underside of the scrub head (Figure 31). FOR SAFETY: Before tilting machine, turn the main power switch to the off position and empty tanks. FIG. 26 3. Raise the scrub head to the transport position to prevent flat spot on brush (Figure 27). FIG. 31 FIG. 27 3-2 T1 Battery - Service Information 9008975 (6-11) MAINTENANCE 4. Wipe the squeegee blades (Figure 32). Replace the blades if worn or damaged. Remove any clogged debris inside both inlet openings. FOR SAFETY: Before tilting machine, turn the main power switch to the off position and empty tanks. VACUUM HOSE MAINTENANCE To prevent debris buildup in vacuum system, flush vacuum hose as described below: 1. Place machine over floor drain and turn the main power switch to the off position (Figure 35). Inlet Openings FIG. 32 5. Clean the machine with an all purpose cleaner and damp cloth (Figure 33). FOR SAFETY: When cleaning machine, do not power spray or hose off machine. Electrical malfunction may occur. FIG. 33 6. Clean the solution hose screen (Figure 34). FIG. 35 2. Place a dry towel over the vacuum intake screen to prevent water from entering vacuum motor (Figure 36). 3. With water turned off, insert a garden hose into the vacuum intake hose as shown (Figure 37). FIG. 36 FIG. 37 4. Slowly turn on water to prevent back-splash if vacuum system is clogged. Increase water pressure to flush out debris buildup. NOTE: The vacuum hose is Y-shaped. Make sure to flush out both sides (Figure 38). FIG. 34 FIG. 38 T1 Battery - Service Information 9008675 (6-11) 3-3 MAINTENANCE SQUEEGEE BLADE REPLACEMENT TRANSPORTING MACHINE Tilt the machine back to access the squeegee blades. FOR SAFETY: Before tilting machine, turn the main power switch to the off position and empty tanks. Before transporting machine, empty water from tanks and turn the main power switch to the off position. To remove the squeegee blades, lift the blade retainer clip and pull the blade from the channel (Figure 39). FOR SAFETY: When transporting machine, get assistance or use a mechanical lift when lifting machine. Retainer Clip FOR SAFETY: When transporting machine, use tie-down straps to secure machine. To wheel machine from room to room, raise the scrub head to the transport position and push the machine forward (Figure 42). DO NOT tilt machine on the rear wheels. Only use the rear wheels to transport machine up and down a curb. FIG. 39 For easy blade installation, the squeegee blades are color coded to match the scrub head blade channel (Figure 40). Gray -- Outside Blade Gray Black Black -- Inside Blade FIG. 40 To install blade, slide each blade into the appropriate channel until retainer clip engages blade (Figure 41). The squeegee blade ribs should face away from each other. FIG. 42 Curb FOR SAFETY: When transporting machine, do not tilt on rear wheels and do not wheel up or down stairs. Get assistance or use a mechanical lift when lifting machine. FIG. 41 3-4 T1 Battery - Service Information 9008975 (6-11) MAINTENANCE STORING MACHINE Before storing machine, empty tanks and fully charge the battery. Store the machine in an open, well-ventilated, dry and clean area less than 113°F/45°C in the upright position. Raise the scrub head to the transport position. If storing machine in freezing temperatures, make sure to purge all water from solution system. To purge water from solution system, empty solution tank, and operate the machine as normal for approximately 15 seconds. WARNING: Electrical Shock Hazard. Do Not Use Outdoors. Do Not Expose to Rain/Moisture. Store Indoors.
