MACHINE MAINTENANCE

To keep the machine in good working condition, simplyfollow the machine’s maintenance procedures.

FOR SAFETY: Before performing any maintenanceprocedures turn the main power switch to the o position.

FOR SAFETY: When servicing machine, all repairs must be performed by a qualied service person.

AFTER EACH USE1. Empty the recovery tank and thoroughly rinse with clean water (Figure 25).

FIG. 25

2. Recharge the battery (Figure 26).

FIG. 26

FIG. 27

3. Raise the scrub head to the transport position to prevent at spot on brush (Figure 27).

AFTER WEEKLY USE1. Clean the vacuum shut-o oat with damp cloth (Figure 28) and remove any debris buildup from vacuum intake screen (Figure 29).

ATTENTION: Be careful not to get water in vacuum intake screen, vacuum damage may result.

FIG. 28 FIG. 29

2. Remove the brush and check for entangled debris (Figure 30). Replace brush if damaged or worn.

FIG. 30

3. Tilt the machine back and clean the underside of the scrub head (Figure 31).

FOR SAFETY: Before tilting machine, turn the mainpower switch to the o position and empty tanks.

FIG. 31

MAINTENANCE

4. Wipe the squeegee blades (Figure 32). Replace the blades if worn or damaged. Remove any clogged debris inside both inlet openings.


InletOpenings

FIG. 32

5. Clean the machine with an all purpose cleaner and damp cloth (Figure 33).

FOR SAFETY: When cleaning machine, do notpower spray or hose o machine. Electrical malfunction may occur.

FIG. 33

6. Clean the solution hose screen (Figure 34).

FIG. 34

VACUUM HOSE MAINTENANCE

To prevent debris buildup in vacuum system, ushvacuum hose as described below:

1. Place machine over oor drain and turn the main power switch to the o position (Figure 35).

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 o, 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 ush out debris buildup.NOTE: The vacuum hose is Y-shaped. Make sure toush out both sides (Figure 38).

FIG. 38

MAINTENANCE

SQUEEGEE BLADE REPLACEMENT

Tilt the machine back to access the squeegee blades.


To remove the squeegee blades, lift the blade retainer clip and pull the blade from the channel (Figure 39).

Retainer Clip

FIG. 39

For easy blade installation, the squeegee blades arecolor coded to match the scrub head blade channel(Figure 40).

Gray -- Outside Blade

Black -- Inside Blade

FIG. 40

To install blade, slide each blade into the appropriatechannel until retainer clip engages blade (Figure 41). The squeegee blade ribs should face away from each other.

FIG. 41

TRANSPORTING MACHINE

Before transporting machine, empty water from tanksand turn the main power switch to the o position.

FOR SAFETY: When transporting machine, get assistance or use a mechanical lift when liftingmachine.FOR SAFETY: When transporting machine, use tie-down straps to secure machine.

To wheel machine from room to room, raise the scrubhead to the transport position and push the machine forward (Figure 42).

DO NOT tilt machine on the rear wheels. Only use the rearwheels to transport machine up and down a curb.

FIG. 42

Curb

FOR SAFETY: When transporting machine, do nottilt on rear wheels and do not wheel up or down stairs. Get assistance or use a mechanical lift whenlifting machine.

MAINTENANCE

STORING MACHINE

Before storing machine, empty tanks and fully charge thebattery.

Store the machine in an open, well-ventilated, dry andclean 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 NotUse Outdoors. Do Not Expose to Rain/Moisture.Store Indoors.
