MAINTENANCE
MACHINE MAINTENANCE
To keep the machine in good working condition, simply
follow the machine’s maintenance procedures.
FOR SAFETY: Before performing any maintenance
procedures turn the main power switch to the o
position.
FOR SAFETY: When servicing machine, all repairs
must be performed by a qualied service person.
AFTER EACH USE
1. 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 USE
1. 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 main
power switch to the o position and empty tanks.
FIG. 31
T1 Battery - Service Information 9008675 (6-11) 3-3
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 o position and empty tanks.
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 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, ush
vacuum 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 to
ush out both sides (Figure 38).

MAINTENANCE
SQUEEGEE BLADE REPLACEMENT
Tilt the machine back to access the squeegee blades.
FOR SAFETY: Before tilting machine, turn the main
power switch to the o position and empty tanks.
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 are
color coded to match the scrub head blade channel
(Figure 40).
Gray -- Outside Blade
Black -- Inside Blade
Gray
Black
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. 41
TRANSPORTING MACHINE
Before transporting machine, empty water from tanks
and turn the main power switch to the o position.
FOR SAFETY: When transporting machine, get
assistance or use a mechanical lift when lifting
machine.
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. 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.
T1 Battery - Service Information 9008675 (6-11) 3-5
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.
