MAINTENANCE
FIGURE 1
Whenever the vacuum system does not perform
properly, the entire system should be cleaned and
inspected, following the maintenance checklist
below.
1
Remove the squeegee from the machine and
clean it thoroughly.
2
Inspect the squeegee blades. If the wiping
edge of the rear blade is damaged or worn to
a radius, turn it around or over so a new
edge with a sharp corner faces toward the
front of the machine.
3
See Figure 1.
Disconnect squeegee hose
“A” from
left side
of recovery tank cover “B”.
Park the machine outside or near a floor
drain and use a garden hose to “back flush”
dirt down and out of squeegee hose “A”.
CAUTION!
Do not flush hose “C” unless it is disconnected
from the vacuum motor.
4
Remove cover “B” from the recovery tank
(see Figure 1). Rinse all dirt from cage “E”
and ball “F”.
5
Check the gasket on recovery tank cover “B”.
It must seal air-tight against the top of the
tank.

Check drain hose cap “D”. Replace the cap if it does not seal air-tight.
If the machine still does not pick up after completing this checklist, see the
Troubleshooting
section of this
chapter for additional information.
