2. Wash cloth filter bag by hand with a mild detergent
as needed. Let bag dry thoroughly before

maintain good suction performance.

cause vacuum motor to overheat.
3. Clean ball float screen inside tank after every use.
Lift float screen assembly out of tank (Figure 15).

ATTENTION: Always have ball float screen in
place before vacuuming. During wet vacuuming,
the float screen protects the vacuum motor from
water overflows. During dry vacuuming, the float
screen can provide limited protection to vacuum
motor from larger debris in case filter bag breaks.
4. Once each month, spray ball bearings in front
swivel caster with silicone spray.
5. Clean squeegee blades with a cloth whenever
they start to leave streaks on the floor. Replace
squeegee blades when they become worn.
6. Wipe machine housing with a cloth and mild
detergent.
7. Inspect vacuum hose regularly for holes, loose
cuffs or clogged debris.
8. Inspect power cord for damage, replace if
damaged. Coil cord neatly after each use.
WARNING: Do Not Operate With Damaged
Power Cord. Do Not Modify Plug. Unplug Power
Cord Before Servicing Machines.
If the supply cord is damaged or broken, it must
be replaced by the manufacturer or it's service
agent or a similarly qualified person in order to
avoid a hazard.
9. Monthly, check vacuum motor brushes for wear,
replace brushes when 0.38 in / 10 mm or less in
length.
FOR SAFETY: All repairs must be performed by a
qualified service person.
