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.

replace brushes when 0.38 in / 10 mm or less in
length.
