SQUEEGEE BLADES
The scrub head has 2 sets of 2 squeegee blades
on the front and back. These blades squeegee up
the solution off the floor in the forward and
reverse directions. The front and rear squeegee
blades (with the many corrugations) should be
checked for damage and wear daily. When the
inside wiping edge of the front and rear
(corrugated) blades become rounded or have
tears in them, they will not pick up solution
properly. Replace any worn or damaged
squeegee blades. The inside squeegee blades
(the ones with the slots) normally only need to be
checked monthly.
REPLACING SQUEEGEE BLADES
1. Unplug the power cord from the wall outlet.
WARNING: Hazardous Voltage. Shock
Or Electrocution Can Result. Unplug
Power Cord Before Working On Machine.
2. Raise the scrub head by stepping on the
scrub head lift lever with your foot.
