2. REAR SQUEEGEE
The front blade allows solution to pass through
channels in the blade into the squeegee assembly
while maintaining vacuum to provide lift. The front
blade has four wear surfaces and can be rotated for
extended life. The front blade should not require
regular replacement under normal use.
The rear blade wipes the floor to a near dry
condition. It is important the rear blade be in good
condition to properly do its job. As with the front,
each squeegee blade assembly has four wear
surfaces for extended service.
Check both the front and rear squeegee blades for
damage, wear, and adjustment each day in the pre-
run check. Change the front blade if it is torn or has
an uneven edge. Change the rear blade if it is less
than 1/2 the original thickness.
ADJUSTING SQUEEGEE
Adjusting the squeegee is a two-part process. First,
the squeegee assembly must have correct pitch in
order for the squeegee blade to have the same
deflection at each tip as well as the center. The
knob on the squeegee linkage controls the pitch
adjustment. The second adjustment is the
deflection. Knobs on each end of the squeegee
control this.
