13. FRONT 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 two 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 two 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
The squeegee assembly must have correct
deflection at each tip as well as the center. The
knobs on the squeegee linkage control the
adjustment.
