REAR SQUEEGEE ADJUSTMENT
1. Ensure that the scrubber is on a relatively flat surface. Turn on the key switch and lower the
squeegee to the floor using the squeegee lift lever. This turns the vacuum motor on.
2. Move the scrubber one or two feet forward slowly while someone behind the machine checks
the rear squeegee blade (item A ) for uniform deflection to the floor.
3. If uneven deflection or lay is evident, minor adjustments may be necessary to avoid streaking
and uneven wear on the blade.
4. To correct this, loosen the wing jam nut (item
B ) in order to adjust the caster height. If the
squeegee blade is deflecting too much, the casters (item D ) need to be lowered to control the
down pressure. Lower the caster by turning the exposed threaded stem (item C ) on the
caster clockwise. Make the adjustment a few turns at a time. Repeat step 2 .
5. If the blades are not deflecting enough, raise the caster by turning the stem counter-
clockwise to adjust the caster height to allow more down pressure on the squeegee. Repeat
step 2.
6. Make sure there is even deflection on the entire length of the rear blade. Adjust the casters
and retighten the wing jam nuts to lock the caster setting in place.
7. Pitch adjustment is necessary if the outer ends on the squeegee blade do not contact the
floor and there is too much deflection in the middle area or if the outer ends are over
deflected and there is no contact in the middle.
8. To adjust the pitch, Repeat step 2.
9. Loosen the two wing jam nuts (item
E ) that lock the pitch angle. Turning the knob (item F )
clockwise or counter-clockwise controls the forward and backward pitch of the squeegee.
Having the rear blades deflected uniformly along its entire length is the desired set-up.
10. Repeat step 2 until desired set-up is achieved.
11. In certain applications where a non-slotted front wiper blade (item
G ) is needed, detach the
rear squeegee assembly by loosening the two wing bolts (item H ). Unlock the toggle clamp
(item I ) on the front squeegee to release the front long strap (item J ) and slide the front short
strap (item K ). Flip the blade over to the non-slotted side. Reattach the straps and lock the
clamp back in place.
12. You can also easily replace the rear blade by unlatching the latch (item
N ) and removing the
two rear straps (items L & M ) by sliding them off the assembly. You can then flip the blade
over in order to use a new edge for better wiping action.
