REAR SQUEEGEE ADJUSTMENT
1. Ensure that the scrubber is on a relatively flat surface. Turn on the key switch and
select the Vacuum only mode. This lowers the squeegee to the floor and 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.
