SQUEEGEE ADJUSTMENTS
The squeegee set up is pre adjusted at the factory. Adjustments may be required to get optimum
performance for different floors and conditions.
1 Ensure that the scrubber is on a relatively flat surface. Turn on the main power switch and turn the key
switch clockwise to the on position. Raise the scrubhead off the floor. Turn the vacuum switch to the
“vacuum only” position.
2 Turn the speed control knob counter clockwise to the low speed position. Lower the squeegee (item 1)
to the floorand squeeze the forward control handle, moving the machine one or two feet forward to
check the rear squeegee blade (item 8) 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 4) in order to adjust the castor height. If the squeegee
blade is deflecting too much, the castors need to be lowered to control the down pressure. Lower the
castor by turning the exposed threaded stem (item 9) on the castor clockwise. Make the adjustment a
few turns at a time. Repeat Step 2.
5 If the blades are not deflecting enough, raise the castor by turning the stem counter clockwise to adjust
the castor height to allow more down pressure on the squeegee. Repeat Step 2.
6 Make sure that there is an even deflection on the entire length of the rear blade. Adjust the castors and
retighten the wing jam nuts to lock the castor setting in place.
7 Pitch adjustment is necessary if the outer ends on the squeegee blade does 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, lower the squeegee to the floor. Loosen the lock nut (item 3) in the turnbuckle
assembly. Turning the turnbuckle (item 2) clockwise or counter clockwise controls the forward and
backward pitch of the squeegee. Having the rear blades deflected uniformly along the entire length is
the desired set up.
9 Repeat Step 2 until the desired set up is achieved.
10 In certain applications where a non-slotted front wiper blade (item 6) is needed, detach the squeegee
assembly by loosening the wing bolts (item 7). Unlock the clamp on the front squeegee to release the
straps and flip the blade over to the non-slotted side. Reattach straps and lock the clamp back in place.
11 You can also easily replace the rear blade by unlatching the latch (item 5) and removing the straps by
sliding them off the assembly.
