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 raise the scrub
head assembly off the floor. Set the squeegee/ vacuum switch to the automatic mode.

2. Turn the speed control knob counter-clockwise to the low speed position. Squeeze the forward control lever to lower

the squeegee (item 1) to the floor. Move 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 caster height. If the squeegee blade is

deflecting too much, the casters need to be lowered to control the down pressure. Lower the caster by turning the
exposed threaded stem (item 9) on the caster clockwise. Make the adjustment a few turns at a time.

5. Repeat step 2.
6. If the blades are not deflecting enough, raise the caster by turning the stem counter-clockwise to adjust the caster

hieght to allow more down pressure on the squeegee. Repeat Step 2.

7. 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 lockthe caster setting in place.

8. 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.

9. To adjust pitch, lower the squeegee to the floor. Loosen the lock nut (item 3) in the turnbuckle assembly. Turning

the turnbuckle (item 2) clockwise or counterclockwise controls the forward and backward pitch of the squeegee.
Having the rear blades deflected uniformly along its entire length is the desired setup.

10. Repeat Step 2 until the desired setup is achieved.
11. In certain applications where a non-slotted front wiper blade (item 6) is needed, detach the squeegee assembly by

loosening the wing bolts (item7). 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.

12. You can also easily replace the rear blade by unlatching the latch (item 5) and removing the straps by sliding them

off the assembly.
