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

) 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

) in order to adjust the caster height. If the squeegee

blade is deflecting too much, the casters (item

) need to be lowered to control the down pressure.

Lower the caster by turning the exposed threaded stem (item

) 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 lock nut (item

) in the turnbuckle assembly. Turning the turnbuckle (item

) 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

) is needed, detach the rear

squeegee assembly by loosening the two wing bolts (item

). Unlock the toggle clamp (item

) on the

front squeegee to release the front long strap (

) and slide the front short strap (item

). 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

) and removing the two rear

straps (items

) by sliding them off the assembly. You can then flip the blade over in order to

use a new edge for better wiping action.

OFF-AISLE WAND

The

SCV

is equipped with a ready-to-use built-in telescoping off-aisle wand (item

) system for use in hard

to reach areas. This integrated system eliminates attaching hose for use and detaching hoses for storage.
By turning the

pump switch

ON (located on the control console) and flipping a lever that doubles as the

wand hanger, the off-aisle wand is ready to use in seconds. Flipping the lever up (item

) diverts the

vacuum flow from the main rear squeegee intake (item

) to the off-aisle wand intake (item

After use,

simply flip the lever back down to its normal position to use as the hand hanger. The wand is also
equipped with the patented flip-flop tool that allows the operator to switch from scrub brush to squeegee
tool by just rotating the tool end.
