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.
