OPERATING INSTRUCTIONS
BEFORE STATING, FAMILIARIZE YOURSELF WITHTHE MACHINE AND ITS CONTROLS
(SEE “MACHINE OVERVIEW” & CONTROL PANEL DIAGRAMS)
1. Filling: Fill the solution tank with the desired amount of water and add liquid cleaning
solution to the proper dilution ratio. DO NOT USE powdered cleaning chemicals.
Powders are unlikely to dissolve thoroughly, resulting in clogging the in-line solution
filter. This can reduce or stop water flow to the brush.
2. Close lid.
3. Turn on machine by lifting the red emergency disconnect button (17) so it is in the
up position. Turn keyswitch (15) clockwise to “on” position and turn on main power
switch (16).
4. Adjust main speed control (21) to full counter-clockwise position.
5. Lower brush assembly.
- To lower the brush, first push the pedal (10) slightly outward on the machine
(unlock it), and then release it slowly or by pressing “brush down” switch (19)
on Deluxe models.
- To lift the brush, press the pedal (10) down until lift mechanism engages or by
pressing ”brush up” switch (19) on Deluxe models.
- Brush will come on automatically when brush in on the floor and “forward” (5)
or “reverse” (3) handles are squeezed and remain on approximately 5 seconds
after release.
6. Adjust solution control feed lever.
7. Select vacuum operations:
- “Vacuum On” mode (23)
Vacuum will remain on until switched to the “off” position
- “Vacuum Auto” mode (23) –
Vacuum will come on automatically when “forward” or “reverse” handle
is squeezed, and scrubhead is on the floor. The brush and vacuum will
remain on approximately 5 minutes.
8. Lower squeegee assembly by lowering handle (1).
9. Squeeze “forward” handle (5) and adjust forward speed (21) as desired.
After Use:
1. Turn off solution feed.
2. Raise squeegee assembly.
3. Turn off vacuum motor.
Solution and recovery tanks should be emptied after every use.
MAINTENANCE:
Daily 1. Clean float assembly & squeegee blades. Vac filter
2. Recharge batteries (check battery acid levels before and after charging).
Monthly 1. Check wear on squeegee blades.
2. Grease front wheels.
3. Grease pivot points on brush motor assembly.
Every 500 hours check condition of carbon brushes on vacuum motor and brush drive motor.

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.
