SQUEEGEE MAINTENANCE
If the squeegee leaves narrow streaks or water, the blades may be dirty or damaged. Remove the squeegee, rinse it under warm water and inspect
the blades. Reverse or replace the blades if they are cut, torn, wavy or worn.
To Reverse or Replace the Rear Squeegee Wiping Blade...
1 See Figure 4-5. Raise the squeegee tool off the floor, then unsnap the Latch (AA) on the squeegee tool.
Remove the Tension Strap (AB).

3 Slip the Rear Blade (AJ) off the alignment pins.
4 The squeegee blade has 4 working edges as shown below. Turn the blade so a clean, undamaged edge faces toward the front of the machine.
Replace the blade if all 4 edges are nicked, torn or worn to a large radius.
5 Install the blade, following the steps in reverse order and adjust the squeegee tilt.
To Reverse or Replace the Front Squeegee Blade...

SQUEEGEE ADJUSTMENT
There are two squeegee tool adjustments possible, tilt and height.
Adjust the squeegee tilt whenever a blade is reversed or replaced, or if the squeegee is not wiping the floor dry.
1 Park the machine on a flat, even surface.
Lower the squeegee, move the machine ahead slightly and adjust the squeegee tilt and height using the Squeegee Tilt Adjust Knob (30) and
2
Squeegee Caster Lock Knobs (32) so that the rear squeegee blade touches the floor evenly across its entire width and is bent over slightly as
shown in the squeegee cross section.
3 Squeegee height is pre-set at the factory but may require periodic adjustment due to caster wear. Proper squeegee height is achieved when
the rear squeegee blade touches the floor evenly across its entire width and is bent over slightly with the caster wheel just touching the floor.
a. Loosen Caster Lock Knobs (32).
b. Thread Casters (AE) up or down as required to achieve proper height and ensure blade position is uniform left to right.
c. Tighten Caster Stops (AF) against squeegee mount (AG).
d. Tighten Squeegee Caster Lock Knobs (32) against squeegee mount to lock adjustment.
4 The Tilt Adjust Knob (30) is used to adjust the tool tilt/angle for uniform contact from center to tips of blade.
a. Loosen Tilt Stop Knob (AH).
b. Turn Tilt Adjust Knob as required to adjust.
c. Tighten Tilt Stop Knob (AH) against the squeegee mount to lock adjustment.
