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 3. Raise the squeegee tool off the floor, then unsnap the Center Latch (A) on the squeegee tool.
2 Remove the Wing Nut (B) from each end of the squeegee, then remove the Tension Straps (C).
3 Slip the rear blade off the alignment pins.
4 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points 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.
To Reverse or Replace the Front Squeegee Blade...
1 Raise the squeegee tool off the floor, then loosen the (2) Thumb Nuts (D) on top of the squeegee and remove the squueegee tool from the mount.
2 Remove all the wing nuts that hold the front blade in place, then remove tension strap and blade.
3 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all
4 edges are nicked, torn or worn to a large radius.
4 Install the blade, following the steps in reverse order and adjust the squeegee.
SQUEEGEE ADJUSTMENT
There are two major squeegee tool adjustments, height and angle. The recommended adjustment steps are to set the tool angle first, then adjust the blade height.
Adjusting the Squeegee Angle
Adjust the squeegee angle 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 and lower the squeegee. Then drive the machine forward enough to have the squeegee blades fold over to the
rear.
2 Loosen the Lock Wing Nut (G) (hand tightened). This secures the squeegee mount angle from easily vibrating out of adjustment.
3 Turn the Adjustment Knob (H) to tilt the tool forward or backwards, until the rear squeegee wiping blade touches the floor evenly across its entire width.
4 Re-tighten by hand the Lock Wing Nut (G).
Adjusting the Squeegee Blade Height
Adjust the squeegee height whenever a blade is reversed or replaced, or if the squeegee is not wiping the floor dry. The squeegee blade height is easily adjustable
at the caster wheels. To adjust...
1 Park the machine on a flat even surface and lower the squeegee. Then drive the machine forward enough to have the squeegee blades fold over to the
rear.
2 Loosen both the lock adjustment Wing Nuts (E) (need to be hand tightened only) located on the top of the caster mount bracket.
3 Rotate the Adjustment Knobs (F) CW (clockwise) to lift the squeegee and CCW (counter clockwise) to lower it. A starting point when replacing the blades
is to adjust the caster mounting bracket so it is level (parallel) to the top of the squeegee tool. Note: The Right and Left caster wheels must be adjusted
equally to maintain level and even blade pressure.
4 Re-tighten the lock adjustment Wing Nuts (E) and test for proper squeegee pick-up.
