Maintenance For The Squeegee
To remove the squeegee, follow this procedure:
1. Remove the squeegee assembly by loosening the two knobs
that attach the squeegee to the machine. Pull the squeegee
assembly off. See fi gure #26.
2. Inspect the squeegee blade.
3. If the blade is worn, turn the blade so that a new edge is in the
wiping position.
4. Reinstall squeegee assembly on the machine.
How To Adjust The Squeegee
The following adjustments are set at the factory, however they may
require slight adjustment.
Adjusting Squeegee Pressure:
To adjust the pressure, refer to Figure #27. Proper adjustment will
produce a uniform fl are along the rear blade when the machine is
moved forward. To increase pressure, tighten the nuts on each side
of the swing arm. To decrease the pressure, loosen the nuts on each
side.
Adjusting Squeegee Tilt:
The tilt of the squeegee causes the rear blade to raise up in the center
or on the ends, depending on which direction the tilt is changed. For
tilt adjustment, refer to fi gure # 28. Loosen left and right screw “X”. In
order to bring the rear blade down in the center, tip “Y” down. To bring
both ends down, tip “Y” up. Make very small adjustments and try it
until a uniform fl are is achieved. Changing the tilt may also require
readjusting the squeegee pressure.
