Maintenance For The Squeegee

1.Remove the squeegee assembly by loosening the two knobs that attach the squeegee to the machine. Pull the squeegee assembly off. See figure #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.

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 flare 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 figure # 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 flare is achieved. Changing the tilt may also require readjusting the squeegee pressure.
