MAINTENANCE
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 25.
2. Inspect the squeegee blades.
3. If the blades are worn, unclamp bands and turn the blade so that a new
edge is in the wiping position (see fi gures 25A and 25B).
4. Reinstall squeegee assembly on the machine.
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. Turn
the adjusting screw clockwise or counterclockwise (see fi gure 26), to
achieve uniform squeegee blade fl are.

thorized personnel only.
