MAIN SQUEEGEE COMPONENTS
CHECKING and Adjusting the Rear Main Squeegee
Flare
NOTE: Perform check # 16 before proceeding to
make adjustments
1. Park the machine on a flat surface. Lower the
squeegee.
2. Turn the machine off and engage the parking brake.
3. Open the access doors to the disc scrub brushes.
4. Locate & remove the pull pins for the side
squeegees, remove the side squeegees.
5. Lower the squeegee assembly
6. Release the quick-disconnect at the back of the rear
squeegee.
7. Loosen the locking nut on the squeegee caster and
screw the caster up until it clears the floor. With
the squeegee straight up on the floor (no flare),
adjust the caster until it clears the floor by ½” (12.7
mm). Use a ½” (12.7 mm) shim spacer of metal or
wood as a feeler gauge for this procedure. This is a
starting reference.
PREVENTATIVE MAINTENANCE
8. Locate the squeegee lift arms on each side of the
machine.
9. Loosen the bolt which attaches the upper squeegee
lift arm to the squeegee mounting plate on each
side.
10. Locate and loosen both jam nuts on each squeegee
tilt adjustment link and back them away from the
gussets. The rear squeegee is now free to be
aligned with the floor. Lift the squeegee tool by hand
and allow it to rest back on the floor, this will seat
the tool to the floor. Again it should stand straight on
the floor with no flare.
11. Check the squeegee rubber to make sure the
squeegee makes contact with the floor all the way
around.
12. At each squeegee arm mount, turn the two jam nuts
on the tilt adjusting link until they both make contact
with the mounting plate on each side.
13. Tighten the jam nuts on each mount plate. Then
tighten the bolt on top of each of the two upper
squeegee arms.
14. Tighten the nut on the caster.
