CASTER ADJUSTMENT
1. If only caster adjustment is required, stop the engine and set the parking
brake.
2. Loosen the wing nuts on top of the caster stems. Turn the caster stems to
raise or lower the casters. If too much flare was experienced, lower the caster.
If too little flare was observed, raise the casters. Adjust the casters so that both
are equal in adjustment.
3. Tighten the wing nuts without disturbing the adjustment.
4. Retest the squeegee.
PITCH ADJUSTMENT
If the pitch adjustment is required, it is usually easiest to adjust both pitch and casters
at the same time.
1. Park the machine on a level floor and set the parking brake. Turn the engine
off.
2. Loosen the wing nuts on top of the caster stems and adjust the casters up
several turns. Leave loose.
3. Locate the pitch adjusting screws on the squeegee support arm. There are two
adjusting screws. Loosen all four locking nuts (2 per screw) and back the nuts
away from the bracket several turns.
4. At the forward end of each adjusting screw, locate and loosen the pivot bolts
and nut. Do not remove the nuts.
5. With the hardware loosened, crank the engine, set the throttle to medium
speed. Turn the steering wheel completely to the right. Be sure that the
parking brake is locked. Lower the squeegee.
6. With the squeegee rubber resting on the floor, check that the rear rubber is
standing on the floor and making contact throughout its width. If not, lift and
drop by hand until contact is made across.
7. With the squeegee in this position, turn all four locking nuts by hand until they
are snug against the bracket. Do not wrench tighten yet.
8. Using a ¼” drill bit as a gage, lower both casters until the ¼” drill bit can pass
between the wheel and the floor.
