15. SQUEEGEE ACTUATOR
REMOVAL/REPLACEMENT
FOR SAFETY: Before leaving or servicing
machine, stop on a level surface, turn off
machine and set parking brake.
1. Remove squeegee to gain access to lift system.
2. Lower squeegee lift linkage, if possible, by
pressing bottom of vacuum/squeegee switch
and turn key to the off position.
3. Remove lower clevis pin by removing rue ring
and washer from clevis pin, then pull pin out
from squeegee lift bracket and actuator.
4. Remove upper clevis pin (ball detent type) by
pulling on it’s ring (located on left side), then pull
it out from the frame and actuator. Pull actuator
down to remove from the machine, make sure
not to allow actuator barrel position to move.
5. Disconnect actuator from wire harness.
6. Reverse steps to install.
SQUEEGEE ACTUATOR ADJUSTMENT
The actuator will need to be adjusted when
replaced. The actuator needs to be set such that it
does not bind against itself in the raised/retracted
position, and does not bind against the axle in the
lowered/extended position.
To adjust the actuator:
1. While holding actuator barrel to prevent it from
spinning, apply power to the actuator such that it
is fully extended. Positive power to white wire,
and negative/ground to black. Limit switch
within actuator will stop it.
2. Turn barrel out one or more full turns to assure
that when it is retracted it will not bind against
itself.
3. While holding actuator barrel to prevent it from
spinning, apply power to the actuator such that it
is fully retracted. Positive power to black wire,
and negative/ground to white wire. Limit switch
within actuator will stop it.
4. With actuator fully retracted, turn barrel in until it
touches the base of the threaded shaft.
5. At the bottomed out position, turn the barrel out
1 full turn
, then enough to allow connection to
lift linkage.
6. Connect actuator to lift linkage and check that in
the raised/retracted position it does not bind
against itself, and in the lowered/extended
position does not bind against the axle
7. If further adjustment is needed, disconnect the
actuator from squeegee lift linkage and turn the
barrel one half-turn at a time in to eliminate
binding against axle, or out to eliminate binding
against itself.
