SCRUB DECK ACTUATOR ADJUSTMENT
The actuator will need to be adjusted when
replaced.
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
only enough to allow connection to slide link.
6. Connect actuator.
7. Check travel of actuator during operation.
