Maintenance and Adjustment
Lift Actuator Limit Adjustment
To protect the lift actuator from traveling too far, it
contains internal limit switches for minimum and
maximum travel. This adjustment requires the use of
the Actuator Power Cord Adapter
(99)
(PN 56407502)
shown to the right.
Important:
If this procedure is being completed on a
new actuator, it is important that you check
the orientation of the nut and springs inside
the spring housing. Refer to
1. This procedure is best performed on a work bench.
Remove the
2. Connect the Power Cord Adapter
(99)
to the positive and negative battery terminals of the Focus II
machine.
3. Connect the other end of Power Cord Adapter
(99)
to the motor’s power connector. (The position switch
connector is not needed for this procedure.)
4. While holding the spring housing
(2C)
from turning, press the For/Rev switch on the Adapter
(99)
to
move the spring housing
(2C)
until the actuator reaches its limit switch and the motor stops:
•
For Boost and Disk decks, move the actuator to its extended position.
•
For Cylindrical decks, move the actuator to its retracted position.
5. Rotate the spring housing
(2C)
until the distance between the spring housing and gear housing
(2M)
is
as follows:
•
3.94±0.06 inches (extended) for Disk and Boost decks
•
0.75±0.09 inches (retracted) for Cylindrical decks.
Important:
After the limit is adjusted and
until the actuator is back in the
machine, make sure not to rotate the
spring housing relative to the motor
housing.
6. Before disconnecting the Adapter cord
(99)
, move the spring housing back to the
approximate position it was in when you
removed it from the machine. Leave the
adapter cord connected to the battery,
but unplug it from the motor while
reinstalling the actuator.
7. Reinstall the actuator on the machine.
8. If necessary, use the adapter cord to raise or lower the mechanism to make it easier to reinstall the scrub
deck. Take care to not allow the spring housing to rotate.
