Lift Actuator Limit Adjustment
To protect the lift actuator from traveling too far, it contains
two internal limit switches for minimum and maximum
travel. The minimum travel is adjusted by turning the
leadscrew nut, and the maximum travel (or length) is
adjusted by turning the dial at the top of the leadscrew motor.
This adjustment requires the use of the Actuator Power Cord
Adapter
(1)
(PN 56407502) shown to the right.
1.
Remove the front nose from the machine.
2. Connect the Power Cord Adapter
(1)
to the positive and
negative battery terminals of the Warrior machine.
3. Disconnect the power cable of the lift actuator from the
machine, and connect the Power Cord Adapter into the
cable leading to the lift actuator motor.
4. Press the For/Rev switch on the Adapter
(1)
to lower the lift actuator until the scrub deck is resting on the floor
in a neutral position (no tension/pressure on the actuator).
5. Remove the retaining key
(2)
and link pin
(3)
that
secures the spring housing
(4)
to the scrub deck to permit
the actuator to swing freely.
6.
While holding the spring housing
(4)
from turning, press
the For/Rev switch on the Adapter
(1)
to raise the spring
housing
(4)
toward the actuator gear housing
(5)
until
the motor stops (minimum limit switch engaged).
7.
Rotate the spring housing
(4)
until the distance between
the spring housing and gear housing
(5)
is within the
Upper Limit range listed in the table below.
• The “Old Style” spring housing
(4)
is identifiable as a
one-piece housing.
• The “New Style” spring housing
(4)
is identifiable as
split down the center.

8. Hold the spring housing from rotating, and press the For/Rev button of the Adapter
(1)
to lower the actuator to
its lowest position until the motor stops (maximum limit switch engaged).
9. Measure the Housing Distance as described above, but for the Lower Limit position, and compare this to the
values shown in the table. If necessary, adjust the lower limit as described below.
