7. If the belt is not seated
properly in the pulley grooves,
gently push or pull in the
direction that the belt must
move while rotating the belt.
8. Reinstall the Belt Guard and
Side Skirt Assembly, then test
the scrub system for correct
operation.
Lift Actuator Adjustment
The lift actuator adjustment makes sure that the deck can be properly positioned when extended for
scrubbing operations and when retracted for machine transport. The adjustment sets the position of the
drive nut on the actuator lead screw when either of the internal travel limit switches open in order to stop
the motor rotation. The retracted position is set by running the motor in the retracted position until the
motor stops and then screwing the drive nut onto the lead screw until it is in the correct location. Once the
retracted position is established, the extended position is set by adjusting an internal cam under the rubber
cover of the actuator motor .
Using the Actuator Power Cord Adapter
The adjacent drawing shows the special
actuator power cord adapter (p/n 56407502)
that is needed to connect the machine’s
battery pack and actuator motor for setting
the actuator drive nut limit settings. To
connect the actuator power cord adapter:
1. Open the machine battery compartment
and disconnect the battery connector. The
battery pack is needed to power the scrub
deck actuator motor to correctly set the IN
and OUT limit switches.
2. Connect the actuator motor to be tested to
the power cord adapter end.
3. Connect the alligator clips from the cord adapter (red clip to the positive and black to negative) to
battery connector or battery posts. Use the rocker switch on the actuator power cord adapter to change
the motor rotation when setting the correct actuator drive nut dimensions.
Service Note:
You can also use the above actuator power cord adapter to help position the drive
nut/spring housing assembly (in or out) for ease in actuator motor installations.
