ACTUATOR DRIVE NUT ADJUSTMENT
This manual section explains the steps for adjusting the drive nut (housing assembly) setting for the machine’s two adjustable actuator motors.
Reference the chart below to find the IN & OUT dimensional specification for the specific actuator motor needing adjustment.
Part #
Actuator Motor
Drive Nut IN position
Drive Nut OUT position

Scrub Brush Lift
non-adjustable (preset)
non-adjustable (preset)

Squeegee Lift
1” (25mm)*
4-1/4” (108mm)*
56303119
Side Broom Lift
6-7/8” (175mm)*
9-9/16” (243mm)*
*The “Drive Nut Housing Assy IN/OUT Position” dimensions are measured when completely assembled. Reference points are the gear box step
to the edge of the Steel Tube (A) as shown in Figure 3, or the edge of the plastic Spring Housing Assembly as shown in Figure 4.
General Instructions for All Actuator Motors
1
See Figure 2. This shows the special actuator
power cord adapter
(PN 56407502)
that is needed
to connect the machine’s battery pack and actuator
motor for setting the drive nut limit settings.
2
Open the machine battery compartment and
disconnect the battery connector. The battery pack
is needed to power the lift actuator motor to properly
set the IN & OUT limit switches.
3
Connect the actuator motor to be tested to the power
cord adapter end. Then connect the alligator clips
from the cord adapter (red clip to the positive and
black to negative) to battery connector or battery
posts. The rocker switch is used to change the motor
rotation in setting the correct drive nut dimension.
Instructions for Squeegee and Side Broom Lift Actuator Drive Nut Adjustment
1
See Figure 3. Hold onto the Actuator Drive Nut
(A)
and press the rocker switch to run the drive motor and retract the nut towards the motor
housing (it’s IN limit).
2
Measure the position of the drive nut on the actuator shaft. Manually turn the steel tube to the IN position as shown in the chart.
3
Hold the drive nut then press the adapter cord rocker switch to run the drive motor to the OUT position (wait until the motor stops).
4
Measure the position of the drive nut on the shaft and compare the measurement with the OUT position shown in the chart.
5
When the measurement doesn’t match the dimension shown in the chart it is necessary to remove the Adjuster Cover
(B)
and adjust the Out
position.
6
To increase the travel of the drive nut, turn the adjuster clockwise. To decrease the travel of the nut, turn the adjuster counter clockwise.
NOTE: Use a 1/2” (13 mm) socket to turn the adjuster. Each click of the adjuster will change the nut travel 1/16 inch (1.6 mm).
7
After each adjustment, hold the drive nut, run the actuator IN & OUT and check both dimensions. After checking that the drive nut limits are
set correctly then replace the adjuster cover.
Service Tip Note:
Use the above power cord adapter to help position the drive nut (in or out) for
ease in actuator motor installations.
