as shown in Figures 3 and 4.

General Instructions for All Actuator Motors

See Figure 2.

This 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 drive nut limit settings.
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 and OUT limit switches.
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 Scrub Brush Lift Actuator Drive Nut Adjustment

See Figures 3 and 4.

On a new scrub lift actuator motor remove (spin-off) the Drive Nut

(B)

and

rst slide on the Spring Housing Guide

(A)

, then install the short

compression Spring

(C)

onto the actuator (lead screw) shaft. Next reinstall the plastic Drive Nut

(B)

as shown (with the nut pin pocket away from the motor).

Then

nish assembly of remaining parts (long compression spring, Spring Housing

(D)

and mounting hardware).

Hold onto the spring housing assembly and press the rocker switch to run the drive motor and retract the spring housing toward the motor housing (its IN limit).

Measure the position of the spring housing assembly on the actuator shaft. Manually turn the spring housing assembly to the appropriate IN position shown in

the chart above.
Hold the spring housing assembly, then press the adapter cord rocker switch to run the drive motor to the OUT position (wait until the motor stops).

Measure the position of the spring housing assembly on the shaft and compare the measurement with the OUT position shown in the chart.

When the measurement doesn’t match the dimension shown in the chart it is necessary to remove the Adjuster Cover

(E)

and adjust the OUT position.

To increase the travel of the spring housing assembly, turn the adjuster clockwise. To decrease the travel of the assembly, turn the adjuster counter clockwise.

FIGURE 2

FIGURE 3

Note: Use a 1/2” (13 mm) socket to turn the adjuster.

Each click of the adjuster will change the spring housing
assembly travel 1/16 inch (1.6 mm).
After each adjustment, hold the spring housing assembly,

run the actuator IN and OUT and check both dimensions.
After checking that the spring housing limits are set
correctly replace the adjuster cover. Service Tip Note: Use
the above power cord adapter to help position the spring
housing assembly (in or out) for ease in actuator motor
installations.
After adjusting the actuator spring housing dimensions,

10.

follow the

Scrub Brush Lift Actuator Removal

(Disc

Cylindrical)

manual section to reassemble.

Service Tip: See Figure 4.

Note the correct orientation of

the Spring Housing

(D)

when installing the complete motor

assembly and also run the spring housing assembly to the IN
(retracted) position for machine installation.
