nut and run it out enough so that the Pin Bracket
(F)
can be turned in to make up difference
from the dimension targeted. Example: the
fi
rst IN dimension measures 4-1/2” minus the
4-1/8 target dimension the difference is 3/8”. Turn in nut manually 3/8”and then run the
housing in under power until the inner limit stops the motor. Readjust until dimension shown
is achieved.
4
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).
5
Measure the position of the spring housing assembly on the shaft and compare the
measurement with the OUT position shown in the chart.
6
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.
7
To increase the travel of the spring housing assembly, turn the adjuster clockwise. To
decrease the travel of the assembly, turn the adjuster counterclockwise.
NOTE: Use a 1/2” (13mm) socket to turn the adjuster. Each click of the adjuster will
change the spring housing assembly travel 1/16 inch (1.6mm).
8
After each adjustment, hold the spring housing assembly, run the actuator
IN & 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.
9
After adjusting the actuator spring housing dimensions,
follow the
Scrub Brush Lift Actuator Removal
(Disc
or
Cylindrical)
manual section to reassemble. Reference
Figure 8.5
to correctly mount the top of lift motor to
the chassis by model size.
Service Tip:
See
Figure 8.5.
Note the correct orientation
of the Spring Housing
(E)
when installing the complete
motor assembly and also run the spring housing assembly
to the IN (retracted) position for machine installation.
1
See
Figure 8.5 and 8.6
. On a new scrub lift
actuator motor remove (spin-off) the Drive
Nut
(C)
and install the short compression
Spring
(D)
onto the actuator (lead screw)
shaft. Next reinstall the plastic Drive Nut
(C)
as shown (with the nut pin pocket away
from the motor). Then
fi
nish assembly
of remaining parts (long compression
spring, Spring Housing
(E)
and mounting
hardware).
2
Hold onto the spring housing assembly and
press the rocker switch to run the drive motor
and retract the spring housing towards the
motor housing (its IN limit).
3
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
on previous page.
Additional adjustment
instructions:
The inner top spring is set at
a pre-loaded compressed setting. It will be
necessary to slightly over-ride the manual
adjustment after running the drive nut in
and turning it by hand. A small problem is
observed in the retracted position as the pin
mounting bracket interferes with the motor.
After making the initial adjustment hold the
