Squeegee System 73Service Manual – Focus II / Scrubtec R6 Rider Autoscrubber
Actuator Limit Adjustment
To protect the actuator from traveling too far, it
contains an internal limit switch for maximum travel.
This adjustment requires the use of the Actuator
Power Cord Adapter (99) (PN 56407502) shown to the
right.
This procedure is typically performed as part of
replacing the actuator. If the actuator is not already
removed from the machine, then remove it following
the procedure on page 76.
1. Connect the Power Cord Adapter (99) to the
positive and negative battery terminals of the
Focus II machine. Make sure the adapter is connected so that it receives the full 24 volts.
2. Connect the other end of Power Cord Adapter (99) to the actuator’s power connector.
3. While holding the nut housing (18) from turning, press the For/Rev switch on the Adapter (99) to move
the nut housing (18) toward the actuator gear housing (17A) until the motor stops (minimum limit
switch engaged).
4. Rotate the nut housing (18) until the distance between the spring housing and gear housing (Housing
Distance) is 5/16", and as necessary, unscrew the nut just enough to make the clevis pin holes (18A)
parallel to the gear housing (a drill bit is shown in the photo for clarity).
Important: After the limit is adjusted and
until the actuator is back in the machine,
make sure not to rotate the nut housing
relative to the motor housing.
5. While holding the nut housing (18) from
turning, press the For/Rev switch on the
Adapter (99) to move the nut housing
away the actuator gear housing until
the motor stops (maximum limit switch
engaged).
6. Measure the Housing Distance. If it is not approximately 4",
then adjust the lower limit.
a. Remove the dust cap (17B) from the top of the gear housing
using your ngers or a small screw driver.
b. Place a 1/2" socket over the limit adjustment nut to turn the
nut, and increase or decrease the lower limit as follows:
Important: Even though the center of the adjustment nut looks
like it will accept a screwdriver blade, this is the retainer for
the adjustment nut. Do Not try to turn the retainer!
• Each “click” of the adjuster nut changes the Housing
Distance by 1/16".
• To increase the Housing Distance, turn the nut clockwise.
• To decrease the Housing Distance, turn the nut
counterclockwise.
7. Using the Adapter cord (99), move the nut housing back to the approximate position it was in when you
removed it from the machine, and reinstall the actuator on the machine.
