34 - Scrub System, Cylindrical
Deck Lift Actuator
Getting Neutral Weight on the Deck
In order to remove the deck actuator pivot pins, you will need to take the weight off the deck To do this, you
either need to lower the deck to the floor, but stopping before the actuator applies normal scrub pressure; or
support the deck in its raised position
•
The easiest way to do this is with the actuator test cable described on
be moved in small increments, as needed
•
If you don’t have an actuator test cable, the next best method is to lower the deck normally, press the
E-Stop button, disconnect the battery, and then slightly jack the front of the machine just enough to take
the pressure off the deck
•
If the deck actuator cannot be powered, or cannot be operated for any reason, then the best solution is to
support the deck as described below:
a
Using a floor jack or similar method, raise the front of the machine slightly.
b Apply blocking, cribbing, or a wheeled dolly (if necessary) below the scrub deck
c Slowly lower the front of the machine until the weight on the retaining pins
(E or F)
becomes
neutral, and the pins are free to move
Note:
For simplicity, the procedure is written for using the actuator test cable.
CAUTION:
Risk of arc flash. Make sure to disconnect the main battery connector when working
below the floor panel.
