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 oor, 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 page 94. This permits the deck to

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 oor 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 ash. Make sure to disconnect the main battery connector when working

below the oor panel.

1. If you don’t have an actuator test cable, take the

weight off the deck as described above. Otherwise,

do this at step 6 below

2. Disconnect the main battery cable below the

operator’s seat.

3. Remove the Floor Panel described on page 71.

4. Remove the screw (A) that secures the actuator

access cover (B) to the side of the battery bay, and

lift the cover out toward the right to remove it.

5. Disconnect the electrical connector (C) from

the actuator.

6. Connect the actuator cable to the test cable

as described on page 94, and lower the

deck to a neutral weight position.

7. Remove the retaining clip (D) and pin (E)

from the top of the actuator.
