Hydraulic Cylinder Removal

1)

Deploy platform using control pendant ( /OUT).

2)

Raise platform to a comfortable working height and then support.

WARNING!

THE SERVICE ACCESS PANEL IS HINGED ALONG THE REAR EDGE AND SHOULD
BE HELD UP WHILE REMOVING THE RETAINING SCREWS AT THE FRONT EDGE.
THIS WILL PREVENT PANEL FROM FALLING AND CAUSING INJURY OR DAMAGE

3)

To gain access to underside of lift, hold service access panel up, remove two retaining
screws and lock-nuts from front edge of panel, and lower panel.

WARNING!

•• WEAR PROTECTIVE CLOTHING AND EYE PROTECTION AT ALL TIMES. BAT-

TERIES CONTAIN ACID THAT CAN BURN. IF ACID COMES INTO CONTACT
WITH SKIN, IMMEDIATELY FLUSH AFFECTED AREA WITH WATER AND WASH
WITH SOAP.

•• WORK IN A PROPERLY VENTILATED AREA. DO NOT SMOKE OR USE AN OPEN

FLAME IN THE VICINITY OF BATTERY.

•• DO NOT LAY ANYTHING METALLIC ON TOP OF BATTERY.

4)

Disconnect positive battery cable at vehicle battery compartment.

WARNING!

OPENING THE HYDRAULIC PUMP MANUAL RELEASE VALVE WILL ALLOW THE
LIFT PLATFORM TO LOWER. STAND CLEAR AND CHECK OF OBSTRUCTIONS TO
PREVENT INJURY OR DAMAGE.

5)

Open hydraulic pump manual release valve and leave open.

6)

Refer to Figure 4-24.

Unfasten trunnion keeper-plates from lifting frame, and remove

keeper-plates from trunnion. Remove bushings from trunnion.

NOTE:

The following step will spill hydraulic fluid; have dry rags on hand.

7)

Disconnect hydraulic hose from quick-disconnect fitting; this could require removing hose
retaining clamp.

8)

Disconnect electrical harness from cylinder. Protect exposed connectors on harness and
cylinder.

9)

Remove pivot fitting from right-side of cylinder.
