Platform Leveling Slave Cylinder

The slave cylinder and the rotator pivot are the
two primary supports for the platform. The slave
cylinder keeps the platform level through the
entire range of boom motion. It operates in a
closed-circuit hydraulic loop with the master
cylinder. The slave cylinder is equipped with
counterbalance valves to prevent movement in
the event of a hydraulic line failure.
How to Remove the Platform
Leveling Slave Cylinder
Note: Before cylinder removal is considered, bleed
the slave cylinder to be sure there is no air in the
closed loop.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or the
hose end must be replaced. All connections must
be torqued to specification during installation. Refer
to Section 2, Hydraulic Hose and Fitting Torque
Specifications .
1 Extend the boom until the slave cylinder barrel-
end pivot pin is accessible.
2 Raise the boom slightly and place blocks under
the platform for support.
3 Lower the boom until the platform is resting on
the blocks just enough to support the platform.
Note: Do not rest the entire weight of the boom on
the blocks.
