How to Remove the Jib Boom Lift
Cylinder
Note: Perform this procedure with the boom in the
stowed position.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
1
Raise the jib boom slightly and place blocks
under the platform mounting weldment. Lower
the jib 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.
2
Tag, disconnect and plug the jib boom lift
cylinder hydraulic hoses. Cap the fittings on
the cylinder.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
3
Support the rod end of the jib boom lift cylinder
with a suitable lifting device.
