How to Remove the Jib Boom
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 Remove the platform.
2 Disconnect the electrical connector from the

connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
