Extension Cylinders
The primary boom extension cylinder is located
inside the boom assembly and incorporates cables
and pulleys that are responsible for extending
the number 2 and 3 boom tubes. The secondary
boom extension cylinder (S-120HD models) is
located underneath the number 0 boom tube and
is responsible for extending the number 1 boom
tube. The extension cylinders are equipped with
counterbalance valves to prevent movement in the
event of a hydraulic line failure.
How to Remove the Primary
Boom Extension Cylinder
Bodily injury hazard. This
procedure requires specific repair
skills, lifting equipment and a

and tools could result in death
or serious injury and significant
component damage. Dealer
service is strongly recommended.
Note: When removing a hose assembly or fitting,
the O-ring on the fitting and/or hose end must be
replaced and then torqued to specification during
installation.
