TOWER COMPONENTS
5 Attach a suitable lifting device to the cable
track. Carefully remove the cable track from the
tower and rest it on top of the cabinet.
Component damage hazard.
Cables and hoses can become
damaged if they are kinked or
pinched.
6 Place a block under the tower lift cylinder for
support.
7 Remove the pin retaining fasteners from the
tower lift cylinder rod-end pivot pin.
8 Use a soft metal drift to remove the pin. Rest
the tower lift cylinder on the block.
9 Tag, disconnect and plug the tower extension
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.
10 Position the forks from a forklift into the forklift
pockets located under the tower. Secure the
tower to the forks.
11 Remove the transport lock pin from the tower
near the tower rest pad.
12 Remove the pin retaining fasteners from the
tower pivot pin at the tower rotation riser.
13 Use a soft metal drift to remove the tower pivot
pin. Carefully remove the tower assembly from
the machine and place it on a structure capable
of supporting it.
Crushing hazard. The tower
assembly could become
unbalanced and fall when removed
from the machine if not properly
supported and secured to the
forklift.
How to Disassemble the Tower
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. Refer to Section 2,
Hydraulic Hose and
Fitting Torque Specifications.

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 Attach a suitable lifting device to the light bar
cylinder.
4 Remove the pin retaining fasteners from the light
bar link pivot pin. Use a soft metal drift to
remove the pin. Remove the cylinder from the
tower assembly with links and levers attached.
Note: There is a spacer tube between the two links
that may fall out when the pivot pin is removed.
