SCISSOR COMPONENTS
32 Disconnect and plug the hydraulic hose on the
lift cylinder. Cap the fitting 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.
33 Tag and disconnect the wires from the solenoid
valve on the cylinder.
34 Attach the strap from the crane to the lug on
the rod end of the cylinder.
35 Remove the external snap ring from the
cylinder barrel-end pin (index #17). Use a soft
metal drift to remove the pin. Remove the
cylinder from the machine.
Crushing hazard. If the overhead
crane is not properly attached, the
cylinder may become unbalanced
and fall when it is removed from
the machine.
Component damage hazard. Be
careful not to damage the valve or
fittings on the cylinder while
removing it from the machine.
36 Place a 4 x 4 x 32 inch (10 x 10 x 81 cm) long
block across both sides of the chassis under
the number 1 center pivot pin (index number
#9).
37 Attach the strap from the crane to the number 1
inner arm (index #10). Raise the inner arm
slightly and remove the safety arm. Lower the
arms on to the block.
Bodily injury hazard. Keep hands
clear of moving parts when
lowering the arms onto the block.
38 Remove the cables from the number 1 inner
arm (index #10) and lay off to the side.
Component damage hazard.
Cables can be damaged if they
are kinked or pinched.

arm (index #17). Do not lift it.
40 Remove the pin retaining fasteners from the
number 1 center pivot pin (index #9) at the
ground controls side.
41 Remove the external snap ring. Use a slide
hammer to remove the pin.
42 Repeat steps 40 and 41 for the battery pack
side.
Bodily injury hazard. The number
1 outer arm (index #17) may
become unbalanced and fall if not
properly supported when the pins
are removed.
43 Slide the arm to the non-steer end and remove
the outer base scissor arm from the machine.
Note the position of the wear pads
before the arm is removed so
when the scissor is assembled
they will be in the correct position.
