Platform Removal
Machine Stabilization:
The arm stack can be supported by using an overhead
crane, Figure 4-31. If an overhead crane is not available
the stack may also be lifted by using a forktruck using the
following instructions:
1. With the forks on the forktruck slid close together,
enter from the front of the machine and place the
forks on the cross tube of the second arm weldment
below the platform.
2. Slowly lift the arm stack with the forktruck while the
manual descent valve is being engaged (this allows
the oil to drain back into the tank).
3. Place machine on safety prop and leave the fork-
truck in place.
If removal of the platform becomes necessary use the
above procedure to stabilize the platform for pin and plat-
form removal.
NOTE: Procedures apply to both left and right sides.
Removal:
1. Disconnect all wiring and hydraulic lines attached to
the platform or platform components. Cap hydraulic
lines to prevent leakage.
2. Support the platform along the sides with the fork-
truck forks or use suitable straps or chains at the
four corners of the platform.
3. Remove the two Bolts (2) and Lockwashers (3)
attaching the two Platform Pivot Pins (1) to the Plat-
form.
4. Continue on to the rear of the machine. (See next
