ARM ASSEMBLY
The arm stack can be supported by using an overhead
crane,(See Figure 3-47.). If an overhead crane is not
available the stack may also be lifted by using a fork-
truck 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 weld-
ment 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.
4. At this point the lift cylinder removal may begin.
(Refer to Section 4.6, Lift Cylinder Removal)
If removal of the platform becomes necessary use the
above procedure to stabilize the platform for pin and
platform removal.
