Manual Addendum — Boom Tip Retaining Plates
Section 4 — Preventive Maintenance and Inspection

Pins and Pin Retainers
Boom Tip Pin Retaining Plates
Both ends of the boom tip pin are secured by a retaining
plate and two cap screws. When inspecting the boom
tip pin, make sure the cap screws installed through the
retaining plate are secure.

Removal

1. Position the unit on a level surface, apply
the parking brake, and chock the wheels.

2. Release the pressure from each circuit in
the hydraulic system by shifting the lower control handle for each function in both
directions several times. Also, shift the
control handles at the platform for the upper tool circuit functions in both directions
several times.
3. Remove the covers at the platform.

Figure 4.XX — Retaining Plate and Cap Screws
Check the retaining plate cap screws to be sure they are
torqued to 32 foot-pounds (43 N•m) or 90 percent of the
normal installation torque of 35 foot-pounds (47 N•m)
as recommended by the Preventive Maintenance and
Inspection Checklist.

Section 6 — Mechanical Systems

Platform and Leveling System
CAUTION

Injury and property damage can result
from unexpected platform movement. Tilt
the platform to a nearly level position before moving the platform leveling control
to Auto.
Injury and property damage can result
from unexpected platform movement. Allow room for platform movement when the
leveling control is moved to Auto.
NOTICE

Damage to the unit can result if hoses are not
connected properly. Mark the platform leveling hoses before they are disconnected.

4. Support the platform so that it may be removed after it is disconnected from the
boom tip.
5. Remove the access covers near the boom
tip.
6. Disconnect the hoses from the leveling
system.
7. Disconnect the hoses and air lines that are
routed from the boom tip to the platform
assembly.
8. Remove the jib/winch assembly cover.
9. Disconnect the hoses that are connected to
the jib/winch assembly.
10. Remove and discard the cap screws that
secure the retaining plate on the end of the
boom tip pin on the platform side (refer to
Figure 6.XX). When servicing the boom tip
pin or retaining plates, do not reuse the retaining plate cap screws. Once a cap screw
is removed, the nylon patch on the threads
will be distorted. This distortion may not
allow the cap screw to tighten properly if
reused. Use new cap screws of the proper
length with nylon patch when reinstalling
the retaining plate.

11. While supporting the platform, slide the
platform pivot arm, mounting bracket, platform, and all of the components connected
to them off the shaft.
12. Disconnect and remove the jib tilt cylinder.
13. Remove and discard the cap screws that secure the retaining plate on the end of the jib/
winch side of the boom tip pin (refer to Figure 6.XX).
14. Support and remove the jib/winch assembly.
15. Remove the cap screws that secure the leveling system to the end of the fiberglass.
16. Support and remove the leveling system
from the end of the fiberglass.
Installation

1. Insert the leveling system into the end of the
fiberglass and secure it with the cap screws,
washers, and self-locking nuts. Torque the
cap screws to 75 foot-pounds (95 N•m).
2. Install the jib/winch assembly on the boom
tip pin with the shims, retaining plate, and
new cap screws. Torque the cap screws to 35
foot-pounds (47 N•m).
3. Install the jib tilt cylinder.
4. Install the platform assembly on the boom
tip pin with the shims, retaining plate, and
new cap screws. Torque the cap screws to 35
foot-pounds (47 N•m).
5. Connect the hoses and air lines to the jib/
winch assembly, platform assembly, and the
leveling system.

6. If any fluid leaked from the leveling
valve, measure the fluid for the proper
level (refer to Section 5 under leveling
valve) and add if necessary.
7. Replace the covers.
8. Move the platform leveling control to
Manual. Operate the tilt control and
check for proper operation.
9. Carefully move the leveling control to

checking for leaks and proper operation.
12. Perform a structural test as described in
Section 9.
