Boom Section 5 – Procedures
5.4-5 Boom Section Wear Pad
Replacement
If wear pads inside the boom sections are worn and
cannot be shimmed to meet the specification, they
must be replaced. Wear pads that are worn past the
specification can impair machine operation. For wear
pad limit specification, refer 5.4-1 Check Wear Pads.
WARNING
Use original or manufacturer-approved parts and
components for the MEWP.
The boom sections must be disassembled to replace
the wear pads. Typically the bottom platform-end
and the top counterweight-end pads on each boom
section wear out first. Check which ones need to be
replaced before disassembly.
NOTE
To disassemble the boom sections, the extension
cylinder inside the boom must be removed first.
See 5.4-13 Extension Cylinder Removal.
To disassemble the boom sections, the fly boom and
mid boom must be slid fully out of the main boom.
Provide enough space at the platform end of the
machine at least the length of boom assembly.
Preparation:
â–ª
Remove the jib boom and the platform before
disassembly. Removing these components limits
twisting when lifting, and provides better control
when sliding the boom sections out. See 5.4-6
Platform and Jib Boom Removal.
â–ª
Before beginning, place the machine in the
proper shut down position, parked on level
ground.
â–ª
Make sure the e-stops are pushed in and the key
is off.
â–ª
Turn the main power disconnect switch off. Lock
out the switch.
CAUTION
There is a risk of personal injury or equipment
damage if repositioning the boom during this
procedure. Use the base controls with auxiliary
power (engine off) to reposition safely.
IMPORTANT
If boom repositioning is necessary during this
procedure, select the emergency power position
from the start/function enable/emergency power
switch, then activate the desired boom function.
To avoid overloading the 12-volt auxiliary pump
motor when operating on auxiliary power, do not
operate more than one function at a time.
CAUTION
THere is a risk of personal injury or equipment
damage. Always use suitable lifting equipment
and safe rigging practices when performing the
following procedures.
NOTE
If boom repositioning is required with the platform
removed and control cables disconnected,
reconnect the two main (24 pin) control cables
and the jib and platform rotate harness (as
equipped) to the platform control box. See 5.4-12
Platform Control Console Connection.
The machine cannot operate with the two
platform control harnesses disconnected.
