Check the Boom Wear Pads

Maintaining the boom wear pads in good condition
is essential to safe machine operation. Wear pads
are placed on boom tube surfaces to provide a low
friction, replaceable wear pad between moving
parts. Improperly shimmed wear pads or continued
use of extremely worn wear pads may result in
component damage and unsafe operating
conditions.
If the wear pads are still within
specification, see Repair
Procedure 4-2, How to Shim
the Boom.
1 Start the engine from the ground controls.
2 Raise the end of the boom to a comfortable
working height (chest high), then extend the
boom 1 foot (30 cm).
3 Measure each wear pad. Replace the wear pad
if it is less than specification. If the wear pad is
still within specification, shim as necessary to
obtain zero clearance and zero drag.
4 Extend and retract the boom through the entire
range of motion to check for tight spots that
may cause binding or scraping of the boom.
Always maintain squareness
between the outer and inner
boom tubes.

Check the Free-wheel
Configuration
Proper use of the free-wheel configuration is
essential to safe machine operation. The
free-wheel configuration is used primarily for
towing. A machine configured to free-wheel without
operator knowledge may cause death or serious
injury and property damage.
Collision hazard. Select a work
site that is firm and level.
Component damage hazard. If the
machine must be towed, do not
exceed 2 mph (3.2 km/h).
Non-steering wheels: All models
1 Chock the steer wheels to prevent the machine
from rolling.
2 Center a lifting jack of ample capacity
(20,000 lbs/9072 kg) under the drive chassis
between the non-steer wheels.
3 Lift the wheels off the ground and then place
blocks under the drive chassis for support.
4 Disengage the drive hubs by turning over the
drive hub disconnect caps on each
non-steering wheel hub.
