Boom
24. Start the engine and extend the boom until the inner
boom retract chain adjustment nut (23) on the
bottom of the primary intermediate boom is visible.
Shut the engine OFF.
25. Loosen the elastic locknut (23) on the inner boom
retract chain clevis. DO NOT remove the elastic
locknut at this time, but loosen the nut as far as
possible to gain as much slack as possible in the
retract chain.
26. Return to the operator’s cab, start the engine and
slowly retract the boom all the way back and then
extend the boom approximately 1" (25 mm) or just
until all the tension on the inner boom retract chain is
relieved. Shut the engine OFF.
27. At the rear of the boom, locate the two retract chain
anchor plates (24) holding the inner boom retract
chain (25) to the inner boom, just in front of the hose
reel assembly (26). Remove the elastic locknut (27)
and shoulder bolt (28) holding the inner boom retract
chain clevis to the anchor plates. Discard the elastic
locknut and save the shoulder bolt. The two anchor
plates can remain in place on the inner boom.
28. Remove the two capscrews (29) and
lockwashers (30) holding the hose carrier
support (31) and the lower wear pad to the
secondary intermediate boom.
29. Pull the hose carrier support with the hose carrier
attached toward the rear of the boom. Reinstall the
capscrews (29) and lockwashers (30) back through
the holes in the bottom of the secondary
intermediate boom to hold the wear pad in place. DO
NOT fully tighten the capscrews.
