Boom
a. Component/Assembly Verification
The inner (15) to intermediate (16) boom separation
should be checked when assembling new boom sections
or chains, or when the rear retract chain clevis has been
moved forward on the anchor plate.
Measure the separation between the inner and
intermediate boom top plates (17). The distance should
be at least 8.5" (216 mm) and not greater than
11" (279 mm) with the boom fully retracted and the
chains properly tensioned. A distance of less than
8.5" (216 mm) could result in interference and cause
damage to boom components.
If the distance is less than 8.5" (216 mm) or greater than
11" (279 mm):
1. Verify that the retract chain clevis (3) is not mounted
in the last hole (7) in the anchor plate (8).
2. Make sure that the chain system is properly
tensioned. Refer to Section 3.4.3, “Boom Chain
Tension Check,” and Section 3.4.4, “Boom Chain
Tension Adjustment.”
