B. Top Boom Chain Tension Adjustment
(As Required)
1. Retract the boom completely to check the position
of the inner boom. The inner boom section
should extend between 1-1/2" (38,1 mm) to 2-1/2"
(63,5 mm) beyond the end of the intermediate
boom section (Figure 58). If the measurement is
not between 1-1/2" (38,1 mm) and 2-1/2" (63,5
mm), the boom may require more extensive
adjustment and/or repair. Contact your autho-
rized JLG distributor.
2. If the distance measured in Step 1 is 2" (50,8
mm) or more but less than 2-1/2" (63,5 mm):
a. Tighten the locknut (Figure 57) located on the
bottom of the outer boom.
b. Cycle the boom in and out. Then, with the boom
horizontal (level), fully extend the boom and
retract 2" (50,8 mm) (one inch per section).
