A. Boom Chain Tension Check
Figure 2–71. Every 1,000 hours of engine operation, check
both boom chains for proper tension.
1. Park the vehicle on level ground. Place the travel
select lever in NEUTRAL (N), engage the parking
brake switch and raise the boom to a horizontal
boom. Retract the boom completely and shut the
engine off.
2. Measure the distance between the inner boom and
the intermediate boom (Fig. 2–72). The inner boom
should extend 2.25 inches (57 mm) to 2.75 inches
(70 mm) beyond the end of the intermediate boom. If
the measurement is less than 2.25 inches (57 mm),
the chains require adjustment.
