B. Top Boom Chain Tension Adjustment
(As required)
NOTE: Always perform the “Boom Chain Tension Check” starting on
page 152 before adjusting the boom chain tension.
1. Park the vehicle on level ground. Place the travel select lever in (N)
NEUTRAL, move neutral lock lever to NEUTRAL LOCK position,
engage the parking brake switch and raise the boom to a horizontal
position. Retract the boom completely and turn the vehicle OFF.
2. Adjust the top extend boom chains (1) by tightening the locknuts (3)
located at the rear of the boom. Be sure each locknut is tightened
equally so that each chain maintains the same tension.
3. Equal chain tension can be checked by the position of the yoke (2)
on the outer boom. The front of the yoke should be parallel with the
front edge of the boom.
