c.
Measure the chain sag. Acceptable boom
chain sag is between 1-1/2" (38,1 mm) and
2-1/2" (63,5 mm). If the chain sag is less
than 1-1/2" (38,1 mm), repeat Steps “a”
through “c.”
3.
If the distance measured in Step 1 is less than 2"
(50,8 mm) (but greater than 1-1/2") (44,5 mm):
a.
Remove the rear cover from the outer boom
and adjust the top extend boom chains.
b.
Tighten the locknuts (Figure 59) for each
chain. Be sure each locknut is tightened
equally so that each chain maintains the
same tension. Equal chain tension can be
checked by the position of the yoke on the
outer boom (Figure 60). The front of the yoke
should be parallel with the front edge of the
boom.
c.
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).
