Raising:
Position jib stop to clear jib butt. Luff up jib strut until straps
on inserts are clear of strap supports. Slowly raise boom
while jib point rollers are allowed to roll on ground. Tension
should be applied to luffing jib hoist to keep jib straps above
strap supports. Boom up until boom to luffing jib angle
reaches 145 degrees. Lower jib stops to operating position.
Continue to boom up until boom to luffing jib reaches value
specified in table. Tighten luffing jib suspension with luffing
jib hoist. Boom and luffing jib are then raised together using
boom hoist until boom reaches desired boom operating
angle. Luffing jib radius must be within capacity chart before
swinging over side of machine when raising over end of
blocked crawlers.
Lowering:
Position boom at 85 degrees prior to lowering luffing jib.
Lower luffing jib until boom to luffing jib angle reaches value
specified in table. Lower boom until luffing jib point rollers
contact ground. Continue to lower boom while luffing jib
rollers roll along ground until boom to luffing jib angle
reaches 145 degrees. Position jib stop to clear jib butt.
Keep enough tension on luffing jib hoist to keep jib straps
above strap supports. Continue to lower boom while luffing
jib rollers roll along ground.
Caution: Do not, under any condition, allow boom to luffing
jib angle to become less than 70 degrees.
