Boom Installation
Inspect Boom Stops
See Figure 4-41 for the following procedure.
Jib stops (2) are shipped in the assembled position on boom
butt (1) as shown in View A.
Before installing the boom butt, inspect both jib stops for
proper operation, as follows:
1. Fully raise and lower boom stop (2) by hand.
2. While performing step 1, strut (3) should extend and
retract fully without binding.
3. Repeat steps 1 and 2 several times to make sure strut
(3) operates freely without binding.
4. OPERATOR, observe jib stops during operation:
When the boom is raised to approximately 77°, boom
stop pins (4) should bottom out in saddles (5).
Stop operating immediately if boom stop pins do not
engage saddles as boom is raised. Lower boom to
ground and take corrective action.
WARNING
Crushing Injury Hazard!
Never work under or inside boom sections that are not
securely blocked.
WARNING
Falling Load Hazard!
Jib backstay straps can be stored on boom sections for
shipping.
If jib will not be used, remove all jib backstay straps, links,
and pins stored on boom sections.
