SIDE FOLDING-SWING AROUND JIB
OPERATION
Deployment Procedure
1. Using boom telescope function, fully retract boom.
2. Using lift function, lower boom to allow for easier access
to jib deployment pins C1 and C2.
NOTE: When lowering the boom below horizontal, two
persons may be required. With the telescope
control in neutral, the boom can creep out when
below horizontal.
3. Install pins C1 in upper and lower jib ears. Install retainer
spring clips. These pins will be used as a pivot point to
swing jib into the deployed position.
4. Locate the stowed position of pins C2. If the pins are in
jib attachment holes or boom sheave case jib holes,
remove pins from storage location.
5. Remove jib swing Pin B from top ear of jib.
6. Remove stow Pin A from ramp/side stow bracket
assembly on jib and stow in Stow Loop D and install
spring clip.
7. Attach tag line to sheave case end of jib.
8. Using lift function, raise boom to a horizontal position.
9. Using telescope function, slowly extend boom
approximately one foot. This procedure will pull the jib
out of the stow bracket.
10. Using tag line, swing jib into deployed position.
11. Remove cable keeper pins from boom sheave case and
jib. Remove hook block. Pivot jib slightly to allow for
loadline to be removed from boom sheave case.
Remove loadline from boom sheave case and place in
an area to minimize possible damage.
12. Pivot jib into place, visually aligning the upper C2 pin
holes. Install upper C2 pin and spring clip. A slight
hammer strike may be necessary to install pins. Always
use proper eye protection during this step.
13. Using jib jack, (Refer to Jib Jack Procedures in this
chapter) position jib so that lower C2 pin holes are in
alignment and install lower C2 pin and spring clip.
14. Using hoist function, un-spool enough loadline to reeve
loadline over jib sheave case. Keep slight tension on
loadline to avoid bird caging of loadline on hoist drum.
15. Route loadline over jib sheave and install keeper. Install
line block to end of loadline.
16. Remove anti-two-block weight/chain assembly from
boom tip switch and install on jib tip switch. Be certain to
use keeper provided with switch.

cord going to boom anti-two-block switch and attach to
quick coupler on jib anti-two-block wire on rear of jib
between the upper and lower jib ears.

19. For manually extendable jibs, pull extension retention
pin E, and extend second section out by pulling on
sheave case. The second section jib, as it extends, will
hit a mechanical stop that allows for extension pin E
installation. Install pin E and spring clip.
