1. Extend and set the outriggers.
2. Rotate the upper structure to the “over rear” position.
3. Retract the boom completely.
4. Boom down to minimum boom angle to allow ease of
installation of the jib pins. If necessary raise rear out-
riggers till boom head can be reached from ground
level.
5. Install the upper and lower jib mounting pins in the
right side of the boom head.
6. Attach a guide rope to the eye on the bottom tip of
the jib.
7. Extend outriggers if retracted, to bring crane back to
level. Raise the boom to horizontal.
8. Pull down and rotate the T - handle to unlock the jib
from the storage bracket.
9. With the engine at idle, slowly extend the boom 2-3
feet (.6-1 m). As the jib clears the storage brackets,
the jib will swing out approximately 45°.
Booming down to quickly can result in damage
to jib.
10. With the engine at idle, slowly boom down to mini-
mum boom angle while another operator uses the
guide rope to control the speed of the jib rotation.
The jib will swing around until the left side mount-
ing holes line up.
11. If cable from main boom is to be used on jib,
remove cable from boom head load sheaves and
swing over top left jib cord before pinning jib to
boom. Install the left upper and lower jib mounting
pins.
12. Remove the guide rope.
13. Disconnect the anti two-block plug from the jib anti
two-block socket and connect it to the socket on
the boom head. Move the dummy plug from the
boom head socket to the anti two-block socket on
the jib.
14. Reeve the hoist line over the jib sheave.
15. Test the anti two-block system by lifting the anti
two-block weight. The light and audible alarms
should be actuated in the cab and the boom down,
boom extend, and winch up controls should dis-
connect.
