Install Jib Load Line
The Drum 2 load line is used for the lower jib point. This line
has multi-part reeving. The Drum 3 load line is used for the
upper jib point, if equipped.
See Wire Rope Specifications to determine parts of line
required for your job and size load block accordingly. See the
Fixed Jib Capacity Charts for capacity limitations.
Route load lines through proper guide sheaves on boom
butt, mast, boom top, and jib top. See Load Line Reeving in
this section for proper routing and reeving of the load lines.
Connect Electric Cords
Connect electric cords to respective junction boxes and
switches in boom and jib (see Boom Wiring and Limits
Drawing at the end of this section).
Connect all unused electric cords to proper terminating plugs
on junction boxes. Boom will not lower and drums will not
hoist if electric cords are not shorted out.

Install wind speed indicator if removed for shipping. Use star
washers to attach mounting bracket to jib top to provide good
a ground (see Wind Speed Assembly drawing at the end of
