Installation
The block-up limit controls must be installed according to
Boom Wiring, Limits and Load Indicator Electrical Assembly
drawing in the 999 Operator Manual.
See Figure 5-7
for installation of the weights.
Storing Electric Cable
The electric cables for the boom, fixed jib, and luffing jib are
long enough to accommodate the maximum length of each
attachment.
Store the excess cable for the boom and luffing jib on the reel
mounted on either butt (Figure 5-5
). The reel is equipped
with a locking pin. Disengage the locking pin to allow the reel
to be wound. Engage the locking pin to lock the reel in
position. The power supply cable to the reel must be
disconnected before the reel can be wound.
Store the excess electric cable for the fixed jib by winding it
around the brackets on the fixed jib butt (Figure 5-5
).
