number of wire falls options.

DANGER! Do not use 850 kg searcher hook if
actual searcher hook offset position and
display of boom length windows do not
match. Without setting moment limiter to the

and could cause a serious accident.

selector switch to set searcher hook offset
position shown in the boom length window.

mode, press fall mode/option selector switch
(24) and cancel switch (23) at the same time for

position and mode display in boom length
window" on page 4-143.
Pressing fall mode/option selector switch (24)
and cancel switch (23) at the same time for 2
seconds or more shifts boom length display in
