NOTE: For Crane Serial Number 18001082 and newer
meeting 2010 European Requirements, the luffing
jib cannot be lowered after the jib maximum up 2
limit is contacted until the limit switch is reset.
When the limit is contacted, the screen shown in
Figure 3-13
will appear on the digital display.
Once the screen appears, confirm it to reset the
limit switch. The luffing jib can then be lowered.
Luffing Jib Down Limits
One or two luffing jib down limit stops are provided:
• MAX DOWN (past production minimum working angle):
automatically stops the luffing hoist when the boom to
luffing jib angle is 70°. This limit is controlled by a limit
switch.
• MAX DOWN 1 (current production minimum working
angle): automatically stops the luffing hoist when the
boom to luffing jib angle is 70°. This is a programmed
limit controlled by angle sensors on the boom and jib.
• MAX DOWN 2: automatically stops the luffing hoist
when the boom to luffing jib angle is 69° to 66°. This limit
is controlled by a limit switch.
Refer to Table 3-2
or Table 3-3 to determine if this limit can
be bypassed.
The luffing jib can be raised after the limit is contacted.
NOTE: For Crane Serial Number 18001082 and newer
meeting 2010 European Requirements, the luffing
jib cannot be raised after jib maximum down 2 limit
is contacted until the limit switch is reset. When the
limit is contacted, the screen shown in Figure 3-14
will appear on the digital display.
Once the screen appears, confirm it to reset the
limit switch. The luffing jib can then be raised.
Max Bail
Automatically stops the corresponding drum from hoisting
when there is a preset maximum number of wire rope layers
on the drum.
The load can be lowered after the limit is contacted.
The appropriate limit bypass switch must be turned to the
bypass position before a load can be hoisted above the limit.
Min Bail
Automatically stops the corresponding drum from lowering
when there are three wraps of wire rope remaining on the
drum.
The load can be raised after the limit is contacted.
The appropriate limit bypass switch must be turned to the
bypass position before a load can be lowered below the limit.
WARNING
Falling Boom/Jib Hazard!
Proceed slowly when operating the luffing jib above the
Max Up 1 limit.
Do not raise luffing jib above Max Up 2 limit. Structural

given in Wire Rope Specifications Chart in operator’s cab.
Wire rope could jump off drum allowing load to fall.
