DANGER! When hoisting a load with a
searcher hook, raise boom to hoist the load
off the ground, and stop for a while to check if
the load is safe to hoist.
NOTICE: Characteristic of moment limiter display
• At certain working conditions, moment limiter
may display bigger load value than actual load.
• Sudden lever operation increases error in
reading load. When operating boom lift lever,
move the lever slowly.
11. If the boom stops automatically on entering
the overload area while being lowered or
extended, retract the boom and move to a
safe area before lowering the boom to lower
the load. If it becomes necessary to raise the
boom while automatically stopped, the boom
can be raised only while the Boom Lift
Bypass Switch is depressed.
DANGER! Use the Boom Lift Bypass Switch
only when the boom has stopped
automatically after entering the overload area
while being lowered. When the boom has
stopped automatically after entering the
overload area while being extended, retract
the boom. Never use this switch in normal
situations to lift loads off the ground. Serious
accidents such as machine damage or
toppling may occur if you use this switch to
lift loads off the ground.
