6. OPERATION
When using a crane, remember to set the engine in low idling mode and work in a speed as low
as possible. If you operate a lever in a sudden motion, the searcher hook might break due to the
excess force, causing a serious accident.
CAUTION
In this section, only the operation procedure for the searcher hook specification that is different
from the standard specification is described.
The normal crane operation is the same as the standard specification. For details, refer to
“Operation 2. Operation”.
6.1 CHANGING SEARCHER HOOK ANGLE
• Never put your fingers into the pin hole. If you remove, it may cause a serious bodily accident.
• When changing the angle, the searcher hook boom might fall suddenly after pin is pulled out,
so be sure to support the boom before changing pins.
• After changing the angle of the searcher hook, change “OFFSET POSITION” on the monitor
according to the actual angle. If you use the machine without changing the mode, damage to
or overturn of the machine might occur causing a serious accident.
To change the searcher hook angle, follow the procedure below. The following procedure assumes the
starting point is “Offset Position 0°”.
[When Offset Position is -14°]
1. Keep the pin B (10) in the Offset Position 0° status, and move
the pin A (9) to the hole on one level down.
[When Offset Position is 20°, 40°, 60°, 80°]
1. Keep the pin A (9) in the Offset Position 0° status, and move
the pin B (10) to the hole for the desired angle.
