• Prior to the crane operation, always place the machine on level and solid ground. Use the level
to ensure this.
• In the event that a crane operation during traveling is un-avoidable, always stop traveling first,
then carry out the crane operation. Controls of both the left and right work equipment control
levers during traveling are not available to this machine, except swinging and boom retraction.
• See the cautions given in the Safety besides the dos and don’ts in this section.
[1] DON’T OPERATIONS WITH SLEWING FORCE
Drawing in or lifting the load with slewing operation is prohibited.
[2] DON’T OPERATIONS WITH DERRICKING FORCE
Drawing in or lifting the load with boom derricking operation is
prohibited.
[3] DON’T PULL SIDEWAYS， DRAW IN， OR HOIST DIAGONALLY
Pulling sideward, drawing in, or hoisting diagonally applies
unreasonable force on the machine. It not only damages the
machine body, but also is dangerous. Never operate in these ways.
The hook must come right above the center of gravity of the load
hoisted.
[4] DON’T OPERATE VIOLENTLY DURING OPERATION
Do not operate the lever suddenly.
Especially, the “slewing”, “boom lowering”, and “hook lowering”
must be operated at low speed.
[5] DO NOT ALLOW ACCESS INTO WORKING RADIUS
Do not let people access the working radius area such as
permitting an operator to go under the hoisted load.
