PROHIBITED OPERATIONS

WARNING
• Do not operate the work equipment control lever when the machine is travelling.
• If any lever is operated when the auto-deceleration is being actuated, the engine speed will sudden-
ly increase, so be careful when operating.
PROHIBITION OF OPERATIONS USING SWING FORCE
Do not use the swing force to compact soil or break objects.
This is not only dangerous, but also drastically reduces the life
of the machine.
PROHIBITION OF OPERATIONS USING TRAVEL FORCE
Do not use the travel force to perform excavation by digging
the bucket into the ground. This damages the machine or work
equipment.
PROHIBITION OF OPERATIONS USING HYDRAULIC CYLINDERS TO STROKE
END
If the work equipment is used with the cylinder rod operated to
its stroke end, and given impact by some external force, the hy-
draulic cylinders may be damaged, causing personal injury. Do
not perform operations with the hydraulic cylinder fully retracted
or fully extended.
