12. OPERATION

12.11 PROHIBITIONS FOR OPERATION

• If it is necessary to operate the work equipment control lever
when the machine is travelling, stop the machine before oper-
ating the work equipment control lever.
• If the lever is moved inside the deceleration range, engine
speed will suddenly rise. Operate the levers carefully.
• Never operate the machine on a rock bed (hard or soft rock).
Prohibited operations using swing force
Do not use the swing force to compact soil or break earth mounds or
walls.
When swinging, do not dig the bucket teeth into the soil. These op-
erations will damage the work equipment.
Prohibited operations using travel force
Do not leave the bucket dug into the ground and use the travel force
to excavate. This will bring excessive force to bear on the rear of the
machine.
Precautions when operating hydraulic cylinders to end of stroke
If the cylinder is operated to the end of its stroke during operations,
force will be brought to bear on the stopper inside the cylinder, and this
will reduce the life of the machine. To prevent this, always leave a small
safety margin when operating the cylinders.
Prohibited operations using dropping force of bucket
Do not use the dropping force of the bucket as a pickaxe, breaker, or
pile driver. This will bring excessive force to bear on the rear of the ma-
chine, and will not only damage the machine, but is also dangerous.
