PROHIBITIONS FOR OPERATION

If it is necessary to operate the work equipment control
G
lever when the machine is traveling, stop the machine
before operating the work equipment control lever.
If the lever is moved inside the deceleration range,
G
engine speed will suddenly rise. Operate the levers care-
fully.
Never operate the machine on a rock bed (hard or soft
G
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
operations 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 opera-
tions, force will be brought to bear on the stopper inside the cylin-
der, and this will reduce the life of the machine. To prevent this,
always leave a small safety margin when operating the cylinders.
