PROHIBITION OF OPERATIONS USING MACHINE DROPPING FORCE
Do not use the dropping force of the machine for digging.
PROHIBITION OF DIGGING OPERATION AT AN ANGLE WITHOUT ENGAGING
TEETH
If the machine swings and digs simultaneously while the bucket
blade does not bite into hard rocks at a position higher than the
machine, the teeth slide down on the rock surfaces. As a result,
large vibration occurs in the machine and can crack the work
equipment or frame.
If the bucket blade slides and collides with a rock, an excessive
impact load occurs in the work equipment and frame and can
shorten the service life of the machine.
PROHIBITION OF DIGGING OPERATION ON HARD ROCKY GROUND
Do not attempt to directly excavate hard rocky ground with the work equipment. It is better to excavate it after
breaking up by some other means. This will not only save the machine from damage but will make for better
economy.
