Prohibited operations
z It is dangerous to excavate the bottom of a rock face. Never
do this.
z When digging, never thrust the bucket into a load at an
angle. This will bring an excessive load to bear on the
machine and will reduce the service life of the machine.
z It is dangerous to apply drive force when excavating a rock
face. In addition, an excessive load will be brought to bear
on the machine and this will cause damage to the machine.
z Never carry out digging operations on a downhill slope. An
excessive load will be brought to bear on the machine and
this will cause damage to the machine.
z
It is dangerous to use the bucket or lift arm for crane opera-
tions, so do not carry out such operations.
z
Do not pass the bucket over the head of other workers or
over the operator’s seat of dump trucks or other hauling
equipment. The load may spill or the bucket may hit the
dump truck and cause serious injury or property damage.
