1.14 OPERATE DIGGING WORK SAFELY

Before digging, operator should be aware of the
position of the embedded lines, such as cable, gas
pipe, water supply pipe, and operate the machine
carefully to prevent accident.

All the non-working people should be away from the
working range of machine.

Make sure the ground of working site is hard enough
to support machine.

When the machine works at pithead, the tension
wheel end should be outward pithead, keeping the
traveling orientation vertical with pit cliff. In this way,
the machine can move away easily when the cliff
collapses.

When the machine works in deep spot, you should
prevent the boom bottom and cylinder from colliding
with high objects.

Turn over prevention
When the machine works on slope, the track should
be parked along the slope, retract the bucket as much
as possible, keep the bucket close to ground and
machine to avoid turning over.
When swinging with load, decrease swing speed to
avoid turning over. When work on frozen ground, you should prevent the ascending
temperature from causing the ground to soften, otherwise it will affect the stability of
machine.

During operation, prevent boom or arm from colliding with high objects.

The bucket is only for digging work, do not allow using bucket to work as pneumatic pick or
hydraulic breaker does.
