Loose ground may easily give way under weight of the machine.
When working on loose or unstable ground, it is important not to
dig too deep and to carefully reposition the machine. Do not
panic and do not raise bucket, if ground should begin to
collapse. Lower work equipment to improve stability of machine.
Never dig under machine, if there is a potential of causing a
landslide.
High-voltage Cables
Do not travel or operate machine near electrical cables or
overhead power lines. There is a hazard of electric shock, which
can cause property damage and result in death or serious injury.
The bucket or other attachment does not have to make physical
contact with power lines for current to cause an electrocution.
Use a spotter and hand signals to stay away from power lines
not clearly visible to operator. On work sites where machine may
operate close to electrical cables, always do the following:
•
Remember that electrical voltage determines what the
minimum distance is to stay away from the power line. See
the following table for minimum distances when working
near electrical power lines. Electrical flashover can occur
and damage machine and cause death or serious injury.
•
Always contact the power company responsible before
beginning work near high voltage power lines.
