SAFETY
S-9
INVESTIGATE JOB SITE BEFOREHAND
•
When working at the edge of an excavation or on a road
shoulder, the machine could tip over due to collapse of
the ground, possibly resulting in serious injury or death.
•
Investigate the configuration and ground conditions of
the job site beforehand to prevent the machine from
falling and to prevent the ground, stockpiles, or banks
from collapsing.
•
Make a work plan. Use machines appropriate to the
work and job site.
•
Reinforce ground, edges, and road shoulders as
necessary. Keep the machine well back from the
edges of excavations and road shoulders.
•
When working on an incline or on a road shoulder,
employ a signal person as required.
•
Never allow bystanders to enter the working area such
as swing radius or traveling range.
•
When the footing is weak, reinforce the ground before
starting work.
•
When working on frozen ground, be extremely alert.
As ambient temperatures rise, footing may become
loose and slippery.
•
When operating the machine near open flame, sparks,
and/or dead grass, a fire may easily break out. Use
special care not to cause a fire.
•
Make sure the work site ground has sufficient strength
to firmly support the machine. When working close to
an excavation or on road shoulders, operate the ma-
chine with the tracks positioned perpendicular to the
cliff face with travel motors at the rear and with the
blade at the front, so that the machine can more easily
evacuate if the cliff face collapses.
•
If working at the bottom of a cliff or on a high bank is
required, be sure to investigate the area first and con-
firm that no danger of the cliff or bank collapsing exists.
If any possibility of cliff or bank collapsing exists, do
not work in that area.
•
Soft ground may collapse when operating the machine
on it, possibly causing the machine to tip over. When
working on a soft ground is required, be sure to rein-
force the ground first using large pieces of steel plates
strong enough and firm to easily support the machine.
•
Note that there is always a possibility of machine tip-
ping over when working on rough terrain or on slopes.
Prevent machine tipping over from occurring. Operate
the machine slowly to ensure safe operation.
