OPERATION

PRECAUTIONS FOR WORKING ON SLOPE

k k
• When performing the swing operation or operating the
work equipment on slopes, machine may lose its bal-
ance and tip over. Avoid such operations as much as
possible.
It is particularly dangerous to swing downhill when the
bucket is loaded.
If it is unavoidable to perform such operations, pre-
pare an embankment to make a platform (A) on the
slope so that the machine is horizontal.
• Do not operate or drive the machine on a slope cov-
ered with the steel plates. Even with slight slopes
there is a hazard that the machine may slip.
• Do not drive the machine up or down on steep slopes.
There is a danger that the machine may turn over.
• When travelling, raise the bucket approximately 20 to
30 cm above the ground.
Do not drive the machine downhill in reverse.
• Never turn on slopes or drive across slopes.
Go down to a flat place once, and take a safer way
such as a detour.
• Stay alert while driving and operating the machine in
order to stop it safely when the machine slips or be-
comes unstable.
• When the machine is travelling uphill, if the shoes slip
or it is impossible to travel uphill with using only the
force of the tracks, do not use the pulling force of the
arm to help the machine travel uphill. There is a dan-
ger that the machine may tip over. Accordingly, don't
drive the machine uphill with this method.
• Never perform the swing operation on a slope by us-
ing the left work equipment control lever even if the
engine is stopped. Otherwise, the upper structure will
swing under its own weight.
• Do not open or close the door when the machine is on
a slope. The operating effort may suddenly change. Al-
ways lock the doors of the operator's compartment in
position regardless of whether it is open or closed.
1.
When travelling down steep hills, use the travel lever and
fuel control dial to keep the travel speed low.
When travelling down a steep hill of more than 15°, set the
work equipment to the posture shown in the figure, and
travel at low engine speed.
