PRECAUTIONS FOR WORKING ON SLOPE
• Swinging operations or operating the work equipment
on slopes machine may lose its balance 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 work or travel on a slope covered with the steel
plates. Even with slight slopes, there is a hazard that
the machine may slip.
• Do not travel up or down on steep slopes. There is a
danger that the machine may turn over.
• When driving the machine, raise the bucket approxi-
mately 20 to 30 cm above the ground.
Do not travel downhill in reverse.
• Never turn on slopes or travel 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 traveling uphill, if the shoes slip or it is impossi-
ble to travel uphill using only the force of the tracks,
do not use the pulling force of the arm to help the ma-
chine travel uphill. There is danger that the machine
may tip over. Accordingly, do not travel uphill with this
method.
• When traveling down steep hills, use the travel lever and
fuel control dial to keep the travel speed low.
When traveling down a steep hill of more than 15 °, set the
machine to the posture shown in the figure with sprocket
(1) downward and lower the engine speed.
(a): 20 to 30 cm
REMARK
Travel down with sprocket (1) downward.
If the machine travels down with sprocket (1) upward, the
tracks may be loosened and may jump teeth.
