TRAVELING ON SLOPES 3
WARNING
q
Turning or operating the work equipment when work-
ing on slopes may cause the machine to lose it bal-
ance and turn over, so avoid such operations.
It is particularly dangerous to swing downhill when the
bucket is loaded.
If such operations have to be performed, pile soil to
make a platform (A) on the slope so the machine is
kept horizontal during operation.
q
Do not travel up or down steep slopes. There is a dan-
ger that the machine may turn over.
q
When traveling, raise the bucket approx. 20 to 30 cm
from the ground.
Do not travel downhill in reverse.
q
Never turn on slopes or travel across slopes.
Always go down to a flat place to perform these opera-
tions. It may be longer, but it will ensure safety.
q
Always operate or travel in such a way that it is possi-
ble to stop safely at any time if the machine slips or
becomes unstable.
q
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
machine travel uphill. There is danger that the
machine may turn over.
1. When traveling down steep hills, use the travel lever and
fuel control dial to keep the travel speed low. When travel-
ing down a steep hill of more than 15°, set the work equip-
ment to the posture shown in the diagram on the right, and
lower the engine speed.
2. When traveling up a steep hill of more than 15°, set the
work equipment to the posture shown in the diagram on
the right.
