Traveling On Slopes - Komatsu PC220LC -8 Operation & Maintenance Manual

OPERATION

TRAVELING ON SLOPES

Turning or operating the work equipment when working on slopes may
cause the machine to lose it balance 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.
Do not work 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 steep slopes. There is a danger that the
machine may turn over.
When traveling, raise the bucket approx. 20 to 30 cm (8 to 12 in) from the
ground.
Do not travel downhill in reverse.
Never turn on slopes or travel across slopes.
Always go down to a flat place to perform these operations. It may be
longer, but it will ensure safety.
Always operate or travel in such a way that it is possible to stop safely
at any time if the machine slips or becomes unstable.
When traveling uphill, if the shoes slip or it is impossible 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 traveling down
a steep hill of more than 15°, set the work equipment 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.
