PRECAUTIONS FOR OPERATION
SAFETY
2-24
TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the side, always do as follows.
q
Keep the work equipment at height (A) (70 - 90 cm above
the ground) so that it can be lowered immediately to the
ground to stop the machine in case of emergency.
q
Always travel straight up or down a slope. Traveling at an
angle or across the slope is extremely dangerous.
q
Do not turn on slopes or travel across slopes. Always go
down to a flat place to change the position of the machine,
then travel on to the slope again.
q
Travel on grass, fallen leaves, or wet steel plates with low speed. Even with slight slopes there is a hazard
that the machine may slip.
q
If the engine stops, depress the brake pedal immediately, lower the bucket to the ground, and apply the park-
ing brake to stop the machine.
q
When traveling downhill, never shift gear or place the transmission at neutral. It is dangerous not to use the
braking force of the engine. Always place the transmission in a low gear before starting to travel downhill.
q
When traveling downhill, travel slowly. If necessary, use the braking force of the engine together with the brake
pedal to control the travel speed.
q
When traveling up or down hills with a loaded bucket, always travel with the bucket facing uphill. If the
machine travels with the bucket facing downhill, there is danger that the machine may tip over.
