Traveling on slopes
To prevent the machine from tipping over or slipping to the side,
always do as follows.
z When traveling on slopes, keep the bucket at height “A“ of
approximately 200 to 300 mm (8 to 12 in) above the ground.
In case of emergency, quickly lower the bucket to the ground
to help the machine to stop.
z
Always travel straight up or down a slope. Traveling at an
angle or across the slope is extremely dangerous.
z
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.
z
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.
z If the engine stops, depress the brake pedal immediately,
lower the bucket to the ground, and apply the parking brake
to stop the machine.
z
When traveling downhill, never shift gear or place the trans-
mission 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.
z When traveling downhill, travel slowly. If necessary, use the
braking force of the engine together with the brake pedal to
control the travel speed.
z 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.
