SAFETY

TRAVELING ON SLOPES

To prevent the machine from tipping over or slipping to the
side, always do as follows.
q Keep the work equipment approx. 20 to 30 cm above the
ground. In case of emergency, lower the work equipment to
the ground immediately to help stop the machine.
q When traveling uphill, set the machine with the operator's
seat on the uphill side; when traveling downhill, set the
operator's seat on the downhill side. Check that the
ground under the machine is safe when traveling.
q When traveling up a steep slope, extend the work equip-
ment to the front to improve the balance, keep the work
equipment approximately 20 to 30 cm above the ground,
and travel at low speed.
q When traveling downhill, lower the engine speed, keep the
travel lever close to the neutral position, and travel at low
speed.
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.
