PRECAUTIONS FOR OPERATION
When traveling on a level ground, keep the work equip-
ment approximately 40 to 50 cm above the ground. If that
height is not maintained between the work equipment and
the ground, the work equipment may get stuck in the
ground and the machine may tip over.
Try to avoid traveling over obstacles. If the machine has to
travel over an obstacle, keep the work equipment close to
the ground and travel at low speed. The machine tips over
easily to the right or left. Do not drive it over obstacles
which make the machine tilt largely to the right or left.
When driving the machine on the rough ground, drive it at
low speed and do not operate the steering suddenly. There
is a danger that the machine may tip over. The work equip-
ment may hit the ground, and the machine may lose its
balance, or it may damage the machine or structures in the
area.
When using the machine, to prevent serious personal injury or death caused by the work equipment or by
the machine tipping over due to overloading, do not use the machine beyond the permitted performance of
the machine such as the maximum permitted load for the structure of the machine.
When passing over bridges or structures, check first that the structure is strong enough to support the
weight of the machine.
When operating in tunnels, under bridges, under electric wires, or other places where the height is limited,
operate slowly and be extremely careful not to let the machine body or work equipment hit anything.

PRECAUTIONS WHEN TRAVELING ON SLOPES

To prevent the machine from tipping over or slipping to the side, always observe the following.
Never turn the key in the starting switch to OFF position
when the machine is traveling downhill. If the engine stops
when the machine is traveling, it may become impossible
to operate the steering, and this may cause serious per-
sonal injury or death. If the engine stops, depress the
brake pedal immediately to stop the machine.
Keep the work equipment approximately 20 to 30 cm
above the ground. In case of emergency, lower the work
equipment to the ground immediately to help stop the ma-
chine.
Always drive the machine straight up or down a slope.
Driving the machine at an angle or across the slope is extremely dangerous.
Do not turn on slopes or drive across slopes. Always go down to a flat place to change the position of the
machine, then drive it on to the slope again.
Do not drive the machine on a slope covered with the steel plates. Even with slight slopes there is a hazard
that the machine may slip.
Drive the machine at low speed on the grass or fallen leaves. Even with slight slopes, there is a hazard that
the machine may slip.
When traveling downhill, never shift gear or place the transmission at neutral. Engine brake does not work
and dangerous. Always set the transmission to a low gear before starting to travel downhill.
Depress the brake pedal or use the engine brake as necessary.
