PRECAUTIONS FOR OPERATION
If you drive the machine at high speed continuously for a long time, the tires will overheat and the internal
pressure will become abnormally high. This may cause the tires to burst. If a tire bursts, it produces a large
destructive force, and this may cause serious injury or death.

PRECAUTIONS WHEN TRAVELING ON SLOPES

To prevent the machine from tipping over or slipping to the side, always observe the following.
Keep the work equipment at height (A) of approximately 20
to 30 cm above the ground. In case of emergency, lower
the work equipment to the ground immediately to help
stopping the machine.
Always drive the machine straight up or down a slope.
Driving the machine at an angle or across the slope is ex-
tremely 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.
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.
If the engine should stop on a slope, depress the brake pedal immediately, lower the bucket and apply the
parking brake to stop the machine.
When driving the machine downhill, drive it slowly at low speed. Depress the brake pedal or use the engine
brake as necessary.
When the bucket is loaded, direct the bucket toward the hill top both in uphill and downhill travel. When
driving the machine with the bucket directing downhill, it is liable to tip over and is dangerous.

METHOD OF USING BRAKES

Do not put your foot on the brake pedal unnecessarily. If the machine travels with your foot on the brake
pedal, the brake operates constantly and heats abnormally, and is disabled and that can cause an accident.
Do not depress the brake pedal repeatedly more than necessity.
When traveling downhill, always use the engine brake, and use the brake pedal as well.
