SAFETY

WHEN OPERATING

Be careful not to approach too close to the edge of cliffs. When making embankments or landfills, or when
dropping soil over a cliff, dump one pile, then use the next pile of soil to push the first pile.
The load suddenly becomes lighter when the soil is pushed over a cliff or when the machine reaches the
top of a slope. When this happens, there is danger that the travel speed will suddenly increase, so be sure
to reduce the speed.
If the machine moves with only either side of the blade loaded, its tail may swing. Take care.

PROHIBITED OPERATIONS

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 ma-
chine such as the maximum permitted load for the structure of the machine.

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.
Use the engine brake during downhill travel.

PRECAUTIONS WHEN OPERATING ON SNOW OR FROZEN SURFACES

Snow-covered or frozen surfaces are slippery, so be extremely careful when traveling or operating the ma-
chine, and do not perform abrupt lever operation. Machine may slip even on a slight slope. Be particularly
careful when working on slopes.
Frozen road becomes soft when the temperature rises, and the machine may tip over or be not able to es-
cape. Be particularly careful when working on frozen road.
It is dangerous that the machine enters deep snow. The machine may tip over or become buried in the
snow. Be careful not to go off the road or to get trapped in a drift of snow.
When performing snow removal, the road and objects placed beside the road are buried in the snow and
cannot be seen. Be careful.
There is a hazard of the machine turning over or hitting covered objects, so always perform operations
carefully. When traveling on snow-covered slopes, never apply the foot brake suddenly. Reduce the speed
and use the engine brake while applying the foot brake intermittently (depress the brake intermittently sev-
eral times). If necessary, lower the work equipment to the ground to stop the machine.

PRECAUTIONS WHEN PARKING MACHINE

Unexpected move of the parked machine can cause serious personal injury or death. Always observe the fol-
lowing.
Park the machine on a firm, level ground.
Select a place where there is no hazard of landslides, falling rocks, or flooding.
Lower the work equipment to the ground.
