• Do not pass the bucket over the heads of other workers or over the operator's seat of dump trucks or other
hauling equipment. There is a danger that the load may spill or the bucket may hit the dump truck and
cause serious personal injury or death.
• Generally speaking, the machine is more liable to tip over when the work equipment is at the side than
when it is at the front or rear of the machine.
Be extremely careful when swinging the work equipment from the front or rear to the side of machine while
it is carrying a load. It is dangerous that the machine may tip over.
• When using a breaker or other heavy work equipment, it is dangerous that the machine may lose its bal-
ance and tip over. When operating the machine on the flat ground as well as on slopes, observe the follow-
ing.
• Do not suddenly lower, swing, or stop the work equipment.
• Do not suddenly extend or retract the boom cylinder. It is dangerous that the machine may tip over by
the impact.
• In the operation using the fork or grapple, do not attempt to
pick up an object with the tips.
The picked up object can easily slip off. Machine may be
damaged, or personal injury or death may occur.
PRECAUTIONS WHEN OPERATING ON SNOW OR FROZEN SURFACES
• Snow-covered or frozen surfaces are slippery, so be extremely careful when driving 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.
• When travelling on snow covered slopes, never apply the foot brake suddenly. Reduce the speed and use
the engine as a brake while applying the foot brake intermittently. 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 firm, level ground.
• Select a place where there is no hazard of landslides, falling rocks, or flooding.
• Check that the turret is facing the oscillating front axle and align it with the lower chassis to get down from
the machine using the steps and the handles.
