PROHIBITED OPERATIONS
If the machine tips over or falls, or the ground at the working point collapses, it may lead to serious personal
injury or death. Always observe the following.
• Do not dig the work face under an overhangs. There is a
danger that the work face will collapse.
• When digging, never thrust the bucket into a load at an an-
gle. This will bring an excessive load on the machine and
will reduce the machine life.
• Wall surface digging by using of driving force is dangerous.
An excessive load will be brought on the machine and this
will cause damage to the machine. Never try such prac-
tice.
• Never perform digging operations on a downhill slope. An
excessive load will be brought on the machine and this will
damage the machine.
• Do not use the bucket or boom for crane operations. There
is a danger that the machine may tip over and the load
may fall.
• 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.
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.
• When traveling on snow-covered roads, always fit tire chains.
• 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.
• 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 several
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, fall-
ing rocks, or flooding.
• Set the machine to the straight travel condition, then lower
the work equipment to the ground.
