PRECAUTIONS FOR OPERATION
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.
• 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, falling rocks, or flooding.
• Lower the work equipment to the ground.
• When leaving the machine, set work equipment lock lever
(1) and parking brake lever (2) to LOCK position (L), and
stop the engine.
• Always close the operator's cab door, and use the key to
lock all the equipment in order to prevent any unauthorized
person from moving the machine. Always remove the key,
take it with you, and keep it in the specified place.
• If it is necessary to park the machine on a slope, always
observe the following.
• Set the work equipment on the downhill side and dig it
into the ground.
• In addition, block the tracks from movement.
