SAFETY
PRECAUTIONS DURING OPERATION
RECAUTIONS UNDER THE SNOWING AND FREEZING CONDITION
Snow-covered or frozen surfaces are slippery, so be extremely careful when traveling or operating the machine,
and do not operate the levers suddenly. Even a slight slope may cause the machine to slip, so be particularly
careful when working on slopes.
With frozen ground surfaces, the ground becomes soft when the temperature rises, and this may cause the
machine to tip over.
If the machine enters deep snow, there is a hazard that it may tip over or become buried in the snow. Be careful
not to leave the road shoulder or to get trapped in a snow drift.
When traveling on snow-covered roads, always fit tire chains.
When traveling 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 (depress the brake intermittently several times). If
necessary, lower the bucket to the ground to stop the machine.
When the loaded materials in the dump body are frozen, do not dump. There is a danger that the machine could
tip over.
PRECAUTIONS FOR PARKING
Park the machine on firm, level ground.
Select a place where there is no hazard of falling rocks or
landslides, or of flooding if the land is low.
When leaving the machine, place the gear shift lever (1) at
neutral and set the parking valve lever (2) to the PARKING
position. Then, 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 leave it in the specified place.
If it is necessary to park the machine on a slope, set blocks
under the wheels to prevent the machine from moving.
