SAFETY
PRECAUTIONS FOR OPERATION
2-29
TRAVELING ON SNOW-COVERED OR FROZEN SURFACES
q
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.
q
With frozen ground surfaces, the ground becomes soft when the temperature rises, and this may cause the
machine to tip over or make it impossible for the machine to escape.
q
If the machine enters deep snow, there is a hazard that it may tip over or become buried in the snow. Be care-
ful not to leave the road shoulder or to get trapped in a snow drift.
q
When clearing snow, the road shoulder and objects placed beside the road are buried in the snow and cannot
be seen. There is a hazard of the machine tipping over or hitting covered objects, so always carry out opera-
tions carefully.
PARKING MACHINE
q
Park the machine on firm, level ground.
q
Select a place where there is no hazard of landslides, fall-
ing rocks, or flooding.
q
Lower the work equipment completely to the ground.
q
When leaving the machine, set lock lever (1) to the LOCK
position (L), then stop the engine.
q
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.
q
If it is necessary to park the machine on a slope, always do
as follows.
q
Set the work equipment on the downhill side and dig it
into the ground.
q
In addition, put blocks under the tracks to prevent the
machine from moving.
