SAFETY
PRECAUTIONS FOR OPERATION
2-23
OPERATE CAREFULLY ON SNOW
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.
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.
q
When operating on slow-covered slopes, never use the brakes to stop the machine suddenly. Reduce the
speed and use the engine as a brake together with operating the brake pedal. If necessary, lower the blade to
the ground to stop the machine.
PARKING MACHINE
q
Park the machine on firm, level ground.
q
Select a place where there is no hazard of falling rocks or
landslides, or of flooding if the land is low.
q
Lower the work equipment completely to the ground.
q
When leaving the machine, set the steering, directional
and gear shift levers in the N (Neutral) position and set the
blade lever in the HOLD position, then apply safety lock
lever (1) and parking lever (2) and 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 blade on the downhill side, then dig it into the
ground.
q
Put blocks under the tracks to prevent the machine
from moving.
