PRECAUTIONS FOR OPERATION
SAFETY
2-24
TRAVELING ON SLOPES
To prevent the machine from tipping over or slipping to the side, always do as follows.
q
When traveling on slops, keep the blade approxmately 20
to 30 cm above the ground. In case of emergency, quickly
lower the blade to the ground to help the machine to stop.
Apply the brake and use the engine as a brake, if neces-
sary.
q
Always travel straight up or down a slope. Traveling at an
angle or across the slope is extremely dangerous.
q
Do not turn on slopes or travel across slopes. Always go
down to a flat place to change the position of the machine,
then travel on to the slope again.
q
Travel on grass, fallen leaves, or wet steel plates with low
speed. Even with slight slopes there is a hazard that the
machine may slip.
q
Do not shift the gear while traveling downhill or travel downhill with the transmission in neutral. If this is
neglected, the engine does not work as a brake, and that is dangerous. Be sure to set the transmission in one
of the lower gear speeds. In addition, apply the brake and use the engine as a brake, if necessary.
q
When turning on a downhill ground, lower the travel speed.
PROHIBITED OPERATIONS
q
To make it easier to escape if there is any problem, set the tracks at right angles to the road shoulder or cliff
with the sprocket at the rear when carrying out operations.
q
When operating the machine, take care that it will not exceed its performance values such as stability, maxi-
mum using load, etc. to prevent rolling of the machine caused by an overload and disasters caused by break-
age of the work equipment.
USING BRAKES
q
When the machine is traveling, do not rest your foot on the brake pedal. If you travel with your foot resting on
the pedal, the brake will always be applied, and this will cause the brakes to overheat and fail.
q
Do not depress the brake pedal repeatedly if not necessary. If this is neglected, the brake will be overheated
and will not work when required.
q
When traveling downhill, use the braking force of the engine, and always use the right brake pedal.
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 traveling on snow-covered slopes, never apply the brakes suddenly. Reduce the speed and use the
engine as a brake while appling the foot brake intermittently (depress the brake intermittently several times). If
necessary, lower the blade to the ground to stop the machine.
