Methods of using brake
z 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.
z Do not depress the brake pedal repeatedly if not necessary.
z When traveling downhill, use the braking force of the engine.
If necessary, use the brake pedal at the same time.
Operate carefully on snow
z Snow-covered or frozen surfaces are slippery, so be
extremely careful when travelling 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.
z With frozen ground surfaces, the ground becomes soft when
the temperatures rises and this may cause the machine to
tip over.
z
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.
z
When clearing snow, the road shoulder and 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 operations carefully.
z
When travelling on snow-covered roads, always fit tire
chains.
z
When travelling 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 intermittenly
(depress the brake intermittenly several times). If nessecary,
lower the bucket to the ground to stop the machine.
