WARNING: Failure to follow
these safety precautions may
lead to a serious accident.
DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES
• Do not let the machine touch overhead electric cables. Even going close to high-voltage cables can cause
electric shock. Always maintain the safe distance given below between the machine and the elctric cable.
• To prevent accidents, always do as follows.
On job sites where there is danger that the machine may touck the electric cables, consult the electricity
company before starting operations to check that the actions determined by the relevant laws and
regulations have been taken.
Wear rubber shoes and gloves. Lay a rubber sheet on top of the operator's seat, and be careful not to
touch the chassis with any exposed part of your body.
Use a signalman to give worning if the machine approaches too close to the electric cables.
If the work equipment should touch the electric cable,the operator should not leave the operator's com-
partment.
when carrying out operations near high voltage cables, do not let anyone come close to the machine.
Check with the electricity company about the voltage of the cables before starting operations.

OPERATE CAREFULLY ON SNOW
• When working ons now or icy roads, even a slight slope may cause the machine to slip to the side, so always
travel at low speed and avoid sudden starting, stopping, or turning. There is danger of slipping particularly on
uphill or downhill slopes.
• With frozen road surfaces, the ground becomes soft when the temperature rises, so the travel conditions
become unstable. In such cases be extremely careful when travelling.
• When there has been heavy snow, the road shoulder and objects placed beside the road are buried in the
snow and cannot be seen, so always carry out operations carefully.
When travelling on snow-covered slopes, never apply the brakes 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.
• The load varies greatly according to the characteristics of the snow, so adjust the load accordingly and be
careful not to let the machine slip.
