7. PRECAUTIONS DURING OPERATION WARNING: Failure to follow these safety precautions may lead to a serious accident. 1-15 METHOD OF USING BRAKES ‡ Do not put your foot on the brake pedal unless necessary. ‡ Do not depress the brake pedal repeatedly unless necessary. ‡ When traveling downhill, use the engine as a brake, and always use the right brake pedal. 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 electric cable. ‡ To prevent accidents, always do as follows.
• On jobsites where there is danger that the machine may touch 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 warning 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 compartment.
• 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.

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 traveling.
‡ 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 snow-clearing operations carefully. ‡ When traveling on snow-covered roads, always fit tire chains. ‡ When traveling 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.
