Traveling On Slopes; Operate Carefully On Snow - Komatsu 930E-2 Shop Manual

TRAVELING ON SLOPES

•
Traveling on slopes could result in the machine tipping over or slipping.
•
Do not change direction on slopes. To ensure safety, go down to level ground before turning.
•
Do not travel up and down on grass, fallen leaves, or wet steel plates. These materials may make the machine
slip on even the slightest slope. Take all possible steps to avoid traveling sideways, and always keep the travel
speed low.
•
When traveling downhill, use the retarder to reduce speed. Do not turn the steering wheel suddenly. Do not use
the foot brake except in an emergency.
•
If the engine should stop on a slope, apply the brakes fully and apply the parking brake to stop the machine.
ENSURE GOOD VISIBILITY
•
When working in dark places, install working lamps and head lamps, and set up lighting in the work area if
necessary.
•
Stop operations if the visibility is poor, such as in mist, snow, or rain, and wait for the weather to improve to a
condition that allows the operation to be carried out safely.

OPERATE CAREFULLY ON SNOW

•
When working on snowy or icy roads, there is danger that the machine may slip to the side on even the slightest
slope, so always travel slowly and avoid sudden starting, turning, or stopping.
•
Be extremely careful when carrying out snow-clearing operations. The road shoulder and other objects are buried
in the snow and cannot be seen. When traveling on snow-covered roads, always install tire chains.
AVOID DAMAGE TO DUMP BODY
•
When working in tunnels, on bridges, under electric cables, or when entering a parking place or any other place
where there are height limits, always drive extremely carefully and lower the dump body completely before driving
the machine.
DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES
•
Going close to high-voltage cables can cause electric shock. Always maintain the safe distance given below
between the machine and the electric cable.
•
The following actions are effective in preventing accidents:
1) Wear shoes with rubber or leather soles.
2) Use a signalman to give warning if the machine approaches too close to the electric cable.
•
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 electrical maintenance department about the voltage of the cables before starting operations.
