2.4.9 VISIBILITY
2.4.10 WORKING ON ICY OR SNOW-COVERED SURFACES
2.4.11 PREVENTING DAMAGE CAUSED BY THE WORK EQUIPMENT
2.4.12 WORKING ON LOOSE GROUND
•
Switch on the working lights as soon as visibility decreases.
•
If visibility decreases due to mist, smoke or heavy rain, stop the machine in a safe position and wait for the
weather to improve until visibility becomes acceptable.
•
If the ground is icy or covered with snow, even a slight slope may cause the machine to slip sidewards, there-
fore it is advisable to move at low speed and to avoid abrupt starts, stops or turns.
•
When it has snowed heavily, the road shoulders and any obstacle are buried in the snow and are not visible,
therefore proceed with care when clearing the snow.
•
When working in tunnels, galleries, under electric cables or other ducts (air, telephone lines) and wherever the
height is limited, proceed with the greatest care to prevent the bucket or the arms from causing any damage.
•
Avoid operating the machine too close to the edge of cliffs, overhangs and deep ditches.
These areas may collapse, making the machine fall down or tip over and this could result in serious injuries or
death.
Remember that after heavy rain or earthquakes these dangerous conditions usually get worse.
•
The earth laid near ditches is loose and can easily collapse due to the weight or vibrations of the machine.
Be extremely careful: always fasten the safety belt and close the cab door, if provided.
•
In case of work in areas where stones or other material may fall on the machine, install the FOPS protection de-
vice.
