7. PRECAUTIONS DURING OPERATION
WORKING ON LOOSE GROUND
• Do not operate the machine on soft ground. It is difficult to get the machine out again.
• Avoid operating your machine too close to the edge of cliffs, overhangs, and deep ditches. If these areas
collapse under the mass or vibration of your machine it could fall or tip over and this could result in serious
injury or death. Remember that the soil after heavy rain, blasting or earthquakes is weakened in these areas.
• Earth laid on the ground and the soil near ditches is loose. It can collapse under the mass or vibration of your
machine and cause your machine to tip over.
• Install the head guard (FOPS) when working in areas where there is danger of falling stones.
• Install the ROPS and wear the seat belt when working in areas where there is danger of falling rocks or of the
machine turning over.
PRECAUTIONS WHEN WORKING ON SLOPES
• When working on slopes, there is danger that the machine may lose its balance and turn over when the
swing or work equipment are operated. Always carry out these operations carefully.
• Do not swing the work equipment from the uphill side to the downhill side when the bucket is loaded. This
operation is dangerous.
• If the machine has te be used on a slope, pile the soil to make a platform that will keep the machine as
horizontal as possible.
