WARNING: For reasons of safety, al-
ways follow these safety precautions.
7. PRECAUTIONS DURING OPERATION
• When working on slopes, there is danger that the machine may
lose its balance and turn over when the swing or work equip-
ment 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 dan-
gerous.
(See the upper diagram on the right.)
• If the machine has to be used on a slope, pile the soil to make a
platform that will keep the machine as horizontal as possible.
(See the lower diagram on the right.)

PARKING THE MACHINE
• Park on level ground whenever possible. If not possible, block the tracks, lower the bucket to the
ground and thrust the bucket in the ground.
• When parking on public roads, provide fences and signs, such as flags or lights, on the machine to
warn passersby to be careful. Be sure that the machine, flags or lights do not obstruct traffic.
