20) Do not dig the working surface under the suspended
part, otherwise, there will be the danger of falling rocks or
the suspended part collapsing and hitting the machine.
5. Anti-dumping, anti-skidding and disposal during operation
Warning: 1) When you have to turn on a ramp, you can only turn in a large arc. When the machine is
about to turn to the right, extend the boom and stick to the left, the bucket is about 30 cm away from
the ground, and lock the platform. Vice versa.
2) When skidding, immediately press the bulldozer shovel and bucket to the ground.
3) When the machine is overturned, the driver must not jump off the car, but should firmly grasp the
handrail in the cab or the column of the cab. Jumping from a car can easily cause casualties.
The machine is extremely easy to tip over in the following
situations and must be avoided:
1)
The machine shifts on uneven ground, with two
tracks high on one side and low on the other, or more
than half of one track is suspended in the air.
2)
When one track contacts loose soil and the other
track contacts solid soil.
3)
When there is a cave or mud pit in the ground on one
side of the machine.
4)
When walking on a slope with a longitudinal gradient
greater than 25°, and unloading heavy objects in the
downhill direction.
5)
When walking on a slope with a lateral gradient
greater than 15°, and unloading heavy objects in the
downhill direction.
6)
On the slope, the two tracks and the slope are in a
direction of 90°, and the platform rotation is greater
than 90°.
7)
When working on a slope, the machine turns sharply,
the platform turns quickly or stops suddenly.
8)
When the machine swings down 180° on a slope.
9)
When the road surface where the machine moves on
is uneven during the backward operation (trenching,
etc.).
10) When the machine is digging deep to the bottom of
the machine body.
11) Walking on the frozen ground.
12) When the two tracks are stuck with oil or lubricating
oil, the machine is easy to slip.
