4. Unload the machine from the transport vehicle
1) It can be loaded and unloaded on solid and level ground, and keep a safe distance from the edge
of the road.
2) The transport vehicle is braked, and a pad is placed under the tire to ensure that the vehicle does
not move.
3) Install a ramp between the transport vehicle and the machine. Make sure that the ramps on both
sides are on the same level. Make the slope of the ramp is no more than 15 degrees. Adjust the
distance between the ramps to match the center of the track.
4) Remove the wire rope that secures the machine.
5) Start the engine. In winter, the warm-up operation should be carried out thoroughly.
6) Put down the left control box.
7) Lift the stick and bucket, and raise the bulldozer shovel.
8) Check that there are no obstacles in the excavator's range of activity.
9) Pull up the platform lock pin, make the platform rotate 180 degrees, the excavator faces the slope,
and the excavator is in the forward direction.
10) The excavator advances slowly until the top of the slab, and the stick is extended to make the
excavator track tilt down onto the ramp, and then slowly advance to the ground.
5. Hoisting the machine
A. Safety precautions
1) Do not hoist the machine when there are people on the machine.
2) Ensure that the steel wire rope used for hoisting the machine has sufficient strength to bear the
weight of the machine.
3) Except for the postures provided in the following procedures, do not hoist the machine in any
posture, otherwise, the machine will lose its balance.
4) Do not lift the machine when the upper structure is turned to the side. Turn the platform before
hoisting so that the working device is in the same direction as the bulldozer shovel and the lower
track is parallel to the upper structure.
5) When raising, keep the machine level.
6) When hoisting the machine, it is dangerous to walk under the machine. Do not walk around under
the machine.
B. Hoisting procedures - for machines with standard technical specifications
Note: The hoisting procedure is applicable to machines with standard technical specifications. The spreader
should be a special spreader with a lifting capacity that meets the weight of the machine.
Follow the below steps to lift the machine for those with lifting holes. (As shown on the right):
