Movement of the machine
1. Safety principles for moving machines
1) Before starting the excavator, you should be familiar with the surrounding environment of the site, whether there are
pedestrians, obstacles, and ground-bearing capacity.
2) Sound the horn before starting the excavator to warn others to pay attention.
3) Drivers are strictly prohibited from standing on the ground to start and operate the machine.
4) The excavator must walk and work on solid ground with a width greater than 1.5 times.
5) When walking through underground passages, bridges, or under high-voltage power lines, be sure to have gesture
commands.
6) When walking, the boom and stick must be lowered to maintain the best position of the center of gravity.
7) When walking, only the driver is allowed to drive on the machine and no others are allowed.
8) Before operating the steering joystick, check the direction of the crawler frame.
9) If the bulldozer shovel is behind, the operation of the walking joystick is reversed.
10) Don't let anyone in the area around the machine.
11) Remove all obstacles on the walking route of the machine.
12) The rear of the machine is a blind zone, so pay special attention when reversing.
Warning: It is dangerous to change the joystick suddenly when walking at high speed.
1) Don't change the joystick suddenly, otherwise, it will cause a sudden start.
2) Avoid suddenly changing the joystick from forward to backward (or from backward to
forward).
3) Avoid sudden changing of the joystick, such as a sudden stop from high speed (release
the joystick).
2. Preparation for moving the machine
1) Put down the platform lock pin to lock the
platform rotation.
2) Turn the throttle handle to the high-speed
position to increase the engine speed.
