Precautions for working at the excavator exit position:
(1) Never perform any maintenance on the machine without properly supporting it.
(2) Lower the working device to the ground before repairing and maintaining the machine.
(3) If it is necessary to lift the machine or working device for maintenance, use pads or brackets with sufficient strength to support the working device and its weight to firmly support the machine or working device. Do not use slag bricks, hollow tires, or racks to support the machine; Do not use a single jack to support the machine.
(4) If the track shoe leaves the ground and the machine is only supported by the working device, working under the machine is very dangerous. If the hydraulic pipeline is damaged or accidentally touches the control rod, the working device or machine will suddenly fall, which can cause casualties. Therefore, if the machine is not firmly supported by pads or brackets, do not work under the machine.
