Safety precautions for both busy engines after starting and during operation:

① After the two busy engines start, wait for the brake pressure to reach a safe pressure before preparing to start, to ensure braking safety during driving. For those with emergency braking, press the buttons on the emergency and parking brake valves to release the emergency parking brake before shifting to I gear to start. For those without emergency braking, simply put down the parking brake handle and release the parking brake to start.

② Clear the faulty objects busy on the road at both ends, paying special attention to obstacles such as iron blocks and ditches to avoid cutting the tires.

③ Adjust the rearview mirror to provide the driver with the best view after sitting.

④ Ensure that the busy horns, reverse signal lights, and all safety devices at both ends are functioning properly.

⑤ When about to start or when checking the flexibility of turning left and right, the horn should be sounded first to warn surrounding personnel to pay attention to safety.

⑥ Before starting to walk, all control handles, pedals, and steering wheels at both ends should be tested first to ensure that they are in a normal state before starting work. Pay special attention to checking whether the steering and braking are intact. Ensure that the steering and braking are completely normal before starting and running.

⑦ When both ends are busy moving, place the bucket at a height of about 400mm above the ground. When working on slopes in mountainous areas or crossing obstacles such as ditches, slow down, turn small corners, and avoid tipping over. When the loading surface begins to slide to one side on a steep slope, it must be immediately unloaded to prevent further sliding.
