1. Do not suddenly push the lift handle to the "down" position while fully loaded.
If this operation error occurs, the vehicle body will suddenly drop, causing significant impact force on the vehicle frame and even causing an accident. Therefore, avoid this operation as much as possible. If necessary, operate with caution and slow down the lowering speed as much as possible. Never suddenly lower the vehicle body to the bottom.
2. Do not use sudden lifts or sudden braking to unload cargo.
Due to the significant inertial force of sudden lifts (typically 5 to 20 times the rated lift capacity), this can easily cause permanent deformation of the vehicle frame, weld separation between the vehicle body and auxiliary frame, burn out the fuel pump, damage seals, and damage to the hydraulic cylinder. This can shorten the vehicle's service life and, in severe cases, may even cause a rollover. Therefore, it is generally forbidden to operate a dump truck while it is lifted.
3. After unloading, the power take-off must be disengaged before driving the dump truck. If this operating error occurs, while the dump truck is driving, the lift pump will operate at high speed and without load for an extended period in a "small circulation" mode because the power take-off is in the "engaged" position. This causes the hydraulic oil temperature to rise rapidly, potentially damaging the pump seal or even causing the pump to burn out. More seriously, the operation of the pump indicates that the hydraulic system is powered, making it easy for the vehicle's cabin to automatically lift while driving.
4. The power take-off should never be in the "on" position while driving.
If it is in the "on" position (red light on), the pump will continue to operate, providing power to the hydraulic system. This could cause the cabin to automatically lift due to an incorrect operation of the air control valve. Even with the air control valve in the "down" position, oil will still enter the pump, potentially burning it out.
