1. First check if the bottom dead point contact switch is in good condition;
2. Whether the hydraulic oil tank is short of oil (after the hydraulic pump enters the air, it will cause damage to the oil pump or fail to reach the working hydraulic pressure);
3. Check whether the hydraulic oil pump is in good condition (the hydraulic pump of the sawing machine that has been used for a long time may not reach the hydraulic pressure required for work after it is worn out);
4. Check and adjust the overflow valve to restore the working hydraulic pressure to normal
5. Check whether the solenoid valve and hydraulic pipeline are leaking;
6. Check whether the lifting hydraulic cylinder is damaged (rarely damaged);
