What are the reasons why the rocker arm cutting machine does work?
Solenoid valve
1. Damage lack of power;

The solenoid valve is an action performance component. If it is damaged stuck at the back, the rocker arm cutting machine cannot move.
2. The button switch is damaged;
The button switch of the rocker arm cutting machine is a consumable part. When the contact is in good contact, the control circuit cannot be connected. At this time, we should replace it in time. Generally, a multimeter can be used to detect whether the button switch is good bad.
3. There is less oil the oil pump is damaged;
The position of the hydraulic oil should be more than three centimeters higher than the filter. At the same time; after starting the machine, the hydraulic oil should be seen to be circulating in the oil tank. Otherwise, it should be checked whether the oil pump system is normal.
4. The oil pipe universal joint is lowered;
The oil circuit integrated block the oil cylinder are connected by oil pipes universal joints. If the oil drips, the hydraulic oil cannot enter the oil cylinder, the rocker arm cutting machine cannot move naturally.
5. The motor is reversed;
The steering motor should be marked together when turning on. It should be noted that if there is no steering investigation steering cooling fan (clockwise), right steering, to exchange any two three-phase power lines.
6. The oil cylinder seal ring has fallen off is damaged;
Open the oil tank cover to check, the oil cylinder seal ring should be intact inside the oil cylinder ( visible the outside). If the seal ring is seen, it proves that the oil cylinder seal ring has fallen off. The reason is: the rocker arm is raised too high (this situation is more common).
