Fault 1. The machine is not working, but the pump is still running
Reasons: 1. The rotation direction of the motor is reversed;
2. The motor is connected into a single phase;
3. The voltage of the Magda terminal is too low;
4. The hose of hydraulic pipeline leaks or is caught;
5. The pump coupling keyway leaves the pump shaft;
6. Liquid level in the tank, correct if necessary;
7. The suction filter of the oil tank or the ventilation cover at the top is blocked;
8. The suction pipeline device is loose and the suction port of the pump has capillary cracks;
9. The solenoid is activated;
10. The hydraulic pump is broken.
Problem 2: the machine is running too slowly
Causes: 1. Something is blocking the suction filter, ventilation cover or pressure filter, or the hose is caught;
2. Motor voltage is low;
3. Thin or thick oil
Fault 3: motor overheating
Reasons: 1. The voltage is too low;
2. Adjusted working pressure is too high
3. Wiring error;
4. Pump overheating due to lack of oil;
5. The oil is too thin or too thick;
Fault 4: oil leakage or oil spraying from the oil tank
Cause: the air vent block causes the tank pressure to increase, causing the oil to spray out. Clean the vent hole or change the vent device.
Problem five: the machine can 't work, the motor can' t work
Cause: 1. The control fuse is blown;
2. Motor starter overload off.
3. Lead fuse is blown, single-phase motor and disconnected motor starter are overloaded;
4. The transformer has problems;
5. Problem with button
