Some Fault Solutions For Automatic Cutting Machine

- Feb 23, 2021-

1. Indicator light is not on: the whole machine has no power

2. Transformer insurance burned out: replace the fuse

3. Brake switch not on: turn on the power brake switch

4. If the indicator light is not on, it can start the motor: the indicator bulb is burned out and the indicator bulb is replaced

5. The indicator light can not start the motor

(1) Motor protection switch switch: open the motor protection switch

(2) the main control contactor is bad or burned: replace the contactor

(3) motor burning: replace the motor

6. Indicator light can start the motor but can not work

(1) the cutter die setting switch is hit to the horizontal position to lock the oil circuit: the cutter die setting switch is hit to the straight direction

(2) Motor steering error: the two phase lines of the motor are exchanged and connected well

(3) the work switch contact bad wire off: check the line connected to the wire

(4) solenoid valve coil burned out: replace the coil or the entire solenoid valve

(5) Solenoid valve spool stuck: cleaning the valve spool

(6) Loose stroke adjusting handle: reset the cutter die

7. Unable to work can be reset: the circuit board in the electrical box burned out to replace the circuit board

8. Working but not reset: the circuit board in the electrical box is burned and replaced

9. Not being stressed at work

(1) cutting material layer is too thick: reduce the material layer

(2) the setting stroke of the cutter die is set too low: adjust to the appropriate position

(3) filter blockage: clean or replace the filter

(4) Oil pump damage: replace the oil pump

10. Oil spills

(1) cylinder oil seal aging: replace the oil seal

(2) the high pressure oil pipe joint is loose: tighten the joint

11. Noise from motor oil pump

(1) the oil pump rotates the rubber wear: replace the rubber

(2) filter clogging: cleaning the filter

(3) Hydraulic oil loss: add enough hydraulic oil

(4) oil pump bearing damage: replace the bearing

(5) The oil seal at the shaft end of the oil pump is aging: replace the oil seal

(6) Motor bearing damage: replace the bearing

12. Slow down and crash after lowering or rising, unable to rise or fall

(1) cylinder sealing ring aging: replace the sealing ring

(2) the solenoid valve core is seriously worn: replace the solenoid valve

(3) reduce the viscosity of pressure oil: replace the pressure oil

(4) board contact is bad: check the line

(5) the main road can not be switched: check the line

(6) solenoid valve stuck: wash the valve body
