Point one: switch damage
Switch accessories damage is extremely vulnerable to stop running the machine, it is because the switch button won't damage will occur after contact, also is the condition of the circuit impassability, this kind of circumstance only need to use a multimeter to check when you can confirm whether arising from a switch, and then directly replace the new switch.
Point 2: pump damage or too little oil
The hydraulic oil level in the hydraulic pump of the rocker arm cutting machine must be higher than three centimeters above the filtration level. After the determination, the hydraulic oil in the oil pump can be seen to circulate in the mailbox after starting up, otherwise the oil pump must be checked to see if it is normal.

Point 3: motor inversion
Motor reversal is the important factor of radial cutting machine malfunction, the motor rotation direction should be consistent with the steering mark, if there are no words to mark on mechanical, cooling fan, can be observed under normal circumstances should be clockwise, if developed motor steering is wrong, then you can switch any two root of three-phase power supply cord.
Fourth point: tubing or universal joint off
The tubing and universal joint is used to connect the oil line integration block and the oil cylinder. If it falls off, the hydraulic oil cannot enter the oil cylinder, and the rocker arm cutting machine cannot move naturally
Fifth point: cylinder seal ring off or damaged
Open the oil tank cover to see, the oil cylinder seal ring should be placed in good condition inside the oil cylinder (outside can not see), if see the seal ring, prove that the oil cylinder seal ring has fallen off, the reason is: rocker arm rise too high (this situation is more).
The sixth point: solenoid valve damage or no power
Solenoid valve for action components, damaged or stuck, rocker arm cutting machine can not move.
