After the power is switched on, the power indicator is on, first put the workpiece into the frame port, switch the working mode to the manual position, the demagnetization work starts, the demagnetization indicator is on, stay for about 5 seconds, slowly move the workpiece out of the frame port, and then switch back to the stop or automatic position, after a delay of 6 seconds, the demagnetization automatically stops working, and the demagnetization indicator is off. Before the demagnetizer stops working, the workpiece must be moved out of the frame port and moved in the horizontal direction to a place 1.5 meters away from the demagnetizer, in order to produce a gradually weakening alternating degenerating magnetic field inside the workpiece itself. The working mode switch is in the manual position and can also be powered on for a long time.

1. Press the operating button of the grinding wheel motor to start the switch of the electric permanent magnet chuck. Note: the workpiece cannot be drawn, the contact of the relay is interlocked, and the grinding wheel motor cannot be started. 2, open the special distribution box of the machine tool, use the measuring pen to detect whether there is electricity at both ends of the fuse, and then use the multimeter 500V to measure the power supply voltage to 380V.
