Quoted from moonwk:I got a used hakko 472d. The heating element works fine but the air pump doesn’t turn on when I push the 808 hand piece button. I changed all the filters. When I give power to the pump it does suck air. So I’m guessing it’s the hand piece or the board. Can someone send me pictures of the wiring of the hand piece? Any other suggestions would be much appreciated.
Thank you
The 808 gun only has 4 wires. 2 are for the heating element and 2 are for the switch.
