I'll preface this by saying that most electrical stuff, other than a very basic switch, is Greek to me.
I recently bought a nice little Jet precision drill press. When I plug it in, the motor starts running but won't turn off with the variable speed control even when put into the Off position as the manual says it should.
The power switching is a bit more complicated than your average setup. It has a variable speed control, a light, and a micro-switch. According to the limited description available in the manual, when the speed control knob is turned ON, " a detented click will have been heard as the motor stand-by switch is actuated." That doesn't happen. I can push on the micro switch button and the motor stops but it's not practical to hold it for any more than a few seconds.
Also, there is a phrase in the manual that says "Quill actuation lever... It's operation is for lowering and raising the quill and actuating the spindle motor as the quill is lowered.. This is accomplished by mechanically linking the quill actuation lever with control panel micro switch operation."
So, my questions are :
- are there any obvious solutions such as just replacing the micro switch.
- Or, will it require testing the switch, variable speed control, or the various resistors and capacitors ?
- Maybe a switch hidden inside at the quill to trigger the micro switch ?
