Electric shocks from scroll saw

When I run my scroll saw, and touch the saw table or arm, I get a small electric shock. This does not happen when the saw is not running, so I have ruled out static. What could be causing this? The saw is a ryobi, about 2 years old. Help would be much appreciated.

It sounds like a wire is rubbing some where on the inside of the machine when its running. If you say its a small shock its probably a neutral wire.

#1 Unplug the saw. #2 Unplug the saw. #3 Lastly, inspect, clean/brush off every electrical connection that you can find from where the power cord enters the machine. Just motor and switch, should not be too many. Probably nuts +/- lock washers on threaded posts with the wires terminated in spade connectors.

Does the machine have a 3 prong plug and is the ground prong intact? If everything checks out and it still does this check the outlet you have it plugged in to for swapped hot and neutral wires and/or disconnected grounding wires in the box. It could also be a sign of a short in the motor windings.

Great advice from previous posts, but also consider contacting a Ryobi service center for their input & repair ideas. Be safe.

That would be my first choice, it is a safety issue and I doubt they want any bad publicity so they may be happy to do something, particularly if it is a know issue.

There are unwritten, unpublished warranties on a lot of products, not only tools but autos as well.

it is a short somewhere. if you are not electrically inclined, find a friend who is. dealer may charge because of age (but try first), and it should be easy to find, there are not a lot of electrical components on it.

I would not use it until this problem is solved.

plug it into a gfci protected circuit, to see if it trips.
