10yr old table saw smells hot and trips breaker


Maybe, but first rule out several other things. Has the saw been recently overloaded - heavy cuts with a dull blade? You may have a partially burnt-out motor (which means the insulation on the wire in the windings has partially melted.) Has it been used recently or used now with an extension cord or to an outlet wired with 15 ga wire? Is the saw arbor hard to turn by hand (with the belt removed)? Does the motor overheat with no load (remove the belt and let it run for 10 minutes)? Try running the saw with the belt on, but not cutting for 10 minutes.
Good luck!

Our Easy-Flo built in vacuum system will not turn off, even when the hose is disconnected. We have to turn it off manually. Could it be a short in one of the wall outlets causing this?


Some models have an on/off switch on the power unit itself. This switch is used to turn your power unit on when you are right at the machine.
If there is no switch on the power unit, unplug your power unit from the wall socket, look for two low voltage wires coming out of the power unit. These two low voltage wires are usually either attached with terminals or are tied to two wires coming out with plastic screw on wire caps. Disconnect the 2 low voltage wires. Plug your power unit back in. If the power unit does not come back on then yes, the problem is most likely a short in the outlet wiring. If the power unit still comes on with the 2 low voltage wires unattached, then the problem is in the internal circuitry of the power unit, usually a relay or some units have a circuit board with relay, circuit breaker and other components on it. The relay or circuit board will have to be replaced.
It's a little difficult to check for a short if you have multiple outlets, but if you've recently done some renovations you might start checking in that area.

Unit has power from Plug to unit. Current flows all the way to switch and switch seems to be ok but unit will not turn on. Wife says it was cutting on and off when moving it around. Checked conntec


you either have a bad switch oir you have a short in the cord.plug it in and turn it on then move the cord around from top to bottom and see if it acts up..if not tap on the switch afew times and if it cuts out then the switch is bad.try to plug it in in a couple of different outlets and see if it does the same thing.it could be a bad outlet.plug it in one thats pretty tight to push in and pull out.
