Electric Power & Utilities/Table saw 1Hp motor sears


I have a sears table saw motor model 113.1247 . When it's plugged into electric the motor starts and shakes and then blows the circuit won't stay running and shakes a lot any help or answers ? Thank u!

First,unplug the saw, then take a air hose and blow out the motor. Sometimes dust can get between the points of the start switch. If that is not the problem, then you must check the start capacitor. Look for signs of cracking, or a bulge in the hole at the connectors. Most electric repair shops may test it for free. Anything beyond this may require dis-assembly of the motor. This should be done by a service center.
