Record 300 bandsaw working well then slowed and stopped. Blade has free movement,not damaged. Is it the motor? It did take a few seconds to get upto speed before it died. Any ideas?

I reckon it is the motor, try taking the blade off and trying it again, feel for any roughness when you turn the lower wheel by hand and have good sniff for any burning from the windings.

record have a five year guarantee and you should find the build date on the machine somewhere, do not worry if you bought it second hand as the guarantee is for the machine

It is usually the motors capacitor that blows, it will usually be under a cover attached to the motor, note its values and replace (usually around £10-£15uk pound), nine times out of ten it's the capacitor that blows.

Good luck, feel free to contact me for further information.

Thanks Ron &Ryan. No problems when turning lower wheel and unfortunately the bandsaw is well over 5years old. The capacitor sounds like a likely candidate though. I will get that checked out tomorrow.

Hi Gary, Not sure how competent you are with this kind of machinery but if you are not then don't attempt it. If you remove the blade and switch on you can give the motor a tweak it should run up, if it does then the problem could be the startup capacitor. You may need to over ride the safety switch to do this which is why I would ask about your knowledge of maintenance, if you don't use a safe method it could be dangerous. As I say if this is not your area of comfort then don't attempt it. -- Julian

Hi Julian, Thank you for your health & safety input. As you probably read at the beginning of this saga the motor is dead, it doesn't work. There was no chance of danger.

I must take this opportunity to thank all the contributors, Ron, Ryan, Sad Sam and Julian, most helpful.

I took the motor to a specialist ... The diagnosis was that the thermal cut out within the winding had done its job and burnt out (this can be easily replaced, by people who know what they are doing, on this model without having the motor re-wound) and the capacitor was also duly fried. Both replaced by the pros at

SpinneyRewinds Ltd (spinneyrewinds.com). Excellent service at this family firm.

Motor now works thanks for all your help

Gary
