Table saw issue - run capacitor?

[Farm Labourer]

I was running my table saw today. Stopped it, adjusted the depth of cut and pressed the green button on the NVR. It span up but as soon as I released the button when unit at full speed, it died.

I think it's probably the run capacitor but just wanted to check with the learned on here. 240V 1Ph.

TIA

Did you have to hold the on button till the blade reached full speed every time you used it ?

The run cap keeps the auxiliary (“start”) winding in play to improve torque. A bad one shouldn’t prevent the motor from spinning.

Sounds more like your starter switch is not holding ‘on’. It’s not normal to have to hold it on until the motor is at speed.

What happens when you press ‘on’ now?

My thoughts too guineafowl , Faulty switch is a fair guess without any more information to go on.

Did it over heat, were you working it hard.

Mine will do that if worked hard, but returns to normal when allowed to cool down.

This is a typical starter. When you press the START button, contactor M is energised and one of it's contacts (in this case M wires 2 and 3) closes which allows you to release your finger on the START button, it's called a "retaining contact". In your case it sounds like the retaining contact is faulty.

I've had this on my Kity 619 and it was the NVR switch

Thank you one and all - it was the thermal overload on the switch - runs like a deer again!

Hi Farm/L,
Just last week my Scheppack planer decided to simply "purr" and not start. I rang Power Tool Spares and spoke to Alex, he suggested it was likely the capacitor and send him a photo. He didn't have one in stock but ordered one to come direct. This all happened within hours, I was soon up and running again.
I post this (from just south of you) in recommendation of [email protected] to anyone looking for friendly affordable help.
