Knowing what saw we are talking about (and thus, the type of motor) would be extremely helpful. Otherwise, I’d say to make sure the tires are pumped up to 32psi, check the oil and ensure you are using fresh gas.

Cheers,

The answer likely depends on the type of motor…induction (quiet) or universal (loud). If you’re not sure, tell us the make and model, or maybe take some pics of the saw.

Could be a bad capacitor….easy and cheap to fix if so. Your motor should have one or two “cans” poking out the side. Remove the cover(s) and see if there’s any visible damage (bloating, black, ooze, etc), and/or check the caps with a meter to see if they’re still good.

Not sure what kind of switch is has, but I recently had my TS run like it was low on power and then finally quit. In my case, the switch contacts had apparently had some arcing and one of them was only making partial contact, reducing the current flow to the motor.

You might hotwire around your switch and see if you have the same issue.

Thanks for the replies everyone. I figured out the problem and it was nothing electrical.
I noticed the pulley was backing off the shaft a little. Come to find out the key holding the pulley to the shaft had fallen out and was making the pulley slip on the shaft a little. Luckily the key had landed next to a pile of sawdust and not in it so it was easy to find!

Have your say...
