I have a co-worker who needs to join lj’s but until he does I thought I’d ask a question on his behalf. He has a 2002 Skilsaw 3400 15 amp saw that seems to have a motor issue as in “sometimes it works and sometimes it doesn’t”. He knows it’s a cheap saw but he has mainly been a carver up until now so it worked for him. My first thought is brushes. He’s in the process of searching for a saw upgrade but was wondering if anybody had any ideas on what the issue could be in the mean time. (Other than he needs a new saw)

Take a look at the right side of the number shown in your pic that says “F0123400…”, and find the rest of the number/letter sequence so you can determine exactly what type model 3400 he has. Then go to this link and find the correct brushes and their location. Carbon Brush Set Part Number: 2610909439

It could just be saw dust in the switch.

Faulty switch, which is fairly common on the cheaper low end stuff. Could be brushes, but those are easy to check and usually when they fail, it won’t be intermittent.

Agree on the switch. He can test it by removing it and just putting a meter across the leads on the ohm scale. If the meter peaks when it’s switched on it’s good, if not it’s bad.

Have your say...
