My 12 inch Dewalt Miter saw is acting up. Sometimes,
the brake doesn't engage right away, and sometimes, it
doesn't start when I pull the trigger. (I have to move
the blade up and down a few times before it will engage.)
Is this a simple fix, or should I be worried?
Yeah, I did that. I haven't changed the brushes, but the saw
is only a couple of years old. Also, I don't know if the brushes
would be the reason the brake doesn't engage right away.
Thanks to the other poster too for their info.
Since both issues point towards the switch, instead of spending a lot of
time diagnosing, pay $14 for a new switch and put it in. It took me all of
5 minutes on a job site.
Sounds to me like either the brushes are worn out or the commutator or
armature has a problem. The brake depends on having good contact between the
brushes and commutator. A worn commutator would also cause the starting
issue since you have to turn the blade sometimes in order to get it to start
Check the brushes first, then look down inside the brushholder with a
flashlight. All of the copper segments should look identical (uniform black
tracking is normal). Also, the gaps between the copper segments should be
identical in width. If one of the gaps looks a little wider and rough at the
edges, then you need a new armature.
