Hello all,
I’m after your friendly professional opinion here, I’ve recenty bought a Makita LS1018l Compound Mitre Saw, as recent as a week ago to be exact.
the saw has had about 20 mins total run time since I’ve had, from new.
I was cutting widths on a 4×4 yesterday to cut out a mortise and had it running for around 3 minutes off and on, off and on for around 10 seconds each time and smoke appeared out of the motor vents and it stunk. Now it won’t turn back on, even after cooling down as that was my initial thought, so I checked out the brushes and they look like this.
do I need new brushes or is it something more serious?
Thanks and sorry for the long rant over something very basic but I’m fairly new to this type of power tool and after only a weeks use this seems fairly odd
You might be on to something. That one brush looks pretty nasty. You have a side view of the other brush. Is the surface just as bad? If not, you may have a brush holder problem, where that nasty looking brush is not making good contact with the armature. Examine the commutator (where the brushes touch) and see if it is burned up. Hopefully it is not a shorted armature. I have had to replace a brush holder on vacuum for a similar problem. The overall wear on those brushes is not excessive so the cause of the oroblem is not normal brush wear.

Thank you for informative reply!
The middle picture (the one on the piece of timber) is the other brush, pretty clean other than the burnt wires which I’m guessing is a sign of wear.
I have ordered new brushes to see it solves it but I’m not holding much hope so in which case I’ll contact Makita to repair!
