Recently my very trusted garden trimmer stopped working and the troubleshooting was a mess on that one, which made me think, when was the last time I checked the motors on my other power tools?
I used to do it every now and then but didn’t get to it for quite some time.
So I decided to pull out my Milwaukee Circular Saw and give the motor a quick check, it has been working alright and never gave me much of an issue but I still thought a bit of testing never hurts for precaution.
But before you continue reading this article, you may first watch the short YouTube video about this topic. You can watch it below.
On the video, I removed the casing of the Milwaukee Circular Saw. To test the condition of motor, I connected the motor directly to the battery. If the motor spin with a direct power supply, it means it’s working fine.
Milwaukee Circular Saw Motor Testing: Step-by-Step Guide
If you are behind on the maintenance of your power tools or trying to do a quick test on yours too, here’s how I did it.
Remove the battery and blade
The first thing I did in order to test the motor of my Milwaukee Circular saw is take safety precautions.
To do that, I started by removing the battery from the case by gently clicking it out of the place, then I got to take the blade off, which is held in place by a metal bolt.
With tools like this, I always start by removing the power source as a little press of the trigger can cause a big accident.
Remove the motor casing
Once the battery was out, it was time to remove the casing which I did by first taking out the screws from the handle, grip and the motor cover.
From there, I just gently pushed the head of my flat screwdriver in the narrow opening of the body to shimmy it open, with just a little twist the red body came right out.
Just a reminder, make sure you keep an eye on the screws, those little things tend to run away and get lost.
Test the motor
With the casing off, all that was left was to check if the motor works alright. To do that, I took the battery out to directly connect the motor to the battery using jumper wires, positive to positive negative to negative.
It made the motor spin perfectly confirming that the motor is well and running with no hesitation, it also made some sparks, which is common when testing with a high voltage battery but make sure you glove up and test the motor in short intervals only.
Once tested, I put the casing back on and clicked the battery and blade in place to check the saw with a wooden dowel and as expected, it did a wonderful job sawing the wood in half.
