Solution for "changing blades on a milwaukee miter saw

Just a thought; maybe your saw requires a 300 mm blade rather than a 12 inch?

The popular view is the two sizes are interchangeable but there is a small difference in diameter with the Imperial blade being about a quarter inch bigger than the metric.

I had a similar problem with an eight inch saw. When I fitted an eight inch blade it seemed to be ok but when switched on it made a loud noise, similar to yours I guess.
I was unwilling to buy another blade so I modified the saw to give the blade housing a little more clearance so I could use the eight inch.

Try clockwise.
unscrew the blade clockwise.

unplug the saw/remove battery
press the button on the side near the blade
pull old blade out. push new blade in, release button to lock new blade in place.

See page 9 of this manual: http://documents.milwaukeetool.com/58-14-6955d3.pdf.

The manual is for a 12 inch saw, but the instructions will be similar. UNPLUG THE SAW FIRST!

Hi, you need to look thoroughly at the casing of the electric motor. Somewhere between the motor and the gearbox is the brake which must be depressed in order to stop the motor from turning. If for some reason you cannot find this brake, use a pair of vise grips and clamp down on the inside of the blade and turn it until it stops. Now you can unbolt you blade. P.S. make sure you know if the thread is reverse or not! Good luck.

Un-plug the saw. Remove the screws holding the side saw guard in place. Look at the center of the saw blade for the nut holding it in place. Take a socket wrench that fits the nut and loosen it. You'll need to take a scrap piece of wood 2x4, and jamb the teeth of the blade into it while loosening the nut. The nut will come off first and then a washer/spacer.

Reverse the order for installing the new blade. Make sure you use the proper size diameter blade (10 inch) and mounting hole in the replacement blade. Also, use the provided washer/spacers that were on the original blade and secure the nut. Spin by hand to see if everything clears. Mount the protective guard back on. Plug in the saw and test cut .

Good luck. If you are still unsure - ask a handy neighbor to help. It takes about 5 minutes to complete this task.

I would suggest going to Milwaukeetool.com and typing in your model number and pulling up a wiring schematic for this tool. If your switch and field are not as shown on this breakdown (its a good one) I would either take it to a repair center or change what is wrong one wire at a time. They also have a toll free number and would be more than willing to help with your problem. Let me know and have a good day. P.S. I would not run the blade backwards though.

I'd say it was the new wiring that was reversed. Motors cant really start reversing themselves on their own and the only other way it would seem reversed is if the blade was put on backwards...

So yes I think you have the wires reversed when you re-wired the cord.

older model of circular saw dont have a spindle lock.wedge the blade on a bench vise & make sure ur not clamping the teeth of the blade & then turn the blade screw clock wise.

If you haven't fixed them yet, give me the model and brand and I will see what I can do. Dave
