The brake is constantly on. How do I release on 12" dewalt miter saw


A very much high priority specially on the bearing of the motor on the side where the flat belt is driving the saw on. control it the sawblade should have no problem to turn
There is an electrical brake for a short time after release the switch build in the electric field but it has not an electrical-magnet brake like the DW701 miter saw that only released by an electrical activation.
In high priority this should your trouble i think . 1 order number its a 6302V BALL BEARING or equivalent brand can be replaced by your dealer.

Dewallt have many problems on the choosen fan have to short blades and if the fan is melting because of the heat by to long wait for replace then there is only a complete new armature to buy

Ryobi 10 in Mitre saw with laser, switch / motor wiring diagram?


capacitors are known as capacitors or condensers. Both do the same job of storing electrical energy and then releasing it when the current flows back . They are used to either start an electric motor or stop arcing on the brushes by absorbing the current flow as it stops over each commuter bar of the armature

Where is the blade brake on the miter saw


The brake on electric motor driven tools is the field & armature. When running the switch provides power to both sides/poles of the field through the brushes and armature. When you release the switch half of the field is powered pulling the armature to a stop. If your bladed continues to spin when the switch is released, you need to replace the switch. The Ridgid part number for the proper switch is 503317000.

I have an older model black and decker miter saw. How do you change the blade? I can't seem to stop the motor shaft from turning in order to loosen the nut to remove the blade?


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.

How do you change the brushes


You have two, 1/2 inch flat head screw things on the right side of the motor, pull them out, the carbon should be at least 1/4 inch long, min, brushes can be bought at the hardware store. The electric brakes on those saws eat them brushes up. Check it out.

Intermittent miter saw


In order of cost, for the likely problem.

Inspect the brushes to make sure that they are making good contact with the armature, this would make it run intermittently and are the most common and cheapest. Next would be the thumb switch, it reverses the polarity momentarily and causes the motor to brake. These are the most common reasons it won't run, especially if the brake is not working or being intermittent, the switch is the problem; and if this doesn't fix it, then I'd try the controller.

Hope this helps, if so, mark my answer please so I know if I've helped or not.

I have a Hitachi C8FB2 compound miter saw that the electrical break has stopped working on. The bushings are still good but I see and hear a electrical arc were the bushings touch the shaft. What can I do...


there is always going to be some sparking between the BRUSHES and the commutator. if it is excessive and loud or is really heating up the housing, there could be a crack in one of the brushes, the brush might be chipped or unevenly worn, or the brush holder itself may be burned cracked, or otherwise need to be replaced. they may LOOK okay but need to be pulled out to really know for sure sometimes. there is a small set screw in the housing that holds the brushholder in place.

while this could be the problem with the electric brake, it is more likely that there is a wiring connection loose, broken or burned inside the motor housing. it could be the switch but i dont believe the brake circuit runs through the switch on this model.

Blade brake not working 1/2 the time on Hitachi C15FB chop saw


d70d03f.jpg3f82e5b.jpg38ca90b.jpg4367374.jpg063ef2e.jpg1add57c.jpg98eea3c.jpg The first picture is the only one I could find of your saw.
All saws are fitted with carbon bushes that contact the armature of the electric motor.
In time the carbon which conducts the electricity wears down, as they disintegrate there are particles of broken carbon connect with the armature giving an intermittent burst of power, eventually the bushes no longer contact the armature and the saw does not work at all.
The next photos show the approximate position of the cover to access the bushes, there is one one each side of the housing.

They usually unscrew and expose the spring plate the bush is mounted on, gently pull this out.
As you can see the bush is worn in a concave shape, and that the wide side is breaking up.
If this is your problem then take the bush and model number of your saw to a supplier or spare parts shop or the hitachi web site to get replacements.
Hope this helps.
If anyone finds this information helpful please tell fixya
Cheers
Les
