blade brake not working 1/2 the time on Hitachi C1 - d70d03f.jpg38ca9blade brake not working 1/2 the time on Hitachi C1 - 1add57c.jpgss=4367374.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

My hitachi miter saw started to buzz when plugged in. It's seems to work normal when trigger is pulled but starts to smoke when I release the trigger. Bushing poor good. I have no idea what is wrong?


have it investigated by an appliance repair shop
the system is this
plug in --no noise
pull trigger -- blade spins and makes running noise
release trigger and blade stops -- no noise
anything else indicates a serious problem with the unit especially if it is smoking.

Hitachi c12rsh brake


There are a few things that can cause this:
1) Check the brushes - make sure they are not severely worn and make sure they travel freely down the brush tube & contact the armature well.
2) If the brushes are OK the problem is most likely the switch. Tools with a brake have a 2 pole switch - one set will be normally open and one set will be normally closed (Most switches have a diagram printed on them) Disconnect the leads (keeping track of where you removed them) and using a continuity tester check the switch - you should get a reading between the normally closed contacts and lose it when you pull the trigger. Most likely you will find you are not getting a reading on the normally closed side and that would be your culprit. Hitachi C12RSH 12 Sliding Dual Compound Miter Saw Parts

The laser stopped working on Hitachi 12'dual compund mitr saw,are there batteries that can be replaced or does the unit need to go to a tech? The laser only worked for a month and the saw is only 3 months...


The laser modules in saws are usually powered by induction from the spinning saw blade. Since your saw is only three months old hopefully you either registered it with Hitachi when you bought it or you still have your receipt as this type of failure would be covered under warranty. Call Hitachi, they may send the part to you if you are comfortable with doing the repair or they will tell you where the nearest Authorized Service Center is for warranty work. Hitachi's number is: 800-706-7337 or 770-925-1774.

How to change the blade?


I don't know if this will help you much but I've got a DeWalt 14 inch chop saw and a 10 inch miter saw and they both have a small lever on the right hand side of frame just behind blade If you depress this lever and slowly rotate blade until it drops into place this locks the blade for changing. Hope this helps you. Thanks.

Does Hitachi C12FCH cut Aluminium?


Hello. A muli-answer for this I'm afraid. The quick answer is yes depending.

Depending On:
  • Thickness of material
  • type of blade
If you are simply wanting to cut aluminum siding/soffit, then install a paneling blade backwards and chop down slowly

If you are referring to bar stock, you will - but not well. You will need a special quick-cut abrasive blade, and you may find you need to change the blades often.

If you wish to cut screen door trim, curtain rod, draft stop, Jolie Edging for ceramic tile, or other thin hollow/extruded materials - then the abrasive blade will do nicely for short/small jobs.

The main problem with cutting aluminum in a high speed rotary device is that the friction of the blade heats the metal fast enough that you get a coating on/in the blade. (In layman's terms - bunged up) The devices in machine shops are set considerably slower, and are usually cooled mainly with liquid.

Hope this answers your question satisfactorily. Good Luck and don't forget to rate this answer.

Thank You,
Richard
