These machines have an induction motor and need a capacitor to give it a kick start. Is it humming when you push the button? If so I would check the capacitor and you will probably find the fault there. Otherwise it could be a problem with the table switches. When the table is flipped it pressesd against a button which tgells it which on switch is operational. If something has blown there it would disable both buttons.

Dewalt saw blade won't stop when I off the trigger. How to clean the communicator?


This problem can be caused by the brushes wearing out. Check brushes first. If you need to clean the commutator it is best to remove the armature completely and use a scouring pad similar to what you would wash your plates with. You can use wire wool, and if you do (it is quicker and a bit more thorough) make sure you clean between all the comm segments after with a stanley knife or something so there is nothing left to short across them.
The really professional way to sort the comm is to 'skim' it on a lathe, which would mean spinning it up on a lathe and smoothing it out with a hardened cutter. This also leaves the comm nice and flat, ready for new brushes, but should only be done by a competent person as it can go wrong quite easily. Also after skimming you should cut back the insulation slightly so there is a nice step between segments.

I have dewalt 18 v circular saw i cut vinyl lattice once and used it on a 2x4 but it wouldnt cut it, started to cut then just stopped. is blade dull already? new saw.


a couple things to look at. Did the saw stop operating or was the blade not wanting to cut. Remove the battery and CAREFULLY feel the blade for dull or broken segments. If the blalde stopped check to make sure not a loose bolt holding it on. Did you reverse the blade for cutting the vinyl. Let me know more information and I will try and help

I have a circular saw that is locked and the blade won't rotate its brand new how do you free the blade?


Its sounds like the blade lock button is depressed.
looking from the rear of the unit, you should see a button between the left side of the handle and behind the blade shield.
check that. it probably is locked in the depressed position or it may be damaged.

I hope this helps.

How do I change blade


Make sure the saw is unplugged. Raise the arm to the upper postions and raise the blade guard by loosening but not removing the guard screw. Depress the spindle lock button and use the provided wrench to loosen the blade screw.
A full discription, with illustrations can be found on pg 6 of the user manual. In case you have misplaced the manual here is a link to the pdf from Dewalt.

How do I change the blade on a dewalt compound (12 in) miter saw?


With the saw unplugged - The blade needs to be locked in place so it will not turn when you put a wrench on the nut located on the left side of the blade that holds the blade on. This is done with a locking pin on the right side of the blade. Push the pin in and rotate the blade by hand until the pin locks into the blade and prevents it from moving. With the pin pushed in put a wrench on the large nut on the left side of the blade and turn it. This may be reversed threaded, so you may have to turn the nut clockwise in order to loosen it. When tightening the nut after replacing the blade, you will have to once again lock the blade with the same pin.
Perhaps this video will help you locate the locking pin.

This is common IF the blade clamping nut becomes loose... the blade will free wheel on the arbor after the motor stops. It can tear up the arbor so investigate this possibility immediately.

Electric brake does not always stop the blade


check the condition of the brushes for dirt and length. Also if you have compressed air thoroughly blow the motor out. IWhen you look at the brushes UNPLUG the tool and also look at the commutator for unusual discoloration. Sometimes I have to take a commutator stone to clean the contact. Let me know if you need any more help and if I have helped you with would you please rate my response accordingly and Thank you

Either the blade or the guard is out of alignment. You will have to check and find out which one is the culprit.
