Question about Dewalt Saws

1 Answer

DW718 miter saw. The blade rotates but does not cut once it makes contact with any resistance. It is as if a cotter pin is broken. How do you repair the problem and what parts would I need. Was working fine and there was nothing to indicate a reason in the cut or the previous as to why it all of sudden occured.

I have 8 differant saws but not a dewalt and have not ever heard of or seen a shear pin on a drive shaft of a motor its a stright shot through the motor to the brushes and there is no gearing or reduction box I would say check the blade connection and washer assembly or the end bearing on the shaft may be worn out and binding under a load. Dose the blade spin true or can you wiggle it from side to side and feel play in the bearing I soppose it could also be some kind of electrical issue where something is shorting under load but that would still bring me back to movement in the shaft that is binding the motor.

My Dewalt miter saw DW718 seems frozen. When I squeeze the handle, the blade doesn't move and the motor makes a sound like it's laboring, but stuck.


There's a little black button to press to lock the blade so you can loosen the screw. Did it get stuck in the in position? Can you turn the blade by hand (unplugged of course)?
I believe the 718 has a belt drive. Could the belt be broken and be buckled or twisted in its case preventing any movement?
Was it left out in the weather and did you get water in the bearings?

My saw makes a loud noice while I'm cutting


I'm wondering what the noise is like. Is the noise only while you are cutting / under load? Is the blade smoking? What type of wood are you cutting?

Blade guard will not retract from full closed position. It must be assisted by hand


either cover is distorted and catches or there is build up of saw cuttings/dust preventing a smooth operation,or the assist spring is broken

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.

When I try to cut a 45 it seems to be cutting a little more than a 45. how do I adjust it?


Make sure the blade is 90 deg vertical to the saw table. Make sure the indicator is set approprately. Raise the blade just enough to clear the table/base. Place a swanson speed square against the fence and blade. Make sure the indicator is at 90 degrees. Here you might want to tilt the square and check that the complete blade is flush against the sqaure as high up as possible. Lay the square back flat on the table and pull the blade toward you as much as possible. The teeth on the blade should ride against the square extented completely out.

Now set the square against the fence with the 45 degree angle coming away from the table and set the blade on the 45 deg mark on the insicator scale.
The blade should touch the square all the way out fully extented.

Or just experiment with some scrap and check

How do i get guard out of way to replace blade..DW718


Make sure the saw is unplugged, manually move the blade guard up to it's fullest extension, push the arbor lock to make sure the arbor and blade do not spin (on front of saw motor housing), then wrench the nut holding the blade to remove. Remove the old blade, install new one and reassemble in reverse order. You can take the guard off completely if you choose, but it is not necessary. I hope this helps and good luck!
