Well aware that DeWalt is a manufacturer of woodworking power tools, including table saws, miter saws, power drills, routers and much more. No working tool especially a blade is 100% perfect. So, what are the practical steps in changing a Dewalt saw blade?

  1. Unplug the miter saw from the power outlet.
  2. Pull-on the locking pin and raise the miter saw’s blade to a position.
  3. Locate the blade guard bracket screw spotted just to the front of the saw arbor bolt. Loosen this screw two turns anti-clockwise, and lift the upper blade guard up as far as it will move.
  4. Rotate the saw blade slowly by hand and press on the spindle lock key on the right side of the saw blade. When the spindle lock drops as far as it will go, the blade should be locked in place.
  5. Hold the lock with your right hand and lose the arbor bolt in a clockwise motion with your left hand on the wrench that was included with the saw. Remove the arbor bolt and outer washer, next to lift the saw blade off of the arbor.
  6. Insert your new saw blade onto the arbor, with the carbide teeth on the bottom of the blade facing toward the rear of the saw. Tighten the arbor bolt and washer onto the arbor with the wrench to secure the blade. Release the spindle lock with your right hand.
  7. Plugin the saw and make a trial cut.

  • Taking off the Shroud

The first thing that needs to get loosed is a protective shroud. You can do the entire process without doing this particular one, but it is strongly recommended that you do not skip it due to the potential inconveniences later on in the process.

  • Demounting the Blade

Once you have taken the shroud off, it is much easier to get access to all the screws that hold the blade in its place. There is no particular order you should follow when it comes to unscrewing, but we recommend beginning with the supporting screws until the only one left is the one that goes through the blade.

Most modern units feature an index that is parallel to the disc. It’s usually a small button that prevents the axis from rotating and thus unscrewing itself. Before you start unscrewing the blade, find the index and keep it pressed down while you unscrew the main bolt.

Miter Saw Blade Wobble

This topic has raised a lot of argument in some forums globally, as far as Quora. Dewalt is known to sometimes have crappy quality bearing in their saws blades. It is a common problem with the tile saw also. Only a few escape this. Once a blade is noticed, immediately changing is necessary.

The blade on a Skilsaw model 5150 wobbles quite a bit. I can tell the wobble is coming from the shaft itself. (I can grab the shaft and wiggle it around quite a bit — the result of the “looseness” in the shaft is about a 3/16″ wobble on the rim of a 7-1/4″ blade.)

Regardless of which saw you are using to work, you will want to start by unplugging the machine. Even though the machine should be unable to function while powered off, you do not want to take any chances. It can be surprisingly easy to turn the machine on while you are trying to change the parts.

Once the machine is down, you can start the process of changing out the saw blades. You will want to start by putting the blade in the highest position that you can. Once you have done that, raise the blade guard. Find the bracket screw and lose it.

Now that the blade guard is out of the way, you will want to work on the spindle lock. You can get to it by rotating the blade with your hand slowly and looking on the right-hand side of the blade for the spindle lock button. An example is one below:
