In order to do this, you must first unplug your saw and let the motor get cooled down. If needed, take out the brush from beneath the cap and substitute it with a new one if the carbon on it is of less than ¼ inch thickness.

Adjusting the Blade’s Depth:

If you find the blades striking the work table, you must first adjust the depth stop. For this again, you must first shut down the running compound miter saw and take off the work piece from it. Now, drop down the cutting head such that the teeth of the saw blade are stretched by around ¼ inches beneath the throat plate. Then, unwind the wing nuts and recalibrate the blade’s depth to the required measurement. When this has been done, try running the blade again with the saw still switched off, and ensure that the blades don’t hit anything.

If the cutting head of your compound miter saw doesn’t rise after you made a cut, then, you must alter the cutting head assembly axis. For this, you must first unwind the lock nut that is given on the head and then, tighten the hex bolt for putting more thrust over the spring.

If this is the case, then you must remove the blades and mount them correctly. If the blades are not cutting properly, there are chances that there is gum or pitch on the blades. For solving this issue, you must remove the blade from the saw and clean it using turpentine soaked in coarse steel wool.

Another reason for getting unsatisfactory cuts from your compound miter saw might be the use the incorrect blade for the work being done by you. For sorting this out, check and change the blade type.
