How to Unlock a Miter Saw

A high-quality miter saw enables an average handy-man to consistently produce picture-perfect accurate angle cuts with ease. The tool is easy to set-up, quick to use and often designed for portable storage. To use it correctly, as well as to store the power tool safely, you must first secure all the moving parts and lock them in place. There’s a lock for safe and convenient storage, one for adjusting the cut angle, plus another one to control the speed of the blade’s movement. If you want to stay safe and have full control of your miter saw, learn to use these locks.

Rail Lock
The rail lock, which is usually a knob located on the base of the saw’s blade arm, is used to lock the arm in place. There are certain cuts that require partial use of the rail lock. For the most part, however, it is used to make sure the head is locked-in when transporting the miter saw.

As a safety precaution, use this lock whenever you aren’t using your power saw. Once the arm is in a folded position, the blade shouldn’t be accessible. Make sure the ‘naked’ teeth of the blade are completely submerged under the table, and that the guard is covering the rest of them.

Blade Lock
The blade lock is a pin, which is usually located on the rear side of a miter saw. To unlock the blade, press the head down and pull on the pin until it’s released. At this point, there will be a click and the blade will life up automatically. Make sure the blade guard gradually covers its exposed ‘teeth’ as the arm moves into position. If the guard is stationary, you’ll need to clean it before using the miter saw. To lock the blade, bring the head down and push the pin inward.

Angle Control Lock
There should be a large knob in the front of your miter saw, as well as a lever right underneath (or on top of) the knob. Many modern models utilize different placement of the angle controls, in which case you should look for a knob adjacent to a lever.

The lever is used to lock in common angles. To use it, pull the lever and move the handle to a desired angle. If you pass any common angle stops, you will hear a clicking sound. Release the lever when you reach the desired angle setting. Twist the knob clockwise to lock the angle.
