How to Adjust the Laser on a Craftsman Miter Saw

The Craftsman miter saw uses a laser light beam on the handle to assist in lining up your workpiece when making cuts. The most common adjustment necessary on the laser is to zero the beam over the cut line to get perfect cuts each time you use the saw. The laser beam also has an angle adjustment that requires adjustment from time to time as well. The Craftsman miter saw should not be plugged in when performing adjustments on the battery-operated laser.

Things You'll Need

  • Scrap piece of wood
  • Phillips screwdriver

Mark a straight line across a piece of scrap wood with a pencil. Place the wood on the miter saw table beneath the saw blade.

Lower the handle of the miter saw until the blade is to the left side of the line. Move the piece of wood side to side as necessary to align the blade with the line.

Turn on the laser on the saw handle. Notice where the laser light beam hits the wood. The beam should be on the line. Locate the adjustment screw on top of the laser box near the thumbscrew.

Loosen the screw 1/8 turn with a Phillips screwdriver. Turn the thumbscrew in either direction with your fingers to line up the laser beam with the line on the wood. Tighten the adjustment screw when the beam lines up with the line on the wood.

Locate the adjustment screw in the front of the laser, if the beam is at an angle to the straight line. Turn the screw 1/8 turn left or right with a Phillips screwdriver until the beam is parallel with the line on the wood.
