Unplug the saw. If the blade is moving, wait for it to stop. If the blade arm is locked into its down position, push down slightly on the blade arm to release the tension on the blade arm lock pin. Pull out the lock pin to release the blade arm and allow it to move upward.
Rotate the lower blade guard upward and expose the Phillips-head screw that holds the blade bolt cover in place. Loosen the screw and rotate the blade bolt cover up and out of the way to expose the hex-head blade bolt.
Push the spindle lock button in and rotate the blade bolt until the spindle lock engages fully, stopping the ability of the blade bolt to rotate.
Loosen the blade bolt using a 10-millimeter/12-millimeter combination wrench. The blade bolt is lefthand threaded, which is the reverse of conventional threading. Turn the bolt clockwise to loosen and remove it. Note the placement of the outer washer and remove it as well.
Place a drop of machine oil on the inner blade bolt washer. Do not remove the inner washer. If it is missing, replace it before replacing the blade.
Slide the replacement saw blade up past the lower blade guard and onto the blade spindle. The blade teeth should point downward at the front of the saw. Saw blades often have rotation arrows that can help you double-check that the saw is installed to rotate the correct direction.
Press the spindle lock button in to lock the spindle and reinstall the blade bolt. The blade bolt will tighten in a counterclockwise direction. Replace the blade bolt cover and install the blade bolt cover screw.
Position a combination square to check that the blade is square to the saw fence and saw table. If the blade is not square, refer to the procedures in the manual for squaring the blade to the fence and table.
Things You Will Need
- 10-millimeter/12-millimeter combination wrench
- 5-millimeter hex key
- Combination square
- Phillips screwdriver
- Machine oil
- Overtightening bolts and screws can result in cross-threading. Cross-threading damage compromises the integrity of bolts and screws and can be a difficult error to correct.
- Do not attempt to install a blade that is too thick in the saw. If the blade washer cannot engage the flats on the spindle, the blade is too thick for the saw.
