Riving Knife

Adjustment

Whenever the blade size is changed (12" or 14" blade), the riving knife must be adjusted to 3mm away from the blade you install.

To adjust the riving knife:

1.Disconnect the saw from the power source!

2.Move the blade tilt to 0˚ (blade 90˚ to table), and raise the main blade as far as it will go.

3.Move the sliding table all the way forward to expose the internal blade guard that covers the blades and riving knife.

4.Pull the blade guard away from the riving knife to expose the mounting assembly. (The internal blade guard is held in place with a magnet.)

5.Loosen the riving knife center bolt, slide the riving knife away from the blade as shown in Figure 57, and slightly tighten.

6.Position the riving knife about 3mm or 18" away from the nearest carbide tooth on the main blade. Note—For a quick gauge, use the 3mm hex wrench to find the correct spac- ing between the blade and the riving knife, as shown in Figure 58.
