Ryobi BT3100-1 Blade Guard Riving Knife, Riving Knife Blade, Inch, Riving Knife Mounting Plate

OPERATION

TO CHECK, REPLACE OR ADJUST THE RIVING KNIFE AND BLADE GUARD ASSEMBLY

The riving knife is mounted between several shims that can be relocated as needed to center the knife behind the blade. It is held in place by two bolts and hex nuts at its base. The bolts are set in slots that permit front-to-back adjustment.

WARNING:

Failure to turn the table saw off, remove the switch key, and unplug the saw before servicing or working on it could result in accidental starting causing possible serious injury.

■Lower the blade.

■Remove the throat plate.

■Raise the saw blade by pushing the bevel locking lever to the left and rotating the blade adjustment handle clockwise.

■With blade guard up, make sure the riving knife is placed at least 1/8 in. from the outer points of the blade. See Figure 29. Then make sure it is centered within the width of the blade. See Figure 30. If either placement is wrong, adjust with the following steps.

■Put the saw in angle mode by moving the bevel locking lever to the right. Slowly turn the blade adjusting handle until the bevel indicator is at a 30˚ angle. Lock the angle by holding the blade adjusting handle with one hand and returning the bevel locking lever to the left with the other.

■With the box end of the small hex key, remove the two nuts at the base of the riving knife. Remove the riving knife/guard assembly.

■Rearrange the riving knife between the shims to achieve the correct centering.

WARNING:

Properly align riving knife. Improperly aligned riving knife can cause blade to bind which will increase risk of kickback.

■Adjust the riving knife on the bolts front-to-back as needed to place the riving knife approximately 1/8 in. from the blade’s outer points. Put the nuts back on and tighten.

■Bring the blade back to the desired angle and height. Lower the blade, insert the throat plate, then securely tighten the throat plate screw.
