To Check, Replace Or Adjust The Riving Knife And Blade Guard Assembly - Ryobi BT3100K Owner's Operation Manual

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 centre 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.
■ With blade guard up, make sure the riving knife is placed
at least 3mm from the outer points of the blade. See
Figure 29. Then make sure it is centred within the width
of the blade. See Figure 30. If either placement is wrong,
adjust with the following steps.
■ Raise the saw blade by pushing the bevel locking lever to
the left and rotating the blade adjustment handle clockwise.
■ 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 centring.
WARNING:
Properly align riving knife. Improperly aligned riving knife
can cause blade to bind which will increase risk of
kickback.
■ Adjust the bolts front-to-back as needed to place the
riving knife approximately 3mm from the blade's outer
points. Put the nuts back on and tighten.
■ Bring the blade back to the desired angle and height.
Insert the throat plate, lower the blade, and secure the
throat plate with the throat plate screw. Tighten the screw
firmly.
