ASSEMBLY
TO CHANGE RIVING KNIFE POSITIONS
See Figure 10.
This saw is shipped with a riving knife that should be placed
in the "down" position for non-through cutting and must be
placed in the "up" position for all other cutting operations.
CAUTION:
Use caution when reaching inside the throat in
the saw table. Blade contact, even when the
blade is still, may result in injury to hands or arms.
 Unplug the saw.
To place in the "up" position for all through cutting:
 Remove the throat plate.
 Raise the saw blade by turning the height/bevel adjusting
handwheel counterclockwise.
 Unlock the release lever by pulling it up.
 Grasp the riving knife and pull it towards the right side of
the saw to release the riving knife from the spring-loaded
riving clamp.
 Pull the riving knife up until the internal pins are engaged
and the riving knife is above the saw blade.
 Lock the release lever by pushing the lever down.
WARNING:
Make sure the release lever is fully seated. If the
release lever is difficult to lock, thoroughly clean
lever components using compressed air or a
clean soft cloth. Failure to completely lock the
release lever can allow the riving knife to change
position during saw use, which could result in
serious personaly injury.
 Reinstall the throat plate.
To place in the "down" position for all non-through cutting:
 Remove the throat plate.
 Raise the saw blade by turning the height/bevel adjusting
handwheel counterclockwise.
 Unlock the release lever by pulling it up.
 Push the riving knife down until it is below the saw blade.
 Lock the release lever by pushing the lever down.
 Reinstall the throat plate.
TO CHECK SAW BLADE INSTALLATION

NOTICE:
To work properly, the saw blade teeth must point
down toward the front of the saw. Failure to do
so could cause damage to the saw blade, the
saw, or the workpiece.
