OPERATION
MAKING A NON-ThROUGh CUT
See Figure 66.
Non-through cuts (made with a standard 10 in. blade) can
be made with the grain (ripping) or across the grain (cross
cut). The use of a non-through cut is essential to cutting
grooves, rabbets, and dadoes.
This is the only type cut that is made without the blade guard
assembly installed. Make sure the blade guard assembly is
reinstalled upon completion of this type of cut.
Read the appropriate section which describes the type of
cut in addition to this section on non-through or dado cuts.
For example, if your non-through cut is a straight cross
cut, read and understand the section on straight cross cuts
before proceeding.
WARNING:
When making a non-through cut, the cutter is
covered by the workpiece during most of the cut.
Be alert to the exposed cutter at the start and fin-
ish of every cut to avoid the risk of personal injury.
WARNING:
Never feed wood with your hands when making
any non-through cut such as rabbets or dadoes.
To avoid personal injury, always use push blocks,
push sticks, and featherboards.
 Unplug the saw.
 Remove the blade guard and anti-kickback pawls.
 Place spreader / riving knife in "down" position.
 Loosen the height lock knob.
 Adjust the bevel angle to the desired setting.
 Tighten the height lock knob.

 Set the blade to the correct depth for the workpiece.
 Depending on the shape and size of the wood, use either
the rip fence or miter gauge.
 Plug the saw into the power source and turn the saw on.
 Let the blade build up to full speed before moving the
workpiece into the blade.
 Always use push blocks, push sticks, and/or featherboards
when making non-through cuts to avoid the risk of serious
injury.
 When the cut is made, turn the saw off. Wait for the
blade to come to a complete stop before removing the
workpiece.
Once all non-through cuts are completed:
 Unplug your saw.
 Reinstall the spreader/riving knife in the "up" position
then install the blade guard and anti-kickback pawls.
