OPERATION
 Position the workpiece flat on the table with the edge
flush against the rip fence. Let the blade build up to full
speed before feeding the workpiece into the blade.
 Use a push stick and/or push blocks to move the piece
through the cut and past the blade.
 When the cut is made, turn the saw off. Wait for the
blade to come to a complete stop before removing the
workpiece.
MAKING A NON-THROUGH CUT
See Figure 67.
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 blade is
covered by the workpiece during most of the cut.
Be alert to the exposed blade at the start and
finish of every cut to reduce 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.
