Non-Through Cut; Making A Non-Through Cut - RIDGID R4520 Operator's Manual

OPERATION
 Depending on the shape of the panel, use the rip fence
or miter gauge. If the panel is too large to use either the
rip fence or the miter gauge, it is too large for this saw.
 Make sure the workpiece does not touch the blade before
you turn on the saw.
 Turn the saw on.
 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.
 Using a push stick and/or push blocks, slowly feed the
workpiece toward the blade. Stand slightly to the side of
the wood as it contacts the blade to reduce the chance
of injury should kickback occur.
 Once the blade has made contact with the workpiece, use
the hand closest to the rip fence to guide it. Make sure
the edge of the workpiece remains in solid contact with
both the rip fence and the surface of the table. If ripping a
narrow piece, use a push stick 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 75.
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.
BLADE
GUARD
REMOVED
 Unplug the saw.
 Remove the blade guard and anti-kickback pawls.
 Place riving knife in "down" position.
 Unlock the bevel lock knob.
 Adjust the bevel angle to the desired setting.
 Lock the bevel 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
appropriately when making non-through cuts to reduce
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.
NOTE: A non-through rip cut is shown in the illustration
above. To make a non-through cross cut, remove the blade
guard and anti-kickback pawls. Place the riving knife in the
"down" position and perform the cross cut, see Making a
Cross Cut earlier in this section.
Once all non-through cuts are completed:
 Unplug your saw.
 Place riving knife in "up" position.
 Reinstall blade guard and anti-kickback pawls.
