MAKING A DADO CUT

See Figure 68.
An optional dado throat plate is required for this procedure
(see the Accessories section of this manual and check with
the retailer where the table saw was purchased). All blades
and dado sets must not be rated less than the speed of this
tool. This saw is designed for use with an up to 8 in. stack
dado (up to width of 13/16 in., with a maximum depth of
cut of 1-1/2 in.). Do not use an adjustable dado on this saw.
NOTE: Do not set beyond 1-1/2 in. Ensure that the release
lever is not raising the throat plate.
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:
Always put all blade washers, spacers, and nuts
in proper location when changing back to saw
blade. Failure to do so can result in possible injury
and damage to the tool.
WARNING:
Always use push blocks, push sticks, and/or
featherboards when making dado cuts to avoid
the risk of serious injury.
 Unplug your saw.
 Remove the blade guard, anti-kickback pawls, throat
plate, and riving knife.
 Remove the blade nut, outer blade washer, saw blade,
inner blade washer, and spacer.
NOTE: Always store the blade washer and throat plate
in a secure location.
 Reinstall the inner blade washer.
 Mount the dado blade, according to manufacturer
instructions, using the blade and chippers appropriate
for the desired width of cut.
BLADE
GUARD
REMOVED
 Reinstall the blade nut.
NOTE: The blade washer may be used provided the arbor
shaft extends slightly beyond the arbor nut.
 Make sure the blade nut is fully engaged and the arbor
extends past a securely tightened blade nut.
 Place riving knife release lever in locked position.
 Install the dado throat plate and rotate the blade by hand
to make sure it turns freely then lower the blade.
 Set the blade height.
 Depending on the shape and size of the wood, use either
the rip fence or miter gauge.
NOTE: If you cannot use either the rip fence or miter
gauge, you cannot make a dado cut with this saw.
 If making a rip cut, install feather board in the appropriate
position for the cut being made.
 Turn the saw on.
NOTE: Make sure the wood does not touch the blade
before you turn on the saw. Let the blade build up to full
speed before feeding the workpiece into the blade.
 Position the workpiece flat on the table with the edge
flush against the rip fence or miter gauge.
 Use a push block or push stick to move the wood through
the cut past the blade. Never push a small piece of wood
into the blade with your hand, always use a push stick.
The use of push blocks, push sticks, and featherboards
are necessary when making non-through cuts.
 When the cut is made, turn the saw off. Wait for the
blade to come to a complete stop before removing the
workpiece.
