Making A Dado Cut - RIDGID R4512 Manuel D'utilisation

OPERATION

MAKING A DADO CUT

See Figure 68.
An optional dado throat plate is required for this procedure.
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.
You may purchase an optional dado throat plate (part number
080035003093).
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 in proper location
when reinstalling standard 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.
 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 release lever in unlocked 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.
 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.
Once all dado cuts are completed:
 Unplug your saw.
 Reinstall a standard blade.
 Reinstall the riving knife in the "up" position then install
the blade guard and anti-kickback pawls.
