For your own safety, do not use either of the adjustable
dadoes whose model numbers are listed above before
reading and understanding these instructions and
safety rules in their entirety. This will reduce the poten-
tial for accidents which may inflict personal injury
and/or damage the cutting tool. REFER TO THE OWN-

The 720.3263 dado will cut grooves from 3/16" to
13/16" wide. The maximum depth of cut is 1-1/2".
The 720.3267 dado will cut grooves from 1/4" to
13/16" wide. The maximum depth of cut is 2" pro-
viding the saw is capable of producing the I=.pth with
a 7" diameter cutter. To cut grooves wider th: 13/ 16"
make several different cuts. I
READ AND FOLLOW GENERAL AND ADDITIONAL
SAFETY INSTRUCTIONS THAT FOLLOW:

Additional safety instructions for adjustable dadoes.
1_. Do not operate at speed greater than 4500 rpm.
2. Never operate on aradial saw unless the proper
guard is installed and properly adjusted:
—Sawblade guard for top-side operations (dado
vertica|—perpendicu|ar to the table). When
ploughing (rip-type cut: dado stationary and
work slid along the fence), adjust the nose of
the guard and then the spreader and anti-
kickback pawls to just clear the top surface of
the workpiece.
— Molding and Dado Guard #29523 for edge op-
erations (motor arbor vertical).
3. Do not operate on atable saw unless adado insert
is installed and properly adjusted.
4. Replace the sawblade guard on atable saw im-
mediately after completing the dado operation.
5. Never tilt (bevel) the dado on atable saw with
power ‘ON’.
6. Rotate the dado one full turn by hand — before
plugging in electric power and turning saw ‘ON’ —
to be sure it turns freely and does not strike any
part of the table, insert, guard, or motor housing.
7. Never elevate the dado on atable saw so that any
portion of the hub extends into the slot of the
insert.
8. When the workpiece is warped, place the concave
side down against table. DO NOT dado or plough
with concave side up—the work can roll, and
grabbing or akickback could result.
9. Never perform a cut on atable saw that will allow
the dado to cut entirely through the workpiece.
10. Use apushstick for all plough cuts (sliding ma-
terial along fence) that would place your hand or
fingers within six inches of the dado.
11. Do not cut stone, masonry, or metal of any kind.
Use dado for wood, wood products, and plastic
only.
12. BE POSITIVE you provide adequate hold down of
the work to the table when ploughing.
13. Never use both the miter gage and the rip fence
on atable saw for the same operation — use one
or the other.
14. Use awood facing on the fence when rabbeting on
a table saw. Cut into the fence say 1/16", when
rabbeting on aradial saw. For either type saw,
ALWAYS position dado on the fence edge of the
work — to prevent binding of workpiece.
INSTALLATION OF DADO ON SAW.
WITH THE POWER SWITCH “OFF" AND THE POWER
CORD DISCONNECTED, mount the Adjustable Dado on
aradial-arm or table saw the same way as acircular
saw blade. Remove the spreader (splitter) of atable
saw. Abushing is furnished for use on 5/8 in. round
arbors. Place bushing on arbor next to the arbor flange
and position the dado. Check arrows for correct direc-
tion of rotation. Mount the nut, but do not tighten.
If the arbor is not of sufficient length to admit the
flange, place the arbor nut directly next to the dado
head, omitting outer flange. (Do not remove the back
(inside) flange.) Dial the outer hub to the width of cut
desired. Select width to make joint fit either loose or
tight, depending on type of joint required. TIGHTEN
ARBOR NUT after setting desired width of cut.
Install dado insert on table saw, or blade or molding
head guard on radial saw. Elevate dado above table of
table saw to provide depth of cut desired. Rotate the
dado one full turn by hand before plugging in electrical
power and turning saw ‘ON’ to be sure the dado turns
freely and does not strike any part of the saw, including
the table, insert, guard, or motor housing.
To make achange in width of cut, turn switch “OFF”
and disconnect the power cord. Loosen arbor nut, dial
the counter hub to width desired, and re-tighten arbor
nut. Always rotate by hand to check clearance; check
each new setting on scrap wood before cutting your
work piece. For additional information, refer to the
Craftsman Handbook of Circular Saw Blades and Power
Tool Accessories that is enclosed with this accessory.
For best performance and safest operation your dado
should be kept sharp. Adull dado requires excessive
cutting pressure and will break carbide tips. Handle
dado with care—avoid bumping against hard objects
as teeth are easily chipped. Have dado repaired im-
mediately after any tooth damage.
REFER TO THE MODEL NUMBER IN ALL CORRES-
PONDENCE REGARDING THIS DADO.
PACK DADO IN ORIGINAL BOX TO RETURN FOR
SERVICING.
REPAIRED DADOES WILL NOT BE RE-CHROMED.
