SETUP
Preparing Table Saw
The Model D4902 Tenoning Jig is designed to work with a
table saw that has a
3
⁄8" x
3
⁄4" miter T-slot on the left side
of the blade. To help ensure safe and accurate tenons,
follow these rules to properly prepare your table saw
before using it with the jig.
• Table Saw Operation: Make sure that you read and
understand your table saw owner's manual, and take
all instructed safety precautions.
• Riving Knife: You must use a riving knife that is
properly installed behind the blade to ensure the
kerf does not close on the blade and cause kickback.
• Saw Blades: Make sure that your saw blades are not
damaged and that the teeth are sharp.
• Saw Adjustments: When using the tenoning jig,
the accuracy of the cuts depend upon the accuracy
of the saw blade. Make sure that your saw blade
is perpendicular to the table and parallel with the
miter slots.
• Miter Slot and Table: Make sure the miter slots
and table are free from burrs or debris that may
interfere with the smooth operation of the jig.
• Lighting: Make sure the top of your table has
adequate lighting so that the tenoning jig and
workpiece are properly illuminated without shadows.
Always disconnect power to the table
saw before performing adjustments,
maintenance, or service to the saw
or tenoning jig. Failure to do this may
result in serious personal injury.
