1.
With the saw turned off and unplugged, install the
appropriate blade for the type of material to be
cut and the type of cut to be made (Refer to the
section "Choosing and Installing a Saw Blade" on
page 10).
2.
Adjust the workpiece hold-down and the blower
nozzle to your liking.
3.
Turn on the saw and set the speed controller to
the desired blade speed.
4.
With your fingers holding the piece firm to the ta-
ble, and using your thumbs for directional control,
feed the workpiece into the blade using steady,
even pressure.
5.
Make sure that the blade is cutting on the waste
side of your reference line and adjust feed direc
tion slighty as needed to compensate for blade
drift.
Cutting Tips: To stay in control on tight curve cuts, slow down your feed rate as needed to allow the blade teeth time to
make the cut. Avoid coming to a complete stop whenever possible as this can leave burn marks on the workpiece and
also makes it more difficult to get the piece re-started and moving through the cut again. Avoid forcing through a curve
cut as this can cause the blade to twist and cut off-track or may even cause the blade to break.

FRET CUTTING

Fret or inside cutting is an operation that can only be performed
on a scroll saw. Fret cutting involves drilling a small guide or pilot
hole through the interior of your pattern on the workpiece, then
disconnecting one end of the blade which is fit through the
guide hole and re-connected; essentially using this guide hole
as the starting point to cut out the piece from within. A typical
example of fret cutting would be removing the center portion of
lettering A.
The EX-16 is a great tool for fret cutting because unlike most
scroll saws it allows you to raise the upper arm with the blade
attached, line up the guide hole in your workpiece with the
hole in the table and then lower the arm while guiding the
blade through the hole from above (see step by step instruc-
tions below). This can be a very useful time saving feature, par-
ticularly for intricate or complex fret designs that can involve
dozens or even hundreds of holes.
Note: The upper arm locks in place in the raised position for easi-
er insertion of the blade through the hole in the workpiece and for
easier blade changes.

With the saw turned off and unplugged, install the
appropriate blade for the type of material to be cut and the
type of cut to be made (Refer to the section "Choosing and
Installing a Saw Blade" on page 10 of this manual).
2.
With your pattern or design transferred onto the workpiece,
drill a guide hole in the inside waste portion of the work-
piece B. Make sure that the hole is large enough for the
blade to fit through.
Helpful hints on drilling guide holes: If multiple fret cuts are
requi-red on the same workpiece, drill all of your required
guide holes before taking the workpiece to the scroll saw.
This will keep you from going back and forth from the saw
to the drill press.
To prolong blade life by limiting unnecessary cutting, drill
your guide holes as close as possible to your reference
lines C .
