SAWDUST BLOWER (FIG. P)
The sawdust blower (4) should be positioned to point to
the blade and workpiece to blow sawdust out of the line-
of-sight when cutting. It is not designed to blow all of the
sawdust off the table.

BLADE SELECTION (FIG. Q)
To avoid injury from accidental starting, always turn
the switch OFF and unplug the scroll saw before
moving, replacing the blade or making adjustments.
This scroll saw accepts 5-in. (127-mm) length blades
with a wide variety of blade thickness and widths. The
type of material and cutting operations (size of radius or
curve) will determine the number of teeth per inch. As
a rule, always select the narrowest blades for intricate
curve cutting and the widest blades for straight and
large curve cutting operations.
The following table represents suggestions for various
materials. When purchasing blades, refer to the back of
the package for the best use of blades and speeds on
various materials.
Use this table as an example, but practice and your own
personal preference will determine the best selection
method.

speeds
NOTE: When using blades, sometimes speeds must
change to compensate for smaller curves, radii or
smaller diameters. Thinner blades will have more
possibilities for blade deflection when cutting angles
which are not perpendicular to the table. Read BASIC
SCROLL SAW OPERATION for more suggestions.
NOTE: The blade must be installed with the teeth
pointing downward, to prevent the workpiece from being
pulled upward by the saw blade action.
