SAWDUST BLOWER (FIG. S) 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, and will operate only when the unit is turned on.

BLADE SELECTION (FIG. T)

! WARNING

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-inch length blades with a wide variety of blade thickness and widths. The type of material and intricacies of cutting operations (size of radius or curve) will determine the number of teeth per inch. As a general 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 be the best selection method.

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, as shown in Fig. T, to prevent the workpiece from being pulled upward by the saw blade action.
