OPERATION

Fig. 12

BLADE INFORMATION

 Scroll saw blades wear out and must be replaced frequently

for best cutting results. Scroll saw blades generally stay

sharp for 1/2 hour to 2 hours of cutting, depending on

type of material and speed of operation.

 In cutting wood, best results are achieved when cutting

wood less than one inch thick.

 When cutting wood thicker than one inch, the user must

guide the workpiece very slowly into the blade and take

extra care not to bend or twist the blade while cutting.

 When choosing a blade, carefully consider the follow-

ing:

• Very fine, narrow blades should be used to scroll cut in

thin material 1/4 in. thick or less.

• Most blade packages state the size or thickness and

type of material which that blade is intended to cut. The

package should also state the radius or size of curve

that can be cut with that blade size.

• Wider blades cannot cut curves as tight or as small as

thinner blades.

 Blades wear faster when:

• Cutting plywood, hardwood, and other laminates.

• Cutting material thicker than 3/4 in.

• Side pressure is applied to the blade.

CHOICE OF BLADE AND SPEED

The scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other fibrous materials. The

saw uses 5 in. long blades of either the pin end or the plain end style. The blade width and thickness and the number of

teeth per inch to use are determined by the type of material and the size of the radius being cut.

NOTE: As a general rule, always select narrow blades for intricate curve cutting and wide blades for straight and large

curve cutting.

USING VARIABLE SPEED

See Figure 12.

 By turning the variable speed knob, the saw’s speed may

be adjusted from a high speed of approximately 1,600

SPM (Strokes Per Minute) to a low speed of approximately

400 SPM.

 To increase the strokes per minute, turn the variable speed

knob clockwise or to the right.

 To decrease the strokes per minute, turn the variable

speed knob counterclockwise or to the left.
