tubing because they have a tendency to roll during a cut
causing the blade to "bite." To avoid this, always use a
"V" block or clamp workpiece to a miter gauge
 Before removing loose pieces from the saw table, turn
saw off and wait for all moving parts to stop.
LOCKING THE SWITCH
See Figure 9, page 17.
 Wait until the saw has come to a full and complete stop.
 Place the switch in the OFF position, then remove the
switch key from the switch assembly. Store key in a safe
place.
INSTALLING AND REMOVING BLADES
See Figure 10, page 17.
Scroll saw blades wear out quickly and must be replaced
frequently for best cutting results. Expect to break some
blades while you learn to use and adjust the saw. Blades
generally stay sharp for 1/2 hour to 2 hours of cutting,
depending on the type of material and speed of operation.
REMOVING THE SAW BLADE
 Turn off and unplug the saw from the power source.
 Turn blade tension knob counterclockwise to decrease
(or loosen) blade tension.
 Pushing up from under the saw table, remove the throat
plate.
 Loosen both the upper and lower blade clamp screws.
 Pull up on the blade and push down on the saw arm to
disengage the upper pin in the V-notch of the upper blade
holder. Push the blade downward to disengage the lower
pin in the V-notch of the lower blade holder.
 Remove the blade.
PIN END BLADES
 Turn off and unplug the saw from the power source.
 Remove the blade.
 Place the new blade through the opening in the saw table
with the teeth to the front of the saw and pointing down
toward the saw table. The pins on the blade go under the
blade holder in the V-notch of the lower blade holder.
 Pull up on the blade and press the upper arm down to
position the upper end of the blade in the V-notch in the
upper blade holder.
 Securely tighten the upper and lower blade clamps by
tightening the blade clamp screws.
 Turn the blade tension knob clockwise until the blade has
the desired amount of tension.
 Replace the throat plate.
NOTE: If the blade touches the drop foot on either side then
the drop foot must be adjusted. See section on "Drop Foot."
OPERATION
PLAIN END BLADES
 Turn off and unplug the saw from the power source.
 Remove the blade.
 Place the new blade through the opening in the saw table
with the teeth to the front of the saw and pointing down
toward the saw table.
 Position blade in the lower blade holder and tighten the
blade clamp screw securely.
 Press the upper arm down to position the upper end of
the blade in the upper blade holder.
 Securely tighten the upper blade clamp screw.
 Turn the blade tension knob clockwise until the blade has
the desired amount of tension.
 Replace the throat plate.
NOTE: If the blade touches the drop foot on either
side then the drop foot must be adjusted. See section
Drop Foot.
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 following:
• 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.
