Operation (continued)
ON/OFF and speed control switch (Fig. 16)
Always wait for the saw to come to a complete stop before
restarting.
1. To turn the saw on, pull out the control knob (1). When
first starting the saw, it is best to move the control knob
to the middle speed position.
2. Adjust the blade speed to the desired setting between 400
to 1600 strokes per minute (SPM). Turning the control
knob clockwise increases speed; turning it
counterclockwise reduces speed.
3. To turn the saw off, push the control knob (1) in.
Note: A small lock may be placed between the power knob and the metal switch guard (2) to
prevent accidental operation. It is recommended to lock the saw when not in use.
WARNING: To avoid injury from accidental start-ups, always turn the switch OFF and
unplug the scroll saw before moving the tool, replacing the blade, or making adjustments.
Freehand cutting (Fig. 17)
1. Lay out desired design, or secure design to the work
piece.
2. Raise the blade guard foot (1) by loosening the height
adjustment knob (2).
3. Position the work piece against the blade and place the
blade guard foot against the top surface of the work
piece.
4. Secure the blade guard foot (1) by tightening the height
adjustment knob (2).
5. Remove the work piece from the blade prior to turning
the scroll saw ON.
CAUTION: In order to avoid uncontrollable lifting of the
work piece and to reduce blade breakage, do not turn the switch on while the work piece is against
the blade.
6. Slowly feed the work piece into the blade by guiding and pressing the work piece down against
the table.
CAUTION: Do not force the leading edge of the work piece into the blade. The blade will deflect,
reducing accuracy of cut, and may break.
7. When the cut is complete, move the trailing edge of the work piece beyond the blade guard foot.
Turn the switch OFF.
