OPERATING THE TOOL

VARIABLE SPEED CONTROL AND ON/OFF SWITCH
CAUTION
For your own safety, always push
the switch "OFF" when the scroll saw is not in use.
Also, in the case of power failure (all of your lights go out)
push the knob "OFF". Remove the plug from the power
source outlet to avoid accidental starting.
ON/OFF SWITCH (FIG. P)
1. To turn power ON, press on/off switch (1) to "ON"
position.
2. To turn power OFF, press on/off switch (1)
to "OFF" position.
VARIABLE SPEED CONTROL KNOB (FIG. P)
The variable speed control allows greater versatility to cut a
variety of materials such as wood, plastics, non-ferrous
metals, etc. Depending on the hardness and thickness of
material, the speed should be reduced to allow the blade
teeth to remove cut material from the kerf.
1. Your saw is equipped with a variable speed control
knob (2). The blade stroke rate may be adjusted by
simply rotating the variable speed control knob (2).
2. Turn the speed control knob clockwise to increase
up to 1,500 strokes per minute (SPM). Turn the speed
control knob counterclockwise to reduce down to
500 strokes per minute (SPM).
WORK LIGHT (FIG. P)
1. To turn work light on,
press the rocker
switch (3)
to "ON" position.
2. To turn work light
off, press the rocker
switch (3) to "OFF"
position.
RECOMMENDATIONS FOR CUTTING
1. When feeding the workpiece into the blade do not force
the leading edge of the workpiece into the blade because
the it will deflect the blade, reduce the accuracy of
cutting and possibly break the blade. Allow the saw to
cut material by guiding the workpiece into the blade
as it cuts.
2. The blade teeth cut material ONLY on the down stroke.
3. You must guide the wood into the blade slowly because
the teeth of the blade are very small and they can only
remove wood when they are on the down stroke.
4. There is a learning curve for each person who wants to
use this saw. During that period of time it is expected
that some blades will break until you learn how to use
the saw and receive the greatest benefit from the blades.
5. Best results are achieved when cutting wood less than
one inch (25.4 mm) thick.
6. When cutting wood thicker than one inch (25.4 mm),
the user must guide the wood very slowly into the blade
and take extra care not to bend or twist the blade while
cutting in order to maximize blade life.

7. When teeth of scroll saw blade worn out, must replace
the new blade. Check the blade frequently for best
cutting results. Scroll saw blades generally stay sharp
for 1/2 to 2 hours of cutting.
8. To get accurate cuts, be prepared to compensate for
the blade's tendency to follow the wood grain as you
are cutting.
9. This scroll saw is intended to cut wood or wood products.
10. When choosing a blade to use with your scroll saw,
consider very fine, narrow blades to scroll cut in thin
wood in 1/4 in. (6.4 mm) thick or less. Use wider blades
for thicker materials but this will reduce the ability
to cut tight curves.
11. This saw uses 5 in. (127 mm) long pin or plain end
type blades.
12. Blades wear faster when cutting plywood or particle
board which is very abrasive. Angle cutting in hardwoods
reduces blade tooth set faster due to the blade deflection.
FREEHAND CUTTING (FIG. Q)
1. Lay out desired design, or secure design to
the workpiece (1).
2. Raise the blade guard foot (2) by loosening the blade
guard foot lock knob (3).
3. Position the workpiece against the blade and place
the blade guard foot slightly above the top surface
3
of the workpiece.
4. Secure the blade guard foot (2) by tightening the blade
guard foot lock knob (3).
5. Remove the workpiece from the blade before turning
the scroll saw ON. Set the desired speed by turning the
speed control knob (4) clockwise or counterclockwise.
CAUTION
the workpiece and to reduce blade breakage, do not
turn saw ON while the workpiece is against the blade.

6. When turning the scroll saw ON, position the workpiece
against scrap wood prior to touching the leading edge
of the workpiece against the blade.
NOTE: For your own safety, use the scrap wood to
perform the cutting especially for the small workpiece.
7. Slowly feed the workpiece into the blade by guiding and
pressing the workpiece down against the table.
CAUTION
the workpiece into the blade, it may deflect
the blade, reduce accuracy of cutting, and possibly break
the blade.
8. When the cut is
complete, move
the trailing pieces
of the workpiece
beyond the blade
guard foot. Turn
11
the scroll saw OFF.
