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 blade will deﬂect, reducing the accuracy
of cut and possibly breaking 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. Teeth on scroll saw blades wear out and must be

replaced 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 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. U)
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 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 prior to turning

the scroll saw ON. Pull the variable speed control
knob (4) out and set the desired speed by turning the
control knob clockwise or counterclockwise.

CAUTION

In order to avoid uncontrollable lifting of 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

Do not force the leading edge of the workpiece into
the blade. The blade will deﬂect, reducing accuracy
of cut, and may break.

8. When the cut is complete, move the trailing edge of
the workpiece beyond the blade guard foot. Turn the
scroll saw OFF.
