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

BLADE INFORMATION
• Scroll saw blades wear out and must be re-
placed frequently for best cutting results. Scroll
saw blades generally stay sharp for 1/2 hour to
2 hours of cutting, depending on type of mate-
rial 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. (6 mm) thick
or less.
· Most blade packages state the size or thick-
ness 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 lami-
nates.
· Cutting material thicker than 3/4 in. (19 mm).
· Side pressure is applied to the blade.
USING VARIABLE SPEED
• By turning the variable speed knob, the saw's
speed may be adjusted from a high speed of
approximately 1600 SPM (Strokes Per Minute)
to a low speed of approximately 550 SPM.

Material Cut
soft woods 3/16 in. (4.8 mm) up to
2 in. (51 mm) Plastics, paper, felt,
bone, etc.
Wood, plastics, extremely thin cuts
on materials 3/32 in. (2.4 mm) to 1/2
in. (13 mm) thick.
For tight radius work in thin materi-
als 3/32 in. (2.4 mm) to 1/8 in. (3 mm)
wood, veneer, bone, fiber, ivory,
plastic, etc.
• 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.
WARNING: To avoid possible serious injury
from accidental starting, always turn the saw
off, remove the switch key, and unplug the saw
from power source before removing or replac-
ing the blade.
FLEX SHAFT ASSEMBLY
1. Remove the cap on the right side of the ma-
chine.
2. Insert the in-
ner spindle into the
threaded shaft, then
thread on the flex
shaft.
3. Insert the included drill bit or a tool bit (not
included) into the flex shaft collet.
4. Insert the hex
wrench into the hole
on the collet and
tighten the bit with
the collet wrench.

OPERATION INSTRUCTIONS

BASIC OPERATION OF THE SCROLL SAW
Before starting a cut, watch the saw run. If
you experience excessive vibration or unusual
noise, stop immediately. Turn the saw off, re-
move the switch key, and unplug the saw. Do
not restart until locating and correcting the
problem.
NOTE: After the saw is turned ON, a hesitation
before blade movement is normal.
CUTTING PROCEDURES
• Plan the way you will hold the workpiece
from start to finish.
• Keep your hands away from the blade. Do
not hand hold pieces so small your fingers will
go under the blade guard.
• Hold the workpiece firmly against the saw
table.
• The blade teeth cut material only on the
down stroke.
