WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle

Additional Safety for Scroll Saws
Serious cuts or amputation can occur from contact with the moving saw blade during operation
or if blade breakage occurs. To reduce this risk, anyone operating this machine MUST completely heed the hazards and warnings below.
HAND PLACEMENT. Never position fingers or
hands in line with the blade. If the workpiece or
your hands slip, serious personal injury could
occur.
INTENDED USE. This machine is intended for
cutting natural and man-made wood products, an d
laminate covered wood products. This machine is
NOT designed to cut metal, glass, stone, tile, etc.
SMALL WORKPIECE HANDLING. If your hands
slip while holding small workpieces with your fingers during a cut, amputation or laceration injuries
could occur. Always support/feed the workpiece
with push sticks, jig, vise, or some type of clamping fixture.
BLADE CONDITION. Do not operate with dull,
cracked, or badly worn blade. Dull blades require
more effort to perform the cut and increase the
risk of kickback. Inspect blades for cracks and
missing teeth before each use.
BLADE TENSION. To avoid mishaps that could
result in operator injury, make sure the blade teeth
face down toward the table and the blade is properly tensioned before operating.
BLADE SPEED. Always allow the blade to come
to full speed before starting the cut. Moving the
workpiece against a blade that is not at full speed
could cause the blade to break or grab the workpiece and draw the operator’s hands into the
blade.
BLADE CONTROL. To avoid serious personal
injury, DO NOT attempt to stop or slow the blade
with your hand or the workpiece. Allow the blade
to stop on its own.
FEED RATE. To avoid the risk of the workpiece
slipping and causing operator injury, always feed
stock evenly and smoothly. DO NOT force or twist
the blade while cutting, especially when sawing
small curves.
CUTTING TECHNIQUES. Plan your operation so
the blade always cuts to the outside of the workpiece. DO NOT back the workpiece away from
the blade while the saw is running, which could
cause kickback and personal injuries. If you need
to back the workpiece out, turn the scroll saw
OFF and wait for the blade to come to a complete
stop. DO NOT twist or put excessive stress on the
blade that could damage it. Instead, use relief cuts
for curve cuts that may twist the blade.
LEAVING WORK AREA. Never leave a machine
running unattended. Allow the scroll saw to come
to a complete stop before you leave it unattended.
CUT-OFF PIECES. Never use your hands to
move cut-offs away from the blade while the saw
is running. If a cut-off becomes trapped between
the blade and table insert, turn the saw OFF and
allow the blade to completely stop before removing it.

SECTION 2: POWER SUPPLY
Before installing the machine, consider the availability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
or equipment damage
may occur if machine is
not properly grounded
and connected to power
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid overloading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:

Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, consult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power supply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:

Troubleshooting
Minimum CFM at Dust Port: 100 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine the
CFM at the dust port, you must consider these
variables: (1) CFM rating of the dust collector,
(2) hose type and length between the dust collector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to calculate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.

Basic Cutting Tips
A properly adjusted scroll saw performs many
types of cuts with ease and accuracy. It is capable
of performing these types of cuts:
Straight Cuts
• Miters, angles and compound angles, ripping, and crosscutting.
Irregular Cuts
• Simple and complex curves, duplicate parts,
circles, and beveled curves.
Basic Cutting Tips
Basic tips to follow when operating a scroll saw:
Workpiece
Inspection
Some workpieces are not safe to cut or may
require modification before they are safe to cut.
Before cutting, inspect all workpieces for the
following:
• Material Type: This machine is intended for
cutting natural and man-made wood products, laminate covered wood products, and
some plastics. Cutting drywall or cementitious backer board creates extremely fine
dust and may reduce life of bearings. This
machine is NOT designed to cut metal, glass,
stone, tile, etc.; cutting these materials with a
table saw may lead to injury.
• Typically, a scroll saw blade stays sharp from
1
⁄2 hour to 2 hours of use, depending on how
blade is used and type of material being cut.
• Best cutting results will be achieved when
cutting workpieces less than 1" thick. When
cutting workpieces thicker than 1", move
workpiece through blade very slowly.
• Blades dull much faster when cutting plywood, hardwoods, and laminates.
• Exerting excessive side pressure on blade
greatly increases chance of blade breakage.
• Plan cut before starting curves. Make relief
cuts in waste areas near tight inside curves,
or leave tight inside curves for a second pass
to minimize backing out. Cut sharp outside
curves by cutting past curve and looping
around to cut from different angle.
When approaching a tight radius, slow down
•
feed rate, but don’t stop. Give teeth time to
make cut. Forcing workpiece through curve
will cause blade to twist or break.
• Foreign Objects: Nails, staples, dirt, rocks
and other foreign objects are often embedded in wood. While cutting, these objects can
become dislodged and hit operator, cause
kickback, or break blade, which might then fly
apart. Always visually inspect your workpiece
for these items. If they can't be removed, DO
NOT cut workpiece.
• Large/Loose Knots: Loose knots can
become dislodged during cutting operation.
Large knots can cause kickback and machine
damage. Choose workpieces that do not
have large/loose knots or plan ahead to avoid
cutting through them.
• Wet or "Green" Stock: Cutting wood with a
moisture content over 20% causes unnecessary wear on blades, increases risk of kickback, and yields poor results.
• Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and
often unpredictable when being cut. DO NOT
use workpieces with these characteristics!
If cut produces waste in interior of curve, turn
•
power OFF and wait until all motion stops
before removing waste.
Scroll saw blades can drift. This is compen-
•
sated for by adjusting feed direction.
-20-
• Minor Warping: Workpieces with slight cupping can be safely supported if cupped
side is facing table or fence. On contrary, a
workpiece supported on bowed side will rock
during a cut and could cause kickback or
severe injury.

If blade tension is too loose, the blade will drift
while cutting, making it difficult to follow your cutting lines. If blade tension is too tight, the blade
can break and damage the saw or the workpiece.
To adjust blade tension:
DISCONNECT MACHINE FROM POWER!
1.
2. Pinch blade and try moving it side to side with
light pressure to check tension. When properly tensioned, blade will deflect only slightly
when moved, and ends will remain firmly in
position.

3.
sary. Perform a test cut on a scrap piece of
wood and repeat this entire procedure if further adjustments are necessary.
IMPORTANT: Blade tension lever must be
in down position to make tension adjustments. Release blade tension lever only
during blade changing operations. If blade
is too tight, lever will be difficult to lower and
could result in damage to blade holder or arm
assembly.

Blade Selection
Scroll saw blades are classified as either "pin-end" (mounting pins in the ends of the blade) or "plain end"
(no pins), as shown in Figure 21. The Model G0938 comes with one pin-end blade and one plain-end blade,
but the scroll saw is designed to accept any 5" (124mm) blade for cutting a wide variety of materials.
The typical format for blade identification is:
Teeth Per InchWidth ThicknessSPMWorkpiece Material
10 TPI0.110 "0.020"1200–1500 General purpose cutting. Hard and soft woods
between

Pin-End Blade
For faster cutting on workpieces more than
(19mm) thick, or when less precision is required
for an operation, pin-end blades are suggested.
This blade type is usually thicker than plain-end
blades and offers greater stability.
When using pin-end blades, the button head cap
screws on the upper and lower blade holders
should not be too tight or too loose. Proper blade
tension will keep the blade securely in place.

from the machine before servicing electrical components!
MODIFICATIONS. Modifying the wiring beyond
what is shown in the diagram may lead to unpredictable results, including serious injury or fire.
This includes the installation of unapproved aftermarket parts.
WIRE CONNECTIONS. All connections must
be tight to prevent wires from loosening during
machine operation. Double-check all wires disconnected or connected during any wiring task to
ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow
the requirements at the beginning of this manual
when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires
or components increase the risk of serious personal injury, fire, or machine damage. If you notice
that any wires or components are damaged while
performing a wiring task, replace those wires or
components.
MOTOR WIRING. The motor wiring shown in
these diagrams is current at the time of printing
but may not match your machine. If you find this
to be the case, use the wiring diagram inside the
motor junction box.
CAPACITORS/INVERTERS. Some capacitors
and power inverters store an electrical charge for
up to 10 minutes after being disconnected from
the power source. To reduce the risk of being
shocked, wait at least this long before working on
capacitors.
EXPERIENCING DIFFICULTIES. If you are experiencing difficulties understanding the information
included in this section, contact our Technical
Support at (570) 546-9663.
