Additional Safety Instructions
Specific to this Scroll Saw
Because each shop situation is unique, no list of safety guidelines can ever be complete.
The most important safety feature in any shop is the knowledge and good judgement of the user.
Use common sense and always keep safety considerations, as they apply to your individual shop situation first
and foremost in mind. If you have any doubts about the safety of an operation you are about to
perform: STOP! Do not perform the operation until you have validated from qualified individuals
if the operation is safe to perform and what is the safest method to perform it.
1.
Material hold-down must be properly set and
remain in position during use.
2.
Never reach under the table when operating or
make any adjustments while the scroll saw is running.
3.
Secure the saw to the work bench with clamps or
mounting hardware.
4.
Do not lift or carry the saw by the upper arm.
5.
Make sure blade tension is properly adjusted.
6.
Avoid awkward hand positions where a sudden slip
could cause a hand to move into the saw blade.
Do not place fingers or hands in the path of the saw
blade.
9.
Check for proper blade size and type.
10. Do not attempt to saw stock that does not have a
flat surface unless a suitable support is used.
11. Turn off motor if the material resists being backed
out of an incomplete cut. Use appropriate speed
for applications.
12. CAUTION: Some wood contains preservatives such
as copper chromium arsenate (CCA) which can
be toxic. When cutting these materials, extra care
should be taken to avoid inhalation and to minimize skin contact.
13. Always use a dust mask and safety glasses when
sawing.
14. Keep guards in place and in working order.
7.
8.

When removing short workpieces, or cleaning up
around the table, be sure that the saw is in the OFF
position and that the blade has come to a complete stop.
Never turn the saw ON before making sure that the
table is clear except for the workpiece and related
feed or support devices for the operation planned.
15. Make sure your fingers do not contact the terminals
of the power cord when plugging in or unplugging
the saw.
16. Never overfeed or force work into the blade.
ELECTRICAL REQUIREMENTS
Before connecting the machine to the power source, verify that the voltage of your power supply corresponds with
the voltage specified on the motor I.D. nameplate. A power source with greater voltage than needed can result in
serious injury to the user as well as damage to the machine. If in doubt, contact a qualified electrician before connecting to the power source.
This tool is for indoor use only. Do not expose to rain or use in wet or damp locations.
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit, grounding
reduces the risk of electric shock. The motor of this machine is wired
for 110V single phase operation and is equipped with a 3-conductor cord and a 3-prong grounded plug to fit a grounded type receptacle,
. Do not remove the 3rd prong (grounding pin) to make it
fit into an old 2-hole wall socket. If an adaptor plug is used,
, it
must be attached to the metal screw of the receptacle.
Note: The use of an adaptor plug is illegal in some areas. Check
your local codes.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit your receptacle, have the proper receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand these grounding instructions, or if you are not sure the tool is properly grounded.
EXTENSION CORDS
USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE 3-PRONG GROUNDING PLUGS AND 3-POLE RECEPTACLES THAT ACCEPT
THE TOOLS’ PLUG. REPAIR OR REPLACE A DAMAGED OR WORN POWER CORD OR PLUG IMMEDIATELY.
If you find it necessary to use an extension cord with your machine make sure the cord rating is suitable for the
amperage listed on the motor I.D. plate. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The accompanying chart shows the correct size extension cord to be used based on cord
length and motor I.D. plate amp rating. If in doubt, use the next heavier gauge. The smaller the number the heavier the gauge.

CHOOSING & INSTALLING A SAW BLADE
Blade Selection
Blade selection is dependent on the type and thickness of the material being cut, but is also a matter of experience
and personal preference. There are numerous types of blades available on the market specifically suited for various cutting applications such as metal-cutting and spiral blades which cut in all directions. Try test-cutting with a
sample of each to determine which blade works best for you with different materials. Replacement and specialty
blades can be purchased from a variety of sources. Ask your local tool or scroll saw dealer for suggestions for
unpinned 5” scroll saw blades based on what is available in your area.
Some general guidelines to consider when choosing blades:
•
Wide, thick blades with coarse teeth are suited to cutting straight lines and sweeping curves, but will not turn
tight corners. They will cut aggressively and leave a fairly smooth finish, but may leave burn marks if the work
piece is turned too tightly.
•
Narrower, thinner blades with finer teeth will cut more slowly, but will turn much tighter corners for cutting very
intricate work. They will impart a very smooth, burnished finish that requires no sanding.
•
Consider material thickness when selecting blades. Ensure that a minimum of two or three teeth are in contact with the workpiece at all times. For example, when cutting 1/8” thick material, use a blade with a minimum of of 16 20 teeth per inch.
SKIP TOOTH
Regular evenly spaced tooth pattern. Considered the most common of scroll saw blades, they are available in the
widest range of sizes and provide a good combination of fast cutting action with good chip clearance and a relatively smooth finish.

Installing or changing blades
Fig. 1
Always turn off and unplug the machine before removing, handling or changing blades.
Remove an installed, worn or broken blade by loosening the thumbscrews
and
on the upper and lower blade mounts until the blade
can be removed. (See Fig. 1, 2)
1.
To install a blade, push the blade tension lever
towards the rear of the saw.
(See Fig. 3)
2.
With the blade teeth facing forward, slip one end of the blade
through the hole in the table
. (See Fig. 2)
3.
Fit each end of the blade into the corresponding upper
or lower
blade mounts and tighten the thumbscrews (See Fig. 1, 2) firmly
by hand only – do not use tools.
Fig. 2
Note: Overtightening the blade clamp thumbscrews can cause pre
mature wear to the blades gripping surface and result in blade slippage.
4.
Pull back on the blade tension lever
to increase the tension on the
blade. (See Fig. 3)
Helpful Hints on blade tension: Determining correct blade tension is somewhat subjective. It is learned through experience and is somewhat dependant
on personal preference. A properly tensioned blade will last longer and be
much less likely to break prematurely. If the blade tension is too loose, you will
notice that the blade will have a tendency to drift or slip off-line when cutting
and you may also experience excessive vibration or unusual noise. A blade
that is too tight will break prematurely.

Fig. 3
Assuming the blade has been properly installed in the blade mounts, when the blade tension lever is pulled fully forward
towards the front of the saw, the blade should be properly tensioned. If not, the blade is most likely not properly positioned
in the mounts.
5.
Test the blade tension by lightly plucking on the blade, like you would a guitar string, with your finger. If the blade is
tight and tensioned correctly you will get a clear and even note. If so, you are ready to proceed to operating and
cutting with the saw.
6.
If not tensioned correctly, release the blade tension lever, reset the blade properly in the blade mounts, re-tension
the lever and “pluck-test” again. Proceed to operating and cutting with the saw only when you are satisfied that the
blade is tensioned properly.
Blade storage
There are 6 sockets (mounting holes) on either side of the base of the saw
to hold blade storage “test tubes” (tubes not supplied). Most blade retailers sell blades either already in the tubes or will be able to sell spare tubes
separately. Storing your spare blades in tubes, by size, right on the base of
the machine can be a great way to organize your spare blades so that
they are handy and available when needed. (See Fig. 4)
Fig. 4
OPERATING INSTRUCTIONS
On/Off switch
A simple, dust protected rocker style on/off switch
is located on the top front of the saw. (See Fig. 5)
Adjusting the blade speed
The Ex-21 Scroll Saw is equipped with a variable blade speed control which
allows you to select or fine-tune to the exact blade speed required (from
400-1550 strokes per minute) for best results based on the type and thickness of material and type of blade being used.

Fig. 5
Blade speed selection is subjective and is dependant on a variety of factors: type and thickness of material being
cut, type of blade being used, feed rate, required finish quality as well as experience, personal preference and comfort level of the user. There are no hard and fast rules. Be patient – practice and experience will be your best teacher.
Here are some general guidelines to consider when selecting/adjusting blade speed:
• For best results and smoothest most efficient cutting, always select the highest blade speed that you are comfort
able using based on your experience and skill level.
• Generally speaking, harder or denser workpiece material requires slower blade speeds.
• Slower speeds also work better with very thin blades, or when cutting most metals as well as for brittle or delicate
material such as fine veneers.
• Some wood species will have a tendency to burn quicker at higher blade speeds. To avoid additional sanding
later, reduce blade speed and feed speed at the first signs of burn marks on the workpiece.
Adjusting the Blower
The EX-21 is equipped with a built-in blower to help clear cutting
dust from the workpiece surface in front of the blade and on any
reference lines. Adjust the blower tube
as needed to point the
nozzle at the blade to set it at a comfortable distance so as not to
obstruct your hand movement as you work. (See Fig. 6)
Workpiece Hold-Down
The workpiece hold-down
(See Fig. 6) can be adjusted to assist
in preventing the blade from lifting the workpiece up from the
table during the cut. Loosen the thumbscrew
to set the height
to your convenience based on the thickness of the workpiece.
Before cutting, test to make sure that the hold-down is not adjusted too tightly to the workpiece or that it obstructs the movement
of the workpiece.
Fig. 6
Basic 90° straight or curved cuts
All cuts made with the blade at 90° to the table follow the same basic principals. Start by marking or transferring
your pattern or reference lines onto you workpiece.
Note: The EX-21 has a 21” throat that allow for a workpiece of up to 21” of clearance to swing completely around without
hitting the back of the saw. If necessary, rough-cut the workpiece down to a workable size before starting intricate work on
the scroll saw.

1.
With the saw turned off and unplugged, install the appropriate blade for
the type of material to be cut and the type of cut to be made (Refer to the
section “Choosing and Installing a Saw Blade” on page 9).
2.
Adjust the workpiece hold-down and the blower nozzle to your liking.
3.
Turn on the saw and set the speed controller to the desired blade
speed.
4.
With your fingers holding the piece firm to the table, and using your
thumbs for directional control, (See Fig #7 & 8) feed the workpiece
into the blade using steady, even pressure.
5.
Make sure that the blade is cutting on the waste side of your reference line and adjust feed direction slighty as needed to compensate
for blade drift.
Straight Cuts
Fig. 7
Curved Cuts
Fig. 8
Cutting Tips: To stay in control on tight curve cuts, slow down your
feed rate as needed to allow the blade teeth time to make the cut.
Avoid coming to a complete stop whenever possible as this can
leave burn marks on the workpiece and also makes it more difficult
to get the piece re-started and moving through the cut again. Avoid
forcing through a curve cut as this can cause the blade to twist and
cut off-track or may even cause the blade to break.
Fret Cutting
Fret or inside cutting is an operation that can only be performed on a scroll saw. Fret cutting involves drilling a small
guide or pilot hole through the interior of your pattern on the workpiece, then disconnecting one end of the blade
which is fit through the guide hole and re-connected; essentially using this guide hole as the starting point to cut
out the piece from within. A typical example of fret cutting would be removing the center portion of lettering. (See
Fig. 9)
The EX-21 is a great tool for fret cutting because unlike most scroll saws it
allows you to raise the upper arm with the blade attached, line up the guide
hole in your workpiece with the hole in the table and then lower the arm
while guiding the blade through the hole from above (see step by step
instructions below). This can be a very useful time saving feature, particularly for intricate or complex fret designs that can involve dozens or even hundreds of holes.
1.
2.
With the saw turned off and unplugged, install the appropriate blade
for the type of material to be cut and the type of cut to be made
(Refer to the section “Choosing and Installing a Saw Blade” on page
9 of this manual).
remove portion
Fig. 10
With your pattern or design transferred onto the workpiece, drill a
guide hole in the inside waste portion of the workpiece. (See Fig. 10)
Make sure that the hole is large enough for the blade to fit through.
Helpful hints on drilling guide holes: If multiple fret cuts are required
on the same workpiece, drill all of your required guide holes before
taking the workpiece to the scroll saw. This will keep you from going
back and forth from the saw to the drill press.
To prolong blade life by limiting unnecessary cutting, drill your guide
holes as close as possible to your reference lines. (See Fig. 11)

3.
Release tension on the blade by pushing the blade tension lever towards the rear of the saw.
4.
Loosen the thumbscrew on the lower blade mount, located under the table, to release the blade from the mount.
5.
Raise the upper arm assembly which will lift the blade up through the hole and above the table.
6.
Position the workpiece on the table so that the guide hole lines up with the hole in the table.
7.
Lower the arm assembly with one hand while guiding the blade through the hole in the workpiece and table.
8.
Re-install the bottom end of the blade in the lower blade mount and tighten the thumbscrew to secure the blade
in the lower blade mount.
9.
Pull back on the blade tension lever to re-tension the blade and test the blade tension as described in “Installing
or Changing Blades” section of this manual.
10. To begin cutting follow the same steps as described in “Basic 90° straight or curved cuts” section on page 9 of
this manual.
To reduce the risk of injury, always turn off the saw and wait for the blade to come to a complete stop before
reaching in to remove waste material from a fret cut.
Angle or Bevel Cutting
One of the unique features of the EX-21 Scroll Saw is the ability to tilt the head of the saw in order to make angle or
bevel cuts. The table and the workpiece always stay horizontal (parallel to the floor) while the blade tilts, keeping
your hands in the same comfortable cutting position as they would normally be for regular right angle cuts.
Because you are not fighting gravity or working with your hands or wrists bent in awkward positions, it can be a
huge advantage and makes it easier and safer to make accurate bevel cuts.
The blade tilt controls are located under the table at the front saw. (See
Fig. 12)
To tilt the blade for bevel cutting:
1.
Release the locking lever
by turning counter-clockwise
2.
Pull back and hold the spring loaded indexing pin
from the 90°
stop hole and turn the tilting handle
left or right to set the blade
to the desired angle.
Fig. 12
Note: The spring loaded indexing pin
will allow you to automatically lock in at 90° as well as common angles, 45, 30 & 22.5 both
left and right.
Fig. 13
Fig. 14
When tilting the blade to the left at extreme angles, it may be necessary to remove and reverse the lower blade mount thumbscrew
assembly in order to maximize clearance under the table. (Fig. 13
shows the lower blade mount in default position and Fig. 14 shows it
reversed)
3.
Tighten the locking lever
to secure the blade at the desired angle.
4.
To begin cutting follow the same steps as described in “Basic 90°
straight or curved cuts” section on page 11 of this manual. Fig. 15
shows the scroll saw in position for bevel cutting.
Fig. 15
To reduce the risk of injury, always turn off the saw and wait for the
blade to come to a complete stop before reaching in to remove waste
material.

MAINTENANCE, ADJUSTMENTS AND SERVICING
Handling
Never lift the saw by the upper arm assembly as this
will result in damage to the drivetrain.
Rather lift the saw by the front of the table and by
the motor.
Maintenance
• Always release tension on the blade when the saw is not
in use.
• Clean the saw regularly with a soft bristle brush or by vacuuming to keep cutting dust from accumulating.
• An occasional application of a light dab of grease on
the front and rear trunnions (See Fig. 16) will keep the tilting mechanism working smoothly. If you find the tilting
mechanism becoming more difficult to operate, thoroughly wipe off any built-up cutting dust on the trunnions
and re-apply a little grease.
• The bearings in the drive mechanism are sealed and permanently lubricated and do not need to be oiled or
greased.

Squaring the blade to the table
Fig. 17
Depending on frequency of use and how much the tilting
mechanism is used, normal wear will over time cause the
blade to come slightly out of alignment with the table.
Periodically check the blade for square with the table. When
needed, adjust as described in the following steps to realign the blade square to the table.
1. Turn off and unplug the saw.
2. Using the blade tilt controls at the front of the saw, set the
blade angle to read 0 - which is 90° vertical to the table.
3. Set a machinists square on the table and against the
blade to verify the blade angle. (See Fig. 17)
4. If the blade angle requires adjustment loosen the 4 bolts
in the front trunnion
as well as the 4 bolts on the rear
trunnions
.

5. By hand, move the entire head to bring the blade square
to the table.
6. With the blade square to the table hold the head in position and re-tighten the bolts on the front and rear trunnions.
