RULES FOR SAFE OPERATION
Safe operation of this power tool requires that you read and
understand this operator's manual and all labels affixed to
the tool. Safety is a combination of common sense, staying
alert, and knowing how your scroll saw works.
READ ALL INSTRUCTIONS
■ KNOW YOUR POWER TOOL. Read the operator's
manual carefully. Learn the applications and limitations
as well as specific potential hazards related to this tool.
■ GUARD AGAINST ELECTRICAL SHOCK by preventing
body contact with grounded surfaces. For example:
pipes, radiators, ranges, refrigerator enclosures.
■ KEEP GUARDS IN PLACE and in working order. Never
operate the tool with any guard or cover removed. Make
sure all guards are operating properly before each use.
■ REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see keys and adjusting wrenches are
removed from tool before turning it on.
■ KEEP THE WORK AREA CLEAN. Cluttered work areas
and work benches invite accidents.
■ DON’T USE IN DANGEROUS ENVIRONMENTS. Do not
use power tools near gasoline or other flammable liquids,
in damp or wet locations or expose them to rain. Keep
work area well lighted.
■ KEEP CHILDREN AND VISITORS AWAY. All visitors
should wear safety glasses and be kept a safe distance
from work area.
■ MAKE WORKSHOP CHILDPROOF with padlocks,
master switches, or by removing starter keys.
■ DON’T FORCE THE TOOL. It will do the job better and
safer at the rate for which it was designed.
■ USE THE RIGHT TOOL. Do not force the tool or
attachment to do a job for which it was not designed.
■ USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to carry
the current your product will draw. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension cord 25 feet or less in
length. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
■ WEAR PROPER APPAREL. Do not wear loose clothing,
neckties, or jewelry that can get caught in the tool’s
moving parts and cause personal injury. Nonslip footwear
is recommended when working outdoors. Wear protective
hair covering to contain long hair.
■ ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-
resistant lenses; they are NOT safety glasses.
■ SECURE WORK. Use clamps or a vise to hold work when
practical. It’s safer than using your hand and it frees both
hands to operate the tool.
■ DO NOT OVERREACH. Keep proper footing and balance
at all times.
■ MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for best and safest performance. Follow instructions
for lubricating and changing accessories.
■ DISCONNECT ALL TOOLS. When not in use, before
servicing, or when changing attachments, blades, bits,
cutters, etc., all tools should be disconnected from power
source.
■ REDUCE THE RISK OF UNINTENTIONAL STARTING.
Be sure switch is off when plugging in.
■ USE RECOMMENDED ACCESSORIES. Consult the
operator’s manual for recommended accessories. The
use of improper accessories may cause risk of injury.
■ NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the blade is unintentionally contacted.
■ CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts,
mounting and any other conditions that may affect its
operation. A guard or other part that is damaged must be
properly repaired or replaced by an authorized service
center to avoid risk of personal injury.
■ DIRECTION OF FEED. Feed work into a blade or cutter
against the direction or rotation of the blade or cutter only.
■ NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool until it comes to a
complete stop.
■ DON’T ABUSE CORD. Never carry tool by the cord or
yank it to disconnect from receptacle. Keep cord from
heat, oil, and sharp edges.
■ PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
■ PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
■ BLADE COASTS AFTER TURN OFF.
■ KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND
GREASE. Always use a clean cloth when cleaning.
Never use brake fluids, gasoline, petroleum-based
products, or any solvents to clean tool.
■ INSPECT TOOL CORDS AND EXTENSION CORDS
PERIODICALLY and, if damaged, have repaired by a
qualified service technician. Stay constantly aware of cord
location and keep it well away from the rotating wheel.
■ NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal
sparking of the motor could ignite fumes.
■ USE ONLY OUTDOOR EXTENSION CORDS with
approved ground connection that are intended for use
outdoors and so marked.
■ BE SURE THE BLADE PATH IS FREE OF NAILS.
Inspect for and remove nails from lumber before cutting.

RULES FOR SAFE OPERATION
■ AVOID AWKWARD OPERATIONS AND HAND POSI-
TIONS where a sudden slip could cause your hand to
move into the blade. ALWAYS make sure you have good
balance.
■ ALLOW THE MOTOR TO COME UP TO FULL SPEED
before starting a cut to avoid binding or stalling.
■ DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
■ REPLACEMENT PARTS. All repairs, whether electrical
or mechanical, should be made by qualified service
technician at an authorized service center.
■ WHEN SERVICING use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or cause
product damage.
■ KEEP HANDS AWAY FROM CUTTING AREA. Do not
hand hold pieces so small that your fingers go under the
blade guard. Do not reach underneath work or in blade
cutting path with your hands and fingers for any reason.
■ FIRMLY CLAMP OR BOLT your saw to a stable, level
workbench or table. The most comfortable table height is
approximately waist height.
■ DO NOT FEED THE MATERIAL TOO QUICKLY. Do not
force the workpiece against the blade.
■ USE ONLY CORRECT BLADES. Use the right blade
size, style and cutting speed for the material and the type
of cut. Blade teeth should point down toward the table.
■ BEFORE MAKING A CUT, BE SURE ALL ADJUST-
MENTS ARE SECURE.
■ ALWAYS SUPPORT LARGE WORKPIECES while cut-
ting to minimize risk of blade pinching and kickback. Saw
may slip, walk or slide while cutting large or heavy boards.
■ DO NOT REMOVE JAMMED CUTOFF PIECES until
blade has stopped.
■ NEVER START THE TOOL when the blade is in contact
with the workpiece.
■ NEVER TOUCH BLADE or other moving parts during
use.
■ BEFORE CHANGING THE SETUP, REMOVING COVERS, GUARDS, OR BLADES, unplug the saw and
remove the switch key.
■ KEEP BLADES CLEAN, SHARP, AND WITH SUFFI-
CIENT SET. Sharp blades minimize stalling and kick-
backs.
■ ALWAYS TURN OFF SAW before disconnecting it to
avoid accidental starting when reconnecting to a power
source.
■ DO NOT OPERATE THIS TOOL WHILE UNDER THE
INFLUENCE OF DRUGS, ALCOHOL, OR ANY
MEDICATION.
■ STAY ALERT AND EXERCISE CONTROL. Watch what
you are doing and use common sense. Do not operate
tool when you are tired. Do not rush.
■ MAKE SURE WORK AREA HAS AMPLE LIGHTING to
see the work and that no obstructions will interfere with
safe operation BEFORE performing any work using your
saw.
■ SAVE THESE INSTRUCTIONS. Refer to them frequently
and use them to instruct other users. If you loan someone
this tool, loan them these instructions also.
WARNING:
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals, work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter
out microscopic particles.

ELECTRICAL
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.
Length of Extension Cord Wire Size (A.W.G.)
Up to 25 feet 16
26-100 feet 16
When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters WA on the cord's jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation. Repair or replace
a damaged or worn cord immediately.
CAUTION:
Keep the cord away from the cutting area and position the
cord so that it will not be caught on lumber, tools, or other
objects during cutting.
ELECTRICAL CONNECTION
Your Ryobi Scroll Saw is powered by a precision built electric
motor. It should be connected to a power supply that is 120
volts, 60Hz, AC only (normal household current). Do not
operate this tool on direct current (DC). A substantial voltage
drop will cause a loss of power and the motor will overheat.
If the saw does not operate when plugged into an outlet,
double check the power supply.
GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an
electric cord having an equipment-grounding conductor and
a grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have
the proper outlet installed by a qualified electrician. Improper
connection of the equipment-grounding conductor can result
in a risk of electric shock. The conductor with insulation
having an outer surface that is green with or without yellow
stripes is the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet like
the one shown in
one shown.

ASSEMBLY
Attach the plastic tubing to the sawdust blower and bellows
tube on the top of the saw housing.
Apply a coat of paste wax to the saw table surface to allow
the workpiece to slide easily across the surface. Wipe the
saw table thoroughly with a dry cloth to remove excess wax.
MOUNTING SCROLL SAW TO WORKBENCH
WARNING:
To avoid serious personal injury from unexpected tool
movement, always securely mount scroll saw to a
workbench.
If the scroll saw is to be used in a permanent application, we
recommend that you secure it in a permanent location such
as a workbench. When mounting the saw to a workbench,
holes should be drilled through the supporting surface of the
workbench.
■ Each hole in the base of the saw should be bolted
securely using machine bolts, washers, and nuts (not
included). Bolts should be of sufficient length to accommodate the saw base, washers, nuts, and the thickness
of the workbench.
■ Place scroll saw on workbench. Using the saw base as a
pattern, locate and mark the holes where the scroll saw is
to be mounted.
■ Drill four holes through the workbench.
■ Place scroll saw on workbench aligning holes in the saw
base with the holes drilled in the workbench.
■ Insert all four bolts (not included) and tighten securely
with washers and nuts (not included).
Note: All bolts should be inserted from the top. Install the
washers and nuts from the underside of the bench.
Supporting surface where scroll saw is mounted should be
examined carefully after mounting to insure that no movement during use can result. If any tipping or walking is noted,
secure workbench or supporting surface before beginning
cutting operations.
Reducing Noise and Vibration:
You may wish to place a foam pad or piece of carpet between
the saw base and the workbench to help reduce noise and
vibration.
If a foam pad or piece of carpet is used, do not overtighten
the mounting bolts. Leave some cushion between the padding and the saw base to help absorb the noise and vibration.
The size of the padding material should be approximately
24 in. x 12 in. x 1/2 in. (610 mm x 305 mm x 13 mm).
CLAMPING SCROLL SAW TO WORKBENCH
See Figure 5.
If the scroll saw is to be used in a portable application, it is
recommended that you fasten it permanently to a mounting
board that can easily be clamped to a workbench or other
supporting surface. The mounting board should be of
sufficient size to avoid tipping of saw while in use. Any good
grade plywood or chipboard with a 3/4 in. (19 mm) thickness
is recommended.
■ Mount saw to board using holes in saw base as a template
for hole pattern. Locate and mark the holes where scroll
saw is to be mounted.
■ Follow last three steps in previous section called
Mounting Scroll Saw to Workbench.
If lag bolts are being used, make sure they are long enough
to go through holes in the saw base and the material the saw
is being mounted to.
If machine bolts are being used, make sure they are long
enough to go through holes in the saw base, the material the
saw is being mounted to, and the washers and nuts.
Note: It may be necessary to countersink washers and nuts
on the bottom side of mounting board.

OPERATION
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, remove 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
■ 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 and
adjust the saw.
■ 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.
■ Use gentle pressure and both hands when feeding the
work into the blade. Do not force the work.
■ Guide the workpiece into the blade slowly because the
teeth of the blade are very small and can only remove
material on the down stroke.
■ Avoid awkward operations and hand positions where a
sudden slip could cause serious injury from contact with
the blade. Never place hands in blade path.
■ To get accurate cuts, compensate for the blade's
tendency to follow the wood grain as you are cutting
wood.
■ Use extra supports (tables, saw horses, blocks, etc.)
when cutting large, small or awkward workpieces.
■ Never use another person as a substitute for a table
extension or as additional support for a workpiece that is
longer or wider than the basic saw table.
■ When cutting irregularly shaped workpieces, plan your
work so it will not pinch the blade. Workpieces must not
twist, rock or slip while being cut.
WARNING:
Before removing loose pieces from the table, turn saw off
and wait for all moving parts to stop to avoid serious
personal injury.
AVOIDING INJURY
■ Make sure saw is level and does not rock. Saw should
always be on a firm, level surface with plenty of room for
handling and properly supporting the workpiece.
■ Bolt saw to the support surface to prevent slipping,
walking or sliding during operations like cutting long,
heavy boards.
■ Turn saw off, remove switch key, and unplug cord from
the power source before moving the saw.
■ Do not remove jammed cutoff pieces until blade has come
to a full and complete stop.
■ Choose the right size and style blade for the material
and type of cut you plan to do.
■ Use only recommended accessories.
■ With the exception of the workpiece and related support
devises, clear everything off the saw table before turning
the saw on.
■ Properly support round materials such as dowel rods or
tubing because they have a tendency to roll during a cut
causing the blade to “bite”. To avoid this, always use a
“V” block or clamp workpiece to a miter gauge
■ Before removing loose pieces from the saw table, turn
saw off and wait for all moving parts to stop.
LOCKING THE SWITCH
See Figure 11.
■ Wait until the saw has come to a full and complete stop.
■ Place the switch in the OFF position, remove the switch
key from the switch assembly. Store key in a safe place.
REMOVING JAMMED MATERIAL
When backing out the workpiece, the blade may bind in the
kerf (cut). This is usually caused by sawdust clogging the
kerf or when the blade comes out of the blade holders. If this
happens:
■ Wait until the saw has come to a full and complete stop.
■ Place the switch in the OFF position, remove the switch
key from the switch assembly. Store key in a safe place.
■ Unplug the saw from the power source.
■ Remove the saw's blade and the workpiece, see section on
Removing the Saw Blade, page 13.
■ Wedge the kerf open with a flat screwdriver or wooden
wedge then remove the blade from the workpiece.

OPERATION
CHOICE OF BLADE AND SPEED
The scroll saw accepts a wide variety of blade widths and thicknesses for cutting wood and other fibrous materials. Your saw
uses 5 in. long blades of either the pin end or the plain end style. The blade width and thickness and the number of teeth per
inch to use are determined by the type of material and the size of the radius being cut.
Note: As a general rule, always select narrow blades for intricate curve cutting and wide blades for straight and large curve
cutting.
Speed or
Teeth/Inch Width Thickness Strokes Per Material Cut
Minute
10 .110 in. .020 in. 1200-1600 Popular size for cutting hard and soft
(2.8 mm) (0.5 mm) woods 3/16 in. (4.8 mm) up to 2 in. (51 mm)
Plastics, paper, felt, bone, etc.
15 .110 in. .020 in. 600-1200 Wood, plastics, extremely thin cuts on
(2.8 mm) (0.5 mm) materials 3/32 in. (2.4 mm) to 1/2 in.
(13 mm) thick.
18 .095 in. .010 in. 400-600 For tight radius work in thin materials
(2.4 mm) (0.3 mm) 3/32 in. (2.4 mm) to 1/8 in. (3 mm) wood,
veneer, bone, fiber, ivory, plastic, etc.
BLADE INFORMATION
■ Scroll saw blades wear out and must be replaced frequently for best cutting results. Scroll saw blades generally stay sharp for 1/2 hour to 2 hours of cutting, depending on type of material 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 thickness 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 laminates.
• Cutting material thicker than 3/4 in. (19 mm).
• Side pressure is applied to the blade.
USING VARIABLE SPEED
See Figure 12.
■ 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 400 SPM.
■ 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
replacing the blade.
DRILL HOLE
SCROLL CUTTING
For general type scroll cutting, follow the pattern lines by
pushing and turning the workpiece at the same time. Do
not try to turn the workpiece while engaged in the blade
without pushing it – the workpiece could bind or twist the
blade.
WARNING:
To prevent serious personal injury, never leave the saw
unattended until the blade has come to a complete stop.
INTERIOR SCROLL CUTTING
See Figure 13.
■ One feature of a scroll saw is that it can be used to make
scroll cuts on the interior of a workpiece without breaking
or cutting through the edge or perimeter of the board.
■ To make interior cuts in the workpiece, remove the scroll
saw blade as explained in the section on Installing
Blades on page 13.
■ Drill a 1/4 in. (6 mm) hole in the workpiece.
■ Place the workpiece on the saw table with the drilled hole
over the access hole in the table.
■ Install blade through the hole in the workpiece; adjust the
drop foot and blade tension.
■ When finished making the interior scroll cuts, simply
remove the blade from the blade holders as described in
the section on Installing Blades, page 13, and remove
the workpiece from the saw table.

WARNING:
To avoid possible, serious personal injury, do not cut
more than one loose piece of material at a time.
WARNING:
Do not allow familiarity with your saw to make you
careless. Remember that a careless fraction of a second
is sufficient to inflict severe injury.
STACK CUTTING
See Figure 14.
After becoming well acquainted with your saw through
practice and experience, you may wish to try stack cutting.
Stack cutting may be used when several identical shapes
need to be cut. Several pieces of wood may be stacked on
top and secured to each other before cutting. The wood
pieces may be joined together by placing double sided tape
between each piece or by wrapping masking tape around the
corners or ends of the stacked wood. You must attach the
stacked pieces of wood to each other so they will move on
the table as a single piece of material.

MAINTENANCE
WARNING:
When servicing, use only identical Ryobi replacement
parts. Use of any other part may create a hazard or cause
product damage.
GENERAL MAINTENANCE
■ Keep your scroll saw clean.
■ After cleaning the table top initially, apply a thin coat of
automobile type (paste) wax to the table top so the wood
slides easily while cutting.
■ Do not allow pitch to accumulate on the saw table. Clean
with gum and pitch remover.
ARM BEARINGS
See Figure 15.
Lubricate the arm bearings after the first 10 hours of use. Oil
after every 50 hours of use or whenever there is a squeak
coming from the bearings.
■ Carefully place the saw on its side as shown in
Remove the rubber cap from the upper and the lower arm
of the saw.
■ Squirt a few drops of SAE20 oil around the shaft end and
arm bearings. Let oil soak in overnight, remaining in this
position.
Note: Lubricate the bearings on the other side of the saw in
this same manner.
Figure 15.
MOTOR BRUSHES
See Figure 16.
Your saw has externally accessible motor brush assemblies
that should be checked periodically for wear. When one of
the two brushes becomes worn, replace both brushes.
■ Unplug the saw from the power source.
■ Carefully place the saw on its side exposing the under-
side of the saw housing.
■ Using a flat blade screwdriver, remove the bottom brush
assembly cap through the access hole in the base and
the top brush assembly cap from the top of the motor.
Gently pry the brush assemblies out using a small screw
drivier, point of a nail, or paper clip.
■ If one motor brush is worn down shorter than 1/4 in. (6
mm), replace both motor brushes. Do not replace one
side without replacing the other. Make sure curvature of
brush matches curvature of motor and that the motor
brush moves freely in brush tube. Use the blunt end of
something thin (eraser end of pencil, etc.) to push the
motor brush into the tube until it stays.
■ Make sure the motor brush cap is oriented correctly
(straight). Tighten motor brush cap using a hand
powered screwdriver only. Do not overtighten.
WARNING:
If the power cord is worn, cut, or damaged in any way,
have it replaced immediately by a qualified service
technician. Failure to do so could result in serious personal
injury.

EXTENSION CORD CAUTION
When using a power tool at a considerable distance from a power
source, be sure to use an extension cord that has the capacity to
handle the current the tool will draw. An undersized cord will
cause a drop in line voltage, resulting in overheating and loss of
power. Use the chart to determine the minimum wire size required in an extension cord. Only round jacketed cords should be
used.
When working with a tool outdoors, use an extension cord that is
designed for outside use. This is indicated by the letters "WA" on
the cord's jacket.
Before using any extension cord, inspect it for loose or exposed
wires and cut or worn insulation.
