ELECTRICAL CONNECTION  
EXTENSION CORDS  
Use only 3-wire extension cords that have 3-prong ground-  
ing 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.  
YourRyobiScrollSawispoweredbyaprecisionbuiltelectric  
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  
reducetheriskofelectricshock. Thistoolisequippedwithan  
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.

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.  
Donotmodifytheplugprovided. Ifitwillnotfittheoutlet, have  
the proper outlet installed by a qualified electrician. Improper  
connectionoftheequipment-groundingconductorcanresult  
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 termi-  
nal.  
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.  
Check with a qualified electrician or service personnel if the  
groundinginstructionsarenotcompletelyunderstood, orifin  
doubt as to whether the tool is properly grounded.  
Repair or replace a damaged or worn cord immediately.

CLAMPING SCROLL SAW TO WORKBENCH  
See Figure 5.  
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.  
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.  
MOUNTING SCROLL SAW TO WORKBENCH  
WARNING:  
To avoid serious personal injury from unexpected tool  
movement, always securely mount scroll saw to a  
workbench.  
I Mountsawtoboardusingholesinsawbaseasatemplate  
for hole pattern. Locate and mark the holes where scroll  
saw is to be mounted.  
I Follow last three steps in previous section called  
Mounting Scroll Saw to 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.  
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.  
I 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 accom-  
modate the saw base, washers, nuts, and the thickness  
of the workbench.  
Note: It may be necessary to countersink washers and nuts  
on the bottom side of mounting board.  
I 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.  
I Drill four holes through the workbench.  
I Place scroll saw on workbench aligning holes in the saw  
base with the holes drilled in the workbench.  
I 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 move-  
ment during use can result. If any tipping or walking is noted,  
secure workbench or supporting surface before beginning  
cutting operations.

OPERATION  
BASIC OPERATION OF THE SCROLL SAW  
WARNING:  
Before removing loose pieces from the table, turn saw off  
and wait for all moving parts to stop to avoid serious  
personal injury.  
Before starting a cut, watch the saw run. If you experience  
excessivevibrationorunusualnoise,stopimmediately.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.  
AVOIDING INJURY  
I 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.  
I Bolt saw to the support surface to prevent slipping,  
walking or sliding during operations like cutting long,  
heavy boards.  
I Turn saw off, remove switch key, and unplug cord from  
the power source before moving the saw.  
I Do not remove jammed cutoff pieces until blade has come  
CUTTING PROCEDURES  
I 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.  
I Plan the way you will hold the workpiece from start to  
finish.  
I Keep your hands away from the blade. Do not hand hold

to a full and complete stop.  
I Hold the workpiece firmly against the saw table.  
I Choose the right size and style blade for the material  
and type of cut you plan to do.  
I The blade teeth cut material only on the down stroke.  
I Use only recommended accessories.  
I Use gentle pressure and both hands when feeding the  
I With the exception of the workpiece and related support  
devises, clear everything off the saw table before turning  
the saw on.  
I 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  
work into the blade. Do not force the work.  
I 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.  
I 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.  
I 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.  
I Use extra supports (tables, saw horses, blocks, etc.)  
when cutting large, small or awkward workpieces.  
I Wait until the saw has come to a full and complete stop.  
I 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.  
I Place the switch in the OFF position, remove the switch  
key from the switch assembly. Store key in a safe place.  
I 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.  
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:

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.

BLADE INFORMATION  
I Scroll saw blades wear out and must be replaced fre-  
quently for best cutting results. Scroll saw blades gener-  
ally stay sharp for 1/2 hour to 2 hours of cutting, depend-  
ing on type of material and speed of operation.  
I In cutting wood, best results are achieved when cutting  
wood less than one inch thick.  
I 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.  
OFF  
ON  
I 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.  
TO  
INCREASE  
TO  
DECREASE  
• Wider blades cannot cut curves as tight or as small as  
thinner blades.  
I Blades wear faster when:  
Fig. 12  
• 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.  
I 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 approxi-  
mately 400 SPM.  
I To increase the strokes per minute, turn the variable  
speed knob clockwise or to the right.  
I To decrease the strokes per minute, turn the variable  
speed knob counterclockwise or to the left.

INTERIOR SCROLL CUTTING  
See Figure 13.  
Fig. 13  
I 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.  
I To make interior cuts in the workpiece, remove the scroll  
saw blade as explained in the section on Installing  
Blades on page 13.  
WARNING:  
To avoid possible, serious personal injury, do not cut  
more than one loose piece of material at a time.  
I Drill a 1/4 in. (6 mm) hole in the workpiece.  
I Place the workpiece on the saw table with the drilled hole  
WARNING:  
over the access hole in the table.  
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.  
I Install blade through the hole in the workpiece; adjust the  
drop foot and blade tension.  
I 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.  
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  
betweeneachpieceorbywrappingmaskingtapearoundthe  
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  
MOTOR BRUSHES  
See Figure 16.  
WARNING:  
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.  
When servicing, use only identical Ryobi replacement  
parts. Use of any other part may create a hazard or cause  
product damage.  
I Unplug the saw from the power source.  
GENERAL MAINTENANCE  
I Keep your scroll saw clean.  
I Carefully place the saw on its side exposing the under-  
side of the saw housing.  
I 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.  
I 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.  
I Do not allow pitch to accumulate on the saw table. Clean  
with gum and pitch remover.  
I 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.  
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.  
I Carefully place the saw on its side as shown in Figure 15.  
Remove the rubber cap from the upper and the lower arm  
of the saw.  
I Make sure the motor brush cap is oriented correctly  
(straight). Tighten motor brush cap using a hand  
powered screwdriver only. Do not overtighten.  
I 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.
