DOUBLE INSULATION
Double insulation is a concept in safety, in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be grounded.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the tool's
internal wiring. Observe all normal safety precautions
related to avoiding electrical shock.
IMPORTANT
Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should
be performed only by a qualified service technician.
For service we suggest you return the tool to your
nearest RYOBI AUTHORIZED SERVICE CENTER for
repair. When servicing use only identical Ryobi
replacement parts.
WARNING:
Do not attempt to operate this tool until you have read
thoroughly and understand completely all instructions,
safety rules, etc. contained in this manual. Failure to
comply can result in accidents involving fire, electric
shock, or serious personal injury. Save owner's manual
and review frequently for continuing safe operation, and
instructing others who may use this tool.

Don't use power tools in damp or wet locations
or expose to rain. Keep work area well lit.
5. KEEP CHILDREN AND VISITORS AWAY.
All visitors should wear safety glasses and be
kept a safe distance from work area. Do not let
visitors contact tool or extension cord.
6. STORE IDLE TOOLS. When not in use tools
should be stored in a dry, high or locked-up
place – out of the reach of children.
14. SECURE WORK. Use clamps or a vise to
hold work. It's safer than using your hand and
it frees both hands to operate tool.
15. DON'T OVERREACH. Keep proper footing
and balance at all times. Do not use on a
ladder or unstable support.
16. MAINTAIN TOOLS WITH CARE. Keep tools
sharp at all times, and clean for best and
safest performance. Follow instructions for
lubricating and changing accessories.
17. DISCONNECT TOOLS. When not in use,
before servicing, or when changing
attachments, blades, bits, cutters, etc., all
tools should be disconnected.
18. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see
that keys and adjusting wrenches are removed
from tool before turning it on.
19. AVOID ACCIDENTAL STARTING. Don't
carry plugged-in tool with finger on switch. Be
sure switch is off when plugging in.
7. DON'T FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.
8. USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.
Don't use tool for purpose not intended – for
example – Don't use a circular saw for cutting
tree limbs or logs.
9. DRESS PROPERLY. Do not wear loose
clothing or jewelry. They can be caught in
moving parts. Rubber gloves and nonskid
footwear are recommended when working
outdoors. Also, wear protective hair covering
to contain long hair and keep it from being
drawn into air vents.
10. ALWAYS WEAR SAFETY GLASSES WITH
SIDE SHIELDS. Everyday eyeglasses have
only impact resistant lenses; they are NOT
safety glasses.
11. PROTECT YOUR LUNGS. Wear a face or
dust mask if operation is dusty.
12. PROTECT YOUR HEARING. Wear hearing
protection during extended periods of
operation.
13. DON'T ABUSE CORD. Never carry tool by
cord or yank it to disconnect from receptacle.
Keep cord from heat, oil, and sharp edges.
20. 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 gage size (A.W.G.) of at
least 16 is recommended for an extension
cord 50 feet or less in length. A cord exceeding
100 feet is not recommended. If in doubt, use
the next heavier gage. The smaller the gage
number, the heavier the cord.
21. OUTDOOR USE EXTENSION CORDS.
When tool is used outdoors, use only extension
cords intended for use outdoors. Outdoor
approved cords are marked with the suffix WA, for example - SJTW-A or SJOW-A.
22. KEEP BLADES CLEAN AND SHARP. Sharp
blades minimize stalling and kickback.
23. KEEP HANDS AWAY FROM CUTTING
AREA. Keep hands away from blades. Do not
reach underneath work while blade is rotating.
WARNING: BLADES COAST AFTER TURN
OFF.
24. NEVER USE IN AN EXPLOSIVE
ATMOSPHERE. Normal sparking of the motor
could ignite flammable liquids, gases, or
fumes.

INTRODUCTION
Spline joinery is one of the strongest methods of joinery
used in woodworking. When glue is properly applied to a
spline and to the joint area of the wood pieces being
connected, a large surface area receives the adhesion
properties of the glue. This forms a very strong joint.
Traditional spline joinery requires cutting slots with a router
or table saw. Small, thin strips of wood must then be cut to
fit inside the slots and act as splines.
Newer methods of spline joinery use a plate or biscuit
joiner to cut precise mating oval slots in adjoining boards.
Your new biscuit joiner is a fast, simple, and accurate
plunge cutting tool that can be used for this purpose. It can
be used to cut slots in hardwood, softwood, plywood, particle board, and other pressed woods.
WARNING:
WEAR
YOUR
SAFETY
FORESIGHT IS BETTER
GLASSES
THAN NO SIGHT
The operation of any biscuit joiner can result in foreign objects being thrown into your
eyes, which can result in severe eye damage. Before beginning power tool operation,
always wear safety goggles or safety glasses with side shields and a full face shield
when needed. We recommend Wide Vision Safety Mask for use over eyeglasses or
standard safety glasses with side shields.
Football shaped wafers, called biscuits, are then placed
inside the slots with glue and used to help line up adjoining
surfaces. When a water based glue is used, the biscuits
swell in the joint, making an extremely strong and firm
bond. White glue, yellow glue, carpenters glue, hide glue,
and aliphatic resin glue are examples of water based glues.
This bonding technique has traditionally been limited to
making edge-to-edge joints. However, with the use of your
new biscuit joiner, biscuits can now be easily used to
connect butt, miter, and T-joints. Biscuit joining can be as
strong as mortise and tenon, tongue and groove, standard
spline, and doweled joints. In most cases the material
around the biscuit will break before the biscuit itself will
break. A greater surface area is exposed to glue in a biscuit
joint, making the seams stronger.
Look for this symbol to point out important safety precautions.
It means attention!!! Your safety is involved.

FEATURES
Your detail biscuit joiner has been designed for making fast,
accurate, and simple plunge cuts in wood, etc. so that
biscuits can be used to join two or more boards together.
When used properly and only for what it is intended, this
versatile tool will give you years of trouble-free performance.
It is professionally engineered, but its ease of operation
allows the amateur to produce beautiful and precise work.
#R1 = 7/32 in. x 5/8 in.
SWITCH
To turn your biscuit joiner ON, depress the switch trigger.
Release switch trigger to turn your biscuit joiner OFF.
MOTOR
Your biscuit joiner has a powerful motor with sufficient power
to handle tough cutting jobs. It develops a no load speed of
19,000 RPM.
BLADE
Your biscuit joiner has a 1-1/2 in. (38 mm) 6 tooth blade for
cutting biscuit slots.
BISCUITS
See Figure 1.
Biscuits are available in three standard sizes:
#R1 (7/32 in. x 5/8 in.)
#R2 (9/32 in. x 3/4 in.)
#R3 (1/2 in. x 1 in.)
NOTE: Store biscuits in a dry place because they swell
rapidly upon contact with water-based woodworking glues.
REVERSIBLE FENCE FOR 45° AND 90° CUTS
Your biscuit joiner has a reversible fence. By loosening the
height adjustment knobs, the fence can be removed through
key hole slots. Once removed, it can be rotated 180° changing
the angle of cut from 90° to 45° or vice versa. The height of
the fence at 90° can be set between 0 to 3/4 in. from the
center of the blade. The height of the fence at 45° can be set
between 5/16 in. to 13/16 in. from the center of the blade.
The fence should always be used to guide and balance your
biscuit joiner, providing ease of operation and maintaining
safe control.
NONSKID BACKING PAD
The fence on your biscuit joiner is padded with a nonskid
backing pad to hold it stationary against the workpiece. It
helps prevent skidding when making cuts. It also prevents
marring of the workpiece from biscuit joiner when cutting.
INDICATOR MARKS
Centerline and line of cut indicator marks have been provided
on your biscuit joiner.
See Figure 2.

APPLICATIONS
(Use only for the purpose listed below)
■ Cutting precise mating oval slots in hardwood, softwood,
plywood, particle board, etc. for spline joinery applications.
ELECTRICAL CONNECTION
Your biscuit joiner has a precision built electric motor. It
should be connected to a power supply that is 120 volts,
60 Hz, 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 your biscuit joiner does not operate when plugged into an
outlet, double-check the power supply.
DEPTH ADJUSTMENT KNOB
A spring loaded depth adjustment knob makes it possible to
make proper settings for three standard size biscuits. Fine
adjustments to the cutting depth can be made with a knurled
adjustment knob and jam nut located behind the depth
adjustment knob. Once the correct depth setting has been
made for one biscuit size, the other two depth settings will be
automatically set.

Make a test cut in a scrap piece of wood. Fit the correct size
biscuit into biscuit slot. If biscuit slot is too deep or too
shallow, fine adjustments to the depth setting can be made
by loosening knurled adjustment knob and making fine
adjustments with the jam nut. Turning jam nut forward will cut
shallow biscuit slots. Turning jam nut backwards will cut
deeper biscuit slots. The biscuit slot should be deep enough
to allow slightly more than one-half of the biscuit into the slot.
This extra room allows for proper alignment of the wood
being joined.

WARNING:
Always wear safety goggles or safety glasses with side

result in objects being thrown into your eyes, resulting in
possible serious injury.
A variety of spline joints can be made using your biscuit
joiner. The number and size biscuits needed for each joint
depends on the thickness of the wood and the length of the
joint. In general, the small #R1 biscuits should be used for
miter cuts in small, thin materials. The larger biscuits should
be used for edge-to-edge joinery.
When joining thick materials, stack two biscuits, one above
the other. For example, joining 2 in. x 4 in. dressed lumber.
See Figure 9.
additional biscuits, stacked above each other.
When making edge-to-edge joints the more biscuits you use,
the stronger the joint will be.
The following sections illustrate how to make various spline
joints using your biscuit joiner.
EDGE-TO-EDGE JOINTS
See Figures 7 and 8.
Edge-to-edge joinery is one of the most basic and easiest
joints to construct. In general, two basic adjustments have
to be made for all biscuit joinery applications. One is the
depth of cut and the other is the location of the cut.
When joining even thicker materials, use

HOW TO MAKE EDGE-TO-EDGE JOINTS
■ Unplug your detail biscuit joiner.
■ Prepare the workpieces by laying them side by side on a
workbench in the order in which they will be assembled.
■ Using a square, determine the location of each biscuit
spline joint and mark the center of each joint by drawing
a line across each workpiece. Mark the edges 1 in. from
the ends of workpieces. The joint will be stronger if you
use multiple biscuits placed close together.
■ Set fence angle at 90°.
■ Loosen height adjustment knobs, then pull and slide the
fence up or down until the indicator point is aligned with
the desired dimension on the scale. REMEMBER: The
scale indicates the height of the fence from the center of
blade.
■ Tighten height adjustment knobs securely.
■ Select the correct depth of cut setting to match the biscuit
size you are planning to use. We suggest that you make
a test cut in a scrap piece of wood from the same
workpiece if possible.
■ Clamp workpiece securely so that it will not move during
the cut.
■ Plug your biscuit joiner into power supply and prepare to
make your first cut. Grasp and hold your biscuit joiner
securely with both hands.

See Figure 7.
■ Depress the switch trigger and let the motor build to its
maximum speed, then gradually push biscuit joiner forward
to extend the blade into the wood.
■ When the base assembly bottoms out against the depth
of cut adjustment knob setting, pull back releasing pressure
on the spring. Blade will retract from biscuit slot.
■ Repeat this procedure for all desired biscuit slots.
■ Once all biscuit slots have been cut, place a biscuit in
each joint and dry assemble the workpieces. Make sure
each joint lines up and fits.
■ Finally, disassemble the workpieces and place a bead of
glue in each slot. Also, spread a bead of glue over the
entire surface of the joint. Reinsert the biscuits and
assemble the workpieces.
See Figure 8.
■ Clamp workpieces together until the glue sets up.
Page 11
OPERATION
BUTT JOINTS
See Figure 9.
A butt joint is one of the weakest joints in woodworking.
This type of joint is mating the end grain of one board with
the edge grain of another. The bonding of glue on this type
of surface is poor. However, by using biscuits you can
create a very strong joint that gives a mortise-and-tenon
effect.
HOW TO MAKE BUTT JOINTS
■ Unplug your detail biscuit joiner.
■ Place the two pieces of wood to be joined on a level
workbench. Align them against each other in the
arrangement in which they will be assembled.
■ Using a square, determine the location of each biscuit
spline joint and mark the center of each joint by drawing
a line across the edges of the two boards.
■ Set fence angle at 90°.
■ Loosen height adjustment knobs, then pull and slide the
fence up or down until the indicator point is aligned with
the desired dimension on the scale. REMEMBER: The
scale indicates the height of the fence from the center of
the blade.
■ Tighten height adjustment knobs securely.
■ Select the correct depth of cut setting to match the biscuit
size you are planning to use. We suggest that you make
a test cut in a scrap piece of wood from the same
workpiece if possible.
■ Clamp workpiece securely so that it will not move during
the cut.
■ Plug your biscuit joiner into power supply and prepare to

OFFSET BUTT JOINTS
See Figure 10.
The rails of a table or workbench are often offset from the
front of the table legs. When offsets are required, it is
necessary to cut the slots in the rails first, then re-adjust the
fence to cut the slots in the legs.
Keeping this one exception in mind, the procedure for cutting
offset butt joints is identical to the procedure for cutting butt
joints.
For example — If a 1/4 in. offset is desired, you would mark
the centerlines for cutting a butt joint as mentioned in the
procedures for cutting butt joints, and cut the slots in the ends
of the rails. Next you would raise the fence 1/4 in. to the
desired offset and cut the slots in the legs.

OPERATION
T- JOINTS
See Figures 11-15.
A T-joint is used when the end of a board is joined to the
face of another board as shown in figure 11. Attaching
shelves to bookcases and inner support braces to frames
are typical applications. Actual cutting of a T-joint is as
simple as any other cut. However, it is critical that you mark
the centerlines, mark the intersection points for each slot,
and cut each slot correctly.
HOW TO MAKE T- JOINTS
■ Unplug your detail biscuit joiner.
■ Place the two pieces of wood to be joined on a level
workbench as shown in figure 12. The inside face of the
vertical board should be facing up.
■ Determine the location of each biscuit joint and mark the
centerlines on each board as shown. The centerlines for
both boards must line-up with each other. Measure
carefully, these measurements must be accurate and
precise. TIP: Measure twice and cut once. In addition to
the centerlines lining up, the spacing of the biscuit slots
from side-to-side must also match.
■ Plug your biscuit joiner into power supply and cut slots in
all boards that require end slots.
procedures explained in "Edge-To-Edge Joints". Rotate
fence angle to 90°, set fence height at desired dimension
on the scale, select the correct depth of cut setting for the
biscuit size you plan to use, clamp workpiece securely,
then cut each slot at the marked centerline intersection.
■ Next, you must remove the fence from your biscuit joiner
in order to cut slots into the face of the vertical board.
TO REMOVE FENCE:
■ Unplug your detail biscuit joiner.
■ Loosen height adjustment knobs, pull fence forward and
slide it down the front base until it can be removed through
the key hole slots.

supplied in one of Ryobi's optional hinge kits. Jewelry boxes,
doors on clocks, recipe boxes, etc. are typical applications.
HOW TO MAKE HINGE JOINTS
■ Unplug your detail biscuit joiner.
■ Prepare the workpieces to be joined by laying them side
by side on a workbench in the order in which they will be
hinged.
■ Determine the location of each hinge joint and mark the
center of each joint by drawing a line across each workpiece.
■ Set fence angle at 90°.
■ Loosen height adjustment knobs, then pull and slide the
fence down the scale until the height indicator mark is set
at zero depth of cut. REMEMBER: The scale indicates the
height of the fence from the center of the blade, which is
approximately .050 of an inch.
■ Tighten height adjustment knobs securely.
■ Select the #3 depth of cut setting. We suggest that you
make a test cut in a scrap piece of wood from the same
workpiece if possible.
■ Clamp workpiece securely so that it will not move during
the cut.
■ Plug your biscuit joiner into power supply and prepare to
make your first cut. Grasp and hold your biscuit joiner
securely with both hands.
■ Place the fence against the board and align the indicator
marks on the fence with the centerline mark(s) on the
board.
■ Depress the switch trigger and let the motor build to its
maximum speed, then gradually push biscuit joiner forward
to extend the blade into the wood.
■ When the base assembly bottoms out against the depth
of cut adjustment knob setting, pull back releasing pressure
on the spring. Blade will retract from hinge slot.
