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
plate 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.
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 plate
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.
WARNING:
Do not attempt to use this tool until you have read
thoroughly and understand completely the
operator's manual. Pay close attention to the safety
rules, including Dangers, Warnings, and Cautions.
If you use this tool properly and only for what it is
intended, you will enjoy years of safe, reliable
service.
Look for this symbol to point out important safety precautions. It
means attention!!! Your safety is involved.

GENERAL SAFETY RULES
WARNING:
Read and understand all instructions. Failure to fol-
low all instructions listed below, may result in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases,
or dust. Power tools create sparks which may ignite the
dust or fumes.
Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug
will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any
way. Double insulation eliminates the need for the
three-wire grounded power cord and grounded power
supply system.
Avoid body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerators. There is
an increased risk of electric shock if your body is grounded.
Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges, or moving parts.
Replace damaged cords immediately. Damaged cords
increase the risk of electric shock.
When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use
tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while oper-
ating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jew-
elry. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jew-
elry, or long hair can be caught in moving parts.
Avoid accidental starting. Be sure switch is off be-
fore plugging in. Carrying tools with your finger on the
switch or plugging in tools that have the switch on invites
accidents.
Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
Use clamps or other practical way to secure and sup-
port the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may
lead to loss of control.
Do not force tool. Use the correct tool for your appli-
cation. The correct tool will do the job better and safer at
the rate for which it is designed.
Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from power source before mak-
ing any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
Store idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools with sharp cutting edges
are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used
on another tool.
Keep the tool and its handle 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 strong solvents to clean your tool. Following
this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.

GENERAL SAFETY RULES
SERVICE
Tool service must be performed only by qualified re-
pair personnel. Service or maintenance performed by
unqualified personnel may result in a risk of injury.
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will make exposed metal parts of the cutting
tool “live” and shock the operator.
ADDITIONAL SAFETY RULES
Know your power tool. Read operator’s manual care-
fully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
Always wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk of
serious personal injury.
Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
Protect your hearing. Wear hearing protection dur-
ing extended periods of operation. Following this rule
will reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest Authorized Service Center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
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 should be properly repaired or
replaced by an authorized service center. Following
this rule will reduce the risk of shock, fire, or serious injury.
Do not abuse cord. Never carry the tool by the cord
or yank it to disconnect it from the receptacle. Keep
cord away from heat, oil, and sharp edges. Following
this rule will reduce the risk of electric shock or fire.
When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to
follow Maintenance Instructions may create a risk of shock
or injury.
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. A wire gage size (A.W.G.) of at least 14 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. An un-
dersized cord will cause a drop in line voltage resulting in
loss of power and overheating.
Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
Drugs, alcohol, medication. Do not operate tool while
under the influence of drugs, alcohol, or any medication. Following this rule will reduce the risk of electric
shock, fire, or serious personal injury.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this tool. 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
DOUBLE INSULATION
Your Ryobi power tool is double insulated. This means you
are separated from the tool's electrical system by two complete
sets of electrical insulation. This extra layer of insulation is
intended to protect the user from electrical shock due to a
break in the wiring insulation. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need to
be grounded.
Important: Servicing of a tool with double
insulation requires extreme care and knowledge
of the system and should be performed only by
a qualified technician. For service, we suggest
you return the tool to your nearest authorized
service center for repair. When servicing, use
original factory replacement parts .
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.
ELECTRICAL CONNECTION
This tool 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 our tool does not
operate when plugged into an outlet, double-check the
power supply.
EXTENSION CORDS
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.

DEPTH OF CUT ADJUSTMENTS
Your plate joiner can be adjusted to three standard cutting
depths to accommodate three standard size biscuits — #0,
#10, and #20. Adjustments are made by engaging slots on
depth adjustment knob with tabs on rear base assembly. For
example, when using a #0 size biscuit, rotate the depth
adjustment knob to the slot marked 0. When using a #10 size
biscuit, rotate the depth adjustment knob to the slot marked
10, and when using a #20 size biscuit rotate the depth
adjustment knob to the slot marked 20. See Figure 3.
TO SET DEPTH ADJUSTMENT KNOB
Unplug your plate joiner.
WARNING:
Failure to unplug your plate joiner could result in
accidental starting causing possible serious personal
injury.
Pull knurled adjustment knob and jam nut in the direction
of the arrow shown in figure 3.
NOTE: Knob and jam nut are spring loaded, therefore
pulling them in the direction of the arrow shown puts
pressure on the spring and releases pressure from the
depth adjustment knob.
Rotate depth adjustment knob until desired slot setting
aligns with tabs on rear base assembly — 0, 10, or 20.
Next release knurled adjustment knob and jam nut
applying pressure from spring on depth adjustment
knob.
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.
TO MAKE FINE ADJUSTMENTS

OPERATION
WARNING:
Always wear safety goggles or safety glasses with side
shields when operating tools. Failure to do so could
result in objects being thrown into your eyes, resulting in
possible serious injury.
A variety of spline joints can be made using your plate 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 #0 biscuits should be used for miter cuts
in 3/4 in. materials. The larger biscuits should be used for
edge-to-edge joinery.
When joining 1-1/2 in. thick materials, stack two biscuits, one
above the other. For example, joining 2 in. x 4 in. dressed
lumber. See Figure 9. When joining even thicker materials,
use additional biscuits, stacked above each other.
When making edge-to-edge joints for tabletops, workbenches,
cutting boards, etc. the more biscuits you use, the stronger
the joint will be.
The following sections illustrate how to make various spline
joints using your plate 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.
Plug your plate joiner into power supply and prepare to
make your first cut. Grasp and hold your plate joiner
securely with both hands by the front and rear handles
as shown on page 3.
Place the fence against the board and align the indicator
marks on the fence with the centerline mark(s) on the
board. See Figure 7.
Depress the switch trigger to turn the power on your
plate joiner, then push it 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.
INDICATOR MARK (S)
HOW TO MAKE EDGE-TO-EDGE JOINTS
Unplug your plate 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.
NOTE: Mark the edges 2 in. from the ends of workpieces.
The joint will be stronger if you use multiple biscuits
placed close together.
Loosen height adjustment knobs and set fence angle at
90°.
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.

OPERATION
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.
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 plate 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.
Loosen height adjustment knobs and set fence angle at
90°.
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 plate joiner into power supply and prepare to
make your first cut. Grasp and hold your plate joiner
securely with both hands by the front and rear handles.
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 to turn the power on your plate
joiner, then push it 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 cutting the slot in the mating
workpiece.
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 9.
Clamp workpieces together until the glue sets up.

OPERATION
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.
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. See Figure 11.
HOW TO MAKE T- JOINTS
Unplug your plate 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 plate joiner into power supply and cut slots in
all boards that require end slots. See Figure 13. Follow
procedures explained in "Edge-To-Edge Joints". Set
fence angle at 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 adjust the fence on your plate joiner in
order to cut slots into the face of the vertical board.
TO ADJUST FENCE:
Unplug your plate joiner.
Loosen height adjusting knobs and set fence angle at 0°,
set fence height at desired dimension on the scale then
retighten height adjustment knobs securely. See Figure
14. Next, select the correct depth of cut setting for the
biscuit size you plan to use, clamp workpiece securely,
and cut each slot at the marked centerline intersection.

OPERATION
Place your plate joiner on vertical board as shown in
figure 15 and align indicator marks on base assembly
with centerline on vertical board.
Place a straight piece of wood on the vertical board and
securely clamp it flush against the base assembly. This
piece of wood is used for a fence or guide. It must be
square with the sides of the vertical board and parallel
with the centerline.
Align centerline on bottom of base assembly with marked
intersection for biscuit slot.
Plug your plate joiner into power supply and prepare to
cut slot.
Depress the switch trigger to turn the power on your plate
joiner, then push it down 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.
T-JOINTS
Repeat this procedure for cutting all required slots in
vertical boards.
Once all 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

MITER JOINTS
See Figures 16-19.
There are two types of miter joints that can be made using
biscuits: flat miters and edge miters. Flat miters are used
when making picture frames. Edge miters are used when
making boxes or things where you don't want to show the
end grain of the wood.
NOTE: Butt joints show the end grain in wood.
HOW TO MAKE FLAT MITER JOINTS
Unplug your plate joiner.
WARNING:
Failure to unplug your plate joiner could result in accidental
starting causing possible serious personal injury.
Place the pieces of wood to be joined on a level workbench
as shown in figure 16.
Using a combination square, draw a line through the
center of each joint perpendicular to the mitered edges.
Set fence angle at 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, and clamp
workpiece securely.

DUSTLESS FEATURE
See Figure 20.
The dust bag located on the rear of your plate joiner provides
a dust collection system. Wood particles are drawn up
through a tunnel in the base and collect in the dust bag during
cutting operations. For more efficient operation, empty dust
bag when half full.
Do not connect plate joiner to power supply before installing
dust bag.
WARNING:
To prevent the possibility of sawdust or foreign objects
being thrown into your face and eyes, never attempt to
use your plate joiner without dust bag properly installed.
Sawdust or foreign objects being thrown into your face
and eyes could result in possible serious injury.
TO INSTALL DUST BAG
The dust bag can be installed by inserting the dust bag
adaptor inside the blower exhaust. See Figure 20.
TO EMPTY DUST BAG
Remove dust bag from plate joiner, remove retainer strip and
shake out dust. Occasionally turn the dust bag inside out and
brush the accumulation of dust from the inside of the bag.
This will permit the air to flow through the bag better.

When electric tools are used on fiberglass it has been
found that they are subject to accelerated wear and possible
premature failure, as the fiberglass chips and grindings are
highly abrasive to bearings, brushes, commutator, etc.
Consequently it is not recommended that this tool be used
for extended work on any fiberglass material. During any
use on fiberglass it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
