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, par-
ticle 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 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.
INTRODUCTION
Lookforthissymboltopointoutimportantsafetyprecautions.
It means attention!!! Your safety is involved.
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,

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
heightadjustmentknobs,the fencecanberemovedthrough

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
centerofthe blade.Theheightof thefenceat 45°can beset
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.

marks on the fence with the centerline mark(s) on the
board. See Figure 7.
■Depress the switch trigger and let the motor build to its
maximumspeed,thengraduallypushbiscuitjoinerforward
to extend the blade into the wood.
■When the base assembly bottoms out against the depth
ofcutadjustmentknobsetting,pullbackreleasingpressure
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.
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 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
mitercuts insmall, thinmaterials. Thelarger biscuitsshould
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. When joining even thicker materials, use
additional biscuits, stacked above each other.
Whenmakingedge-to-edgejointsthemorebiscuitsyouuse,
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.
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.
■Selectthecorrectdepthofcutsettingtomatch thebiscuit
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.

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.
■Selectthecorrectdepthofcutsettingtomatch thebiscuit

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.

■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.

■Clamp workpieces together until the glue sets up.
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.
Keepingthisoneexceptioninmind,theprocedureforcutting
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
proceduresforcuttingbuttjoints,andcuttheslotsintheends
of the rails. Next you would raise the fence 1/4 in. to the
desired offset and cut the slots in the legs.

T- JOINT
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.
See Figure 11.
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.
See Figure 13. Follow
proceduresexplainedin"Edge-To-EdgeJoints".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
slideitdownthefrontbaseuntilitcanberemovedthrough
the key hole slots. See Figure 14. Next, select the correct
depth of cut setting for the biscuit size you plan to use,
clampworkpiecesecurely,andcuteachslotatthemarked
centerline intersection.
WARNING:
When the fence is removed, the cutter may be exposed.
Use extreme caution to avoid serious personal injury.
■Place your biscuit joiner on vertical board as shown in
figure 15 and align indicator marks on bottom shoe with
centerline on vertical board.
■Place a straight piece of wood on the vertical board and

the fence on the front base by reversing "TO REMOVE
FENCE" procedure. Place height adjustment knob bolts in
key hole slots and align bolt heads with the slots on back of
front base. Slide fence up the front base to desired depth of
cut. Tighten height adjustment knobs securely.
MITER JOINTS
See Figures16-18.
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. Butt joints show the end grain in
wood.
HOW TO MAKE FLAT MITER JOINTS
■Unplug your detail biscuit joiner.
WARNING:
Failure to unplug your detail biscuit joiner could result in
accidentalstarting causing possibleseriouspersonal injury.
■Place the pieces of wood to be joined on a level

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.
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.
OPTIONAL ACCESSORIES
