GENERAL POWER TOOL SAFETY WARNINGS
Read all safety warnings and all instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference. The term “power tool” in
the warnings refers to your mains operated (corded) power tool or battery-operated
(cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerator. There is an increased risk of electric shock if your body
is earthed or grounded.
• Do not 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 for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges and moving parts.
Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk
of electric shock.
• If operating a power tool in a damp location is unavoidable,use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating
a power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the o-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools
that have the switch on invites accidents.

1261-000

• Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
• If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which
it was designed.
• Do not use the power tool if the switch does not turn it on and o. Any power tool
that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the
power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may aect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations dierent from those intended
could result in a hazardous situation.
SERVICE
• Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.

SPECIFIC SAFETY RULES FOR BISCUIT JOINERS
WARNING
Serious cuts, amputation, or death can occur from contact with rotating saw blade
during operation. Workpieces, broken blades, or flying particles thrown by blade
can blind or strike operators or bystanders with great force. To reduce the risk of
these hazards, operator and bystanders MUST completely heed the hazards and
warnings below.
PROPERLY MAINTAIN BLADE. Always ensure Biscuit Joiner blade is sharp,
undamaged, and tightly attached before each use.
AVOID TOUCHING BLADE. Never place hands or fingers between work- piece
and blade, and do not perform a cut while supporting workpiece with one hand or
balancing it on a leg or any other body part.
PROPERLY SUPPORT WORKPIECE. Properly support all workpieces to reduce
risk of workpiece and tool slipping during cutting operation. Place workpiece on
supports or workbench and clamp in place.
USE BISCUIT JOINER FOR INTENDED PURPOSE. Only use Biscuit Joiner on
wood and wood-based products. Do not attempt to use this tool for any operation
other than biscuit joining.
USE RECOMMENDED BLADES. Only use blades rated for speeds greater than
11,000 RPM. Blades not rated for this speed may fly apart. Only use blades that
meet the specifications listed in the manual. Do not use blades with dierent
diameters or arbor hole shapes/sizes. They will rotate irregularly, causing ejection of
blade fragments and tool damage.
PROPERLY INSTALL COMPONENTS. Ensure sliding base, faceplate, and fence
are in place and operating correctly before each cut.
STARTING AND STOPPING CUTS. Allow blade to reach full speed before cutting.
Always allow blade to come to a complete stop before setting tool down.
MAINTAIN CONTROL OF TOOL. Hold tool with both hands and do not allow the
Biscuit Joiner base to shift while performing plunge cuts. Always use the guard. The
guard protects the operator from broken blade fragments and unintentional contact
with the blade.
• Hold the power tool by its insulated gripping surfaces, because the blade may
contact its own cord. Cutting a “live” wire may make exposed metal parts of the
power tool “live” and could give the operator an electric shock.
• Always use correctly sized blades with the fitting mounting bore. Blades that do
not fit to the mounting components of the biscuit joiner rotate irregularly and
lead to loss of control.
• Do not use blunt or damaged blade. Blunt or damaged blades cause increased
friction, can become jammed and lead to imbalance.
• Before putting into operation, check that the guard is retracting freely.
• Always wear hearing protection when operating the biscuit joiner.

ADJUSTING CUTTING DEPTH
1. DISCONNECT TOOL FROM POWER!
2. Rotate depth indicator until position "10"
is aligned with arrow mark.
3. Push forward on auxiliary handle until depth
stop contacts depth indicator and measure
length of exposed blade from blade tooth tip
to sliding base.
Note: Rotate saw blade until blade tooth tip is
centered at the maximum distance from the
sliding base.
4. Verify depth measurement as follows:
• If measurement equals 10mm, the cutting depth is properly calibrated.
• If measurement does not equal 10mm, loosen depth stop lock nut
(see Figure 11).
WARNING:
Failure to correctly adjust the cutting depth could cause damage to the workpiece.
Note: Always make a trial cut on scrap material to confirm the settings and reduce
or extend depth stop until measurement equals 10mm. Tighten depth stop lock nut
once depth is reached.
ADJUSTING CUTTING ANGLE
The faceplate can be adjusted between 0° and 90°,
though 90° is the most common angle of cut for
biscuit joining. Certain applications, such as joining
beveled edges, require the biscuit to be inserted at
Note: Ball and groove detents on the angle scale
are provided to set the angle at 0°, 45°, and 90°.

WORKPIECE PREPARATION
Properly mark your workpieces to avoid incorrect biscuit placement
and wasted material.
The following example illustrates a typical biscuit joining layout.
LAYING OUT CUTS
1. Place edges of (2) workpieces flush against
each other on a smooth, flat surface. Verify
board ends line up.
2. Place marks 2 1/2”- 3” from each end of one
board. Note: If distance between marks is
greater than 6", place additional marks at
4"-6" intervals (see Figure 14).
3. Use a square to draw layout lines across
boards through marks, then make
registration marks on edge of each boar
to ensure correct edge is cut
(see Figure 15).
SECURING WORKPIECE
Your workpiece must be properly secured
before making cuts. Cutting biscuit grooves with
a biscuit joiner places pressure on the edge of
the workpiece, which can cause an improperly
secured workpiece to shift on the workbench,
resulting in personal injury or damage to the
tool or workpiece.
Use clamps to secure workpiece on work-
bench. Edge of workpiece should hang slightly
over edge of workbench (see Figure 16).
Note: Clamps should be placed at least 3"
from any cut marks to prevent interference with
joiner.

TO CUT BISCUIT GROOVES
1. Place fence on workpiece so front groove and
rear groove line up with layout line, as shown
in Figure 17. Make sure faceplate contacts
edge of workpiece.
2. Turn biscuit joiner ON and allow motor to
reach full speed.
3. With both hands holding tool, slowly push
blade into workpiece, as shown in Figure 18,
making sure joiner grooves remain aligned
with layout line on workpiece, as described
in Step 1.
4. Once blade reaches full depth, slide joiner
body backward, allowing blade to retract
into base plate.
5. Turn joiner OFF and wait for motor to come
to a complete stop before setting tool down.
GLUING BISCUITS
Once all biscuit grooves have been cut, test-fit biscuits with a "dry fit" prior to
the glue-up. Place a biscuit in each groove, and fit the pieces together to check
for proper alignment.
Once a proper fit is verified, apply glue to workpiece edges and grooves, insert
biscuits into grooves, then clamp according to the needs of the material and
the glue manufacturer's instructions.
CHANGING BLADE
This tool accepts 4" blades with either a 20mm or 22mm bore, depending
on the position of the inner flange.
ATTENTION
To reduce risk of injury, always disconnect power from joiner before changing
blades. Since blade is sharp, use extra care and wear gloves when installing it.

MAINTENANCE
ATTENTION
Always DISCONNECT POWER before servicing, adjusting, or doing maintenance
to reduce risk of accidental injury or electrocution.
For optimum performance from this tool, routinely check the condition of the
following items and repair or replace as necessary.
• Loose bolts
• Damaged bits
• Worn or damaged wires
• Any other unsafe condition
CLEANING
Use a brush and a shop vacuum to remove wood chips and other debris from the
tool, particularly from around the blade slot on the sliding base. Never blow o
the tool with compressed air, as this could force wood chips deeper into the motor
vents. Use a clean cloth to wipe away any dust remaining after each operation.
Note: DO NOT use caustic cleaners on plastic parts. If dry cleaning is insucient,
a mild detergent on a damp cloth is recommended.
Keep water away from tool at all times.
LUBRICATION
Periodically lubricate all moving parts with a light
machine oil as needed. Place a drop of oil on the
guide rails on both sides of the sliding base (see
Figure 27), then slide the base back and forth,
working the oil across the rails. Use a clean rag to
wipe o any excess oil, which can collect sawdust
or stain the workpiece.
REPLACING BRUSHES
This tool is equipped with a universal motor that uses two carbon brushes to
transmit electrical current inside the motor. These brushes are considered to be
regular "wear items" or "consumables" that will need to be replaced during the life
of the motor. The frequency of required replacement is related to how much the
motor is used and how hard it is pushed. Replace both carbon brushes at the same
time when the motor no longer reaches full power, or when the brushes measure
less than 1/4" long (new brushes are 5/8" long).
