DW682K | DeWalt DW682K JOINTER GROOVER Type 4 instruction manual

4. POWER TOOL USE AND CARE
a. 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.
b. Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d. 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.
e. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other
condition that may affect the power tools operation. If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power tools.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
g. Use the power tool, accessories and tool bits etc., in accordance with these instructions and in the manner
intended for the particular type of power tool, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
5. SERVICE
a. 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.
Electrical Safety
The electric motor has been designed for one voltage only. Always check that the power supply corresponds to the
voltage on the rating plate. 230 V AC means your tool will operate on alternating current. As little as 10% lower voltage
can cause loss of power and can result in overheating. All DEWALT tools are factory tested; if this tool does not operate,
check the power supply. Your DEWALT tool is double insulated, therefore no earth wire is required.
• Young children and the infirm. This appliance is not intended for use by young children or infirm persons without
supervision. Young children should be supervised to ensure that they do not play with this appliance.
• Replacement of the supply cord. If the supply cord is damaged, it must be replaced by the manufacturer or an
authorised DEWALT Service Centre in order to avoid a hazard.

instructions in a safe place.
General Safety Rules
WARNING! Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or
serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool
or battery operated (cordless) power tool.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE
1. WORK AREA
a. Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. ELECTRICAL SAFETY
a. 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.
b. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
d. 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 or moving parts. Damaged or entangled cords increase the risk of electric
shock.
e. 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.
3. PERSONAL SAFETY
a. 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.
b. Use safety equipment. Always wear eye protection. Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with
your finger on the switch or plugging in power tools that have the switch on invites accidents.
d. 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.
e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in
unexpected situations.
f. 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.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are
connected and properly used. Use of these devices can reduce dust related hazards.
Additional Safety Warnings for Jointers
• Hold tool by insulated gripping surfaces when performing 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 tool “live” and shock
the operator.
• Saw blades must be rated for at lest the speed recommneded on the tool. Saw blades running over the rated
speed can fly apart and cause injury.
• ALWAYS use a guard. The guard protects the operator from broken saw blade fragments and unintentional contact
with the saw blade.
WARNING: ALWAYS wear approved protective safety equipment complying with the following standards:
• Eye protection: AS/NZS1337 Eye Protectors for Industrial Applications;
• Hearing protection: AS/NZS1270 Acoustics – Hearing Protection;
• Respiratory protection: AS/NZS1716 Respiratory Protective Devices.
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 (CCA).
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.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or
other injury. Always use AS/NZS standard approved respiratory protection appropriate for the dust exposure. Direct
particles away from face and body.
WARNING: We recommend the use of a residual current device with a residual current rating of 30mA or less.

Introduction
Examine Figure 1 and your plate joiner for a few minutes to become familiar with the various features and the names used
to describe them. The following sections will discuss the various controls and you will need to know where they are.
Overview
You have purchased a precision woodworking tool. The function of the plate joiner is to enable you to make extremely
strong and accurate joints in wood and wood by products.
The tool works by a plunging action to precisely cut crescent shaped slots for the placement of flat wooden dowels or
“biscuits” like those shown in Figure 2.
The various adjustments on the patented base/fence assembly will enable you to make virtually any biscuit joint
imaginable. The tool may be further enhanced by some simple jigs and fixtures that can be easily made. Some of the
more common biscuit joinery applications are shown in Figure 3 and are discussed in detail in the applications section
of this manual.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of injury, turn unit off and disconnect tool from power source before installing and
removing accessories, before adjusting or changing set-ups or when making repairs. Be sure the trigger switch is in
the OFF position. An accidental start-up can cause injury.
Switch
Your plate joiner has a trigger switch located on the underside, as shown in Figure 1. To turn the tool on, depress the
trigger. To turn the tool off, release the trigger. To lock the tool on for continuous operation, there is a lock on button
located at the rear of the tool just above the cord. When cutting always hold the tool with one hand on the switch handle
and one hand on the auxiliary handle. To lock the tool on, depress and hold the trigger as you depress the lock button.
Hold the lock button in as you gently release the trigger. The tool will continue to run. To turn the tool off from a locked
on condition, depress and release the trigger once.
Blade Replacement
In time your saw blade will wear out and need replacement. To remove the blade, follow the steps below.
1. Turn off and unplug the plate joiner.
2. Remove the four torx head screws from the bottom of the shoe, using the T20 torx screwdriver provided.
3. Rotate the shoe out of the way.
4. Use the spanner wrench provided to loosen (counterclockwise) the blade nut. Depress the spindle lock pin on the
top of the gear case to hold the spindle while you unscrew the nut.
5. Remove the blade and have it sharpened or replace it with a new one.
6. Reinstall the blade by reversing the steps above. Be sure blade teeth point counterclockwise as shown in Figure 4.
7. IMPORTANT: Always check the fine depth adjustment when sharpening or replacing the blade. Adjust if necessary.

1. EDGE TO EDGE JOINTS (Figure 16)
This is the simplest to make and most common joint for the plate joiner. Follow the steps below to produce this joint.
A. Prepare the workpieces and lay them on a work surface exactly as they are to be assembled.
B. Spacing biscuits 50 mm – 75 mm (2-3") in from the ends and 150 mm – 250 mm (6–10") apart, layout the
biscuit centers.
C. Set up the plate joiner by first selecting the proper depth setting. Set the fence to 90°. Set the height adjustment to
position the biscuit in the approximate center of the stock thickness.
D. Clamp the workpiece and position the tool so that the center indicator mark lines up with the first layout mark
(Figure 17). Turn on the tool and make the plunge cut. Retract the tool and release the trigger to turn the tool off.
Repeat for each layout mark.
E. Glue, assemble and clamp the joint.
F. For stock thicker than 25 mm (1"), you may wish to use double biscuits at each location. Set the height
adjustment to allow at least 4.76 mm (3/16") of stock between the biscuit and the edge of the work surface.
Make all cuts at this fence setting before readjusting the fence for the lower cuts. Again, there should be at least
5 mm (3/16") of stock between the biscuit and the outside wall and between the biscuits themselves (Figure 18).
2. FRAME JOINTS (Figure 19)
Frame joints are an ideal application for biscuit joinery. With the plate joiner you can create a very strong, precise
joint that is much faster to make than a dowel or mortise and tenon joint. Figure 19 shows two types of frame
joints. Follow the steps outlined below.
A. Arrange the workpieces on a flat work surface exactly as they are to be assembled.

OPERATION
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source
before making any adjustments or removing/installing attachments or accessories.
Plate joiners are primarily used for making cabinetry and furniture, joining millwork or other similar applications where
a strong, accurate joint is required in wood or wood by-products. There are literally hundreds of variations of joints that
can be made with your Plate Joiner. We will limit our discussion to six basic joints that can be used to build on and
adapt to your own applications. The following are some basic set-up steps that will apply to all biscuit joints.
1. BISCUIT SIZE SELECTION
As mentioned earlier, the three biscuit sizes are #0, #10 and #20. It is a good rule of thumb to use the largest
biscuit size that will physically fit in the application. Unless you are joining narrow face or picture frames or using
12 mm (1/2") or thinner stock, you will find the #20 biscuit size to suit most applications. After selecting the
biscuit size, set the depth adjustment knob to the corresponding size (see Controls section). Also, be sure the fine
depth adjustment is correctly set by first testing in a scrap piece. This is extremely important as you do not want to
discover during glue-up that your biscuit slots are not quite deep enough.
2. BISCUIT LOCATION AND LAYOUT
Generally, biscuits may be spaced and located at your discretion. For edge joints, a good rule of thumb is to space
biscuits every 150 mm – 250 mm (6–10") on center. It is further recommended that biscuits be placed so that the
centerline of the end biscuits is 50 mm – 75 mm (2-3") from the end of the workpiece. When joining face frames
or picture frames where the workpiece is narrow, you may have to choose the smaller biscuit sizes to keep from
“breaking out" on the end of the joint. Breaking out should be avoided if possible, but if not you can assemble the
joint and trim off the exposed biscuit tip after the glue sets (Figure 13). When working with material up to 25 mm
(1") thick, we advise to use a single biscuit located in the approximate center of the material thickness. If thicker
stock is to be joined, you may choose to use 2 biscuits across the thickness for greater strength (Figure 14).
Biscuit locations should be marked by first positioning the mating pieces exactly as they are to be assembled.
Next, make a mark at 90° to the joint interface across both pieces at the desired biscuit locations (Figure 15). See
Application section for more specific information on joint layout. The marks you make will then be aligned
with one of the center registration marks on the tool, again, depending upon your specific application.
3. MAKING THE CUT
Prior to making any cut, be sure that all fence adjustments are set and lock knobs are tight. Also, be sure you have
selected the proper depth setting. Clamp your workpiece firmly and align the plate joiner’s center registration mark
with your layout mark. Turn on the tool and let the blade come up to full speed (approximately 1 second). Grasping
the switch handle and auxiliary handle and positioning the fence firmly and squarely against the workpiece, plunge
the blade until it bottoms against the stop. Continuing to hold the tool squarely and firmly, allow the return spring to
retract the blade from the work and then release the switch to shut the tool off. It will take some practice to obtain a
“feel” for the tool to produce accurate joints, so practicing in scrap wood first is advisable.
4. JOINT ASSEMBLY
After your joints are cut, you may wish to trial fit everything together before gluing. When you are satisfied with your
joints, evenly spread any good quality woodworking glue in each slot as well as on the mating flat surfaces of your
joint. Place biscuits in the slots, assemble the joint and clamp until dry. For a biscuit joint to be most effective, it is
important that the biscuits themselves be in contact with the glue. This is because the biscuits absorb the moisture
in the glue and expand to form a tight joint.

ADJUSTABLE
FENCE
45
The heart of your plate joiner is the base/fence assembly. All of the controls that let you make a variety of precision cuts
are located on this assembly. Take a few minutes to become familiar with the various controls. ALWAYS TURN OFF AND
UNPLUG PLATE JOINER BEFORE MAKING ANY ADJUSTMENTS.
1. ADJUSTABLE FENCE
The adjustable fence provides a sturdy, precise reference surface to determine the point at which the slots for the
biscuits will be cut. Its adjustable height feature allows you to position biscuit slots as close as 5 mm (3/16") and
as distant as 35 mm (1-3/8") measured from the workpiece surface to the centerline of the blade (Figure 6). The
adjustable angle feature allows a full range of settings from 0° to 90 as well as a reverse 45° bevel which allows
outside registration on miter joints. (See Applications section under Miter Joints, Figure 26.)
The height adjustment is accomplished by first loosening the lock knob on the right side of the fence and then
rotating the knurled adjustment knob until the desired height is reached (Figure 5).
Tightening the lock knob will then automatically align the fence parallel to the blade and lock it in position. The
vertical scale and pointer located directly under the lock knob can be used to assist in setting this height. The scale
readings indicate distance from the blade centerline to the fence surface when the fence is set at 90° (see
Figure 6). The fence angle can be set simply by loosening the lock knob on the left side of the tool, aligning the
protractor scale with the pointer and tightening the lock knob.
2. PLUNGE DEPTH ADJUSTMENT
The depth of cut can be set to match the dimensions of the particular size biscuit you will be using. The numbers
on the depth adjustment knob (0, 10, 20, M) coincide with the three sizes of biscuits shown in Figure 2. The letter
M stands for the maximum depth capacity of the tool which is 20 mm (25/32"). This depth is obtainable only with
a new blade and by backing out the fine adjustment screw (see next section).
NOTE: The M setting has been provided for future use and will not be necessary for most biscuiting operations. To
select a depth, align the appropriate number with the red mark scribed in the tool’s housing, as shown in Figure 7.
Rotate the depth adjustment knob to the desired position and it will “click” into place.
3. FINE DEPTH ADJUSTMENT
You may encounter situations where you want to leave a little looseness in your joint so that you can move it
slightly before the glue sets up. For these instances a fine depth adjustment has been provided. To adjust, you
must first raise the adjustable fence to its uppermost position. Then insert the T20 torx wrench provided into the
opening as shown in Figure 8. Turn the depth adjustment screw clockwise for less depth and counterclockwise for
increased depth. Each full turn causes a change in depth of 1 mm (0.04"). Always check the depth adjustment by
first making test cuts in scrap wood.
4. ANTI-SLIPPAGE PINS
Plate Joiners tend to slide to the right with respect to the workpiece when making a cut. This tendency is increased
with a dull blade or when plunging very rapidly. Anti-slippage pins have been provided to reduce this tendency
and are located on the front registration surface on either side of the blade opening slot. When making some
joints, you may wish to retract the anti-slippage pins so as not to scratch your workpiece in a visible area. For this
purpose, simply rotate the anti-slippage pins approximately 1/6 of a turn and they will retract back behind the front
registration surface. A flat blade screwdriver can be used to rotate the pins as shown in Figure 9.
5. BOTTOM REGISTRATION SURFACE
For certain applications, you will want to use the bottom surface of the plate joiner for alignment. When using the
bottom registration surface, the adjustable fence should be set to 0° and the height setting is unimportant. This
surface is used primarily when making ‘T’ joints (see applications section). The distance between the centerline of
the blade and the bottom registration surface is fixed at 9.5 mm (3/8") which allows centering on 19mm (3/4") thick
stock. The 3 red marks on the bottom registration surface indicate the centerline (or the deepest point) of the biscuit
cut and the approximate width of a #20 biscuit so that you’ll know where the edge of the blade is and can prevent
breakthrough. To avoid breaking through the workpiece, align the shoe so that neither outside mark extends beyond
the end of the workpiece. If either side does, there is a good chance that the blade will break through the surface
and ruin your work.
6. DUST EXTRACTION
There are three options provided for collecting dust from your plate joiner as described below.
A. Adjustable Direction Elbow (Figure 10)
This attachment inserts into the dust exhaust port on the right side at the rear of the base assembly and clicks
into place. To remove, pull out firmly. The directional elbow rotates easily to aim the dust in the most convenient
direction suitable for the particular application.
B. Dust Adaptor (Figure 11)
This attachment, when inserted as described above, allows the use of several common sizes of vacuum hose to
be attached for direct vacuum pick-up of the dust.
C. Dust Bag (Figure 12)
The dust bag provided fits snugly over the dust adaptor described above. To empty the bag, open the zipper
underneath and dump dust out.
NOTE: When the bag becomes full, the dust will back-up into the adaptor and the exhaust port on the right rear of
the tool. To clean out, turn off and unplug the tool and remove packed dust. The bag will hold the dust generated
from approximately 70 to 100 #20 biscuit cuts before filling up.

3. CORNER JOINTS (Figure 21)
Corner joints are another common and excellent application for biscuit joinery. Follow the procedure below.
A. Arrange the workpieces exactly as they are to be joined.
B. Select the biscuit size and layout the biscuit locations.
C. Set up the tool by selecting the proper depth setting, adjusting the fence to center on the stock thickness and
setting the angle to 90°.
D. For this joint, you will make cuts into the edge of one workpiece and the face of another. The edge cut is
performed the same as for edge to edge joints. The face cut is made by clamping the workpiece and
aligning the tool as shown in Figure 22. Turn the tool on, make the plunge cut and repeat for each
layout mark.
E. Glue, assemble and clamp the joint.
4. OFFSET JOINTS (Figure 23)
You may wish to have a deliberate offset between two workpieces. This is easily accomplished with your plate
joiner by performing the following steps.
A. Arrange the workpieces as they are to be assembled and layout the biscuit locations.
B. Set up the tool by selecting the proper biscuit size and adjusting the fence angle to 90°. Select the workpiece that
will be set back and adjust the fence height to center the cut within the thickness of that piece.
C. Clamp the workpiece, align the tool and make the plunge cut.
D. Next, adjust the fence up by an amount equal to the desired offset. Use the scale and pointer located on the right
side of the tool under the fence lock knob.
E. Clamp the second workpiece, align the tool and make the plunge cut.
F. Glue, assemble and clamp the joint.
5. EDGE MITER JOINTS (Figure 24)
Edge miters are most commonly used in box structures or for making multisided pedestals where you would like to
hide the end grain. Once again, biscuit joinery is an outstanding method to use both for added strength as well as
ease of assembly. Follow the steps below to assemble a 90° joint.
A. Position the workpieces as they are to be assembled and layout biscuit locations on the outside of the joint.
B. Set up tool by first setting fence angle to 90°. Make the fence adjustment such that the biscuit is located toward
the inside of the joint where the material is thicker, then select the biscuit size so that the blade does not protrude
through the outside wall when the cut is made (Figure 25).
C. Clamp the workpiece and align the tool as shown in column in Figure 26.
D. Turn on the tool and make the plunge cut.
E. Glue, assemble and clamp the joint.
F. For joints other than 90° see outside registration column Figure 27 for proper fence angle setting.
The above method will produce a joint where the outside surfaces of the joint are aligned. If you wish to produce a joint
where the inside surfaces are aligned, use the following procedures for a 90° joint.
A. Position workpieces as they are to be assembled.
B. Layout biscuit locations on the inside of the angle.
C. Set up tool by setting fence angle to 45°. Set vertical fence adjustment so that the biscuit is located toward the
inside of the joint where material is thicker. Select biscuit size so that the blade does not protrude through the
outside face of the material.
D. Clamp the workpiece and align the tool as shown in Figure 28.
E. Make the plunge cut and repeat for all biscuit locations.
F. Glue, assemble and clamp the joint.
G. For joints other than 90° see inside registration column in Figure 27 for proper fence angle setting.
6. T-JOINTS (Figure 29)
Biscuit joining is a viable alternative to dadoing when making a T-joint. T-joints are most commonly used when
attaching shelves to the sides of a case. The method described below will work if your shelf material is at least
5/8" thick.
A. Place the workpieces on a work surface exactly as you will be assembling them in the form of an upside down
“T.” Mark lightly along the joint where the top of the shelf is to end up (Figure 30). Mark biscuit locations at the
joint interface on the shelf piece only.
B. Lay the shelf down on the mating workpiece. Clamp the two workpieces together and to the work surface in this
position (Figure 31).
FIG 32
LAYOUT LINE
FIG 33
R
B. Select the proper biscuit size based on the length of the joint. (If the frame pieces are too narrow for a #0 biscuit,
you will have to allow the biscuit tip to protrude slightly and then trim it off after the joint is dry (Figure 13).
C. Lay out the biscuit locations.
D. Set up the tool by selecting the depth that corresponds to the chosen biscuit size. Lock the fence at 90° and
adjust the fence height to center the biscuit on the stock thickness.
E. Clamp the workpiece and position the Plate Joiner to make the first cut (Figure 20).
F. Turn on the tool and make the plunge cut.
G. Repeat for each layout mark.
H. Glue, assemble and clamp the frame.
FIG 31
C. Set up the tool by selecting the proper biscuit size and setting the adjustable fence angle at 0°.
D. Using the bottom registration surface, align the tool with the biscuit location marks and make a vertical and a
horizontal plunge cut for each biscuit location as shown in Figure 32.
E. Glue, assemble and clamp the joint.
