centerline of the blade (see Figure I). 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 BB.)
b. The height adjustment is accomplished by first
loosening the lock knob
fence and then rotating the knurled adjustment
knob
until the desired height is reached (see

Figure H).
c. The rack and pinion system of the fence automatically
aligns the fence parallel to the blade, with the lock
knob locking 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 I). 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.
Plunge Depth Adjustment (Fig. E, J)
The depth of cut can be set to match the dimensions of the
particular size biscuit you will be using. The numbers on the

three sizes of biscuits shown in Figure E. The letter M stands
for the maximum depth capacity of the tool which is 25/32"
(20 mm). 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 arrow
scribed in the tool's gear box, as shown in Figure J. Rotate
the depth adjustment knob to the desired position and it will
"click" into place.
Fine Depth Adjustment (Fig. K)
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
6
to its uppermost position. Then insert
the T20 Torx wrench provided into the opening. Turn the
depth adjustment screw
counterclockwise for increased depth. Each full turn causes
a change in depth of 0.04" (1 mm). Always check the depth
adjustment by first making test cuts in scrap wood.
Anti‑Slippage Pins (Fig. K)
Biscuit joiners tend to slide to the left 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
7
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
16
on the right side of the

(0,10, 20, M) coincide with the

clockwise for less depth and
registration surface. A flat blade screwdriver can be used to
rotate the pins as shown in Figure K.
Bottom Registration Surface
For certain applications, you will want to use the bottom
surface of the biscuit 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 3/8" (9.5 mm)
which allows centering on 3/4" (19 mm) thick stock. The
three grooves 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 end or your workpiece and ruin
your work.
Dust Extraction (Fig. L–N)
There are three options provided for collecting dust from
your biscuit joiner as described below.
WARNING: Risk of dust inhalation. To reduce the risk of
personal injury, ALWAYS wear an approved dust mask.
Adjustable Direction Elbow Attachment (Fig. l)
The adjustable direction elbow attachement
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.
Dust Adaptor (see Figure M1)
This straight attachment
above, allows the use of several common sizes of vacuum
hose to be attached for direct vacuum pick‑up of the dust.

The dust extraction port allows you to connect the tool to an
external dust extractor, either using the AirLock™ system, or a
standard 35 mm dust extractor fitment.
WARNING: ALWAYS use a vacuum extractor designed
in compliance with the applicable directives regarding
dust emission when sawing wood. Vacuum hoses of
most common vacuum cleaners will fit directly into the
dust extraction outlet.
Your tool is compatible with the D
connection system. The AirLock™ allows for a fast, secure
connection between the AirLock™ connector
