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 20ram (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. 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 counter-clockwise for
increased depth. Each full turn causes a
change in depth of lmm (0.04"). Always
check the depth adjustment by first making
test cuts in scrap wood.

Antkslippage pin
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°. The height setting is
unimportant. This surface is used primarily
when making 'T' joints (see applications
section). The distance between the
centreline of the blade and the bottom
registration surface is fixed at 3/8" (9.5ram)
which allows centreing on 3/4" (19mm)
thick stock. The 3 red marks on the bottom
registration surface indicate the centreline
(or the deepest point) of the biscuit cut and
