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 screwdriver
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.

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
centerline
of the blade and the bottom
registration
surface
is fixed at 3/8" (9.5mm)
which allows centering
on 3/4" (19mm)
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.
