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 9. Turn the depth adjustment screw
clockwise for less depth and counterclockwise for increased depth.
Each full turn causes a change in depth of 1mm (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 10.
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
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.
