OPERATION
THE CONTROLS
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.
CAUTION: 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
3/16" (4.76mm) and as distant as 1-3/8"
(35mm) measured from the workpiece
surface to the centerline of the blade (see
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 mitre joints.
(See Applications section under Mitre
Joints, Figure 27.)
FIG 5
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 (see 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). If the depth scale
ever needs to be adjusted, loosen the two
screws that secure the scale and move
the scale until the pointer is indicating the
proper reading (see Figure 6).
