MAKING EDGE MITER JOINTS
See Figures 19 - 21.
n
Unplug the biscuit joiner.
n Place the pieces of wood to be joined on a level work-
bench.
n Mark the centerline of the joint on each board.
n When making edge miter joints with workpieces that
have different thicknesses, clamp the pieces securely to
a workbench with the long sides up. This will assure that
the outside surfaces will match.
n Loosen the locking knob and set the fence angle at
135°.
n Set the fence height at the desired dimension on the scale
by rotating the height adjustment knob.
n Tighten the locking knob securely.
n Place the biscuit joiner on the workpiece with the adjust-
able fence resting on the long side of workpiece. The base
or vertical fence should be against the mitered edge of
the workpiece.
n Recheck the fence height setting to make sure it will not
cut through the workpiece.
n Align the indicator mark on the fence with the centerline
on the workpiece. Make sure the base or vertical fence is
pressed flat against the mitered edge of the workpiece.
n Plug the biscuit joiner into the power supply and prepare
to cut the slot.
n Depress the switch trigger to turn on the biscuit joiner,
then push it forward to extend the blade into the wood.
n When the base assembly bottoms out against the depth
of cut adjustment knob setting, pull back, releasing pres-
sure on the spring. The blade will retract from the biscuit
slot.
n Repeat this procedure for cutting the mating slot and all
required miter joint slots.
n Once all slots have been cut, place a biscuit in each joint
and dry-assemble the workpieces. Make sure each joint
lines up and fits.
n Finally, disassemble workpieces and place a bead of glue
in each slot. Also, spread a bead of glue over the entire
surface of the joint. Reinsert the biscuits and assemble
workpieces.
n Clamp workpieces together until the glue sets up.
If the workpieces are of the same thickness, clamp them
securely to a workbench with the short sides up. Set
the fence angle at 45°. Place the biscuit joiner on the
workpiece with the adjustable fence resting on the short
side of the workpiece and the base or vertical fence
against the mitered edge of the workpiece. Follow steps
above to cut required slots.

NOTE: Before cutting slots, make sure the blade will not
cut through the workpiece and that both the vertical and
horizontal fences are pressed flat against the mitered
edge and face of the workpiece.
