CUTTING VERTICAL BOARDS
See Figures 16 - 17, page 19.

Unplug the biscuit joiner.
 Loosen the locking knob and set the fence angle at 0°.
 Set the fence height at the highest setting (2 in.) by rotat-
ing the height adjustment knob.
 Retighten the locking knob.
 Select the correct depth of cut setting for the biscuit size
you plan to use.
 Clamp the workpiece securely.
 Place the biscuit joiner on a vertical board and align the
indicator marks on the base assembly with the centerline
on the vertical board.
 Place a straight piece of wood on the vertical board and
securely clamp both boards flush against the base as-
sembly. This piece of wood is used for a fence or guide.
It must be square with the sides of the vertical board and
parallel with the centerline.
 Align the centerline on the bottom of the base assembly
with marked intersection for biscuit slot.
 Plug the biscuit joiner into the power supply, grasp and
hold the biscuit joiner securely with both hands, and
prepare to cut the slot.
 Depress the switch trigger to turn on the biscuit joiner,
then push it down to extend the blade into the wood.
 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.
 Repeat this procedure for cutting all required slots in
vertical boards.
 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.
 Finally, disassemble the 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 as-
semble the workpieces.
 Clamp the workpieces together until the glue sets up.
MITER JOINTS
See Figures 18 - 21, pages 19 - 20.
There are two types of miter joints that can be made using
biscuits: flat miters and edge miters. Flat miters are used
when making picture frames. Edge miters are used when
making boxes or things where you don’t want to show the
end grain of the wood.
OPERATION
MAKING FLAT MITER JOINTS
See Figure 18, page 19.

Unplug the biscuit joiner.
 Place the pieces of wood to be joined on a level work-
bench.
 Using a combination square, draw a line through the
center of each joint perpendicular to the mitered edges.
 Set the fence angle at 90°, set the fence height at the
desired dimension on the scale, select the correct depth
of cut setting for the biscuit size you plan to use, and
clamp the workpiece securely.
 Align the indicator mark on the fence with the centerline
on the workpiece.
 Plug the biscuit joiner into the power supply, grasp and
hold the biscuit joiner securely with both hands, and
prepare to cut the slot.
 Depress the switch trigger to turn on the biscuit joiner,
then push it forward to extend the blade into the wood.
 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.
 Repeat this procedure for cutting the mating slot and all
required miter joint slots.
 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.
 Finally, disassemble the 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 as-
semble the workpieces.
 Clamp the workpieces together until the glue sets up.
MAKING EDGE MITER JOINTS
See Figures 19 - 21, page 20.

Unplug the biscuit joiner.
 Place the pieces of wood to be joined on a level work-
bench.
 Mark the centerline of the joint on each board.
 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.
 Loosen the locking knob and set the fence angle at 135°.
 Set the fence height at the desired dimension on the scale
by rotating the height adjustment knob.
 Tighten the locking knob securely.
