OPERATION
 Unplug the biscuit joiner.
 Loosen the knurled adjustment knob. This knob is used
as a lock nut only. Loosen by twisting it in the opposite
direction away from the jam nut.
 Rotate the jam nut to the right for a more shallow cut, or
to the left for a deeper cut.
 Once desired depth of cut is reached, hold the jam nut
so that it will not move out of adjustment. Next, tighten
the knurled adjustment knob against jam nut.
 Recheck the depth setting by making a test cut in a scrap
piece of wood. Also periodically check the depth setting
for accuracy. Rotating the jam nut to the right will cut
shallow biscuit slots. Rotating the jam nut to the left will
cut deeper biscuit slots.
FENCE HEIGHT
The adjustable fence on the biscuit joiner can be moved
up or down to adjust the position of the blade in relation to
the top of the workpiece. A scale on each side of the fence
indicates the height of the fence from the center of the blade.
The fence can be positioned up to two inches from the center
of the blade. However, the scale and indicator point can only
be set up to 2 in. from the center of the blade. Scale marks
are in increments of 1/16 in.
SETTING THE FENCE HEIGHT
See Figure 7, page 18.

Unplug the biscuit joiner.
 Loosen the locking knob approximately one turn.
 Move the fence up or down by rotating the height adjust-
ment knob until the indicator point is aligned with the
desired dimension on the scale.
 Tighten the locking knob securely.
FENCE ANGLE
The adjustable fence on the biscuit joiner can be set at angles
ranging from 0° to 135°, with accurate positive stops set in 45°
increments. A scale is located on each side of the adjustable
fence for identifying these positive stop angles. Each stop
reached when rotating the adjustable fence from one angle
setting to another equals a 45° positive stop angle change.
SETTING THE FENCE ANGLE
See Figure 8, page 18.

Unplug the biscuit joiner.
 Loosen the locking knob approximately one turn.
 Rotate the fence to the desired angle.
 Tighten the locking knob securely.
MAKING EDGE-TO-EDGE JOINTS
See Figures 9 - 10, page 18.
Edge-to-edge joinery is one of the most basic and easily-
constructed joints.

Unplug the biscuit joiner.
 Prepare the workpieces by laying them side by side on a
workbench in the order in which they will be assembled.
 Using a square, determine the location of each biscuit
spline joint and mark the center of each joint by drawing
a line across each workpiece.
NOTE: Mark the edges 2 in. from the ends of the work-
pieces. The joint will be stronger if you use multiple
biscuits placed close together.
 Loosen the locking knob approximately one turn and set
the fence angle at 90°.
 Set the fence height at the desired dimension on the scale
by rotating the height adjustment knob.
NOTE: The scale indicates the height of the fence from
the center of the blade.
 Tighten the locking knob securely.
 Select the correct depth of cut setting to match the biscuit
size you are planning to use. Make a test cut in a scrap
piece of wood from the same workpiece if possible.
 Clamp the workpiece securely so that it will not move
during the cut.
 Plug the biscuit joiner into the power supply and prepare
to make the first cut. Grasp and hold the biscuit joiner
securely with both hands.
 Place the fence against the board and align the indica-
tor marks on the fence with the centerline mark(s) on the
board.
 Depress the switch trigger to turn on the biscuit joiner.
Allow the blade to reach full speed, 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 all desired biscuit slots.
 Once all biscuit slots have been cut, place a biscuit in
each joint and dry-assemble the workpiece. 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 workpieces together until the glue sets up.
