DEPTH OF CUT
The biscuit joiner can be adjusted to three standard cut-
ting depths to accommodate
three standard size biscuits
-- #0, #10, and #20. Adjustments
are made by engaging
slots on the depth adjustment knob with tabs on the rear
base assembly. For example, when using a #0 size biscuit,
rotate the depth adjustment knob to the slot marked 0.
When using a #10 size biscuit, rotate the depth adjust-
ment knob to the slot marked 10, and when using a #20
size biscuit rotate the depth adjustment knob to the slot
marked 20.
SETTING
DEPTH OF CUT
See Figure 5.
Unplug the biscuit joiner.
Select the correct depth of cut setting for the biscuit
size you plan to use. To select depth of cut, pull the
knurled adjustment knob and jam nut in the direction of
the arrow.
NOTE: The knob and jam nut are spring loaded. Pulling
them in the direction of the arrow puts pressure on the
spring and releases pressure from the depth adjust-
ment knob.
Rotate the depth adjustment knob until the desired slot
setting aligns with the tabs on the rear base assembly.

MAKING
FINE ADJUSTMENTS
See Figure 6.
Make a test cut in a scrap piece of wood. Fit the correct
size biscuit into the biscuit slot. The biscuit slot should
be deep enough to allow slightly more than one-half of
the biscuit into the slot. This extra room allows for proper
alignment of the wood being joined.
If the biscuit slot is too deep or too shallow, fine adjust-
ments to the depth setting can be made by loosening the
knurled adjustment knob and making fine adjustments
with the jam nut.
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.
