DEPTH OF CUT
The biscuit joiner can be adjusted to three standard cutting
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 as-
sembly. 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 adjustment 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.
n
Unplug the biscuit joiner.
n 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
in figure 5.
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 adjustment
knob.
n 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.
n
Unplug the biscuit joiner.
n 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.
n Rotate the jam nut to the right for a more shallow cut, or
to the left for a deeper cut.
n 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.
n 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.
