ADJUSTMENTS
WARNING:
If any parts are missing, do not operate tool until the
missing parts are replaced. Failure to do so could result
in possible serious personal injury.
DEPTH OF CUT ADJUSTMENTS
Your biscuit joiner can be adjusted to three standard
cutting depths to accommodate three standard size biscuits
— #R1, #R2, and #R3. Adjustments are made by engaging
slots on depth adjustment knob with tabs on rear base. For
example, when using a #R1 size biscuit, rotate the depth
adjustment knob until the slot marked 1 aligns with the
depth indicator mark on the rear base. When using a #R2
size biscuit, rotate the depth adjustment knob until the slot
marked 2 aligns with the depth indicator mark on the rear
base, and when using a #R3 size biscuit rotate the depth
adjustment knob until the slot marked 3 aligns with the
depth indicator mark on the rear base.
See Figure 3.
TO SET DEPTH ADJUSTMENT KNOB
■ Unplug your detail biscuit joiner.
WARNING:
Failure to unplug biscuit joiner could result in accidental
starting causing possible serious personal injury.
■ Pull knurled adjustment knob and jam nut in the direction
of the arrow shown in figure 3.
NOTE: Knob and jam nut are spring loaded, therefore
pulling them in the direction of the arrow shown puts
pressure on the spring and releases pressure from the
depth adjustment knob.
■ Rotate depth adjustment knob until desired slot setting
aligns with tabs on rear base — 1, 2, or 3.
■ Next release knurled adjustment knob and jam nut applying
pressure from spring on depth adjustment knob.
Make a test cut in a scrap piece of wood. Fit the correct size
biscuit into biscuit slot. If biscuit slot is too deep or too
shallow, fine adjustments to the depth setting can be made
by loosening knurled adjustment knob and making fine
adjustments with the jam nut. Turning jam nut forward will cut
shallow biscuit slots. Turning jam nut backwards will cut
deeper biscuit slots. 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.
TO MAKE FINE ADJUSTMENTS
See Figure 4.
■ Unplug your detail biscuit joiner.
■ Loosen knurled adjustment knob. This knob is used as a
lock nut only. Loosen by twisting it in the opposite direc-
tion away from jam nut.
■ Turn jam nut forward for a more shallow cut, or
backwards for a deeper cut.
■ Once desired depth of cut is reached, hold jam nut so that
it will not move out of adjustment. Next, tighten knurled
adjustment knob against jam nut.
■ Recheck depth setting by making a test cut in a scrap
piece of wood. Also periodically check depth setting for
accuracy.
