DEPTH OF CUT ADJUSTMENTS
Your plate 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
depth adjustment knob with tabs on 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 adjustment knob to the slot marked
10, and when using a #20 size biscuit rotate the depth
adjustment knob to the slot marked 20.
See Figure 3.
TO SET DEPTH ADJUSTMENT KNOB
1. Unplug your plate joiner.
2. 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.
3. Rotate depth adjustment knob until desired slot setting
aligns with tabs on rear base assembly — 0, 10, or 20.
4. 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.
1. Unplug your plate joiner.
2. Loosen knurled adjustment knob. This knob is used as
a lock nut only. Loosen by twisting it in the opposite
direction away from jam nut.
WARNING:
Failure to unplug your plate joiner could result in
accidental starting causing possible serious personal
injury.
3. Turn jam nut forward for a more shallow cut, or
backwards for a deeper cut.
4. 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.
5. Recheck depth setting by making a test cut in a scrap
piece of wood. Also periodically check depth setting for
accuracy.
See Figure 4.
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.
