Infeed Table Adjustments
After a full table realignment, the infeed table
height should be re-zeroed, and a few
components of the infeed table will need to be
adjusted.
1. Disconnect the jointer from the power
source!!
2. To re-zero the infeed table height, raise the
infeed table so it is approximately at the
same height as the cutting arc of the
cutterhead.
3. Place a straight edge over the infeed table so
it hangs over the cutterhead.
4. Fine-tune the table height to set the depth
of cut to zero. When properly set, cutters
should be barely scraping the straight edge
when the cutterhead rotates.
5. With the infeed table height zeroed, follow
the steps in “ DRO Calibration ” to re -zero the
digital readout.
6. Check if the infeed table height scale is still
pointing at zero. If not, loosen the 2 hex
screws and readjust the pointer.
Infeed Table Positive Stops Adjustments
Under the infeed table, there are three positive
stops:
Minimum Depth Stop - When properly adjusted,
it should stop the infeed table when the depth
of cut is between 0” - 1/32”.
Maximum Depth Stop - Prevents the infeed
table from lowering too much and getting more
than 3/4” depth of cut.
Depth Stop for Jointing – Limits the depth of cut
to 1/8” for jointing operations. This positive stop
is located behind the depth stop knob, which is
accessible when the panel is removed.
To test this depth stop, make sure the bracket as
shown in the picture above aligns with the stop
bolt, then lower the infeed table. If this positive
stop is set correctly, it will stop the table at 1/8”.
To Make Adjustments:
1. Disconnect the jointer from the power
source!!
2. Loosen the jam nut that locks the stop bolt.
3. Rotate the stop bolt until it stops the infeed
table at the correct height.
4.
Re-tighten the jam nuts.
