G0609 12" Parallelogram Jointer
The purpose of edge jointing is to produce a fin-
ished, flat-edged surface (see Figures 24 & 25
)
that is suitable for joinery or finishing. It is also a
necessary step when squaring rough or warped
stock.
Figure 25. Illustration of edge jointing results.
To edge joint on the jointer:
1. Read and understand SECTION 1: SAFETY,
beginning on
Page 7.
2. Inspect your stock for the dangerous condi-
tions described in Stock Inspection instruc
-
tions, beginning on
Page 21.
3. Set the cutting depth for your operation.
Note: We suggest between
1
⁄16" and
1
⁄8" for
edge jointing, using a more shallow depth for
hard wood species or for wide stock.
4. Set the fence to 90˚ and place the workpiece
on the jointer.
5. If your workpiece is cupped (warped), place
it so the cupped edge is face down (
Figure
25) on the surface of the infeed table.
6. Start the jointer.
NOTICE
If you are not experienced with a jointer,
set the depth of cut to 0", and practice
feeding the workpiece across the tables as
described below. This procedure will better
prepare you for the actual operation.

The step below requires you to use a push
block. Failure to use push blocks when
surface planing may result in cutterhead
contact, which will cause serious personal
injury. Always use push blocks to protect
your hands when surface planing on the
jointer.
7. With a push block in your leading hand,
press the workpiece against the table and
fence with firm pressure. Use your trailing
hand to guide the workpiece through the cut,
and feed the workpiece over the cutterhead
(See Figure 24).
Note: If your leading hand gets within 4"
of the cutterhead, lift it up and over the
cutterhead, and place it on the portion of the
workpiece that is over the outfeed table. Now,
focus your pressure on the outfeed end of
the workpiece while feeding, and repeat the
same action with your trailing hand when it
gets within 4" of the cutterhead. To keep your
hands safe, DO NOT let them get closer than
4" from the cutterhead when it is moving!
8. Repeat Step 7 until the entire edge is flat.
