G0609 12" Parallelogram Jointer
-23-
The purpose of surface planing on the jointer is
to make one flat face on a piece of stock (see
Figures 22 & 23) to prepare it for surface planing
on a thickness planer.
To surface plane on the jointer:
1. Read and understand SECTION 1: SAFETY,
beginning on Page 7.
2. Inspect your stock for the dangerous con-
ditions described in Stock Inspection &
Requirements instructions, beginning on
Page 21.
3. Set the cutting depth for your operation.
Note: We suggest 1 ⁄
32
" for surface planing,
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.
— If your workpiece is cupped (warped),
place it so the cupped or concave side is
face own (
Figure 23) on the surface of the
infeed table.
5. 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. This procedure will better pre-
pare you for the actual operation.

6. With a push block in each hand, press the
workpiece against the table and fence with
firm pressure, and feed the workpiece over
the cutterhead (
Figure 22).
Note: If your leading hand (with push block)
gets within 4" of the cutterhead, lift it up and
over the cutterhead, and place the push
block on the portion of the workpiece that is
on the outfeed table. Now, focus your pres-
sure 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!
7. Repeat Step 6 until the entire surface is flat.

The step below requires you to use push
blocks. 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.
