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.
