Surface Planing
The purpose of surface planing on the jointer is to make one flat face on the workpiece (see Figures 32 & 33) to prepare it for surface planing on a thickness planer.
NOTICE
If you are not experienced with a jointer, set the depth of cut to zero and practice feeding the workpiece across the tables as described. This procedure will better pre- pare you for the actual operation.

To surface plane on the jointer:
1.Read and understand SECTION 1: SAFETY.
2.Make sure you inspect your workpiece for dangerous conditions as described in the Stock Inspection & Requirements.
3.Set the cutting depth for your operation. (We suggest 1⁄32" for surface planing.)
4.Make sure your fence is set to 90˚.
5.If your workpiece is cupped (warped), place the concave side (Figure 33) face down on the surface of the infeed table.
6.Start the jointer.
Failure to use push blocks when surface planing may result in cutterhead contact with your hands, 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 each hand, press the workpiece down on the infeed table and against the fence with firm pressure, then feed the workpiece over the cutterhead, as shown in Figure 32.
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 resting 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. DO NOT place either hand closer than 4" from the cutterhead! Failure to heed this warning could result in serious personal injury.
8.Repeat Step 7 until the entire surface is flat.
