Factory adjustments that should be verified: 1. Outfeed Table Height (page 31) 2. Depth-of-Cut Scale (page 32) 3. Fence Stops (page 32) G0526 6" Jointer -21 SECTION 6: OPERATIONS General Your safety is important! Please follow the warnings below during this entire section: Damage to your eyes, lungs, and ears could result from failure to wear safety glasses, a dust mask, and hearing protec- tion while using this machine. Loose hair and clothing could get caught in machinery and cause serious personal injury. Keep loose clothing rolled up and long hair tied up and away from machinery. Figure 21. Correct and incorrect grain alignment to cutterhead. Stock Inspection & Requirements Here are some rules to follow when choosing and jointing stock: • DO NOT joint or surface plane stock that contains knots. Injury to the operator or damage to the workpiece can occur if the knots become dislodged during the cutting operation. • DO NOT joint or surface plane “against” the grain direction. Cutting “against” the grain increases the likelihood of stock kickback (See Warning #13 on page 5), as well as tear-out on the workpiece. • Jointing and surface planing “with” the grain produces a better finish and is safer for the operator. Cutting “with” the grain is described as feeding the stock on the jointer so the grain points down and toward you as viewed on the edge of the stock (Figure 21). Note—If the grain changes direction along the edge of the board, your best bet for improving cut quality is to decrease the cutting depth and make additional passes. -22- G0526 6" Jointer • Remove foreign objects from the stock. Make sure that any stock you process with the jointer is clean and free of any dirt, nails, staples, tiny rocks or any other foreign objects that may damage the jointer blades. • Only process natural wood fiber through your jointer. Never joint MDF, particle board, plywood, laminates or other synthetically made materials. • Make sure all stock is sufficiently dried before jointing. Wood with a moisture content over 20% will cause unnecessary wear on the knives and will produce undesirable results. • Make sure the stock meets the minimum dimension requirement (Figures 22 and 23) before edge jointing or surface planing. 10" Min. 1" Min. 1.2" Min.

Squaring Stock Squaring stock involves four steps that should be performed in the order below. The following pages will go into more detail. 1. Surface Plane On The Jointer—The concave face of the workpiece is surface planed flat with the jointer. End Grain 2. Surface Plane On A Thickness Planer—The opposite face of the workpiece is surface planed flat with a thickness planer. Previously Surface Planed Face End Grain 3. Edge Joint On The Jointer—The concave edge (viewed from end-to-end) of the workpiece is edge jointed flat with the jointer. Face Grain 4. Rip Cut On A Table Saw—Place the jointed edge of the workpiece against a table saw fence and rip the opposite edge off. 15 30 45 Previously Jointed Edge End Grain G0526 6" Jointer -23 Surface Planing The purpose of surface planing on the jointer is to make one flat face on a piece of stock (Figure 24) to prepare it for surface planing on a thickness planer. Figure 24. Illustration of surface planing results. 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. To surface plane on the jointer: 1. Read and understand Section 1: Safety, beginning on page 3. 2. Make sure your stock has been inspected for dangerous conditions as described in the “Stock Inspection” instructions, beginning on page 22. 3. Set the cutting depth for your operation. (We suggest 1.32" for surface planing, using a more shallow depth for harder wood species or for wider stock.) 4. Make sure your fence is set to 90° 5. If your workpiece is cupped (warped), place it so the concave side is face down on the surface of the infeed table. 6. Start the jointer. 7. With a push paddle in each hand, press the workpiece against the table and fence with firm pressure. Failure to use push paddles when surface planing could result in the operator’s hands coming into contact with the cutterhead, causing serious personal injury. Always use push paddles when surface planing on the jointer. 8. Feed the workpiece over the cutterhead. Note—When your leading hand (with push paddle) gets within 4" of the cutterhead, lift it up and over the cutterhead, and place the push paddle on the portion of the workpiece that is over the outfeed table. At this point, 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 cutterh...
