• Make sure any stock you joint is properly dried. Wood with a moisture content over 20% will cause unnecessary wear on the knives and will produce undesirable results. NOTICE Occasionally, you will find woods that defy all rules. In those rare cases, it is best to feed the workpiece slowly and take several shallow cuts. A few extra passes will hurt much less than a ruined workpiece. Squaring Stock The jointer performs two of the four required operations for squaring up stock—surface planing and edge jointing. To help you understand these two operations better, we quickly describe the squaring process below: Step 1. Surface plane the concave face with a JOINTER to make it flat. Step 2. Edge joint the best edge with a JOINTER to make it flat. Step 3. Plane the second face with a THICKNESS PLANER to make it parallel to the first face. 15 30 45 Step 4. Rip the second edge with a TABLE SAW to make it parallel to the first edge. G0500/G1018/G1018HW 8" Jointers -29 Surface Planing The purpose of surface planing is to make a flat face on a piece of stock to prepare it for planing on a thickness planer. See Figure 44. Figure 44. Illustration of surface planing effects. 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. Make sure that you have read and understand all safety instructions in Section 1: Safety and that your stock has been inspected for safe operation as described in the “Stock Inspection” instructions earlier in this section. 2. Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.) 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 block in each hand, press the workpiece against the table and fence with firm pressure. 8. Feed the workpiece over the cutterhead as shown in Figure 45. Note—When your leading hand (with push block) gets within 4" of the cutterhead, lift it up and over the cutter- head, and place the push block 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 cutter- head when it is moving! 9. Repeat steps 7-8 until the entire surface is flat. Figure 45.

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.

Make sure your workpiece is within the minimum and maximum stock dimensions that your Grizzly 8" Jointer can safely process. (Check the data sheet in the back of this manual for your particular model.) 3. Set the cutting depth for your operation. (We suggest between 1.16" and 1.8" for edge jointing, using a more shallow depth for harder wood species or for wider stock.) ...
