Multiple Board Hazard Only plane one board at a time (Figure 33). Whether you use guide rails or not, never attempt to plane more than one board at a time side-by-side. If one board is slightly lower that the other, the feed roller will only hold the highest board, while the lower board will be free to slip when the knife contacts it. This hazardous situation can result in one board being ejected from the machine, causing serious injury. Sacrificial Table Use If using a sacrificial table, you must clamp it to the cast iron table (Figure 34) to prevent workpiece ejection. Never stack two boards on top of one another and feed them both into the planer/moulder to compensate for a workpiece that may be too thin. Planing with two loose stacked boards can result in workpiece ejection, causing injury. Figure 33. Only plane one board at a time. Figure 34. Sacrificial table mounting. -24- W1812 Owner's Manual (Mfg. since 3/09) shop fox: Planing Operation The maximum cutting depth for soft wood at full cutterhead width is no more than 1/8" deep. The harder the wood, the shallower the cutting depth and the slower the feed rate should be. A series of light passes typically results in a smoother finish with less snipe. The basic steps of operating the machine as a planer are as follows: 1. DISCONNECT THE PLANER/MOULDER FROM POWER! 2. Review the Workpiece Inspection list on Page 23 and the AVOIDING KICKBACK warning on this page. 3. Review Planing Do's and Don'ts on Page 24, and take the appropriate safety measures. 4. If you have not already done so, adjust the feed rollers and spring tension as outlined in the Feed Roller Height and Spring Tension section on Page 21. 5. Measure the workpiece thickness, loosen the head-stock lock lever, and use the handwheel (Figure 35) to adjust the headstock for a light pass. 6. Wearing gloves, manually rotate the cutterhead to make sure that the knives do not contact the table or guide rails if used. 7. PUT ON SAFETY GLASSES, EAR PROTECTION, AND A RESPIRATOR. 8. Tighten the headstock lock lever, start the machine, and turn the feed speed control dial to a medium speed. 9. Stand clear of the workpiece path, place the flat side of the board down on the table, and slowly feed the workpiece into the machine until the feed roller begins to pull the workpiece. 10. For subsequent passes, adjust the headstock height and feed rate as necessary until the desired thickness and finish is achieved. Note: To reduce snipe, feed multiple pieces of stock butted up end-to-end, or experiment with a lighter feed roller spring tension. You can also try to raise one or both feed rollers up slightly. awarning AVOIDING KICKBACK! • Always stand to one side of the machine. • DO NOT plane more than one piece at a time. • Always plane WITH the grain direction of the wood. Never plain cross-grain or end-grain. • DO NOT remove more than V8M of material on each pass. • Support the workpiece on both ends. Get assistance if you are planing long lumber, or use roller stands to support the workpiece. • Carefully inspect all stock to make sure it is free of large knots or foreign objects that may damage your blades.

However, you still must pay special attention to workpiece support and knife-to-table clearance. Refer to the following examples to avoid common workpiece setup mistakes. ACAUTION REMEMBER, moulding knives have many different profiles, before starting the machine, always verify that the moulding knives do not contact any part of the workpiece guide rails, feed roller swing arm, or the table surface. Failure to verify knife clearance may result in severe injury and machine damage! Edge Forming Knife Clearance A wooden sacrificial table clamped to the cast iron table and a three-piece guide system (Figure 36) will prevent tool and table damage by absorbing the full sweep of the knife. Never attempt to use edge forming profile knives without pre-installing a wooden sacrificial table. Often these types of knives sweep lower than the workpie...
