Note—If the table rollers are too high, snipe or chipping may occur at the ends of the workpiece. Only use the higher settings for rough cut lumber. If you are unsure about which height to use, experiment on scrap lumber by using the trial and error method. Always start at the smaller tolerances and work up. 3. Pull the adjustment lever up to the appropriate scale marks. Secure the adjustment lever by tightening the lock. Extreme Duty Planers -15 -16- Extreme Duty Planers Read the entire manual before making any cuts with your planer. Serious personal injury may result if safety or operational information is not understood or followed. Once assembly is complete and adjustments are done to your satisfaction, you are ready to start the machine. Turn on the power supply at the main panel. Press the START button. Make sure your finger is poised on the STOP button, just in case there is a problem. The planer should run smoothly with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further. Run the planer for a short time to ensure that the moving parts are working properly with no excessive vibration. If any problem develops, correct it before attempting to use the machine. If you cannot locate the source of unusual noises or cannot fix any problems that arise, immediately contact our Service Department at (570) 546- 9663 for help. Test Run SECTION 7: OPERATIONS Keep loose clothing out of the way of machin- ery and keep hair pulled back. Wear safety glasses dur- ing all operations on the planer. Failure to com- ply may result in serious personal injury. Disconnect power to the machine when perform- ing any adjustments or maintenance. Failure to do this may result in seri- ous personal injury. Always wear a dust mask when operating the plan- er.Usingthismachine produces sawdust which may cause allergic reac- tions or respiratory prob- lems. NOTICE If you are not familiar with how to properly use a planer. WE STRONGLY RECOMMEND that you read books, trade magazines, or get formal training. Operational Tips • Inspect lumber for defects, warping, cupping, twisting, and foreign objects (nails, staples, imbedded gravel, etc.). If you have any question about the quality of your lumber, do not use it. Remember, wood stacked on a concrete floor can have small pieces of stone or concrete pressed into its surface. • Use the full width of the planer, Alternate between the left, the right and the middle when feeding lumber into the planer. Your knives will remain sharp much longer. • Scrape all glue off of joined boards before planing. • Plane ONLY natural wood fiber (i.e. DO NOT plane wood composites). • Surface wood with the grain. NEVER feed end-cut or end-grained lumber into your planer. • DO NOT use boards with knots, splits, cross- grain or other obvious blemishes or defects. They can damage the machine and pose the possibility of operator injury. • Keep your work area clear. • Avoid planing wood with a high water content. Wood with more than 20% moisture content or wood exposed to rain or snow will plane poorly and cause excessive wear to the knives and the motor. Excess moisture can also hasten rust and corrosion. • During operation, always use the table height lock knob for consistent and accurate results. • Always true any cupped or warped stock on a jointer before planing. Extreme Duty Planers -17 Wood Characteristics The species of wood, as well as condition, will affect planing ability—the harder the wood, the more difficult it will be to plane. We have included a list of wood characteristics you may encounter when planing, The following descriptions of defects will give you some possible answers to problems that may arise. Chipped Grain (Tear Out) — Usually a result of cutting against the grain, or planing wood with knots or excessive amount of cross grain. Chipped grain can also be caused by dull knives or misaligned chip breaker. Often, chipped grain can be avoided by slowing down the feed rate and by taking shallow cuts, If those options do not work, inspect your lumber and determine if its grain pattern is causing the problem. If the wood does not show substantial crossgrain, inspect your knives for sharpness and inspect the chip breaker for proper alignment. Fuzzy Grain (Raised Grain) — Usually caused by surfacing lumber with too high of a moisture content. Sometimes fuzzy grain is a characteristic of wood such as basswood. Fuzzy grain can also be caused by dull knives or an incorrect grinding bevel. Check with a moisture meter. If moisture is greater than 20%, sticker the wood and allow it to dry. Otherwise, inspect the knife condition. Glossy Surface — Usually caused by dull knives taking shallow cuts at a slow feed speed. Surface gloss will usually be accompanied by overheating. Lumber will often be scorched and eventually damage to the knives will occur. If the knives are sharp on inspection, increase feed speed or cu...
