manual abstract
Large knots can cause kickback and machine damage. Choose workpieces that do not have large/loose knots when planing. • Wet or "Green" Stock: Avoid planing wood with a high water content. Wood with more than 20% moisture content or wood exposed to excessive moisture (such as rain or snow), will plane poorly and cause excessive wear to the cutterhead and motor. Excess moisture can also hasten rust and corrosion of the planer and/or individual components. • Excessive Warping: Workpieces with excessive cupping, bowing, or twisting are dangerous to cut because they are unstable and often unpredictable when being planed. DO NOT use workpieces with these characteristics! • Minor Cupping: Workpieces with slight cupping can be safely supported if the cupped side is facing the planer table. On the contrary, a workpiece supported on the bowed side will rock during planing and could cause severe injury from kickback. Model G1033X (Mfg. Since 4/12) The species of wood, as well as its condition, greatly affects the depth of cut the planer can effectively take with each pass. The chart in figure 14 shows the Janka Hardness Rating for a number of commonly used species. The larger the number, the harder the workpiece, and the less material to be removed in any one pass for good results. Note: The Janka Hardness Rating is expressed in pounds of force required to embed a 0.444" steel ball into the surface of the wood to a depth equal to half the ball's diameter.

Janka Hardness Rating for some common wood species. -23- Species Janka Hardness Feed Rate Depth of Cut NOTICE Only change the feed rate when the planer is running, but DO NOT attempt to change the feed rate during any cutting operations or damage to the gearbox will result. The infeed and outfeed rollers move the workpiece through the planer while keeping it flat and providing a consistent rate of movement. Use the two feed rates as stated below: Low Feed Rate..........................Dimension Pass High Feed Rate............................Finishing Pass Figure 15 illustrates the three different positions of the feed rate control knob: • Push the knob in to use the high feed rate (20 FPM). • Pull the knob out to use the low feed rate of 16 FPM. • Move the knob to the center position to place the gearbox in neutral. The planing depth of cut is controlled by using the table height handwheel on the right side of the machine. Rotating the handwheel clockwise raises the table. The depth of cut is read directly from the inch/millimeter scale on the front of the planer, as shown in figure 16. figure 16. Depth of cut indicator and scale. One complete turn of the handwheel raises or lowers the table approximately Vie". The range of material thickness that can be planed is W'^/V'. Although the correct depth of cut varies according to wood hardness and workpiece width, we recommend a maximum depth of cut no more than Vie". A series of light cuts will give a better end result and put less stress on the planer than trying to take off too much material in a single pass. Acaution No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. failure to do so could result in serious personal injury, damage to equipment, or poor work results. -24- Model G1033X (Mfg. Since 4/12) bed Rollers To adjust the bed rollers: Bed Roller Height Range..............0.002"-0.020" Tools Needed: Qty Hex Wrench 3mm..............................................i Open End Wrench 14mm..................................i Rotacator (optional, Page 26)...........................1 The height of the bed rollers will vary, depending on the type of material you intend to plane, However, as a general rule, keep the roller height within 0.002"-0.020" above the table surface, as illustrated in figure 17. When planing rough stock, set the rollers high to keep the lumber from dragging along the bed. When planing milled lumber, set the rollers low to help minimize snipe. To ensure accurate results and make the adjustment process quicker and easier, we recommend using a Rotacator (see Page 26) to gauge the bed roller height from the table. if a Rotacator is not available, a straightedge and feeler gauges can be used, but extra care must be taken to achieve satisfactory results. Note: Misaligned bed rollers can cause workpiece chatter, a washboard surface, uneven workpiece feeding, or binding. 1. DiSCONNECT PLANER FROM POWER! 2.
