OPERATION DEPTH GAGE See Figure 13. The depth gage indicates the amount of wood being removed in a planing pass. The workpiece must be positioned under the depth gage on the front of the planer. Never make a planing cut deeper than: I 1/8 in. (3 mm) for material up to 6 in. (152 mm) wide I 1/16 in. (1.6 mm) for material 6 in. (152 mm) - 13 in. (330 mm) wide Do not continuously use the planer at the maximum depth of cut ,1/8 in. (3 mm), as it will damage the motor. REPLANING See Figure 14. Your planer has a replane feature using preset markers for repetitive planing. The replane indicator allows you to plane material at a set measurement of 1/4 in. (6 mm). The maximum depth of the replane indicator is 1-3/4 in. (44 mm). I Push cutter lock to the left to unlock cutter head assembly. I Raise cutter head assembly to a height greater than 1-3/4 in. (44 mm). I Move the replane set knob to the desired height. I Lower the cutter head assembly until it stops. I Lock cutter head in place by pushing cutter lock handle to the right. AVOIDING SNIPE Snipes, or depressions made at either end of a workpiece by cutter blades, can occur when the board is not properly supported. Engaging the cutter lock before planing will minimize snipe. Although snipe may be barely noticeable, it is important to keep the workpiece parallel and flat with the planer table to minimize snipe. Butting workpieces end-to-end as they are fed through the planer will minimize the problem, especially for shorter pieces, because it provides a more stable feed. For workpieces longer than 48 in. (122 cm), greater care must be taken to reduce the problem because the additional length means more of the total weight is unsupported by the planer table and rollers causing the shifting weight to work against keeping the stock flat. To remove snipe from a finished workpiece, cut off the end of the workpiece where snipe is noticeable. DEPTH GAGE 111---113///424 1/4 0 Fig. 13 Avoid using severely warped wood as it can jam the planer. If it must be used, rip it in half before planing to help minimize the possibility of jamming. If jamming does occur, turn the switch off and unplug the planer immediately. Raise the cutter head assembly high enough to remove the workpiece easily. Carefully check to make sure no damage to the tool has occurred before making the next planing pass. Always feed the workpiece in the direction of the grain. This allows the cutter blades to sever the wood fibers instead of tearing them. Feeding against the grain can also cause the cutter blades to chip the workpiece. CUTTER HEAD ASSEMBLY WARPED WOOD Little or no warpage is the ideal condition for planing a workpiece. Simply turn the workpiece over and plane it to the desired thickness. Otherwise, plane the top flat first, turn the workpiece and plane the bottom half. For a board that is cupped or bowed across its width, the best method is to rip the board lengthwise down the middle and plane the pieces separately. This method eliminates much of the waste in planing cupped or bowed workpieces. The only way to remove the bow from a workpiece that is cupped or bowed down its length is to use a jointer.
