Normal loads will be handled safely on voltages not more than 10% above or below the specified voltage. The green colored grounding lug extending from the adapter must be connected to a permanent ground, such as a properly grounded outlet box. 3. Running the unit on voltages which are not within the range may cause overheating and motor burnout. Make sure this is 4. Heaw loads require the voltage at motor terminals be not less than the voltage specified. I connected to a known ADAPTERI GROUNDING INSTRUCTIONS This tool is equipped with a three-conductor cord and ground type plug which has a grounding prong, approved by Underwriters Laboratories and the Canadian Standards Association. Do not remove or alter the grounding prong in any manner. In the event of a malfunction or breakdown grounding prov des a path of least resistance for electrical current to reduce the risk of electrical shock. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided. If it will not fit in the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of e_ectrical shock. The conductor with insulation having a green outer surface is the equipment-grounding conductor. If repair or replacement of the electrical cord or plug is necessary, make sure the equipment-grounding conductor is not connected to a line terminal. Check with a qualified electrician or service personnel if the grounding instructions are not understood, or if in doubt as to whether the tool is properly grounded. The tool has a three-prong plug, such as the one illustrated. This tool is intended for use on a circuit having a nominal rating less than 150 volts which has an outlet that looks like the outlet illustrated. 3-PRON__gr°und receptacle. / __ I_ GROUNDING LUG NOTE: The adapter illustrated is for use only if you already have a properly grounded two-prong receptacle. Adapter is not allowed in Canada by the Canadian Electrical Code. EXTENSION CORDS 1. The use of any extension cord will cause some drop in the voltage and loss of power. 2. The wires of the extension cord must be sufficient in size to carry the current and maintain adequate voltage. 3. Use the table below to determine the minimum wire size (A.W.G.) extension cord. 4. Use only three-wire extension cords which have three-prong grounding type plugs and three-pole receptacles which accept the tool plug. 5.

Additional parts which need to be fastened to the unit should be located and accounted for (See Figure 2), 2. The handwheel attaches to either end of the crank shaft. CONTENTS _oo,,_ ...... _T 3. The knife gauge is provided for removal and adjustment of the knives. 4. Adjusting tools are also !ocated in the parts bag. CAUTION: DO NOT ATTEMPT ASSEMBLY IF PARTS ARE MISSING. USE OWNER'S MANUAL TO ORDER REPLACEMENT PARTS. *........ .! _ Figure 2 ASSEMBLY CLEAN THE PLANER Assembly and adjustment procedures are easier to perform on a clean unit. Unpainted steel surfaces have been coated with a shipping preservative. Remove the preser,,ative with kerosene or penetrating oil. Use soap and water on ruboer and plastic parts. Cleaning fluids tend to deteriorate them. Non-flammable solvents are recommended. INSTALL HANDWHEEL Refer to Figure 4. 1. The handwheel attaches to the shaft (Key No. 17) for cutterhead adjustment. 2. Place key (Key No. 44) into slot on shaft. 3. Slide handwheel (Key No. 21) onto shaft. Fasten the handwheel to the shaft with bolt (Key N0.24). INSTALL KNIFE GUARD Refer to Figure 5. 1. The knife guard (Key No. 20) attaches to the roller case. The knife guard directs the flow of chips removed from the Workpiece and protects against unintentional contact with the cutterhead. WARNING: KNIFE GUARD MUST BE FASTENED SECURELY PRIOR TO ANY TIME THAT THE PLANER IS PLUGGED IN TO PROPERLY GUARD AGAINST ACCIDENTAL CONTACT WITH THE CUTTERHEAD, 2. Fasten the I_nife guard using the two socket head bolts and lock washers (Key Nos, 29 & 34). MOUNT PLANER TO WORK SURFACE Refer to Figure 5. 1. The planer is designed to be portable so it can be moved to the job site, but it should be mounted to a stable, level bench or table. 2. The base of the planer has mounting I_oles in it. These holes form a rectangle 17 3/4" x 7 1/2". Use a square to mark the position on the work surface. Mount the planer to the work surface by bolting it through the holes. 4. Drill pilot holes in suffacefor mounting with lag bolts (Key No. 41). 5. Insert bumpers (Key No. 42) into bottom of the base. Fasten planer with lag bolts (Key No. 41) thi'ough mounting holes. OPERATION SAFETY PRECAUTIONS ADJUSTING THE DEPTH OF CUT WARNING: Always observe the following safety precautions. Whenever adjusting or replacing any parts on the planer turn the switch off and remove the plug from the power source. Check that all fasteners are securely tightened. Make sure guards are properly attached. Guards should be fastened securely and working properly. Make sure that the knives are aligned and properly attached to the cutterhead. Refer to Figure 5. The height of the cutter blades is shown by indicators (Ref. N0.24) located on either side of the planer in-feed roller support, The indicators ride on scales (Ref. No. 25) to show the thickness of the planed board. Be certain that all moving parts are clear of interference. Check that knives rotate freely without obstruction. Do not plug the planer in unless the switch is in the "off" position. After turning the switch on, allow the planer to come to full speed before operating. Keep hands clear of all moving parts. Do not force the work into the knives. Allow the automatic feed to work properly. Replace or sharpen knives when they become damaged or dull. Always wear eye protection. DEPTH OF CUT Thickness planing refers to the sizing of lumber to a desired thickness while creating a level surface parallel to the opposite side of the board. The quality of thickness planing depends on the operator's judgement about the depth of the cut. The depth of the cut depends on the width, hardness, dampness, grain direction and grain structure of the wood. The maximum thickness of wood which can be removed in one pass is 3/32". For optimum planer performance the depth of the cut should be less than 1/16". The board should be planed with shallow cuts until the work has a level side. The thickness is adjusted by rotating the handwheel (Key No. 21) towards the front of the machine to raise the knife height. To reduce the knife height, towards the back. rotate the handwheel Do not set the knife below 13/32". Do not plane a board which is less than 1/2" thick. The knife height will be moved 1/16" with every complete revolution of the handwheel. The action between the crank shaft (Key No. 17) and the elevation screws (Key Nos.8,9) is coupled with beveled gears. If play develops in the action of the handwheels, the gears have become misaligned. One or both of the gears (Key No.12) on the elevation screws must be repositioned to eliminate the play. Lower the knife height to access the bevel gears. Loosen the set screw (Key No.13) and firmly hold the gears together. Tighten the set screw to lock the position. When the depth of cut adjustment is operating correctly, make sure that the indicator is positioned correctly. Make a test cut on a piece of wood and measure the thickness produced. Loosen the screw (Key No.22) (Refer to Figure 5) and set the indicator to show the thickness produced. Once an even surface has been created, flip the lumber and create parallel sides. Plane alternate sides until the desired thickness is obtained. When half of the total depth of the cut is taken from each side, the board will have a uniform moisture content and additional drying will not warp it. The depth of cut should be shallower when the work is wider. When planing hard wood, take light cuts or plane the wood in thin widths. Make a test cut when working with a new type of board or different kind of operation. Check the accuracy of the test cut prior to working on finished product. Figure 3 OPERATION ADJUSTING THE KNIFE HEIGHT Refer to Figure 5. To produce an even surface on a workpiece, the knife edges must be the same distance from the axis of the cutterhead. A knife gauge (Key No.31) has been provided to make knife adjustment more convenient. Remove the cutterheed guard (Ke_ No.20) by removing the fastening bolts (KeyNo.29). Rotate the cutterhead to access one knife. Use caution -the blades are sharp. Position the knife gauge on one side of the cutterheed. Hold the gauge against the cutterhead so the contact point is over the knife (See Figure 3). While holding the gauge, use a hex wrench to loosen the locking bolts. Ad ust the knife by turning the adjustment screw. Turn coiJnterclockwise to ra se the blade. Adjust the blade so it touches the contact point while the gauge is firmly held against the cutter head. Adjust the other side of the blade in the same manner and tighten the locking bolts securely. Adjust the other knife in the same manner. Replace the cutterhead guard and fasten it securely. ADJUST THE BASE ROLLERS Refer to Figure 4. The base of the planer has two rollers in it to improve feed action. The cutterhead of the planer is parallel to the bed of the planer. The workbase rollers (Key No.2) are positioned beneath the feed rollers to compensate for the pressure created by the automatic feed. The height was set during manufacturing, but should be checked occasionally. The rollers should be adjusted about 0,003" above the table surface. Use a straightedge across the two rollers and use a feeler gauge to check the height. Examine the adjustment of the rollers in several spots to determine that both rollers are at the correct level in all spots. If the rollers require adjustment, loosen the set screws (Key No.4) and turn the eccentric adjuster (Key No.3) to position the roller. Re-check the rollers until the proper position is located. Secure the position by tightening the set screw. ADJUSTING THE SUPPORT ROLLERS The support rollers should be adjusted to help keep the portion of the work which is outside the planer in line. Use a straightedge to align the roller plate so the roller height is even with the planer bed. Loosen the nuts (Key No.31) and adjust the height with the hex bolts (Key No.38). Make sure that both of the hex bolts hold the position of the roller plate. Hold the hex bolt with an open end wrench and secure the adjustment by tightening the nut. (Continued) Check the alignment of the support roller at each end with a straightedge.Use the eccentric bushings (Key No.36) to adjust the position of the roller. Lock the position by tightening the socket head bolts (Key No.7). AVOID DAMAGE TO BLADES The thickness planer is a precision woodworking machine and should be used on quality lumber only. Do not plane dirty boards. Dirt and small stones are abrasive and will wear the blade. Remove nails and staples to avoid damaging the blades. The planer should only cut wood. Avoid knots. Heavy cross-grain makes knots hard. Also, knots can come loose an;d jam the blade. CAUTION: Any particle that may encounter the planer knives may be projected from the planer, creating the risk of a hazard. PREPARING THE WORK The thickness planer works best when the lumber has at least one flat surface. Use a surface planer or jointer to define a flat surface. Twisted or severely warped boards can jam the planer. Rip lumber in half to reduce the magnitude of the warp. The work should be fed with the grain. Sometimes the grain will switch directions in the middle of the cut. If possible, cut the board in the middle before planing so the grain direction is correct. CAUTION: DO NOT PLANE A BOARD WHICH IS LESS THAN 12" LONG. THE FORCE OF THE CUT COULD SPLIT THE BOARD AND CAUSE A KICKBACK. FEEDING THE WORK The feed rate refers to the rate at which the lumber travels through the planer. The planer feed is automatic. It will vary slightly, depending on the type of wood cut. The operator is responsible for aligning the work so it will feed properly. Stand on the side of the planer to which the height adjustment handwheel was attached. Lift the work to the in-feed support roller by grasping the edges of the board at approximately the middle of the length. Boards longer than 24" should have additional support from freestanding material stands. Rest the board end on the in-feed support roller and direct the board into the planer. Push slightly on the board and allow the automatic feed to take the board. Release the board and allow the automatic feed to function properly. Do not push or pull on the workpiece. CAUTION: DO NOT STAND DIRECTLY IN LINE WITH THE FRONT OR REAR OFTHE PLANER. WHEN AN OBJECT IS PROJECTED FROM THE PLANER IT WILL TRAVEL IN THIS DIRECTION. OPERATION FEEDING THE WORK (CONTINUED) Move to the rear and receive the planed lumber by grasping it in the same manner as it was fed. Do not grasp any portion of the board which has not g one past the out-feed support roller. Repeat this operation on all the boards which need to be the same thickness or adjust the height. The planer has return rollers on top so an assistant can pass work back to the operator. NOTE: An assistant must follow the same precautions as the operator. The surface that the planer will produce will be smoother if: a shallower depth of cut is used. A snipe is a depression at either end of the board, caused by an uneven force on the cutter head when work is entering or leaving the planer. A snipe will occur when boards are not supported properly (see Adjusting the Support Rollers). A slight snipe may still be noticed when the board is supported. (Continued) An uneven force is created when only one feed roller is in contact with the work at the beginning or end of the cut. The snipe is more apparent when deeper cuts are being taken. When planing more than one board of the same thickness, butt the boards together to avoid the snipe. Feed the work in the direction of the grain. Wood fed against the grain will have chipped, splintered edges. CHECKING FOR WORN KNIVES The condition of knives will affect the precision of the cut. Observe the quality of the cut which the planer produces to check the condition of the knives. Dull knives will tear, rather than sever wood fibers, and produce a fuzzy appearance. A raised grain will occur when dull knives pound on wood that has a varying density. A raised edge will be produced where the knives have been nicked. MAINTENANCE Planer will operate best if it is kept in good condition. Keep the unit adjusted as described in OPERATION. Also, the knives must.be kept clean and sharp to ensure the quality of cut and efficiency of operation. WARNING: MAKE CERTAIN THAT THE UNIT IS D_SCONNECTED FROM THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE_ OR REMOVE ANY COMPONENT. CLEANING THE KNIVES Gum and pitch will collect on knives and cause excess friction when working. Knives will overheat and wear at an accelerated rate. Use a gum and pitch remover to keep blades clean. WHETTING THE KNIVES Knives can be kept sharp by whetting them with a sharpening stone. Remove the cutterhead guard. Partially cover the stone with paper to protect the roller case. Position cutterhead so stone will contact knife along its beveled surface. Stroke the stone across knife from one side to the other while stone is also moved slightly in the direction of the feed. Make sure to do the same number of strokes on both knives. Replace the cutterhead guard. REMOVING KNIVES Knives that are noticeably nicked or worn must be resurfaced to a new beveled edge. Remove knives one at a time. Hold knife with knife gauge (see Figure 3). Loosen the knife locking bolts and remove knives. NOTE: Many shops do not have the capability to resurface knives. The Yellow Pages should list "Sharpening Services" or "Tool Grinding". REPLACEMENT KNIVES Often replacing knives is less expensive than resurfacing them. Keeping a spare set of knives on hand is recommended. Knives should always be sharpened or replaced as a matched set. To replace the sharpened knives reverse the steps used in removing the knives. Adjust knives as described in ADJUSTING THE KNIFE HEIGHT, page 7. LUBRICATION Motor and cutterhead bearings are sealed and need no lubrication. Height adjustment guides and elevation screws should be cleaned of debris and greased when needed. Occasionally apply a few drops of light machine oil to the gibs to keep the roller casing sliding freely in relation to the base. TROUBLE SHOOTING PROBLEM POSSIBLE CAUSE Snipe REMEDY Dull knives 1.
