Wear ear protectors (plugs or muffs) during extended periods of operation. This drum sander is to be used with wood and wood products only. Use of this drum sander and a dust collector with metal products is a potential fire hazard. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead based paint. • Crystalline silica from bricks, cement and other masonry products. • Arsenic and chromium from chemically treated lumber. Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles. Do not operate this sander while tired or under the influence of drugs, alcohol or any medication. Make certain the switch is in the OFF position before connecting the machine to the power supply. Always sand with the grain of the wood. Always feed stock against the rotation of the drum. Do not sand pieces of material that are too small to be safely supported. When sanding a large piece, provide additional support at table height. Always connect and use a dust collector to the drum sander while operating. Make certain the machine is properly grounded. Make all machine adjustments or maintenance with the machine unplugged from the power source. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on. Keep machine guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately. Make sure the drum sander is firmly secured to the stand or bench before use. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function - check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. Provide for adequate space surrounding work area and non-glare, overhead lighting. Keep the floor around the machine clean and free of scrap material, oil and grease. Keep visitors a safe distance from the work area. Keep children away. Make your workshop child proof with padlocks, master switches or by removing starter keys. Give your work undivided attention. Looking around, carrying on a conversation and "horse-play" are careless acts that can result in serious injury. Warnings ii _ii' 29. Stand to one side of the conveyor and make sure no one else is standing in line with the conveyor while feeding into the machine. The drum sander operates at high speed and should a part slip, it will exit the machine at a high rate of speed and may result in injuries to anyone standing directly in front of the infeed. (Keep the conveyor belt clean and check pin-roll adjustments). Maintain a balanced stance at all times so that you do not fall or lean against the sanding drum or other moving parts. Do not overreach or use excessive force to perform any machine operation. 30. Use the right tool. Don't force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and safer at the rate for which it was designed. 31. Use recommended accessories; improper accessories may be hazardous. 32. Maintain tools with care. Keep tools sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories. 33. Never brush away sawdust while the machine is running. Use the correct speed and feed for the tool. Be sure that the tool is the correct one for your operation. 34. Never stand on a machine. Serious injury could occur if the machine tipped or if the sanding drum is unintentionally contacted. 35. Never leave the machine running unattended. Turn the power off and don't leave the machine until it comes to a complete stop. 36. All doors should be closed, all panels replaced and other safety guards should be in place before the machine is started or operated. 37. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it begins to feed into the machine, causing a pinching action between the part and the table. Use caution! Hands should be clear of the stock and the table to avoid pinching. Never reach into a running machine. Turn off the electrical power and stop the machine before attempting to retrieve parts from within it. Keep your hands away from the sanding area. Contact with internal moving parts can result in the loss or injury to fingers, hands and arms. 38. Remove loose items and unnecessary work pieces from the area before starting the machine.

Grounding IACAUTION _jjjjjjjjjjjjjjjjj__ Instructions _ This tool must be grounded while in use to protect the operator from electric shock. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. 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 the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor, with insulation having an outer surface that is green with or without yellow stripes, is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept the tool's plug. Repair or replace a damaged or worn cord immediately. 115 Volt Operation As received from the factory, your sander is ready to run at 115-volt operation. This sander, when wired for 115 volts, is intended for use on a circuit that has an outlet and a plug that looks the one illustrated in Figure A. A temporary adapter, which looks like the adapter as illustrated in Figure B, may be used to connect this plug to a two-pole receptacle, as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should only be used until a properly grounded outlet can be installed by a qualified electrician. This adapter is not applicable in Canada. The green colored rigid ear, lug, or tab, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box, as shown in Figure B. THREE-PRONG GROUNDING Q PLUG GROUNDING EAR WITH SCREW PRONG GROUNDED OUTLET Q The use of an extension cord is not recommended. However, if you must use one make sure your extension cord is in good condition. Be sure to use one heavy enough to carry the current your machine will draw. An undersized cord will cause a drop in the line voltage resulting in power loss and overheating. The following table shows the correct size to use depending on the cord length needed and the nameplate ampere rating, tf in doubt, use the next heavier gauge. Remember, the smaller the gauge number, the heavier the cord.

Note: The figures shown in this manual may display the Performax 10-20-Plus Drum Sander with several optional accessories. To purchase any of these accessories contact your dealer. 1. Attach the handwheel (Figure 1, Item A) to the height adjustment screw and tighten. Figure 1 On/Off Switch I Before powering up the unit, make sure all of the tools used to assemble and adjust the unit are removed and accounted for. Make sure your hands, loose clothing and any other items that may get caught are safely away from the unit. The On/Off Switch (Figure 2, Item A) is located on the front of the sander. To turn the sander on, pull the switch to the on position. To turn the sander off, push the switch to the off position. Switch Lock The sander can be locked from unauthorized use by locking the switch. To lock the switch: 1. Turn the switch to the off position and disconnect the sander from the power source. 2. Pull the key (Figure 2, Item B) out. The switch cannot be turned on with the key removed. I Should the key be removed from the switch in the on position, the switch can be turned off but cannot be turned back on. 3. Circuit To replace the key, slide the key into the slot on the switch until it snaps. Breaker The sander is equipped with a motor protective device (circuit breaker). The breaker will automatically shut the sander off when excessive current is consumed. If the breaker is tripped, turn the sander off and reset the circuit breaker by pressing the button (Figure 2, Item C). I Be sure to turn the sander off before resetting the circuit breaker to avoid unintentionally starting the sander A Figure 2 This Page Intentionally 10 Left Blank I Conveyor Belt Tracking Belt tracking adjustment may be necessary during the break-in period and normal operation to compensate for belt stretching. Abrasive belt tension must be properly adjusted before adjusting the tracking. Adjust the belt tracking while the conveyor belt is running at its fastest speed. Tighten the hex nut (Figure 5, Item B) on the side the belt is drifting towards, and loosen the hex nut on the opposite side. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts. Note: Adjustment should be made in 1/4 turns of the hex nut. Allow time for the belt to react to the adjustment. Do not over adjust. Conveyor Figure Belt Tension Conveyor belt tension adjustment may necessary during the break in period compensate for belt stretching. be to If the conveyor belt can be stopped by hand pressure applied directly to the top of the conveyor bed, the belt is too loose. Insufficient belt tension will cause slippage of the conveyor belt on the drive roller during sanding operations. Excessive belt tension can cause tracking problems and result in bent rollers, bent take-up brackets and premature conveyor belt wear. Adjust the hex nuts (Figure 5, Item B) on both sides of the conveyor to obtain a tight, and equally tensioned, conveyor belt. Use the attached wrenches (Figure 5, Item C) to adjust the hex nuts. Drum Height Control Drum height is controlled by the height adjustment handle (Figure 5, Item A). Turning the handwheel in a counterclockwise direction lowers the drum. Turning the height adjustment handwheel one revolution lowers the drum approximately 1/16". 11 5 Checking Turn the board 180 degrees and sand the same side without changing the sanding height. Drum Alignment The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, follow the instructions listed below. . Lift the knob (Figure 6, Item A) to open the dust cover and remove the abrasive strip. If you are unsure how to do this, see the "Wrapping Abrasive Strips" section in this manual. . Using a metal straight edge, or ruler, as a thickness gauge (Figure 6, Item B), insert the gauge between the drum and the conveyor bed on the outer end of the drum. . . Open the dust cover and lower the sanding drum while slowly rotating the drum by hand until the drum lightly contacts the thickness gauge. Remove the thickness gauge and place it under the drum at the opposite end. If the drum does not contact the thickness gauge to the same degree as the other end of the drum, alignment is necessary. Aligning the Drum 1. Loosen the two hex cap bolts (Figure 7, Item C). 2. Lay the thickness lengthwise. . 4. If a ridge is visible where the drum overlaps, loosen the two hex cap bolts (Figure 7, Item C) and turn the adjusting knob (Figure 7, Item D) slightly. Turn the adjusting knob clockwise to lower the outboard end of the drum and counterclockwise to raise it. Tighten the two hex cap bolts. Repeat this process until the ridge is gone and the entire board is sanded. Figure 6 gauge under the drum Adjust the knob, (Figure 7, Item D) until the drum contacts the gauge equally along its entire surface. Turn the adjusting knob clockwise to lower the outboard end of the drum, and counterclockwise to raise the outboard end of the drum. When the drum is parallel to the conveyor, tighten the two hex cap bolts. Fine Tuning C Drum Alignment When sanding boards wider than the drum, drum alignment is critical and must be adjusted slightly higher on the outboard end. This will prevent any ridges from developing in the stock. Always check it on a piece of scrap wood, as follows, before sanding the work piece. Figure 7 Run a piece of scrap wood approximately 6" wide by 16" to 18" long through the sander sideways so that the end of the board extends past the end of the drum. 12 Wrapping Abrasive Strips Note: When using Performax "Ready to Wrap" and "Ready to Cut" abrasives, not all of the steps below are necessary. You can use the original abrasive belt that came with the sander as a template for cutting your own strips. I SandPaper 1. Mark and cut a taper at one end of the roll, as shown in Figure 8. 2. Square off the end of the taper, as shown in Figure 8. . Squeeze the fastener lever (Figure 9, Item A) on the outboard end of drum, and insert the tapered end of the abrasive (Figure 9, Item B) so that it uses most of the width of the slot. Release the fastener lever to securely hold the strip end to the fastener. 4. The square edge of the abrasive strip should follow the edge of the drum, as shown in Figure 9. 5. Wrap the abrasive strip around the drum, being careful not to overlap the windings, as shown in Figure 10. 6. Mark the trailing end of the strip where it crosses the inboard end of drum (Figure 11, Item C). . Remove the abrasive strip and cut a taper as was done with the starting edge, (See Figure 8). Note: The taper on the remaining roll can be used as the taper for the starting edge of the next strip to be cut. 8. . St[ P '-_:_ Figure 8 F_u_ 9 Rewrap the drum starting at the left side as described in steps 3-5. Squeeze the inboard end of tapered end through the fastener. fastener lever on the the drum, and insert the of the abrasive strip slot into the take-up Position the abrasive Figure 10 strip IM P O RTAj_j_j_j_j_jT N with sufficient room between the inside of the slot and the tapered end of the strip to allow it to be pulled into the drum as needed, (See Figure 12). 13 Figure 11 __ Using the TUF Tool TM The Tuf Tool (Figure 13) can also be used to hold the take-up fastener in place while you feed the sandpaper through the slot. Figure 13 . Clip the sandpaper into the outboard fastener. Wrap the drum, being careful not to overlap the windings. Hold the sandpaper over the inboard slot with the left hand. Figure . . 12 Hold the TUF Tool with the red end of the tool pointing away from you (Figure 14). Insert the hook into the hole in the end of the take-up lever of the fastener (Figure 14). Lift the lever with the TUF Tool, pulling the lever up until it touches the inside of the drum. Turn the TUF Tool counterclockwise and lower it onto the sandpaper, making sure it is holding the sandpaper tight and opening the throat of the fastener (Figure 15). . Insert the tapered end of the paper into the slot and the fastener, tt may be necessary to trim the tapered end of the paper so it does not "bottom out" against the inside of the drum. Be sure to leave a gap of at least 1/8" between the tapered strip and the closed end of the slot to allow the strip to be pulled into the fastener as needed (Figure 15). If necessary trim the outside edge of the paper. . Hold the sandpaper in place with your left hand. Rotate the drum toward you slightly. Pull up on the TUF Tool and turn the handle clockwise while maintaining upward pressure. Slowly move the TUF Tool away from you slightly, then down, while easing it out of the hole. This releases the lever into its proper position. (Figure 16). Figure 14 Figure 15 All abrasive strips will stretch with use and may stretch enough to allow the take-up lever to reach its lowest position so it cannot maintain tension on the strip. If this occurs, follow the above procedures to reset the take-up lever. Figure 16 14 Connecting Sander to a Dust Collector Establishing Dust collection is necessary for all drum sanders. The Performax 10-20 is equipped with a 4" dust collection port in the back of the dust cover, and is designed to be used with a standard dust collector as shown in Figure 17. Drum Height To establish the proper drum height, place the board to be sanded under the drum and lower the drum until it just touches the board. Note: The sanding drum should still rotate by hand. Without changing the drum height, finish feeding the stock under the sander. Start the sanding drum and sand the board at that same position. JET offers a variety of Dust Collectors and Air Filtration Units that will work nicely with your new sander. Contact your local distributor for more information. Setting the Proper the Depth Gauge The depth gauge indicates the distance from the bottom of the drum to the top of the conveyor. 1. Lower the drum, with the sandpaper installed, until it touches the conveyor. 2. Loosen the screw (Figure 18, Item B). 3. Adjust the pointer (Figure 18, Item C) to read zero and tighten the screw. Note: depending on the desired accuracy, you may need to repeat this process when installing different sandpaper grits. Setting Figure 17 the Depth of Cut Adjusting the Performax 10-20 for proper contact between the abrasive and the stock is the most important set-up procedure before operating the sander. It may take some experimentation to determine the proper depth of cut, given the variables of abrasive grit and types of wood. For best results, use scrap wood to practice sanding and to develop your skills and familiarity with the machine before doing any finish work. A good rule of thumb when sanding with grits finer than 80 is lower the drum so that it contacts the work piece but can still be rotated by hand. When using grits coarser than 80 grit, you can lower the drum slightly more. However, a combination of several variables will determine the proper depth of cut to use, including the following: • • • • Figure 18 Abrasive type and grit size. Width of the piece being sanded. Hardness of the piece being sanded. Feed rate of the piece being sanded. 15 pass, whether you are doing abrasive planing, cleaning up glued panels or flattening stock. Grits from 100 through 220 are primarily finishing grits designed to remove the scratch pattern from the previous grit used. For best results, never skip more than one grit grade when progressing through a sanding sequence. Abrasives The abrasive material you choose will have a substantial effect on the performance of your sander. Variations in paper type, weight, coating and durability all contribute to achieving your desired finish. For the best sanding results, Performax offers premium abrasives that have been tested and certified for lowest overall cost and maximum performance. Genuine Performax abrasives are available in pre-cut "Ready- toWrap" lengths or in the convenient pre-marked "Ready-to-Cut" box. Selecting For fine work, such as furniture, try not to skip any grit grades during the sanding process. In general, premium quality abrasives such as genuine Performax abrasives will produce a better finish with a less noticeable scratch pattern. Note: Grits that are too fine can sometimes burnish the wood and leave a glossy surface that will not accept stains evenly. This will vary by the type of wood. Oak, for example, is susceptible to burnishing because of its open pores. Drum Abrasives To achieve maximum sanding results, it is important to select the proper grit of abrasive for the type of sanding being performed. As with any sanding operation, first begin sanding with a coarser grit, depending on the roughness of the stock, or the amount of stock to be removed. Then progressively work toward finer grits. The chart below shows the general uses for the various grits. Performax offers strip rolls in the nine different abrasive grits shown.

To use, operate the sanding drum with the dust cover open. For your own safety, always wear eye protection while performing sandpaper cleaning, and take all precautions to avoid any contact of hands or clothing with uncovered drums. Hold the cleaning stick against the rotating drum and move it along the drum surface. It is a good idea to use a shop brush or air nozzle to remove any cleaning stick crumbs from the drums before resuming sanding operations.

Stretching Abrasive Life Abrasive life can also be increased by removing the abrasive strip from the drum and reversing it. To do this, remove the strip and use what was the trailing end as the starting end on the left (outboard) side of the drum. Reversing the strip will provide a fresh set of cutting edges on the drum. Grits The amount of stock to be removed is a major consideration when choosing the grit grade to start with. Grits of 24, 36, 50, 60 and 80 are primarily designed for stock removal. Grits of 24 and 36 will remove the most material in one 16 Performax 10-20 Abrasives "Ready-to-Wrap" cut wraps. good procedure to stack and clamp several pieces together to prevent them from slipping, or tipping. 24-220 Grit contains six pre- Sanding Ready-to-Wrap 60-1024 ............ 60-1036 ............ 60-1060 ............ 60-1080 ............ 60-1100 ............ 24 Grit 60-1120 36 Grit 60-1150 60 Grit 60-1180 80 Grit 60-1000 100 Grit ............ ............ ............ ............ 120 150 180 220 Grit Grit Grit Grit Ready-to-Cut (Aluminum oxide) 60-9036 ............ 36 Grit 60-9120 ............ 60-9060 ............ 60 Grit 60-9150 ............ 60-9080 ............ 80 Grit 60-9180 ............ 60-9100 ............ 100 Grit60-9220 ............ 120 150 180 220 Grit Grit Grit Grit Feeding Face Frames Angle Monthly When finish sanding, the work piece should be fed through in line with the grain on the final one or two passes for the optimum finish. Sanding and Raised Panel Doors It is very important to have the proper abrasive contact when doing this type of sanding, tf the sander is set to take an excessive depth of cut, the result can be a gouge, or dip as the drum goes from sanding the rails at full width to sanding just a few inches of width on the stiles. To prevent this problem, make sure that when using abrasives finer then 80 grit, the drum is in contact with the wood but can still be spun by hand. The optimum stock feeding angle, when sanding, is at a 60-degree angle. However, even a slight stock feeding angle will provide more effective stock removal, less loading of abrasives, longer abrasive life, potentially faster feed rates and reduced motor loads. Multiple-Piece Stock When sanding stock with a cup or crown, place the crown up. This will stabilize the stock to help prevent tipping or rocking during sanding. (After the crown has been removed and the top is flat, turn the stock over and sand the opposite side.) To avoid personal injury, take special care when sanding stock that is twisted, bowed or otherwise varies in thickness from end to end. If possible, support such stock as it is being sanded to keep it from slipping, or tipping. Use extra roller stands, help from another person, or hand pressure on the stock to minimize potentially hazardous situations.

This way you will be able to determine the thickness of the thinnest piece and process all pieces to that same thickness. Be aware that the sander will remove cups and crowns in the work piece; consider this when measuring the processing stock to the same thickness. • Lubricate the conveyor check for wear. bushings and • Lubricate all moving parts, such as threaded rods, washers and bushings. • Clean the sawdust from the conveyor belt and sanding drum. Blow the dust from the motors and switches. Blow the dust from the inside of the sanding drum to prevent vibration. Be careful not to disturb the drum balancing weights. Edge Sanding When edge sanding, the Performax sander will mimic the opposite edge of the stock which is lying on the conveyor belt. Because of this, it is important for the stock edge to have been ripped at the proper angle to the face before the sanding process. When edge sanding stock that is less than 3/4" wide, or more than 2" high, it is • 17 Check all the setscrews for tightness on parts such as bearings, the conveyor and couplings. Conveyor Belt Replacement Drum Height To replace the conveyor belt: 1. Disconnect the machine from the power Raise the drum to its highest position using the handwheel (Figure 19, Item A). 3. Remove the belt tension by loosening both take-up nuts (Figure 19, Item B). 4. Unscrew the three screws (Figure 19, Item C) that attach the conveyor to the bracket. 5. Unbolt the two hex head bolts (Figure 19, Item D) that hold the bracket to the bench or stand. 6. Slide the conveyor belt off the conveyor and replace it with a new belt. 7. Reverse the procedure for installation. Adjustment If the height control mechanism does not operate easily or smoothly, or there is excessive vertical movement of the drum carriage, perform the following adjustments. SOUrCe. 2. Control 1. To reduce the handwheel backlash, tighten the Iocknut on the height adjustment screw (Figure 21, Item J). 2. Thoroughly lubricate all mating surfaces and height adjustment screw (Figure 21, Item K).

Loosen the two bearing hex nuts (Figure 20, Item F) on the outboard side of the drum and two cap screws on the inboard side (Figure 20, Item G). 3. This will allow the tension rollers to drop to their lowest position. 4. Lower the sanding drum touches the conveyor bed. 5. Turn the drum height handle one complete revolution to raise the drum. 6. Retighten the bearing hex nuts and the cap screws. Tension Roller Pressure Figure 19 so that it just Figure 20 Adjustment You can also adjust the spring-loaded screws (Figure 20, Item H) found on the pressure roller brackets, to increase or decrease roller pressure. If you are getting snipe marks at the leading end of the board adjust the outfeed roller pressure. If the snipe marks occur on the trailing end of the board, adjust the infeed roller pressure.
