Page 3: Rules For Safe Operation
CAUTION: Failure to obey safety warning may result in serious injury to yourself or to others. Always follow the safety precautions to reduce the risk of fire, electric shock, and personal injury. NOTE: Advise you of information or instructions vital to the operation or maintenance of the equipment.
Page 4 accidents. 4. DO NOT USE IN DANGEROUS ENVIRONMENTS. Do not use power tools near gasoline or other flammable liquids, in damp or wet locations, or expose them to rain. Keep the work area well lighted. 5. KEEP CHILDREN AWAY FROM POWER TOOLS. All visitors should be kept at a safe distance from the work area.
Page 5 source. 22. STAY ALERT. Never operate a power tool when tired or while under the influence of drugs, alcohol, or medication. 23. MAKE SURE A TOOL IS CONNECTED only to the voltage marked on the nameplate. 24. NEVER USE A TOOL if its cover or any bolts are missing. If the cover or bolts have been removed, replace them prior to use.

12. DO NOT FORCE-FEED THE WORK PIECE through the machine. Let the sander apply the proper feed rate. 13. CHECK THE FEED BELT occasionally to make sure there is no debris or sawdust between any components. 14. SAND ONLY SOUND LUMBER; there should be no loose knots and as few tight knots as possible.
Page 7: Extension Cords
EXTENSION CORDS When using a power tool at a considerable distance from a power source, use an extension cord heavy enough to carry the current that the tool will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and overheating.
Page 8 can be removed in a single pass. DRUM SANDING ADVANTAGES One advantage of the wide drum sander is that you can work with material up to 405mm wide with this unit because of its open side design. Although you still abrasive sand with the grain, you do not have to read the grain to prevent tear-out.
Page 9: Loose Parts List
WOOD SPECIES TO BE CAUTIOUS WITH Highly resinous species will tend to quickly clog (load-up) abrasives and in many cases abrasive loading cannot be removed with belt cleaning sticks. The most notorious abrasive loaders are some common pine species. It is nearly impossible to clear the abrasive of the pitch, sap sawdust combination.

counterclockwise while the nut is held with the wrench. (See Figure 15.) 3. If the conveyor feed belt is tracking towards the inboard (motor side) of the machine, tighten (add tension) to the tracking adjustment screw on that side of the machine. NOTE: Due to the width of the conveyor feed belt, tracking adjustments may not become apparent immediately! Increase the speed of the conveyor feed belt to hasten the effects of your adjustments.
Page 20 of the material being surfaced, and the feed rate selected are all considered when determining the amount of material to be removed on each pass. Never remove more than 0.8mm of material in one pass. The variable feed rate is set to prevent burning and provide a smooth sanded surface on different types and widths of materials.
Page 21 INSTALLING NEW REPLACEMENT ABRASIVE STRIPS WARNING: To prevent possible serious personal injury, always disconnect the Wide Drum Sander from the power source before serving the unit or changing the abrasive strips. Abrasive strips are available from local dealer in precut strips which require no special measuring or trimming before installation.
Page 22 your left hand while holding tension on the abrasive strip with your right hand and guiding the material onto the drum. Use this technique to warp the abrasive strip edge to edge radially around the drum. Make sure you do not overlap the material as you wrap the abrasive (Figure 16). The material should be flush to slightly gapped, but not overlapped, during the wrap.
Page 23 NOTE: In some cases, if the abrasive strip stretches, it may be necessary readjust/reposition the abrasive clip points on the abrasive strip. Ensure the tension remains positive on the abrasive strip during extended use. ABRASIVE GRIT SELECTION THE SANDING PROCESS Smoothing wood, or sanding, is the process of making finer and finer scratches until they become so small they are no longer visible to the human eye.
Page 24: Maintenance Of Unit
MAINTENANCE OF UNIT WARNING: To prevent possible serious personal injury, always disconnect the Wide Drum Sander from the power source before serving the unit or changing abrasive strips. Keep your Wide Drum Sander clean. Remove accumulated sawdust from the drum and other working parts. Frequently clean resin buildup from the inner drum using a kerosene or a resin remover dampened cloth with the unit disconnected from the power source.
Page 25 and the abrasive strip must be replaced. 1. Heed all warnings and use extreme caution when performing this cleaning operation. 2. Set the conveyor belt speed control knob to lowest feed setting. Avoid contact with conveyor feed belt. 3. Open the protective dust cover to expose the sanding drum and abrasive strip.
