After returning the platen assembly back to its upright position, retighten the lock bolt depicted in Figure 23. Figure 23. Platen lock bolt. Figure 24. Platen tilted over 90°. Belt tension is preset at the factory and usually requires no adjustment. If the need to increase the tension should occur, unthread the retaining nut at the end of the idler roller mounting shaft. See Figure 25. Do not unthread the nut more than 1.2 its length. If tension problems persist, call the service center for further help. Figure 25. Belt tension mechanism. Operating this equipment has the potential to propel debris into the air which can cause eye injury. Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI).

The back stop can be used for shorter ready to test the machine. workpieces if so desired. Turn on the power supply at the main panel. Press the START button. Make sure that your finger is poised on the STOP button, just in case there’s a problem. The edge sander should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further. If noises occur that can not be found by visual inspection, feel free to contact our service department for help. If the sander runs smoothly, try sanding a piece of lumber. If a problem exists, stop the machine and review all the adjustments. Call for assistance, if needed. Figure 26. Typical edge sanding method. Use extreme caution when preparing for your initial test run. Always keep one finger on the STOP button in order to quickly shut off the machine in the event of a malfunction. DO NOT attempt to investigate or adjust the machine while the machine is still running. Turn off the machine and disconnect it from its power source before attempting any repair or adjustment. Serious operator injury could occur if this guideline is not followed. Figure 27 depicts a typical method for sanding the end of a workpiece. Figure 27. Typical end grain sanding method. -18-G1140 Edge Sander Horizontal Sanding When face sanding, tilt the platen so it is horizontal and use the back stop to hold your work- piece. Apply even hand pressure while moving the workpiece back and forth for even belt wear. Contour Sanding When contour sanding, adjust the auxiliary table up or down so the workpiece is roughly centered on the roller. Move the workpiece over the roller to achieve your desired profile. Figure 28. Typical face sanding method. Figure 29. Typical contour sanding method. Sanding surfaces are capable of causing serious personal injury if they come in contact with fingers, hands or other body parts. Use extreme care to provide a large buffer area between the sanding belt and any part of your body. Do not operate this equipment when wearing loose clothing, gloves, neckties, rings, bracelets or other jewelry which might get caught in the moving belt or trapped between the belt and the tables. Serious personal injury may result. G1140 Edge Sander -19 SECTION 7: MAINTENANCE General Make a habit of inspecting your sander each time you use it. Check for the following conditions and repair or replace when necessary. 1. Loose mounting bolts. 2. Worn switch. 3. Worn or damaged cords and plugs. 4. Damaged sanding belt. 5. Any other condition that could hamper the safe operation of this machine. Lubrication Shielded and pre-lubricated ball bearings require no lubrication for the life of the bearings. In a continuous- use environment, expect the bearings to last for several years. With intermittent use, bearings can be expected to last much longer. All bearings are standard sizes and can be easily replaced. Table The table and other non-painted surfaces on the Model G1140 should be protected against rust and pitting. Wiping the sander clean after every use ensures that moisture from sander dust isn’t allowed to trap moisture against bare metal surfaces. Some woodworkers recommend using automotive paste wax on exposed steel and cast iron surfaces. The wax provides a layer of protection, as well a...
