Keep loose clothing rolled up and long hair tied up and away from machinery. Table Movement Adjusting Feed Rate T able height can be adjusted manually or with the digital key pad and motor (see Figure 15). Manual Table Movement: Turn the handwheel located under the front of the infeed table for manual table positioning. Motorized Table Movement: Press the TABLE UP or TABLE DOWN key once for motorized table positioning in 0.005" (0.1mm) increments. Numerical Key Pad: Push the keys to enter the sanding depth needed. Metric or Standard Key: Press and hold the SET button for 3 seconds to calibrate display at the current board thickness; or press and hold key for 10 seconds to toggle the display between metric and standard measurement. Table Start Key: Push to move table to a preset sanding depth. Table Stop Key: Push to stop the table movement immediately. Digital Display: Shows final table sanding depth. Metric or Standard Key Table Start The dial attached to the side of the feed belt gear box (Figure 16) adjusts the feed rate of the sander. Note: Never adjust the feed rate dial unless the conveyor belt is running, otherwise you can damage the control. Changing Feed Rate: Turn the dial clockwise to decrease the feed rate and counterclockwise to increase it. Determining Ideal Feed Rates: Softwoods typically require a faster feed rate than hardwoods; however, there is no definitive rule to follow when determining the best feed rate. As a general rule, always start with the slowest feed rate and work your way up. We always recommend testing the feed rate using scrap wood similar to your workpiece. Be sure to monitor the amperage meter when adjusting the feed rate. Decrease the feed rate if the load amperage level shown on the load meter is enters the yellow zone or sanding RPM begins to slow. Figure 15. Keys for adjusting the table height. Figure 16. Feed rate dial. NOTICE The thickness gauge is pre-calibrated from the factory; however, correct calibration should be verified. -22- G0445/G0582/G9962Z/9962ZX Wide Belt Sander Amp Draw Meter The amperage draw meter (Figure 17) is located above the control panel. Use the meter to monitor the amperage draw on the machine while performing sanding operations. As a general rule, always start with a small load and work your way up. DO NOT work your machine to its maximum load, where you can hear the motor lose RPM; instead, make multiple passes or install a coarser grit paper. Amp load will be directly affected by many factors such as feed rate, depth of cut, wood type, sandpaper grit, and workpiece width. If the amp load is in the red load range, the machine is overloaded and motor damage will occur. Keep the amp load in the green range during operation. NOTICE DO NOT VOID WARRANTY! Keep the amp draw within the GREEN load range shown on the AMP LOAD CHART. If you operate the sander in the RED load range, capacitor or motor failure will occur and will not be covered under warranty. Figure 17. Typical amp draw meter and load chart. G0445/G0582/G9962Z/9962ZX Wide Belt Sander mm w -23- Sanding Workpiece Platen Adjustment Typically, no more than 0.5mm (approx. V64") of material is removed during each pass. Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish, short motor life. Make sure that you measure the workpiece thickness before and after every pass. The following is the correct sanding operating procedure: 1. Put on safety glasses, a dust mask, and hearing protection! 2. Turn ON the dust collector. 3. On the initial pass, set the table so the sandpaper is 0.25" above the workpiece. Note: This initial pass setting eliminates the chance of overloading the sander on undetected high points on the workpiece. 4. Continue to raise the table 0.0625" between each successive pass until the sander begins to sand the workpiece. Your sander is equipped with an adjustable felt platen and graphite pad for those extra sensitive sanding operations. The platen position allows for 3 basic types of sanding. These different positions can be adjusted by rotating the height lever shown in Figure 18. Figure 18. Platen height controls. Using the platen: For an initial heavy-sanding pass, the platen is raised above the level of the drums, and the table is adjusted to set sanding depth. The drums do all the work using #100 grit or coarser sandpaper, but you will have a rough finish. For an intermediate-finishing pass, the platen is lowered so it is level with the drums, and the table is adjusted to set sanding depth. The best belt grit for this position is #100-#180. For a final-sanding pass, do not adjust the table to adjust the sanding depth. The drums must touch the workpiece without doing any sanding. The platen should be lowered to 0.2 to 0.5 mm below the sanding drums. You can lower the platen up to 2 mm below the drums for short intervals, but streaking, burn marks, and premature graphi...
