Workpiece Inspection Some workpieces are not safe to sand or may require modification before they are safe to sand. Before sanding, inspect all workpieces for the following: • • • • • • Material Type: This machine is intended for sanding natural and man-made wood products. This machine is NOT designed to sand metal, glass, stone, tile, etc.; sanding these materials with a drum sander saw may lead to injury.
Replacement Replacement sandpaper for the Model G0716 is available in 3" bulk rolls (see Page 28 for options from Grizzly). When fabricating a replacement sandpaper strip from bulk rolls, either use the existing strip as a template or refer to the dimensioning information in Figure 17. 3" The proper installation of the sandpaper strip on the drum is essential to ensure good sanding results and prevent the sandpaper from coming loose or tearing during operation. Items Needed Qty Hex Wrench 5mm.............
4. Unwind the sandpaper strip from the drum until you reach the clamping device on the left side (see Figure 19). 8. While keeping reasonable tension on the strip with one hand, roll the drum away from you with the other hand to wrap the strip onto the drum (see Figure 20). Important: When wrapping the strip onto the drum, a minimum 1⁄8" gap between the edges may be necessary, but do not overlap. Additionally, make sure that the strip remains tight without any slack. Clamping Device Figure 19.
10. Press the spring lever toward the clamp to open it, then fully insert the end of the sandpaper strip between the two sides of the clamp, as shown in Figure 22. Removing Pin Important. Make sure that the sandpaper end goes inside the clamp—not between the spring lever and the clamp. Spring Lever Released Maintaining Pressure on Clamp Figure 23. Properly securing the sandpaper end. The sandpaper goes here. Figure 22. Inserting the sandpaper end between the two sides of the clamp. 11.
Depth of Cut To adjust the depth of cut: 1. The correct depth of cut when surface sanding with the Model G0716 depends on many variables, such as the hardness of the wood, the width of the workpiece, and the feed rate. Handwheel Generally, a 1⁄4 turn of the elevation handwheel (1⁄ 32" depth of cut) per pass is acceptable for coarser grits or softer woods. A 1⁄ 8 turn of the handwheel (1⁄ 64" depth of cut) is recommended for finer grits or harder woods.
Feed Rate Sanding Tips Setting the proper feed rate is a matter of experience and good judgement. When selecting the feed rate for the operation, consider variables such as the hardness and condition of the wood, the sandpaper grit being used, the finish desired, etc. Follow these precautions to ensure safe sanding operation and quality results: • Replace the sandpaper with a higher grit to achieve a finer finish (refer to Sandpaper on Page 21).
Sanding Operation 8. When the sanding drum has complete control of the workpiece, step to the rear of the sander, and maintain control and support of the workpiece as it leaves the sanding drum on its own. 9. Without changing the depth-of-cut setting, rotate the workpiece 180° horizontally and pass it through the sander again. To surface sand a workpiece: 1. Make sure the sander is turned OFF and the sanding drum is completely stopped. 2.
ACCESSORIES SECTION 5: ACCESSORIES Some aftermarket accessories can be installed on this machine that could cause it to function improperly, increasing the risk of serious personal injury. To minimize this risk, only install accessories recommended for this machine by Grizzly. 3" x 10 ft.

Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily Check • Loose mounting bolts. • Damaged, worn, or loaded sandpaper. • Worn or damaged wires or switches. Worn or damaged conveyor belt. • Any other unsafe condition.
SECTION 7: SERVICE Review the troubleshooting and procedures in this section to fix or adjust your machine if a problem develops. If you need replacement parts or you are unsure of your repair skills, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Symptom Possible Cause Possible Solution Machine does not start or a breaker trips. 1. Switch disabling key removed. 2. Power source switched OFF or at fault. 1. Re-install switch disabling key. 2.
Symptom Possible Cause Possible Solution Sandpaper clogs quickly. 1. Sanding depth of cut too much or feed rate too slow. 2. Workpiece has high moisture content or sap. 5. Sandpaper loaded with sawdust and gum. 1. Reduce depth of cut or increase feed rate; use coarser grit sandpaper. 2. Use different stock, or accept the characteristics of the stock and plan on cleaning/replacing sandpaper frequently; remove applied finishes before sanding. 3.
Symptom Possible Cause Possible Solution Ripples or lines in workpiece. 1. Uneven feed rate. 1. Maintain an even feed rate through the entire sanding operation. 2. Make sure the elevation lock knob is tight. 2. Sanding drum deflecting from workpiece. Snipe marks in workpiece. -32- 1. Improper pressure roller tension. 2. Workpiece too long to be supported without additional help. 1. Evenly adjust pressure roller tension (see Page 36). 2.
Conveyor Belt Tension & Tracking 3. As a starting point, make sure that the ends of both tensioning screws extend evenly approximately 1⁄4" beyond the hex nut, as shown in Figure 31. —If the belt slips during operation, rotate the screws clockwise in small amounts until the belt no longer slips on the rollers.
Gib Adjustment If the gibs are too loose, the sanding drum will deflect up during operation, which will result in poor sanding results. The gibs apply pressure to the slides of the sanding head (see Figures 32–33). This allows the sanding head assembly to accurately move up and down when using the elevation handwheel. If the gibs are too tight, it will be difficult to adjust the sanding drum elevation, which will cause excessive wear on the parts of the elevation system. To adjust the gibs: Slide 1.
Conveyor Belt to Drum Alignment 3. Take several light cuts through the sander without rotating or flipping the board. 4. Make measurements at "A" and "B" as indicated in Figure 34. To ensure good sanding results, the conveyor belt and sanding drum must be parallel with each other from side to side (see the illustration in Figure 34). Otherwise, more material will be removed from one side of the workpiece than the other.
Pressure Roller Adjustment The height of the pressure rollers (see Figure 36) is set slightly below the bottom of the sanding drum to keep the workpiece firmly against the conveyor belt as it passes through the sander, preventing workpiece kickback. Proper pressure on the workpiece helps avoid kickback and keeps the workpiece from slipping. However, as pressure increases on the workpiece from the rear pressure roller, snipe also increases. In this case, decrease the pressure on the rear roller.
Adjusting Elevation Stop A Phillips head screw that protrudes through the bottom of the frame acts as a stop to prevent the sanding drum from making contact with the conveyor belt when adjusting the height (see Figure 38). Screw & Hex Nut To adjust the elevation stop screw: 1. Make sure the conveyor belt is properly tensioned (refer to Conveyor Belt Tension & Tracking on Page 33 for detailed instructions). 2. DISCONNECT SANDER FROM POWER! 3. Raise the sanding drum all the way up. 4.
Conveyor Belt Replacement 4. Remove the two cap screws and flat washers from the conveyor support (see Figure 39). 5. Lift the conveyor support up slightly and slip the conveyor belt off, as shown in Figure 40. If the conveyor belt becomes excessively worn or damaged, it can easily be replaced. Contact Grizzly Customer Support at 1-800-523-4777 to obtain a replacement belt (Part No. P0706101).
