Dust Collection DO NOT operate the Model G0458 without adequate dust collection. This sander creates substantial amounts of wood dust while operating. Failure to use dust collection can result in short and long-term respiratory illness. You may attach the Model G0458 drum sander to a dust collection system if you do not use the included dust bag. If you are using your own dust collection system, we recommend using a system that can collect a minimum of 400 CFM AT THE DUST PORT.
Recommended Adjustments For your convenience, the adjustments listed below have been performed at the factory and no further setup is required to operate your machine. However, because of the many variables involved with shipping, some of these adjustments may need to be repeated to ensure optimum results. Keep this in mind as you start to use your new drum sander. Step-by-step instructions for these adjustments can be found in SECTION 7: SERVICE ADJUSTMENTS. 1. V-Belt Tensioning (Page 27).
SECTION 4: OPERATIONS Operation Safety Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine. Depth of Cut The optimum depth of cut will vary based on the type of wood, feed rate, and sandpaper grit. Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish, and belt slippage. To set the depth of cut: 1.
Variable Speed The variable speed knob allows you to increase the feed rate from 2–12 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish with that workpiece. As a general rule, a slower feed rate will sand the surface smoother, but runs the risk of burning the wood; a faster feed rate will remove material faster, but runs the risk of overloading the motor or damaging the sandpaper.
Sanding Tips • Replace the sandpaper with a higher grit to achieve a finer finish. • Raise the table a maximum of 1⁄4 turn of the handwheel until the workpiece is the desired thickness. • Reduce snipe when sanding more than one board of the same thickness by feeding them into the sander with the front end of the second board touching the back end of the first board. Choosing Sandpaper There are many types of sanding belts to choose from. We recommend Aluminum Oxide for general workshop environments.
Paper Replacement Tools Needed: Qty Flat Head Screwdriver ...................................... 1 Hex Wrench 4mm .............................................. 1 Hex Wrench 5mm .............................................. 1 Carton Cutter or Utility Knife ............................. 1 6. Loosen the cap screw on the left clamp and remove the sandpaper. 7. Use the old sandpaper as a pattern, or use the pattern in Figure 19, to cut a new piece of sandpaper to the necessary shape.
9. Wrap the sandpaper around the drum (Figure 21), ensuring there are no bubbles or overlapping edges. Figure 21. Wrapping sandpaper around drum. 10. When the sandpaper reaches the right side of the drum, move the sandpaper out of the way with a 4mm wrench and place it into the access hole. 11. Rotate the drum toward you so the wrench rests against the frame as shown in Figure 22. 12.

SECTION 6: MAINTENANCE Cleaning Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule For safe and optimum performance from a machine that is used on a daily basis, follow this maintenance schedule and refer to any specific instructions given in this section. Daily Checks and Maintenance: • Loose mounting bolts. • Damaged sanding belt. • Worn switch. • Worn or damaged cords or plugs. • Damaged V-belts.
Feed Belt Drive: Lubricate with lithium grease monthly. Wipe sawdust and dirt impregnated grease off of the chain and gears shown in Figures 28 & 29. Apply fresh lithium grease to the gears and chain. Table Lift Mechanism: Lubricate the table lift screws, chain, and helical gear with lithium grease every six months. Clean the chain and table lift screws (Figure 30), then rub lithium grease onto the chain links and screw threads. Clean the helical gear (Figure 31) and place a dab of grease on the teeth.
V-Belt Tensioning 3. Tools Needed: Qty Hex Wrenches 4 & 8mm ..............................1 Ea Phillips Head Screwdriver ................................. 1 Pry Bar .............................................................. 1 Check the tension of the feed belt V-belt, then adjust the tension by loosening the motor mount cap screws shown in Figure 33 and pushing down on the motor mount to tighten the V-belts.

SECTION 7: SERVICE This section is provided for your convenience—it is not a substitute for the Grizzly Service Department. If you need help troubleshooting, you need replacement parts, or you are unsure of how to perform the procedures in this section, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Motor & Electrical Symptom Possible Cause Machine does not start or 1. a breaker trips. 2. 3. 4. 5. 6. 7. 8. 9. 1.
Symptom Possible Cause Machine has vibration or 1. Motor or component is loose. noisy operation. 2. V-belts are worn or loose. 3. Motor fan is rubbing on fan cover. 4. Pulley is loose. 5. Machine is incorrectly mounted to the floor. 6. Cast iron motor mount is at fault. 7. Motor bearings are at fault. Possible Solution 1. Inspect for stripped/damaged bolts/nuts, replace/re-tighten with thread locking fluid. 2. Inspect belts, replace and re-tension (see Pages 27 & 30). 3.
Replacing V-Belts Tools Needed: Qty Hex Wrenches 4, 6 & 8mm ..........................1 Ea Phillips Head Screwdriver ................................. 1 Pry Bar .............................................................. 1 Inspect the V-belts closely; if you notice fraying, cracking, glazing, or any other damage, replace the belts. A worn/damaged V-belt will not provide optimum power transmission from the motor to the drum and feed belt. 4.
Pulley Alignment Tools Needed: Qty Hex Wrenches 4 & 8mm ..............................1 Ea Phillips Head Screwdriver ................................. 1 Pry Bar .............................................................. 1 Pulley alignment is another important factor in power transmission and belt life. The pulleys should be parallel to each other and in the same plane (coplaner) for optimum performance.
2. Loosen the lock nut (Figure 38) on the side that the feed belt tracks towards and tension the tracking adjustment screw until the feed belt tracks in the opposite direction. To tension the feed belt: 1. Note: Small tracking changes may take up to three minutes before they are noticeable. Lock Nut Tracking Adjustment Screw Figure 38. Feed belt tracking adjustment bolt. 3.
Feed Belt Replacement Tools Needed: Qty Wrench 12mm ................................................... 2 Hex Wrench 6mm.............................................. 1 An Assistant ...................................................... 1 Replacing the feed belt is a simple process, but will require tensioning and tracking when completed. 5. Have an assistant lift the outside edge of the table, then slide the feed belt off. 6.
Gauge Blocks Table Adjustments Tools Needed: Qty 6' Long 2x4 ........................................................ 1 Miter Saw (or Circular Saw) .............................. 1 Jointer ................................................................ 1 Table Saw ......................................................... 1 Aligning the drums parallel to the conveyor belt (Figure 43) is critical for sanding accuracy. Care should be taken to make the tolerances as close as possible (within 0.
3. Note: A good way to know when they are touching is to rock the drum back and forth while raising the table until you hear or feel contact with the gauge blocks. 4. 5. 6. Lower the table one full crank of the handwheel (taking handwheel free-play into consideration; or in other words, wait until the chain starts moving before starting to count the handwheel rotation). Starting at one end, find the largest size feeler gauge that can pass between the drum and your gauge block.
5. Raise the table until the gauge blocks just touch the drum. 6. Find the largest size feeler gauge that can pass between the front pressure plate and your gauge block. (The feeler gauge should slide with moderate resistance, without forcing the drum to roll.) —If the gap is 0.004" (0.1mm) or less, then no adjustment of the front pressure plate is necessary. —If the gap is more than 0.004" (0.1mm), then the front pressure plate must be adjusted. To adjust the rear pressure plate: 1.
