SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating this Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions for Machinery 7. ONLY ALLOW TRAINED AND PROPERLY SUPERVISED PERSONNEL TO OPERATE MACHINERY. Make sure operation instructions are safe and clearly understood. 8. KEEP CHILDREN AND VISITORS AWAY. Keep all children and visitors a safe distance from the work area. 9. MAKE WORKSHOP CHILD PROOF. Use padlocks, master switches, and remove start switch keys. 10. NEVER LEAVE WHEN MACHINE IS RUNNING.
Additional Safety for Drum Sanders 1. 2. FEEDING STOCK. DO NOT allow anyone to stand at the outfeed end when feeding your stock. Never sand more than one piece of stock at a time. 6. DUST COLLECTION SYSTEM. Never operate the sander without an adequate dust collection system in place and running. DO NOT jam the workpiece into the machine during operation. Firmly grasp the workpiece in both hands and ease it into the machine using light pressure. 7. BE ATTENTIVE.
SECTION 2: CIRCUIT REQUIREMENTS G0449 G0450 at 220V Serious personal injury could occur if you connect the machine to the power source before you have completed the set up process. DO NOT connect the machine to the power source until instructed to do so. Serious personal injury could occur if you connect your machine to the power source before you have completed the set up process. DO NOT connect the machine to the power source until instructed to do so.
G0450 at 440V Serious personal injury could occur if you connect your machine to the power source before you have completed the set up process. DO NOT connect the machine to the power source until instructed to do so. Power Connection Because of the high amperage draw from this machine, we recommend that you hardwire it directly to your circuit breaker and install a locking shut-off lever (see Figure 3) near the machine as a way to quickly disconnect the power and prevent accidental starting.
Grounding Rewiring to 440V In the event of an electrical short, grounding reduces the risk of electric shock. The grounding wire in the power cord must be properly connected to the grounding prong on the plug; likewise, the outlet must be properly installed and grounded. All electrical connections must be made in accordance with local codes and ordinances. The Model G0450 can be rewired for 440V operation.
SECTION 3: SET UP Set Up Safety This machine presents serious injury hazards to untrained users. Read through this entire manual to become familiar with the controls and operations before starting the machine! Wear safety glasses during the entire set up process!

Placing Sander The Model G0449/G0450 has a shipping weight of 1190/1275 lbs. Serious personal injury may occur if safe moving methods are not followed. To be safe, get assistance and use power equipment when moving the crate and removing the machine from the crate. Mounting to Floor Although not required, we recommend that you mount your new machine to the floor. Because this is an optional step and floor materials may vary, floor mounting hardware is not included.
Installing Handwheel Dust Collection Components and Hardware Needed: Qty Handwheel ........................................................ 1 This drum sander requires a minimum of 1600 CFM at the sander. We recommend using a dust collection system that produces a minimum of 2000 CFM. A fine layer of dust will be present on your stock as it comes out of the sander. This is normal. To mount the handwheel: 1.
Power Cord Before installing the power cord, read through SECTION 2: CIRCUIT REQUIREMENTS to check that your setup follows the safety and circuit requirements, and the power cord and power disconnect that you have chosen meet the requirements for this machine. Components and Hardware Needed: Qty Power Cord (Not Included) .................................1 To connect the sander to the power source: 1. Remove the screws securing the control panel and lift off the face plate. Figure 14.
Test Run Now that the machine is connected to the power source, it is important to perform a test run to make sure all the controls are working properly. Before starting the sander, make sure you have performed the preceding assembly and adjustment instructions, and you have read through the rest of the manual and are familiar with the various functions and safety issues associated with this machine.
SECTION 4: OPERATIONS Operation Safety Depth of Cut 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. The optimum depth of cut will vary based on the type of wood, feed rate, and sandpaper grit. Under most sanding conditions, the depth should not exceed 1⁄ 64" or 0.4mm (approx. 3 ⁄4 turn of the handwheel).
Variable Speed The variable speed knob allows you to increase the feed rate from 6–18 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish you are at 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.
Sanding Tips • Replace the sandpaper with a higher grit to achieve a finer finish. • Raise the table with a maximum of 3 ⁄4 turn of the height handle 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.
Paper Replacement The Model G0449/G0450 is designed for 6" wide sandpaper rolls. Turn to SECTION 5: ACCESSORIES on Page 25 for grit selection and model numbers. 5. Repeat Steps 2–4 on the opposite end of the sanding drum, then remove the spring clips. Note: Replace the paper on each drum individually. Once the paper is removed the drums can be slippery and hard to rotate. 6. Tools Needed: Qty Phillips Screwdriver #2 ..................................... 1 Spring Tension Tools ...........................
SECTION 5: ACCESSORIES Aluminum Oxide Sanding Rolls, 6" x 50' H4776—36 Grit: Use for rough sawn boards, thickness sanding, and glue removal. G2787—60 Grit: Use for thickness sanding and glue removal. H4777—80 Grit: Use for removing planer marks and initial finish sanding. G2788—100 Grit: Use for removing planer marks and initial finish sanding. H4778—120 Grit: Use for finish sanding. G2789—150 Grit: Use for finish sanding.
SECTION 6: MAINTENANCE Lubrication Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Moving parts such as chains should be lubricated periodically with a light machine oil. Motor bearings need no lubrication. Use only adequate lubrication.
2. Slide the gearbox out, remove the fill plug (Figure 24), remove the drain plug, drain the oil, and reinstall the drain plug. Worm Gear: Place a dab of lithium grease on the worm gear threads (Figure 26) once a year. Fill Plug Drain Plug Figure 26. Worm gear threads. Figure 24. Lubricating gear box. 3. Add new oil, then reinstall the fill plug. Table Lift Screws: These should be lubricated with lithium grease every six months.

Drum bearings are worn and need 2. Replace the drum bearings. replacement. Short V-belt lifespan. 1. Pulleys not aligned correctly. 2. Improperly tensioned. 1. Align pulleys (Page 31). 2. Properly tension V-belts (Page 30). Machine lacks power; drums stop turning 1. V-belts loose. 1.
Gauge Blocks V-Belt Service Tools Needed: Qty 6' Long 2x4 ........................................................ 1 Miter Saw (or Circular Saw) .............................. 1 Jointer ................................................................ 1 Table Saw ......................................................... 1 Tools Needed: Qty Hex Wrench 5mm.............................................. 1 Wrench 19mm ................................................... 2 Straightedge (at least 24")............
Pulley Alignment To adjust V-belt tension: 1. Disconnect power to the sander! 2. Open the side cover. 3. Turn the motor mount nuts in the direction shown in Figure 30 to loosen or tighten the V-belts. 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.
Conveyor Tensioning & Tracking 3. —If the conveyor starts tracking to one side, immediately turn the drum sander OFF and perform the tracking instructions. Tools Needed: Qty Wrench 19mm ................................................... 1 4. Tensioning The conveyor may slightly stretch with continued use and will eventually need to be tensioned. This is most obvious if the conveyor starts slipping on the rollers.
Drum Adjustments The drums can be adjusted in fine increments at the pillow bearings and in larger increments by using the table lift screws (Page 27). Tools Needed: Qty Hex Wrench 5mm.............................................. 1 Hex Wrench 4mm.............................................. 1 Wrench 19mm ................................................... 1 Wrench 10mm ................................................... 1 Wrenches/Sockets 14mm ................................. 2 Measuring Tape .........
5. Place the gauge blocks on the conveyor table and position them under the drum rollers, as shown in Figure 36. 10. Adjust the height of the drum ends by loosening the locknuts and sliding the pillow bearing up or down along the wedge. —If you need more room behind the drum, adjust the dust scoop as described in Dust Scoop Position on Page 37. —If you need to move the drum up or down more than can be done at the pillow bearing, then you need to adjust the table lift screw in that corner.
13. Tighten all the lock nuts. 14. Check the height of the drum ends to make sure they did not move. —If they did not move, continue to the next step. —If they did move, repeat Steps 11-12. 15. Raise the table up until the gauge blocks just touch the rear drum, as described in Step 7. 16.
Pressure Roller Height Note: An additional trick for eliminating snipe is to reduce pressure on the rear rollers, but not the front rollers. Conditions will vary with wood types, so use trial-and-error to find the best results for your application. Tools Needed: Qty Hex Wrench 4mm.............................................. 1 Wrenches/Sockets 14mm ................................. 2 Gauge Blocks (see Page 30) ............................
