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 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.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to avoid accidentalslips,whichcouldcauselossofworkpiececontrol. hAzARdOus dusT. Dust created while using machinery may cause cancer, birth defects, or long-term respiratory damage.
Additional Safety for Drum Sanders FEEDING STOCK. Do not stand in the direct path of a workpiece at the infeed end when feeding your stock. Never sand more than one piece of stock at a time. 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. MINIMUM STOCK DIMENSIONS. Do not sand any stock thinner than 1⁄ 8", narrower than 2", or shorter than 8".
SECTION 2: POWER SUPPLY Availability Circuit Requirements Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrican or qualified service personnel in accordance with all applicable codes and standards.
Grounding & Plug Requirements This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current. This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (similar to the figure below). The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.
SECTION 3: SETUP Unpacking to reduce your risk of serious injury, read this entire manual bEfORE using machine. Wear safety glasses during the entire setup process! Your machine was carefully packaged for safe transportation. Remove the packaging materials from around your machine and inspect it. If you discover any damage, please call us immediately at (570) 546-9663 for advice. Save the containers and all packing materials for possible inspection by the carrier or its agent.
Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Mounting The base of this machine has holes that allow it to be mounted to a workbench. We strongly recommend that you mount your machine to a workbench to prevent it from moving during operation. An unexpected movement could result in an injury or property damage. The strongest mounting option is a "Through Mount" where holes are drilled all the way through the workbench, and hex bolts, washers, and hex nuts are used to secure the drum sander to the workbench.
Dust Collection DO NOT operate the Model G0459/G0459P without an adequate dust collection system. This sander creates substantial amounts of wood dust while operating. Failure to use a dust collection system can result in short and long-term respiratory illness. Recommended CFM at Dust Port: 150 CFM Do not confuse this CFM recommendation with the rating of the dust collector.
Test Run Recommended Adjustments Once the assembly is complete, test run your machine to make sure it runs properly. If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review the Troubleshooting on Manual Page 23. If you still cannot remedy a problem, contact our Tech Support at (570) 546-9663 for assistance.
SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide.
Basic Controls Refer to Figure 11 and the following descriptions to become familiar with the basic controls of this machine. A. Variable Speed Knob: Adjusts feed rate from 2.47–17.3 FPM. Rotate clockwise to increase feed speed, rotate counterclockwise to decrease feed speed. B. Hand Crank: Used to raise or lower the conveyor table to control depth of cut. Each full rotation of the hand crank raises or lowers the conveyor table approximately 0.027" (0.69 mm).
Sanding Tips • Replace the sandpaper with a higher grit to achieve a finer finish. • Raise the table with a maximum of ⁄4 turn of the crank handle until the workpiece is the desired thickness. 1 Stock Inspection and Requirements Some workpieces are not safe or may require modification before they are safe to sand.
Depth of Cut 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 0.006" (0.15 mm) (approx. 1⁄4 turn of the handwheel). Each full turn of the crank handle raises the conveyor table approximately 0.027" (0.69 mm). Attempts to remove too much material can cause jamming, wood burning, rapid paper wear or tearing, poor finish, belt slippage, and motor damage. To set the depth of cut: 1.
Variable Speed The variable speed knob allows you to increase the feed rate from 2.47–17.3 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 sands the surface smoother, but runs the risk of burning the wood; a faster feed rate removes material faster, but runs the risk of overloading the motor.
Choosing Sandpaper There are many types of sanding belts to choose from. We recommend aluminum oxide for general workshop environments. Below is a chart that groups abrasives into different classes, and shows which grits fall into each class. Grit Class 36 Extra Coarse Rough sawn boards, thickness sanding, and glue removal. 12 3/4" Usage 60 Coarse Thickness sanding and glue removal. 80–100 Medium planer Removing marks and initial finish sanding. 120–180 Fine 4.
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. NOTICE Refer to the newest copy of the Grizzly Catalog for other accessories available for this machine. Aluminum Oxide Hook & Loop Sanding Rolls, 3" x 50' H4422—60 Grit: Use for thickness sanding and glue removal.
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. Daily Check: • Loose mounting bolts. Worn switch. • • Worn or damaged cords or plugs. • Damaged V-belt. • Any other unsafe condition.
Pillow Block Bearings These must be lubricated every 20 hours of operation. Use a grease gun to pump one or two shots of a high-quality grease into each grease fitting (Figure 22), located on the top of each pillow block bearing. Failure to routinely inspect your drum sander for damage and wear could result in unsatisfactory work results, premature component or machinery failure, or operator injury. We recommend you create a checklist for routine inspection and maintenance.
