SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment 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 Power Tools 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.
Additional Safety Instructions For Sanders 1. BE AWARE OF BELT or disc rotation when sanding. 2. KEEP FINGERTIPS AWAY from the moving belt or disc. Serious injury could result if skin contacts abrasives or moving parts. 3. NEVER USE EXCESSIVE FORCE when sanding. Doing this greatly increases the chances of personal injury and motor overload. 4. ALWAYS FEED THE WORK against the direction of rotation. 5.
SECTION 2: CIRCUIT REQUIREMENTS 110V Operation Grounding The Model G3105 is wired for 110/120V, single phase operation only. The 1⁄2 HP motor will safely draw 3 amps at 110V. If you operate this sander on any circuit that is already close to its capacity, it might blow a fuse or trip a circuit breaker. However, if an unusual load does not exist and a power failure still occurs, contact a qualified electrician or our service department.
SECTION 3: INTRODUCTION Commentary We are proud to offer the Grizzly Model G3105 Combination Belt and Disc Sander. The Model G3105 is part of a growing Grizzly family of fine woodworking machinery. When used according to the guidelines set forth in this manual, you can expect years of trouble-free, enjoyable operation and proof of Grizzly’s commitment to customer satisfaction. The Model G3105 is a combination 1" x 42" belt and 6" disc sander that is capable of a wide variety of operations.
Unpacking Parts Inventory This Combination Sander is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you’ve signed for delivery, and the truck and driver are gone, you will need to file a freight claim with the carrier. Save the containers and all packing materials for possible inspection by the carrier or its agent. Without the packing materials, filing a freight claim can be difficult.
Clean Up Unpainted machine surfaces may be coated with a waxy oil to protect it from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser. Avoid chlorine-based solvents as they may damage painted surfaces should they come in contact. Always follow the usage instructions on the product you choose for clean up. Many of the solvents commonly used to clean machinery can be highly flammable, and toxic when inhaled or ingested.
SECTION 4: ASSEMBLY Overview Most of your G3105 Belt and Disc Sander has been assembled at the factory. The few pieces that remain should go together quickly and easily. Only a few common tools are required to assemble your Combination Sander. Specifically, these are: 12mm open end wrench, Phillips® head screwdriver, 8mm Allen® wrench (provided with machine).
Outside Belt Guard Belt Table Using two of the knobs provided, mount the outside belt guard to the cast-iron, inner belt guard. See Figure 3. Use the 3/8" - 16 x 3/4" cap screw and 3/8" washer to secure the table to the inner belt guard. The slotted bracket is provided to enable maximum adjustment. See Figure 4. Use a machinist’s square to set the table to 90˚ to the face of the sanding belt. The table can also be tilted down an additional 45˚. Simply loosen the cap screw and adjust to the desired angle.
Disc Table Bracket The disc table bracket mounts to the left side of the sanding unit, below the disc. Use the two hex bolts and washers provided. Tighten securely. See Figure 5. Disc Table 1. Unscrew the table trunnion guide screws from the disc table bracket. 2. Mount the disc table to the bracket with two of the knobs and washers provided. 3. Reinstall the table trunnion guide screws into the disc table bracket so that they fit into the slots in the table trunnions. 4.
SECTION 5: Adjustments 3. With the machine running, adjust the tracking so the belt stays on the middle of the wheel. A B 4. Turn off the machine. 5. While holding the adjusting bolt in the proper position, tighten the locknut without changing the adjustment. C Figure 7. Adjustments for tension and tracking. Belt Tension Belt tension is controlled by a spring loaded cam shaft. Push the Belt Tensioning Lever (part C, Figure 8) rearward to slacken the belt.
SECTION 6: Operations Test-Run General Sanding Before you put your Combination Sander into use, give it a quick inspection. Before inspecting, ensure that the machine is switched off and disconnected from its power source. For general wood sanding, position and secure table, turn the machine on, and slowly feed your workpiece into the belt or disc. For disc sanding, note the direction of the disc’s rotation and be sure to feed your workpiece into the disc’s downward spin.
Disc Sanding Disc sanding is well suited for finishing small flat surfaces and curved edges. The down (right) side of the disc is the working area. The disc moves fastest and removes the most material at the outer edge. A miter gauge that fits in the slot in the table is provided. Use it to secure the workpiece and to hold the proper angle when disc sanding. See Figure 10. NOTICE When grinding or polishing metal, the use of a metal abrasive is recommended.
SECTION 7: MAINTENANCE General Belts and Discs Make a habit of inspecting your sander each time you use it. Check for the following conditions and repair or replace when necessary. The Sanding Disc accepts 6" diameter cloth or paper backed sanding discs. The belt sander requires a 1" x 42" sanding belt. For disc or belt sanding, we recommend a 100 grit (medium) material for general purpose sanding, a 60 grit (coarse) material for rough work, and a 150 grit (fine) material for finish jobs. 1.
