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.
DISCONNECTING POWER SUPPLY.Alwaysdisconnect machine from power supply before servicing, adjusting, or changing cutting tools (bits, blades, cutters, etc.). Make sure switch is in OFF positionbeforereconnectingtoavoidanunexpectedorunintentionalstart. APPROVED OPERATION. Untrained operators can be seriously hurt by machinery. Only allow trained or properly supervised people to use machine.
Additional Safety for Combination Sanders DISC DIRECTION. Only sand on the downwardmoving left side of the sanding disc. Sanding on the upward-moving right side of the sanding disc forces the operator to rely only on hands (rather than the table) for support, which increases the risk of workpiece "kick-out" and impact/abrasion injuries. WORKPIECE INSPECTION.
SECTION 2: POWER SUPPLY Availability Circuit Information 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 a qualified electrician in accordance with all applicable codes and standards.
Grounding 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. For 110V operation: This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (see following figure).
Extension Cords We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis. Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).
SECTION 3: SETUP Needed for Setup 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 setup process! This machine and its components are very heavy. Get lifting help or use power lifting equipment such as a forklift to move heavy items.
Inventory The following is a description of the main components shipped with your machine. Lay the components out to inventory them. A B C If any non-proprietary parts are missing (e.g. a nut or a washer), we will gladly replace them; or for the sake of expediency, replacements can be obtained at your local hardware store. D E G Shipping Inventory: (Figure 8) Qty A. Sander Assembly........................................1 B. Sanding Belt Table......................................1 C.
Cleanup The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.
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 accept 5 ⁄ 8" bolts for mounting the machine 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. Assembly To assemble the sander: 1. Unthread the screw cap on the sanding belt table lock lever, remove the lever, then unthread the lock bolt and flat washer from the sander (see Figure 12).
4. Attach the sanding belt table to the trunnion by finger tightening the (3) 5⁄16"-11 x 1" hex bolts and 5⁄16" flat washers from underneath the table, as shown in Figure 14. The hex bolts will be fully tightened when aligning the tables in later steps. 6. Loosen the sanding belt pivot cap screw shown in Figure 16, rotate the sanding belt assembly to the vertical position, then retighten the cap screw to hold it place. x3 Pivot Cap Screw Figure 14. Sanding belt table installed. 5.
Table Gap Adjustment 8. Loosen the sanding disc table lock knobs, then move the trunnion brackets away from the lower disc guard, as shown in Figure 18. Trunnion Bracket (1 of 2) To reduce the risk of in-running nip (pinch) points, yet avoid the risk of the sandpaper contacting the tables, the tables should be adjusted away from the sandpaper no more than 1⁄ 16". Note: The procedure for the table gap adjustment is similar for both tables. To adjust the table-to-sandpaper gap: Lock Knob Figure 18.
3. Loosen the hex bolts underneath the table that secure it to the trunnion(s). Note: The sanding belt table has three hex bolts (see Figure 21), and the sanding disc table has two hex bolts on both sides of the table (see Figure 22). Checking Belt Tracking Proper belt tracking depends on two conditions: 1) The platen height, and 2) the upper roller parallelism.
Dust Collection To connect the sander to the dust collection system: 1. DO NOT operate the Model G1183/G1276 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: 3" Dust Port................................. 220 CFM 2 1⁄ 2" Dust Hose............................
Power Connection Test Run After you have completed all previous setup instructions and circuit requirements, the machine is ready to be connected to the power supply. Once the assembly is complete, test run your machine to make sure it runs properly. To avoid unexpected startups or property damage, use the following steps whenever connecting or disconnecting the machine. Connecting Power 1. Turn the machine power switch OFF. 2. Insert the power cord plug into a matching power supply receptacle.
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.
Table Tilt Angle sanding is performed with the table tilted away from 0° (perpendicular to the sanding surface). Compound angles are sanded using a combination of table tilt and miter gauge angle. Table Tilt Ranges Sanding Belt Table........................... -45° to +45° Sanding Disc Table.......................... -40° to +30° Both tables have an adjustable positive stop that is used to quickly return the table to 0°. The belt table has an additional stop at -45° and uses a flip stop to engage the stops.
Sandpaper Selection Sanding a workpiece smooth requires using progressively smaller grit sandpaper until the desired finish is attained. The abrasiveness of sandpaper is designated in grit size—the larger the number, the finer the abrasive and the smaller the scratches. Thus, 100 grit is finer than 60 grit. Typically, sanding operations start with a coarse grit and progressively work through the finer (larger number) grits until the desired finish is achieved.
Disc Sandpaper Replacement The Model G1183/G1276 sander ships with a preinstalled 80-grit, 12" diameter adhesive-backed sanding disc. The sanding disc sticks to the surface of the cast iron disc platen, using the pressure-sensitive adhesive (PSA) backing. The sandpaper can be replaced without removing the table or dust port. To replace the disc sandpaper: 1. DISCONNECT SANDER FROM POWER! Disc Sanding Only sand on the downward-moving left side of the sanding disc.
Belt Sanding The sanding belt removes material faster than the sanding disc, and can be secured at any angle from horizontal to completely vertical with the use of the pivot cap screw shown in Figure 36. Figure 34. Example of compound angle sanding. Figure 35. Example of round workpiece sanding. Pivot Cap Screw Figure 36. Positioning the sanding belt assembly.
Always sand with the workpiece supported by the table. Relying only hands to support the workpiece increases the risk of workpiece "kick-out" and impact/abrasion injuries. Refer to Figures 37–40 for examples of sanding operations that are possible with the belt sanding assembly. Figure 39. Example of vertical miter sanding. Figure 37. Sanding workpiece in horizontal position. Figure 40. Examples of vertical face and edge sanding.
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. G2405—Safety Push Blocks Made of high-impact molded plastic, these safety push blocks have a layer of friction rubber on the bottom that grabs your workpiece as you press down.
