Inspect blades for cracks and missing teeth before each use. HAND PLACEMENT. Never position hands or fingers in line with the cut or under bandsaw headstock while lowering or operating. Hands could be cut or crushed. ENTANGLEMENT HAZARDS. Do not operate this saw without blade guard in place. Loose clothing, jewelry, long hair and work gloves can be drawn into working parts. BLADE REPLACEMENT. When replacing blades, disconnect the machine from power, wear gloves to protect hands and safety glasses to protect eyes. WORKPIECE HANDLING. Always properly support workpiece with table, vise, or some type of support fixture. Flag long pieces to avoid a tripping hazard. Never hold the workpiece with your hands during a cut. Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur. -8- UNSTABLE WORKPIECES. Avoid cutting workpieces that cannot be properly supported or clamped in a vise or jig, because they can unexpectedly move while cutting and draw the operator’s hands into the blade causing serious personal injury. Examples are chains, cables, round or oblong-shaped workpieces, and those with internal or built-in moving or rotating parts, etc. FIRE HAZARD. Use EXTREME CAUTION if cutting magnesium. Using the wrong cutting fluid could lead to chip fire and possible explosion. CUTTING FLUID SAFETY. Cutting fluids are poisonous. Always follow manufacturer’s cuttingfluid safety instructions. Pay particular attention to contact, contamination, inhalation, storage and disposal warnings. Spilled cutting fluid invites slipping hazards. HOT SURFACES. Contact with hot surfaces from machine components, ejections of hot chips, swarf, and the workpiece itself can cause burns. No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work results. Model G0622 (Mfd. Since 09/17) SECTION 2: POWER SUPPLY Availability 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 electrician or qualified service personnel in accordance with all applicable codes and standards. Electrocution, fire, shock, or equipment damage may occur if machine is not properly grounded and connected to power supply. Full-Load Current Rating The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations. Full-Load Current Rating at 110V......... 5 Amps The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating. If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements. Model G0622 (Mfd. Since 09/17) Serious injury could occur if you connect machine to power before completing setup process. DO NOT connect to power until instructed later in this manual. 110V Circuit Requirements This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements: Nominal Voltage............................... 110V–120V Cycle...........................................................60 Hz Phase............................................ Single-Phase Power Supply Circuit.......................... 15 Amps A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.) For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or electrical codes in your area. Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation. -9- 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. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug! GROUNDED 5-15 RECEPTACLE Grounding Prong 5-15 PLUG Neutral Hot Figure 2. Typical 5-15 plug and receptacle. Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal. Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one. 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 can 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). Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements: Minimum Gauge Size............................14 AWG Maximum Length (Shorter is Better).......50 ft. SHOCK HAZARD! Two-prong outlets do not meet the grounding requirements for this machine. Do not modify or use an adapter on the plug provided—if it will not fit the outlet, have a qualified electrician install the proper outlet with a verified ground. -10- Model G0622 (Mfd.

Since 09/17) 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. There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer’s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes. Before cleaning, gather the following: • Disposable rags • Cleaner/degreaser (WD•40 works well) • Safety glasses & disposable gloves • Plastic paint scraper (optional) Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avo i d u sing t h e s e p r o d u c t s to c l e a n m a c hin e r y. Many cleaning solvents are toxic if inhaled. Only work in a well-ventilated area. NOTICE Avoid chlorine-based solvents, such as acetone or brake parts cleaner, that may damage painted surfaces. T23692—Orange Power Degreaser A great product for removing the waxy shipping grease from your machine during clean up. Basic steps for removing rust preventative: 1. Put on safety glasses. 2. Coat the rust preventative with a liberal amount of cleaner/degreaser, then let it soak for 5–10 minutes. 3. Wipe off the surfaces. If your cleaner/degreaser is effective, the rust preventative will wipe off easily. If you have a plastic paint scraper, scrape off as much as you can first, then wipe off the rest with the rag. 4. Figure 4. T23692 Orange Power Degreaser. Repeat Steps 2–3 as necessary until clean, then coat all unpainted surfaces with a quality metal protectant to prevent rust. Model G0622 (Mfd. Since 09/17) -13- 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. The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20%–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps. Space Allocation Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual. See below for required space allocation. Children or untrained people may be seriously injured by this machine. Only install in an access restricted location. Electrical Installation Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave enough space around machine to disconnect power supply or apply a lockout/tagout device, if required. Lighting Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated. 38" 110V 16" Figure 5. Minimum working clearances. -14- Model G0622 (Mfd. Since 09/17) Assembly 4.

To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses and a respirator when operating this machine. Electrocution Hazard. The motor and switch on this bandsaw are not protected against liquids. Do not use water-based cutting fluids with this bandsaw. If you are not experienced with this type of machine, WE STRONGLY RECOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any projects. Regardless of the content in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training. This overview gives you the basic process that happens during an operation with this machine. Familiarize yourself with this process to better understand the remaining parts of the Operation section. To complete a typical operation, the operator does the following: 1. Prepares the workpiece for cutting. 2. Raises the head. 3. Securely clamps the workpiece in the vise and adjusts the vise angle for the operation. 4. Checks/adjusts the V-belt position on the pulleys to ensure the correct cutting speed for the workpiece. 5. Adjusts the spring tension for the correct feed rate. 6. Makes sure the workpiece and bandsaw are stable and there are no obstructions for the cut. 7. Wears safety glasses. 8. Starts the machine and waits for the blade to reach full speed. 9. Slowly lowers the head until the blade makes contact with the workpiece, then releases the head so that the spring-controlled feed rate continues to lower the blade into the workpiece until the cut is finished. 10. Stops the machine, raises the head, and removes the workpieces. Model G0622 (Mfd. Since 09/17) -19- Operation Tips The following tips will help you safely and effectively operate your bandsaw and help you get the maximum life out of your saw blades. Horizontal Cutting • Use the work stop to quickly and accurately cut multiple pieces of stock to the same length (see Figure 19). • Clamp the material firmly in the vise jaws to ensure a straight cut through the material. • Let the blade reach full speed before engaging the workpiece. Never start a cut with the blade in contact with the workpiece (see Figure 20). • Chips should be curled and silvery. If the chips are thin and powder like, increase your feed rate (refer to the Metal Chip Inspection Chart on Page 27). • If the chips are burned, reduce the blade speed. • Wait until the blade has completely stopped before removing the workpiece from the vise, and avoid touching the cut end—it could be very hot! Figure 19. Work stop. Figure 20. Proper starting position. Vertical Cutting • Workpieces that cannot be properly supported or stabilized without a vise should not be cut in the vertical position. Examples are chains, cables, round or oblong-shaped workpieces, workpieces with internal or builtin moving or rotating parts, etc. • Make sure that the vertical table assembly is securely fastened to the bandsaw frame so it will adequately support the workpiece. • Always keep your fingers away from the blade and always hold the workpiece securely in your hand (Figure 21). • -20- Adjust the blade guides as close as possible to the workpiece to minimize side-to-side blade movement. Figure 21. Using the vertical set-up. NOTICE Loosen blade tension at the end of each day to prolong blade life. Model G0622 (Mfd. Since 09/17) Vertical Operation 5. Place a level on the table, as shown in Figure 24, then use the adjustment bolt shown in Figure 25 to make the table level. The Model G0622 can easily be set up for vertical cutting operations. To assemble the bandsaw for vertical cutting: 1. DISCONNECT BANDSAW FROM POWER! 2. Remove the two flat head screws and the blade guide cover shown in Figure 22. Blade Guide Cover Figure 22. Blade guide cover. 3. Install the table and replace the two screws removed in Step 2. 4.

Head-Locking Pin Install the safety bracket and lock it in place with the pin shown in Figure 26 to keep the saw from falling. Note: To ensure the safety bracket fits securely in the notch on the body frame, the safety bracket may need to be slightly "modified" with a hammer or other appropriate implement to fit securely. Notch The head-locking pin secures the head in the down, horizontal position. You MUST secure the head with the locking pin before moving the machine to prevent the head unexpectedly springing up, causing the machine to tip or fall. Otherwise, serious personal injury or property damage could occur. Safety Bracket Pin The head-locking pin safely secures the head in the down position. To ensure the head does not unexpectedly spring up and tip the bandsaw over, this locking pin must be properly inserted when the bandsaw is not in use or before moving it. To use the head-locking pin: Figure 26. Safety bracket. 1. DISCONNECT BANDSAW FROM POWER! 2. Fully lower the head down, then insert the locking pin through the holes in the head pivot arm and base, as shown in Figure 27. Head-Locking Pin Figure 27. Head-locking pin correctly inserted. 3. -22- Before connecting the machine to power, remove the locking pin. Model G0622 (Mfd. Since 09/17) Vise 3. Use the scale as a guide to set your angle or use a machinist square to set the angle of the vise, as shown in Figure 29. Always turn the saw OFF and allow the blade to come to a complete stop before using the vise! Failure to follow this caution may lead to injury. The vise can hold material up to six inches wide and be set to cut angles from 0° to 60°. Scale Tools Needed Qty Wrench or Socket 12mm.................................... 1 Machinist Square................................................ 1 To use the vise: Figure 29. Squaring vise to blade. 1. DISCONNECT BANDSAW FROM POWER! 4. Tighten the hex bolts. 2. Loosen the two hex bolts shown in Figure 28. 5. Loosen the hex bolt on the opposite jaw so the jaw can float, then match the angle of the workpiece and re-tighten the hex bolt. 6. Tighten the vise against the workpiece.

Tooth Style When selecting blades, another option to consider is the shape, gullet size, teeth set and teeth angle—otherwise known as “Tooth Style." Many blade manufacturers offer variations of the four basic styles shown in Figure 37. Tooth Pitch Raker (or Standard) Usually measured as TPI (Teeth Per Inch), tooth pitch determines the size/number of the teeth. More teeth per inch (fine pitch) will cut slower, but smoother; while fewer teeth per inch (coarse pitch) will cut rougher, but faster. Skip (or Skip Tooth) As a general rule, choose blades that will have at least three teeth in the material at all times. Use fine pitched blades on harder metals and coarse pitched blades on softer metals. When selecting blades, refer to Figure 36 for recommended blade tooth (TPI) and speed (FPM) based on the workpiece material. Hook (or Claw) Variable Pitch (VP) Figure 37. Bandsaw blade tooth types.

Model G0622 (Mfd. Since 09/17) Blade Tension Squaring the Blade Proper blade tension is essential to long blade life, straight cuts, and efficient cutting times. It is always a good idea during the life of your saw to check and adjust this setting. This adjustment will improve your cutting results and extend the life of your blade. Two major signs that you do not have the correct blade tension are: 1) The blade stalls in the cut and is slipping on the wheels, and 2) the blade frequently breaks from being too loose. To tension the blade on the bandsaw: 1. Make sure the blade is tracking properly. 2. DISCONNECT BANDSAW FROM POWER! 3. Loosen and slide the blade guides as far apart as they will go then tighten them down again. 4. Turn the tension knob in Figure 53 clockwise to tighten the blade as tight as you can. 5. Using moderate finger pressure, push against the side of the blade. The blade should not move more than 0.004". To square the blade to the bed of the table: 1. DISCONNECT BANDSAW FROM POWER! 2. Separate the blade guides as far as possible, the lower the head of the bandsaw all the way until it contacts the horizontal stop. 3. Place a square on the table bed and against the edge of the blade (Figure 54), and check different points along the length of the table between the blade guides. Hex Bolt Note: We recommend using a blade tensioning gauge, like the one found in ACCESSORIES on Page 29. If you use this option please follow the instructions included with your gauge. Figure 54. Squaring the blade. 4. Model G0622 (Mfd. Since 09/17) Loosen the hex bolt shown in Figure 54, and rotate the seat until the blade is vertical to the bed, then re-tighten the hex bolt. -35- Blade Guide Bearings The blade guide bearings must be properly adjusted to make square cuts. One bearing on each assembly has an eccentric bushing that allows it to be adjusted so the blade is square to the vise. The bearings are secured in place by a hex nut and lock washer, as shown in Figure 55. To adjust the blade guide bearings: 1. DISCONNECT BANDSAW FROM POWER! 2. Position the vise to 90°, then lock it in place. 3. Put a machinist's square against the face of the vise and move it over to the blade. —The square should evenly touch both the face of the vise and the blade. If it does, skip ahead to Step 6. Before adjusting the blade guide bearings, make sure that you have squared the blade to the table as discussed in the previous section. Backing Bearing —If the square does not evenly touch the blade, but it does evenly touch the vise, continue with the next step. 4. Loosen the hex nuts that secure the eccentric bushings attached to the guide bearings. 5. Adjust the bearings as necessary to force the blade to be 90° to the vise, then re-tighten the hex nuts. 6. If any of the bearings are not touching the blade evenly, loosen the hex nuts and adjust them so the contact surface of the bearings touch the blade evenly. Hex Nut Eccentric Bushing Note: Since the bearings twist the blade into position, it is acceptable if there is 0.001"0.002" gap between the blade and the front or back of the bearing. Just make sure not to squeeze the blade too tightly with the bearings. After the guide bearings are set, you should be able to rotate the guide bearings (although they will be stiff) with your fingers. Figure 55. Blade guide adjustments. 7. -36- Adjust the backing bearing in the same manner, but leave a gap between 0.002-0.003" from the back of the blade. Model G0622 (Mfd.

Compare the manufacture date of your machine to the one stated in this manual, and study this section carefully. If there are differences between your machine and what is shown in this section, call Technical Support at (570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated wiring diagram may be available. Note: Please gather the serial number and manufacture date of your machine before calling. This information can be found on the main machine label. Wiring Safety Instructions SHOCK HAZARD. Working on wiring that is connected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components! MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts. WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections. CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source. WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components. MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box. CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors. EXPERIENCING DIFFICULTIES.
