Always use an extension cord that uses a ground pin and connected ground wire. Use an extension cord that meets the amp rating on the motor nameplate. If the motor is dual voltage, be sure to use the amp rating for the voltage you will be using. If you use an extension cord with an undersized gauge or one that is too long, excessive heat will be generated within the circuit, increasing the chance of a fire or damage to the circuit. 17. KEEP PROPER FOOTING AND BALANCE at all times. 18. DO NOT LEAVE MACHINE UNATTENDED. Wait until it comes to a complete stop before leaving the area. 19. PERFORM ALL MACHINE MAINTENANCE. Follow lubrication and accessory attachment instructions in the manual. 20. KEEP MACHINE AWAY FROM OPEN FLAME. Operating machines near pilot lights or open flames creates a high risk if dust is dispersed in the area. Dust particles and an ignition source may cause an explosion. Do not operate the machine in high-risk areas, including but not limited to, those mentioned above. 21. IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES performing the intended operation, stop using the machine! Then contact our service department or ask a qualified expert how the operation should be performed. 22. HABITS—GOOD AND BAD—ARE HARD TO BREAK. Develop good habits in your shop and safety will become second nature to you. -4 M1107 Bench grinder Additional Safety Instructions for Grinder USE this and other machinery with caution and respect. Always consider safety first, as it applies to your individual working conditions. No list of safety guidelines can be complete—every shop environment is different. Failure to follow guidelines could result in serious personal injury, damage to equipment or poor work results. READ and understand this entire instruction manual before using this machine. Serious personal injury may occur if safety and operational information is not understood and fol- lowed. DO NOT risk your safety by not reading! 1. EYE PROTECTION. Grinding causes small particles to become airborne at a high rate of speed. ALWAYS wear safety glasses when using this machine. 2. MOUNTING TO BENCH/STAND. An unsecured grinder may become dangerously out of control during operation. Make sure grinder is FIRMLY secured to a bench/stand before use. 3. WHEEL SPEED RATING. Wheels operated at a faster speed than rated for may break or fly apart. Before mounting a new wheel, be sure the wheel RPM rating is equal or higher than the speed of the grinder. 4. WHEEL FLANGES. Only use the flanges included with the grinder when mounting wheels. Other flanges may not properly secure the wheel and cause an accident. 5. RING TEST. Perform a “ring test” on grinding wheels before installation to ensure that they are safe to use. A wheel that does not pass the ring test may break or fly apart during operation. 6. STARTING GRINDER. If a wheel IS damaged, it will usually fly apart shortly after start-up. To protect yourself, always stand to the side of the grinder when turning it ON, allow it to gain full speed and wait for at least 1 minute before standing in front of it. 7. LUNG PROTECTION. Grinding produces hazardous dust, which may cause long-term respiratory problems if breathed. Always wear a NIOSH approved dust mask or respirator when grinding. 8. SIDE GRINDING. Grinding on the side of wheels can cause them to break and fly apart—unless the wheel is rated for side grinding. 9. TOP GRINDING. Grinding on the top of wheels greatly increases the risk of workpiece kickback. Always grind on the downward part of the wheel. 10. HAND/WHEEL CONTACT. Grinding wheels have the capability of removing a lot of skin fast. Keep a firm grip on the workpiece and position your hands a safe distance away when grinding. Avoid wearing gloves as they may get caught in the grinding wheel and cause even more serious entanglement injuries. 11. TOOL REST POSITION. If the tool rest is too far away from the wheel, the workpiece may be pulled down, causing loss of control and pulling your hand into the grinding wheel. Keep the tool rest within 1.8" from the wheel when operating. SAFETY -5 M1107 Bench grinder ELECTRICAL SAFETY 110V Operation Your bench grinder needs a 110 volt power supply. When choosing a power supply outlet for the Model M1107 bench grinder, use a circuit that is protected with a 15 amp circuit breaker or fuse. Keep in mind that a circuit being used by other machines or tools at the same time will add to the total load being applied to the circuit. Add up the load ratings of all machines on the circuit. If this number exceeds the rating of the circuit breaker or fuse, use a different circuit. Extension Cords When it is necessary to use an extension cord, use the following guidelines: • Use cords rated for Standard Service. • Never exceed a length of 50 feet. • Use cords with 14 ga. wire or bigger. • Insure cord has a ground wire and pin. • Do not use cords in need of repair. Grounding This grinder must be grounded! The electrical cord supplied ...
