Resumen del manual
To operate this or any power tool safely and efficiently, become as familiar with it as possible. The time you invest before you begin to use your Model H4378/H4379 will be time well spent. DO NOT operate this machine until you are completely familiar with the contents of this manual, or serious personal injury may occur. 8. DO NOT stand directly in front of grinding wheels when turning machine on. 9. PERFORM a “ring test” (see page 12) on grinding wheels to ensure that they are safe for use. Always inspect grinding wheels before operation. 10. HOLD THE WORKPIECE FIRMLY WHILE GRINDING. 11. DO NOT allow your hands to come into contact with grinding wheels during operation. Abrasive accessories have the ability to remove a lot of material, including skin, very quickly. However, do not wear gloves while grinding, they may get caught in the grinding wheel. 12. KEEP TOOL REST AS CLOSE AS POSSIBLE TO GRINDING WHEEL. 13. NEVER GRIND BY PLACING THE WORKPIECE ON TOP OF THE WHEEL. The wheel may kick the work- piece toward the operator. Always grind on the downward part of the wheel. 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 follow guidelines could result in serious personal injury, damage to equipment or poor work results. -4- H4378/H4379 Slimline Bench Grinder SECTION 2: CIRCUIT REQUIREMENTS 110V Operation The Model H4378 is wired for 110V and will draw 2.5 amps. The Model H4379 is wired for 110V and will draw 3.5 amps. If you operate this machine 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. A 10 amp dedicated circuit should be used with this grinder. Always check to see if your current wires are capable of handling a 10 amp load. If you are unsure, consult the advice of a qualified electrician. Extension Cords If you find it necessary to use an extension cord with the Model H4378/H4379, make sure the cord is rated Hard Service (grade S) or better. Refer to the chart in the standard safety instructions to determine the minimum gauge for the extension cord. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged. Grounding In the event of an electrical short, grounding reduces the risk of electric shock by providing electric current a path of least resistance. This tool is equipped with a power cord having an equipment-grounding conductor. See Figure 1B. The outlet must be properly installed and grounded in accordance with all local codes and ordinances. This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur. Figure 1A. Do not remove grounding pin. Figure 1B. Typical 110V plug and outlet.
