See table, “Extension Cord Specifications”, on page 18. IMPORTANT SAFETY RULES FOR BENCH GRINDERS ALWAYS wear protective eyewear and/or appropriate dust filters and respirator when using this tool. DO NOT OPERATE THIS BENCH GRINDER until it is completely assembled according to the instructions in this manual. Failure to adhere to these instructions could result in serious and/or permanent injury. OBTAIN ADVICE FROM A QUALIFIED INDIVIDUAL if you are not completely sure how to use the bench grinder. USE RECOMMENDED ACCESSORIES. Consult the owners manual for recommended accessories. The use of improper accessories may cause cause risk of injury. NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted. CHECK DAMAGED PARTS. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced. DIRECTION OF FEED. Only feed work into a blade or cutter against the direction of rotation of the blade or cutter. GROUNDING INSTRUCTIONS The electrical power source for this bench grinder MUST be grounded in order prevent possible electric shock or even death should the tool malfunction or breakdown. Grounding provides a path of least resistance for electric current thus reducing the risk of electrical shock. The power source must also use a minimum 20A service and not used if other power tools on the same circuit are in use. This bench grinder is equipped with a grounded 3-wire power cord with a 3-prong plug. If the power cord will not fit into the wall plug, an approved adapter can be used as long as it is connected to the center screw in the wall plate. Never modify the electrical plug by cutting off the grounding prong so it will fit into unapproved, un-grounded electrical receptacles. See Figure 1. If you have questions about hooking up the bench grinder, contact a certified electrical contractor to install the proper circuitry acceptable for this and other power tools you use. Repair or replace any damaged electrical wiring IMMEDIATELY. 5 6 FIGURE 1.

Loose fragments could fly off at high speeds possibly causing injury. NEVER ENGAGE A WORK PIECE TO A COLD GRINDING STONE. A cold grinding stone has a tendency to chip. Allow the grinder to run for an entire minute before applying the work piece to the grinding stone. NEVER START THE BENCH GRINDER WITH THE WORK PIECE AGAINST THE GRINDING WHEEL. The work piece can be drawn into the grinding wheel causing it to fragment resulting in damage to the grinder and/or serious injury to the operator. THOROUGHLY CLEAN THE GRINDER BEFORE CHANGING TYPES OF WORK PIECES. Combining wood and metal dust can result in an explosion or fire. DO NOT GRIND OR POLISH WORK PIECES MADE OF MAGNESIUM. The magnesium could ignite resulting in a very intense fire that could cause severe burns to the operator and/or seriously damage the bench grinder. NEVER PERFORM GRINDING OPERATIONS NEAR FLAMMABLE GAS OR LIQUIDS. The resulting fire and/or explosion could cause permanent serious injuries to the operator and damage to the grinder and surrounding work area. AVOID AWKWARD POSITIONS for both hands and work pieces. A sudden slip could draw fingers into the grinding wheel causing injury. ALWAYS KEEP ARMS, HANDS, AND FINGERS away from the grind wheel surface. Severe injury could result. HOLD THE WORK PIECE FIRMLY AGAINST THE GRINDING WHEEL. A loose grip can cause loss of control of the work piece resulting in severe injuries or damage to the bench grinder. ALWAYS MAKE CONTACT WITH THE FACE OF THE GRINDING STONES. Grinding objects on the side of the grinding stones can cause the stones to fragment resulting in fragments being thrown from the wheel at high speeds. Serious injury could result. NEVER APPLY A COOLANT DIRECTLY TO THE WORK PIECE WHILE IT IS IN CONTACT WITH THE GRINDING STONE. Coolant can weaken the makeup of the grinding stones causing them to fail. Dip the work piece in water to cool it. DO NOT TOUCH THE GROUND PORTION OF THE WORKPIECE until it has properly cooled. Touching HOT surfaces can cause injury. NEVER PERFORM LAYOUT OR ASSEMBLY to work pieces in front of the grinder while it is still running. A sudden slip could bring hands in contact with the moving parts of the bench grinder resulting in injury to the operator. 7 8 FOLLOW ALL WIRING CODES. Use only properly grounded three-hole grounded receptacles. DO NOT cut the third prong off the power cord. W...
