Electrical shock can cause serious or fatal injury. Follow the National Electrical Code (NEC) and local codes for the safe installation of this equipment. 1. All grounded, cord–connected grinders: In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This grinder is equipped with an electric cord having an equipment–grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified electrician. Improper connection of the equipment–grounding conductor can result in a risk of electric shock. The “Green” insulated wire (with or without yellow stripes) is the equipment–grounding conductor. If repair or replacement of the electric cord is necessary, do not connect the equipment–grounding conductor to a live terminal. Check with a qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded. Use only 3–wire extension cords that have 3–prong grounding plugs and 3–pole receptacles that accept the tool’s plug. Repair or replace damaged or worn cord immediately. 2. Grounded, cord–connected grinders intended for use on a supply circuit having a nominal rating less than 150 volts: This grinder is intended for use on a circuit that has an outlet that looks like the one illustrated n Figure A. The tool has a grounding plug that looks like the plug illustrated in Figure A. A temporary adapter, which looks like the adapter illustrated in Figures B and C, may be used (except in Canada) to connect this plug to a 2–pole receptacle as shown in Figure B if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green–colored rigid ear, lug, etc. extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box. 3. Grounded, cord–connected tools intended for use on a supply circuit having a nominal rating between 150–250 volts, inclusive: This grinder is intended for use on a circuit that has an outlet that looks like the one illustrated in Figure D. The grinder has a grounding plug that looks like the plug illustrated in Figure D. Make sure the grinder is connected to an outlet having the same configuration as the plug. No adapter is available, or should be used, with this grinder. If the grinder must be reconnected for use on a different type of electric outlet, the reconnection should be made by qualified service personnel; and after reconnection, the grinder should comply with all local codes and ordinances.

Permanently connected grinders: This grinder should be connected to a grounded, metal, permanent wiring system; or to a system having an equipment–grounding conductor.

Operation WARNING: Do not operate this grinder until you are sure that you are completely familiar with the safe operation of the grinder, all accessories and safety equipment. Improper use can lead to severe injury. This manual defines proper use of this equipment. Before using this equipment for any other use, please consult Baldor. Contact Baldor if you do not understand any procedure or operation concerning this grinder or this manual. WARNING: When starting a grinder for the first time, or after installing a replacement grinding wheel, it is most important that the operator stand aside for at least one minute of rotation at full speed. This is the correct practice since grinding wheels can disintegrate if they have received damage during shipping or handling. Check that the On–Off switch is in the “OFF” position, and the grinding wheel and wheel move freely. When starting the grinder for the first time or after replacing a wheel, it is important that the operator stand aside for at least one minute of operation at speed. This will ensure that operation will be safe from debris. After connecting grinder to power source, turn switch on. Grinder should come up to speed smoothly and without vibration. If grinder does not, shut grinder off immediately and determine reason. As grinding wheel wears, maintain 1/8 . or less clearance between tool rest and grinding wheel and spark arrestor and grinding wheel. Grind on grinding face (periphery) of wheels only. MN903 Maintenance WARNING: Prevent electrical shock hazard and accidental machine operation. Always disconnect grinder from the power source before servicing, changing accessories (such as wheels, tool rest, spark arrestor, etc.) or before performing maintenance. WARNING: Never install a wheel that is damaged, such as a ...
