missing or damaged. If grinding wheel or accessory loosens, it may dismount from the machine and may cause serious personal injury.
•Always use proper guard with grinding wheel. A guard pro- tects operator from broken wheel fragments and wheel contact.
•Accessories must be rated for at least the speed recom- mended on the tool warning label. Wheels and other acces- sories running over rated speed can fly apart and cause injury. Accessory ratings must be above listed minimum wheel speed as shown on tool nameplate.
•Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
•Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can result in injury.
•ALWAYS WEAR EYE PROTECTION WHEN USING THIS TOOL.
•Use of accessories not specified in this manual is not rec- ommended and may be hazardous. Use of power boosters that would cause the tool to be driven at speeds greater than its rated speed constitutes misuse.
•Do not use circular saw blades or any other toothed blades with this tool. Serious injury may result.
•When starting the tool with a new or replacement wheel, or a new or replacement wire brush installed, hold the tool in a well protected area and let it run for one minute. If the wheel has an undetected crack or flaw, it should burst in less than one minute. If the wire brush has loose wires, they will be detected. Never start the tool with a person in line with the wheel. This includes the operator.
•Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel for cracks or flaws.
•Direct sparks away from operator, bystanders or flammable materials. Sparks may be produced while cutting and/or grinding. Sparks may cause burns or start fires.
•Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times.
•Never cut into area that may contain electrical wiring or piping. Serious injury may result.
•Clean out your tool often, especially after heavy use. Dust and grit containing metal particles often accumulate on interior surfaces and could create an electric shock hazard.
•Do not operate this tool for long periods of time. Vibration caused by the operating action of this tool may cause permanent injury to fingers, hands, and arms. Use gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.
•Direct the Dust Ejection System (DES) away from operator and coworkers. Serious injury may result (Fig. 1, K).
•The label on your tool may include the following symbols. The symbols and their definitions are as follows:
V | volts | A | amperes | |||
