Additional Safety Rules for Grinders

WARNING: The grinding wheel or accessory may loosen during coast-down of the tool when shut off. If grinding wheel or accessory loosens, it may dismount from the machine and may cause serious personal injury.

•Use of accessories not specified in this manual is not recommended 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.

•Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

•Avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel for cracks or flaws.

•Always handle and store wheels in a careful manner.

•Never cut into area that may contain electrical wiring or piping. Serious injury may result.

•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.

•Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can result in injury.

•Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times.

•Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts.

•An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is

16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

•ANSI Z87.1 eye protection (CAN/CSA Z94.3),

•ANSI S12.6 (S3.19) hearing protection,

•NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,
