Safety Warnings Specific for Wire

Brushing Operations

a)Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate fight clothing and/or skin.

b)If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces.

Additional Safety Rules for Grinders

A WARNING: The grinding wheel or accessory may loosen during coast=down of the tool when shut off. /f 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 too/to be driven at speeds greater than its rated speed constitutes misuse.

•Use clamps or anotherpractical 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 manne_

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 too/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.

When the gear case grip is properly installed, the use of the side handle is not required.

When not in use, place grinder on a stable surface where it will not move inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury may result.

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 numbed the heavier the cord.
