When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this man-
ual. Use of unauthorized parts or failure to follow Maintenance
instructions may create a risk of electric shock or injury.
Specific Safety Rules for Grinders
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.
Refer to the table below. Accessory ratings must always be
above tool speed as shown on tool nameplate.
NOTE: The rated no load tool speed is printed on the name plate
and embossed on the gear case.

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.
Before using, inspect recommended accessory for cracks
or flaws. If such a crack or flaw is evident, discard the acces-
sory. The accessory should also be inspected whenever you
think the tool may have been dropped. Flaws may cause wheel
breakage.

When starting the tool with a new or replacement wheel, a
new or replacement wire brush installed, or if you are
unsure of the condition of the wheel, 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.
In operation, avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the wheel for
cracks and flaws.
Direct sparks away from operator, bystanders or flamma-
ble materials. Sparks may be produced while using a sander
or grinder. 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.
Clean out your tool often, especially after heavy use. Dust
and grit containing metal particles often accumulate on interior
surfaces and could create a risk of serious injury, electric
shock or electrocution.
Do not operate this tool for long periods of time. Vibration
caused by tool action may be harmful to your hands and arms.
Use gloves to provide extra cushion and limit exposure by taking
frequent rest periods.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chem-
icals known to cause cancer, birth defects, or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
