• 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
Hz ........hertz W ............watts
min ......minutes
...........alternating current
....direct current
n
o ............no load speed
.......Class II Construction ...........safety alert symbol
........earthing terminal …/min .....revolutions per minute
Causes and Operator Prevention
of Kickback
• Kickback is a sudden reaction to a pinched, bound or misaligned
wheel, wire brush or flap disc causing an uncontrolled cut-off tool
to lift up and out of the workpiece toward the operator.
• When the wheel is pinched or bound tightly by the workpiece,
the wheel stalls and the motor reaction drives the unit rapidly
back toward or away from the operator.
• Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
• Maintain a firm grip with both hands on the unit and posi-
tion your body and arm to allow you to resist kickback
