tive equipment. Fragments of workpiece
or of a broken accessory may fly away and
cause injury beyond immediate area of op-
eration.
►
Hold the power tool by insulated grip-
ping surfaces only, when performing an
operation where the cutting accessory
may contact hidden wiring.
Cutting ac-
cessory contacting a “live” wire may make
exposed metal parts of the power tool “live”
and could give the operator an electric
shock.
►
Never lay the power tool down until
the accessory has come to a complete
stop.
The spinning accessory may grab
the surface and pull the power tool out of
your control.
►
Do not run the power tool while carry-
ing it at your side.
Accidental contact with
the spinning accessory could snag your
clothing, pulling the accessory into your
body.
►
Regularly clean the power tool’s air
vents.
The motor’s fan will draw the dust
inside the housing and excessive accumu-
lation of powdered metal may cause elec-
trical hazards.
►
Do not operate the power tool near
flammable materials.
Sparks could ignite
these materials.
►
Do not use accessories that require
liquid coolants.
Using water or other liq-
uid coolants may result in electrocution or
shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled power
tool to be forced in the direction opposite of
the accessory’s rotation at the point of the
binding.
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can
dig into the surface of the material causing the
wheel to climb out or kick out. The wheel may
either jump toward or away from the operator,
depending on direction of the wheel’s move-
ment at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or con
-
ditions and can be avoided by taking proper
precautions as given below.
►
Maintain a firm grip on the power tool
and position your body and arm to
allow you to resist kickback forces. Al-
ways use auxiliary handle, if provided,
for maximum control over kickback or
torque reaction during start-up.
The
operator can control torque reactions or
kickback forces, if proper precautions are
taken.
►
Never place your hand near the rotating
accessory.
Accessory may kickback over
your hand.
►
Do not position your body in the area
where power tool will move if kickback
occurs.
Kickback will propel the tool in di-
rection opposite to the wheel’s movement
at the point of snagging.
►
Use special care when working cor-
ners, sharp edges etc. Avoid bouncing
and snagging the accessory.
Corners,
sharp edges or bouncing have a tendency
to snag the rotating accessory and cause
loss of control or kickback.
►
Do not attach a saw chain woodcarving
blade or toothed saw blade.
Such blades
create frequent kickback and loss of con-
trol.
Safety Warnings specific for Grinding and
Abrasive Cutting-Off operations
►
Use only wheel types that are recom-
mended for your power tool and the
specific guard designed for the select
-
ed wheel. Wheels for which the power tool
was not designed cannot be adequately
guarded and are unsafe.
►
The grinding surface of centre de-
pressed wheels must be mounted
below the plane of the guard lip.
An
improperly mounted wheel that projects
through the plane of the guard lip cannot
be adequately protected.
►
The guard must be securely attached
to the power tool and positioned for
maximum safety, so the least amount of
wheel is exposed towards the operator.
The guard helps to protect operator from
broken wheel fragments, accidental con-
tact with wheel and sparks that could ignite
clothing.
►
Wheels must be used only for recom-
mended applications. For example: do
not grind with the side of cut-off wheel.
Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to
these wheels may cause them to shatter.
►
Always use undamaged wheel flanges
