ers away from the plane of the rotating ac-
cessory and run the power tool at maximum
no-load speed for one minute. Damaged ac-
cessories will normally break apart during this
test time.
h) Wear personal protective equipment. De-
pending on application, use face shield,
safety goggles or safety glasses. As ap-
propriate, wear dust mask, hearing protec-
tors, gloves and workshop apron capable of
stopping small abrasive or workpiece frag-
ments. The eye protection must be capable
of stopping flying debris generated by various
operations . The dust mask or respirator must
be capable of filtrating particles generated by
your operation. Prolonged exposure to high in-
tensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken acces-
sory may fly away and cause injury beyond im-
mediate area of operation.
j) Hold the power tool by insulated gripping
surfaces only, when performing an opera-
tion where the cutting accessory may con-
tact hidden wiring or its own cord. Cutting
accessory contacting a „live“ wire may make
exposed metal parts of the power tool „live“
and could give the operator an electric shock.
k) Position the cord clear of the spinning ac-
cessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
l) Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and
pull the power tool out of your control.
m) Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
n) Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.
o) Do not operate the power tool near flam-
mable materials. Sparks could ignite these
materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or
snagged rotating wheel or any other accessory.
Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the un-
controlled 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 movement 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 conditions and
can be avoided by taking proper precautions as
given below.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use auxilia-
ry handle, if provided, for maximum control
over kickback or torque reaction during
start-up. The operator can control torque re-
actions or kickback forces, if proper precau-
tions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area where
power tool will move if kickback occurs.
Kickback will propel the tool in direction op-
posite to the wheel’s movement at the point of
snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snag-
ging the accessory. Corners, sharp edges or
bouncing have a tendency to snag the rotating
