tool will run out of balance, vibrate excessively and
may cause loss of control.
g) Do not use a damaged accessory. Before
each use inspect the accessories such as abra-
sive wheels for chips and cracks. If a power
tool or accessory is dropped, inspect for
damage or install an undamaged accessory.
After inspecting and installing an accessory,
position yourself and bystanders away from the
plane of the rotating accessory and run the
power tool at maximum no-load speed for one
minute. Damaged accessories will normally break
apart during this test time.
h) Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and a workshop apron capable of stop-
ping small abrasive or workpiece fragments.
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 intensity 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 accessory may fly
away and cause injury beyond immediate area of
operation.
j) Hold power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal
parts of the power tool "live" and shock the oper-
ator.
k) Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
I) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grap 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 powdered
metal may cause electrical hazards.
o) Do not operate the power tool near flam-
mable materials. Sparks could ignite these mate-
rials.

p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
4.2 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
uncontrolled power tool to be forced in the direc-
tion 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 auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kick-
back forces, if proper precautions 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. Kick-
back will propel the tool in direction opposite to the
wheel's movement at the point of snagging.
d) Use special care when working corners,
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.
e) Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create
frequent kickback and loss of control.
4.3 Safety Warnings Specific for Grinding
and Cutting-Off Operations:
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot be
adequately guarded and are unsafe.
b) The guard must be securely attached to the
power tool and positioned for maximum safety,
