the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the
accessory must fit the locating diameter of the
flange. Accessories that do not match the mounting
hardware of the power 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 accessory such as abrasive wheels
for chips and cracks, backing pad for cracks, tear
or excess wear, wire brush for loose or cracked wi-
res. If 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 noload speed for one minute.
Damaged accessories 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 appropriate, wear
dust mask, hearing protectors, gloves and shop
apron capable of stopping 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 the power tool by insulated gripping sur-
faces 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 could give the operator an electric shock.
k) Position the cord clear of the spinning accesso-
ry. If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spinning
wheel.
l) Never lay the power tool down until the acces-
sory 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 acces-
sory 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 flammable
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. Pinching or snagging cau-
ses rapid stalling of the rotating wheel which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the wheel'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. Ab-
rasive 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 kickback forces, if proper
precautions are taken.
b) Never place your hand near the rotating ac-
cessory. 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 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.toothed saw blade.
Safety Warnings Specific for Grinding:
a) Use only wheel types that are recommended
for your power tool and the specific guard desi-
gned for the selected wheel. Wheels for which the
power tool was not designed cannot be adequately
guarded and are unsafe.
b) The grinding surface of the centre depressed
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.
c) The guard must be securely attached to the
power tool and positioned for maximum safety,
