c) Do not use accessories which are not specifi-
cally designed and recommended by the tool
manufacturer. Just because the accessory
can be attached to your power tool, it does not
assure safe operation.
d) The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fly apart.
e) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
f) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbour hole of the acces-
sory must fit the locating diameter of the flange.
Accessories that do not match the mounting hard-
ware 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 wires. If power tool or accessory is
dropped, inspect for damage or install an unda-
maged 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 appropriate, wear dust mask,
hearing protectors, gloves and workshop 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. Frag-
ments of workpiece or of a broken accessory
may fly away and cause injury beyond immedia-
te area of operation.
j) Hold the power tool by insulated gripping surfa-
ces only, when performing an operation where
the cutting accessory may contact hidden
wiring or its own cord.Cutting accessory con-
tacting 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 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.
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
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 hou-
sing 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 cool-
ants. 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 sna-
gged 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 movement at the point of pinching. Abrasive
wheels may also break under these conditions. Kick-
back is the result of power tool misuse and/or incor-
rect 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 po-
sition 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.
