power tool are not suitable for the higher speed of a
smaller tool and may burst.
g ) 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.
h ) The arbour size of wheels and flanges must
properly fit the spindle of the power tool. Wheels
and flanges with arbour holes that do not match the
mounting hardware of the power tool will run out
of balance, vibrate excessively and may cause loss
of control.
i ) Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If power
tool or wheel is dropped, inspect for damage or
install an undamaged wheel. After inspecting
and installing the wheel, position yourself and
bystanders away from the plane of the rotating
wheel and run the power tool at maximum no
load speed for one minute. Damaged wheels will
normally break apart during this test time.
j ) Wear personal protective equipment. Depending
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
filtering particles generated by your operation.
Prolonged exposure to high intensity noise may cause
hearing loss.
k ) 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 wheel may fly away and
cause injury beyond immediate area of operation.
l ) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hidden
wiring. Cutting accessory contacting a "live" wire may
make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
m ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
n ) 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.
o ) 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.
p ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
q ) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR
ABRASIVE CUTTING‑OFF OPERATIONS
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
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 reaction or kickback 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 line with the
rotating wheel. 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,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f ) Do not "jam" the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
the wheel in the cut and the possibility of kickback or
wheel breakage.
g ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove
the wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate
