Wheels
and
fl
anges 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.
h) 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.
i) 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
fl
ying
debris generated by various operations. The dust mask
or respirator must be capable of
fi
ltrating particles
generated by your operation. Prolonged exposure to
high intensity noise may cause hearing loss.
j) 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
fl
y away and cause injury beyond immediate area of
operation.
k) Hold the 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 could
give the operator an electric shock.
l) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged and
your hand or arm may be pulled into the spinning wheel.
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
fl
ammable
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.
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes 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. 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
fi
rm 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 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 o
ff
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.
