breakage.
f) 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.
g) 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.
h) Do not use damaged wheels. Before
each use, inspect the wheels for chips
and cracks. If the 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 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.
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 fly away and cause injury
beyond immediate area of operation.
k) 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.
l) Regularly clean the power tool's air vents.
The motor's fan can draw the dust inside
the housing and excessive accumulation
of powdered metal may cause electrical
hazards.
m) Do not operate the power tool near
EN
flammable materials. Do not operate the
power tool while placed on a combustible
surface such as wood. Sparks could ignite
these materials.
n) Do not use accessories that require liquid
coolants. Using water or other liquid
coolants may result in electrocution or
shock.
o) Wear protective gloves when handling
wheels.
p) The cut-off machine is always used on a
stable and level surface.
2) 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 cutting
unit to be forced upwards toward the operator.
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. 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. The operator can
control upward kickback forces, if proper
precautions are taken.
b) Do not position your body in line with the
rotating wheel. If kickback occurs, it will
propel the cutting unit upwards toward the
operator.
c) 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.
d) 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.
e) When the wheel is binding or when
interrupting a cut for any reason, switch
