into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result
in a hazardous situation.
5) Service
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
Additional Specific Safety Instructions for
Cut-Off Machines
a ) The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders
away from the plane of the rotating wheel. The
guard helps to protect operator from broken wheel
fragments and accidental contact with wheel.
b ) Use only bonded reinforced wheels for your
power tool. Just because an accessory can be
attached to your power tool, it does not assure
safe operation.
c ) 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.
d ) Wheels must be used only for recommended
applications. For example: do not grind with the
side of cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces applied to
these wheels may cause them to shatter.
e ) Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
f ) Do not use worn down reinforced wheels from
larger power tools. Wheels intended for a larger
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 arbor 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 filtrating 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 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.
m ) 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.
n ) 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.
o ) 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.
p ) 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.
q ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
r ) 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
