CUT-OFF MACHINE SAFETY
WARNINGS
•
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.
•
Use only bonded reinforced or diamond cut-off wheels
for your power tool. Just because an accessory can be
attached to your power tool, it does not assure safe
operation. NOTE: Use the wording "bonded reinforced"
or "diamond" as applicable depending on the designation
of the tool.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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
English
generated by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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.
•
Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
•
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.
•
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
