• Do not use accessories which are not specifically
designed and recommended by the tool manufac-
turer. J
ust because the accessory can be attached
to your power tool, it does not assure safe operation.
•
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.
• 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.
•
Threaded mounting of accessories must match the
grinder spindle thread. For accessories mounted
by flanges, the arbour hole of the accessory must
fit the locating diameter of the flange.
Accessories
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 a damaged accessory. Before each use
inspect the accessory such as abrasive wheels for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of the
rotating accessory and run the power tool at maxi-
mum no-load speed for one minute.
Damaged ac
-
cessories 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 workshop 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 ex
-
posure 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 accessory may fly away
and cause injury beyond immediate area of operation.
•
Hold the power tool by insulated gripping sur-
faces only, when performing an operation where
the cutting tool may contact hidden wiring or its
own cord.
Contact with a "live" wire may also 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 accessory.
•
Never lay the power tool down until the accessory
has come to a complete stop.
The spinning acces
-
sory 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 cool-
ants.
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, backing pad, brush or any other acces
-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon
-
trolled 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 in
-
correct 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 reac
-
tions or kickback forces, if proper precautions are taken.
•
Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
•
Do not position your body in the area where power
tool will move if kickback occurs.
Kickback will
propel the tool in direction opposite to the wheel’s
movement at the point of snagging.
•
Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the ac-
cessory.
Corners, sharp edges or bouncing have a
tendency to snag the rotating accessory and cause
loss of control or kickback.
•
Do not attach a saw chain woodcarving blade or
toothed saw blade.
Such blades create frequent
kickback and loss of control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations:
•
Use only wheel types that are recommended for
your power tool and the specific guard designed
for the selected wheel.
Wheels for which the power
tool was not designed cannot be adequately guarded
and are unsafe.
•
The grinding surface of centre depressed wheels
must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the
plane of the guard lip cannot be adequately protected.
•
The guard must be securely attached to the power
tool and positioned for maximum safety, so the
least amount of wheel is exposed towards the
operator.
The guard helps to protect the operator
from broken wheel fragments, accidental contact with
wheel and sparks that could ignite clothing.
•
Wheels must be used only for recommended ap-
plications. 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 size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be different from grinding wheel flanges.
•
Do not use worn down wheels from larger power
tools.
Wheel intended for larger power tool is not suit
-
able for the higher speed of a smaller tool and may burst.
