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 flange, the arbor 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 maximum
no-load speed for one minute. Damaged
accessories 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 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 accessory 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 tool may contact hidden
wiring. Contact with a "live" wire will also make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
•
Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory 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.
FURTHER SAFETY INSTRUCTIONS FOR
ALL OPERATIONS
Kickback and Related Warnings:
•
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory. Pinching or snagging
causes rapid stalling of the rotating accessory
which in turn causes the uncontrolled 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 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 reactions 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
accessory. 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:
•
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 center 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
