Additional power tool safety warnings
Warning!
Additional safety warnings for
grinding, sanding, wire brushing, polishing
or abrasive cutting-off operations
♦
This power tool is intended to function as
a grinder, sander, wire brush, polisher or cut-
off tool. Read all safety warnings, instructions,
illustrations and speci
fi
cations provided with
this power tool.
Failure to follow all instructions
listed below may result in electric shock,
fi
re and/
or serious injury.
♦
Operations for which the power tool was not
designed may create a hazard and cause per-
sonal injury.
♦
Do not use accessories which are not speci
fi
-
cally designed and recommended by the tool
manufacturer.
Just 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
fl
y 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.
♦
The arbour size of wheels,
fl
anges, backing
pads or any other accessory must properly
fi
t the spindle of the power tool.
Accessories
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 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 acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting
and installing an accessory and run the power
tool at maximum no-load speed for one min-
ute.
Damaged accessories will normally break
apart during this test time.
♦
Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and
workshop apron capable of stopping small
abrasive or workpiece fragments.
The eye pro-
tection must be capable of stopping
fl
ying debris
generated by various operations. The dust mask
or respirator must be capable of
fi
ltering 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
fl
y away and cause injury beyond immediate
area of operation.
♦
Hold 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 shock the operator.
♦
Position the cord clear of the spinning acces-
sory.
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 ac-
cessory 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
fl
ammable
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.
Note:
The above warning does not apply for power
tools speci
fi
cally designed for use with a liquid system.
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 move-
ment 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
fi
rm 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 kick-
back forces, if proper precautions are taken.
