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 ma-
terials.
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 bind-
ing. 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 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 acces-
sory.
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
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 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 mount-
ed by flanges, the arbour hole of the accessory
must be fit the locating diameter of the flange. Ac-
cessories that do not match 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, in-
spect for damage or install an undamaged acces-
sory. 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 ca-
pable of stopping small abrasive or workpiece frag-
ments.
The eye
protection must be capable of stop-
ping 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 work-
piece or of a
broken accessory may fly away and cause
injury beyond
immediate area of operation.
-
Hold the power tool by insulated gripping surfac-
es 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 of the power tool, the cord may be
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 kick-
back
and loss of control over the power tool.
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 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 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 the cut-off wheel.
Abrasive cut-off wheels are in-
tended 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.
Wheels intended for larger power tools are not
suitable for the higher speed of a smaller tool and may
burst.
Additional safety warnings specific for abrasive
cutting off operations
-
Do not “jam” the cut-off wheel or apply excessive
pressure. Do not attempt to make an excessive depth
of cut.
Overstressing the wheel increases the loading
and susceptibility
to twisting or binding of the wheel in
the cut and the possibility of kickback or wheel breakage.
- Do not position your body in line with and behind
the rotating wheel.
When the wheel, at the point of
operation,
is moving away from your body, the possible
kickback may
propel the spinning wheel and the power
tool directly at
you.
-
When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in mo-
tion otherwise kickback may occur.
