GENERAL POWER TOOL SAFETY WARNINGS
RULES FOR SAFE OPERATION
d) Store idle power tools out of the reach of
children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for
misalignment of binding or moving parts,
breakage of parts and any other condition
that may affect the power tools' operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and tool
bits etc., in accordance with these
instructions, taking into account the
working conditions and the work to be
performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a
qualified repair person using only
identical replacement parts. This will
ensure that the safety of the power tool is
maintained.
SPECIFIC SAFETY WARNINGS
Safety Warnings Common for Grindin g,
¡ ö
Sanding, Wire Brushing or Abrasive
Cutting-Off Operations:
a) This power tool is intended to function as
a grinder, sander, wire brush or cut-off
tool. Read all safety warnings,
instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious injury.
b) Operations such as polishing are not
recommended to be performed with this
power tool. Operations for which the power
tool was not designed may create a hazard
and cause personal injury.
c) Do not use accessories which are not
specifically designed and recommended
by the tool manufacturer. Just because the
accessory can be attached to your power
tool, it dose not assure safe operation.
d) 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.
e) 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.
f) The arbour size of wheels, flanges,
backing pads or any other accessory
must properly fit 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.
g) Do not ues a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels 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.
h) Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As
application, wear dust mask, hearing
protectors 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.
i) 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.
j) 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.
k) Position the cord clear of the spining
accessory. If you lose control, the cord may
be cut or snagged and your hand or arm may
be pulled into the spinning accessory.

SPECIFIC SAFETY WARNINGS
l) 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.
m) 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.
n) Regularly clean the power tool's air vents.
The motors fan will draw dust inside the
housing and excessive accumulation of
powdered metal may cause electrical
hazards.
o) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid
coolants may result in electrocution or shock.
Kickback and Related Warnings
¡ ö
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.
a) 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.
b) Never place your hand near the rotating
accessory. Accessory may kickback over
your hand.
c) 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.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bounciing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.
e) 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
¡ ö
Abrasive Cutting-Off Operations:
a) 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.
b) 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 and accidental
contact with wheel.
c) 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.
d) 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.
langes for
cut-off wheels may be different from grinding
wheel flanges.
e) Do not use worn down wheels from larger
power tools. Wheel intended for larger
power tool is not suitable for the higher speed
of a smaller tool and may burst.
Additional Safety Warnings Specific for
¡ ö
Abrasive Cutting-Off Operations:
a) Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt to
make an excessive depth of cut.
Overstressing the wheel increase the loading
and susceptibility to twisting or binding of the
wheel in the cut and the possibility of
kickback or wheel breakage.
b) Do not position your body in the line with
and behind the rotating wheel. When the
wheel, at the point of operation, is moving
away from your body, the possible kickback
