General Power Tool Safety Warnings

WARNING! Read all safety warnings

and all instructions. Failure to follow

the warnings and instructions may result
in electric shock, fire and/or serious
injury.

SAVE ALL WARNINGS AND INSTRUCTIONS

FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery­operated (cordless) power tool.

1) WORK AREA SAFETY

a) Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive

atmospheres, such as in the presence of
flammable liquids, gases or dust. Power

tools create sparks which may ignite the dust
or fumes.

c) Keep children and bystanders away while

operating a power tool. Distractions can
cause you to lose control.

2) ELECTRICAL SAFETY

a) Power tool plugs must match the outlet.

Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs

and matching outlets will reduce risk of
electric shock.

b) Avoid body contact with earthed or

grounded surfaces such as pipes,
radiators, ranges and refrigerators. There

is an increased risk of electric shock if your
body is earthed or grounded.

c) Do not expose power tools to rain or wet

conditions. Water entering a power tool will
increase the risk of electric shock.

d) Do not abuse the cord. Never use the

cord for carrying, pulling or unplugging
the power tool. Keep cord away from
heat, oil, sharp edges or moving parts.

Damaged or entangled cords increase the
risk of electric shock.

e) When operating a power tool outdoors,

use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use

reduces the risk of electric shock.

f) If operating a power tool in a damp

location is unavoidable, use a residual
current device (RCD) protected supply.

Use of an RCD reduces the risk of electric
shock.

3) PERSONAL SAFETY

a) Stay alert, watch what you are doing and

use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of

inattention while operating power tools may
result in serious personal injury.

b) Use personal protective equipment.

Always wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce
personal injuries.

c) Prevent unintentional starting. Ensure

the switch is in the off position before
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger

on the switch or energising power tools that
have the switch on invites accidents.

33

ENGLISH

d) Remove any adjusting key or wrench

before turning the power tool on. A

wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.

e) Do not overreach. Keep proper

footing and balance at all times. This
enables better control of the power tool in
unexpected situations.

f) Dress properly. Do not wear loose

clothing or jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery or long hair

can be caught in moving parts.

g) If devices are provided for the connection

of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce

dust-related hazards.

4) POWER TOOL USE AND CARE

a) Do not force the power tool. Use the

correct power tool for your application.

The correct power tool will do the job
better and safer at the rate for which it
was designed.

b) Do not use the power tool if the switch

does not turn it on and off. Any power
tool that cannot be controlled with the switch
is dangerous and must be repaired.

c) Disconnect the plug from the power

source and/or the battery pack from
the power tool before making any
adjustments, changing accessories, or
storing power tools. Such preventive safety

measures reduce the risk of starting the
power tool accidentally.

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 or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s 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.

ADDITIONAL SPECIFIC SAFETY RULES
Safety Instructions for All Operations

a) This power tool is intended to function as

a 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 grinding, sanding, wire

brushing, 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 does 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 use a damaged accessory. Before

each use inspect the accessory such as
abrasive wheel 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

34

ENGLISH

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 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.

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 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.

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 motor’s fan will draw the 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.

FURTHER SAFETY INSTRUCTIONS
FOR ALL OPERATIONS

Causes and Operator Prevention
of Kickback

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 reaction 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 bouncing have a tendency to snag the
rotating accessory and cause loss of control or
kickback.

35

ENGLISH

e) Do not attach a saw chain woodcarving

blade or toothed saw blade. Such blades

create frequent kickback and loss of control.

Safety Warnings Specifi c for
Grinding and 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. Flanges 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 Specifi c
for 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 increases 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 line with and

behind the rotating wheel. When the wheel,
at the point of operations, is moving away from
your body, the possible kickback may propel the
spinning wheel and the power tool directly at
you.

c) 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

36

from the cut while the wheel is in motion
otherwise kickback may occur. Investigate

and take corrective action to eliminate the cause
of wheel binding.

d) Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed
and carefully reenter the cut. The wheel may

bind, walk up or kickback if the power tool is
restarted in the workpiece.

e) Support panels or any oversized workpiece

to minimise the risk of wheel pinching and
kickback. Large workpieces tend to sag under

their own weight. Supports must be placed
under the workpiece near the line of cut and
near the edge of the workpiece on both sides of
the wheel.

f) Use extra caution when making a “pocket

cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.

Additional Safety Rules

• Use of accessories not specified in this

manual is not recommended and may be
hazardous. Use of power boosters that would

cause the tool to be driven at speeds greater
than its rated speed constitutes misuse.

• Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or

against your body leaves it unstable and may
lead to loss of control.

• Always use side handle. Tighten the handle
securely. The side handle should always be

used to maintain control of the tool at all times.

• Avoid bouncing the wheel or giving it
rough treatment. If this occurs, stop the tool

and inspect the wheel for cracks or flaws.

• Always handle and store wheels in a careful
manner.

• Never cut into area that may contain
electrical wiring or piping. Serious injury may

result.

• DO NOT cut metal with a diamond wheel.

• DO NOT use abrasive wheels.

• ALWAYS use with a dust collector.

• Do not operate this tool for long periods of
time. Vibration caused by the operating action

of this tool may cause permanent injury to
fingers, hands, and arms. Use gloves to provide
extra cushion, take frequent rest periods, and
limit daily time of use.

ENGLISH

• Air vents often cover moving parts and
should be avoided. Loose clothes, jewelry or

long hair can be caught in moving parts.

• Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, 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.

• The grinding surface of the 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.

WARNING: When not in use, place

tool on its side on a stable surface
where it will not cause a tripping
or falling hazard. Serious personal
injury may result.

Residual Risks

In spite of the application of the relevant safety
regulations and the implementation of safety
devices, certain residual risks cannot be avoided.
These are:

– Impairment of hearing.
– Risk of personal injury due to flying particles.
– Risk of burns due to accessories becoming hot

during operation.

– Risk of personal injury due to prolonged use.
– Risk of dust from hazardous substances.
