context of clauses as illustrated below.
General Safety Rules
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 all of the warnings listed below
refers to your mains-operated (corded) power tool or battery-operated (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

- 6 -
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 ground fault circuit
interrupter (GFCI) protected supply. Use of an GFCI 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.
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,

- 7 -
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.
Special requirement for cutting off tool
Cut-off machine safety warnings
a) The guard provided with the tool must be securely attached to the power tool and
positioned for maximum safety, so the least amount of wheel is exposed towards the
operator. Position yourself and bystanders away from the plane of the rotating wheel.

- 8 -
The guard helps to protect operator from broken wheel fragments and accidental contact
with
wheel.
b) Use only bonded reinforced or diamond cut-off wheels for your power tool. Just
because an accessory can be attached to your power tool, it does not assure safe
operation.
c) 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.
d) 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.
e) Always use undamaged wheel flanges that are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel
breakage.
f) Do not use worn down reinforced wheels from larger power tools. Wheels intended for a
larger power tool are not suitable for the higher speed of a smaller tool and may burst.
NOTE The above warning does not apply for tools only designated to be used with diamond
wheels.
g) 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.
h) The arbour size of wheels and flanges must properly fit the spindle of the power tool.
Wheels and flanges 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.

- 9 -
i) Do not use damaged wheels. Before each use, inspect the wheels for chips and
cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged
wheel. After inspecting and installing the wheel, position yourself and bystanders away
from the plane of the rotating wheel and run the power tool at maximum no load speed
for one minute. Damaged wheels will normally break apart during this test time.
j) Wear personal protective equipment. Depending on application, use face shield, safety
goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves
and shop 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.
k) 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 wheel
may fly away and cause injury beyond immediate area of operation.
l) Hold the 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 could
give
the operator an electric shock.
m) 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 wheel.
n) Never lay the power tool down until the accessory has come to a complete stop. The
spinning wheel may grab the surface and pull the power tool out of your control.
o) 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.

- 10 -
p) 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.
q) Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
r) Do not use accessories that require liquid coolants. Using water or other liquid coolants
may result in electrocution or shock.
Further safety instructions for abrasive cutting-off operations
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging
causes rapid
stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in
the direction
opposite of the wheel’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

- 11 -
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 line with the rotating wheel. 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.
e) Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a
peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent
kickback and loss of control.
f) Do not ″jam″ the 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.
g) 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 wheel 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.
h) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is
restarted in the workpiece.
i) Support panels or any oversized workpiece to minimize 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.

- 12 -
j) 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.
