General Power Tools Safety Warnings
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, re and/or serious
injury.
WARNING! Read all safety warnings designated by the symbol and all instructions.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
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
ammable 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.
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.
Unmodied 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) The use of a residual current device (RCD) when using this tool is recommended.
Use of an RCD reduces the risk of electric shock.
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 inuence 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.

General Power Tools Safety Warnings
Personal Safety (continued)
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,
ensure these are connected and properly used.
Use of dust collection can reduce dust-related hazards.

Helpline No 0333 2000 336
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.
a) Keep all parts of the body away from the saw chain when the chain saw
is operating. Before you start the chain saw, make sure the saw chain is not
contacting anything.
A moment of inattention while operating chain saws may cause entanglement of your
clothing or body with the saw chain.
b) Always hold the chain saw with your right hand on the rear handle and your
left hand on the front handle.
Holding the chain saw with a reversed hand conguration increases the risk of personal
injury and should never be done.

Safety warnings specic to the product (continued)
c) Wear safety glasses and hearing protection. Further protective equipment for
head, hands, legs and feet is recommended.
Adequate protective clothing will reduce personal injury by ying debris or accidental
contact with the saw chain.
d) Do not operate a chain saw in a tree.
Operation of a chain saw while up in a tree may result in personal injury.
e) Always keep proper footing and operate the chain saw only when standing on
xed, secure and level surface.
Slippery or unstable surfaces such as ladders may cause a loss of balance or control
of the chain saw.
f) When cutting a limb that is under tension be alert for spring back.
When the tension in the wood bres is released the spring loaded limb may strike the
operator and/or throw the chain saw out of control.
g) Use extreme caution when cutting brush and saplings.
The slender material may catch the saw chain and be whipped toward you or pull you
off balance.
h) Carry the chain saw by the front handle with the chain saw switched off and
away from your body. When transporting or storing the chain saw, always t the
guide bar cover.
Proper handling of the chain saw will reduce the likelihood of accidental contact with the
moving saw chain.
i) Follow instructions for lubricating, chain tensioning and changing accessories.
Improperly tensioned or lubricated chain may either break or increase the chance for kickback.
j) Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
k) Cut wood only. Do not use chain saw for purposes not intended. For example, do not
use chain saw for cutting plastic, masonry or non-wood building materials.
Use of the chain saw for operations different than intended could result in a hazardous
situation.
l) Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw
chain along the top of the guide bar may push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of the saw which could result in serious
personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain
saw user, you should take several steps to keep your cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and
can be avoided by taking proper precautions as given below:

Helpline No 0333 2000 336
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.
b)If the replacement of the supply cord is necessary, this has to be done by the
manufacturer or his agent in order to avoid a safety hazard.
General Power Tools Safety Warnings
unexpected situations.
o) Only use replacement bars and chains specied by the manufacturer.
Incorrect replacement bars and chains may cause chain breakage and/or kickback.
p) Follow the manufacturer’s sharpening and maintenance instructions for the saw
chain.
Decreasing the depth gauge height can lead to increased kickback.
Service
Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let
go of the chain saw.
n) Do not overreach and do not cut above shoulder height.
This helps prevent unintended tip contact and enables better control of the chain saw in
Safety warnings specic to the product (continued)
m) Maintain a rm grip, with thumbs and ngers encircling the chain saw handles, with
both hands on the saw and position your body and arm to allow you to resist kickback
forces.
