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 battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
4. 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.
5. 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.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. 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.
9. 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.
10. Use of power supply via a RCD with a rated
residual current of 30mA or less is always
recommended.
Personal safety
11.
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.
moment of inattention while operating power tools
may result in serious personal injury.
12. 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.
13. 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.
14. 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.
15. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
16.
Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing, and gloves
away from moving parts.
or long hair can be caught in moving parts.
17.
If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used.
dust collection can reduce dust-related hazards.
Power tool use and care
18. 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.
19. 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.
20.
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.
the risk of starting the power tool accidentally.
21. 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.

GEB037-8
Chain saw safety warnings
1.
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.
while operating chain saws may cause entanglement
of your clothing or body with the saw chain.
2. 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 configuration increases the risk of
personal injury and should never be done.
3. Hold the power tool by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring or its own cord. Saw
chains contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
4. 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
flying debris or accidental contact with the saw
chain.
5. Do not operate a chain saw in a tree. Operation
of a chain saw while up in a tree may result in
personal injury.
6. Always keep proper footing and operate the
chain saw only when standing on fixed,
secure and level surface. Slippery or unstable
surfaces such as ladders may cause a loss of
balance or control of the chain saw.
A moment of inattention
7. When cutting a limb that is under tension be
alert for spring back. When the tension in the
wood fibres is released the spring loaded limb
may strike the operator and/or throw the chain
saw out of control.
8. 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.
9. 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 fit the guide bar cover.
Proper handling of the chain saw will reduce the
likelihood of accidental contact with the moving
saw chain.
10. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
12. 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.
13. 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:
−
Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both
hands on the saw and position your body
and arm to allow you to resist kickback
forces.
Kickback forces can be controlled by the
operator, if proper precautions are taken. Do not
let go of the chain saw.

014316
− 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 unexpected
situations.
− Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
− Follow the manufacturer’s sharpening
and maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased kickback.
ADDITIONAL SAFETY RULES
1. Read the instruction manual in order to familiarize
yourself with operation of the chain saw.
2. Before using the chain saw for the first time,
arrange to have instruction in its operation. If this
is not possible, at least practice cutting round
timber on a trestle before beginning work.
3. The chain saw must not be used by children or
young persons under 18 years of age. Young
persons over 16 years of age may be exempted
from this restriction if they are undergoing training
under the supervision of an expert.
4. Working with the chain saw requires a high level
of concentration. Do not work with the saw if you
are not feeling fit and well. Carry out all work
calmly and carefully.
5. Never work under the influence of alcohol, drugs
or medication.
Proper use
1. The chain saw is intended solely for cutting wood.
Do not use it for example to cut plastic or porous
concrete.
2. Only use the chain saw for operations described
in this instruction manual. Do not, for example,
use it to trim hedges or for similar purposes.
3. The chain saw must not be used for forestry work,
i.e. for felling and limbing standing timber. The
chain saw cable does not provide the operator
with the mobility and safety required for such
work.
4. The chain saw is not intended for commercial use.
5. Do not overload the chain saw.
Personal protective equipment
1. Clothing must be close-fitting, but must not
obstruct mobility.
2. Wear the following protective clothing during
work:
• A tested safety helmet, if a hazard is
presented by falling branches or similar;
• A face mask or goggles;
• Suitable ear protection (ear muffs, custom or
mouldable ear plugs). Octave brand analysis
upon request.
• Firm leather safety gloves;
• Long trousers manufactured from strong
fabric;
• Protective dungarees of cut-resistant fabric;
• Safety shoes or boots with non-slip soles,
steel toes, and cut-resistant fabric lining;
• A breathing mask, when carrying out work
which produces dust (e.g. sawing dry wood).
Protection against electric shock
･ The chain saw must not be used in wet
weather or damp environments, as the
electric motor is not waterproof.
1. Only plug the saw into sockets in tested electrical
circuits. Check that the system voltage matches
that on the rating plate. Ensure that a 16 A line
fuse is fitted. Saws used in the open air must be
connected to a residual current-operated circuitbreaker with an operating current no higher than
30 mA.
･ Should the connecting cable be
damaged, withdraw the mains plug
immediately.
Safe working practices
1. Before starting work, check that the chain saw is
in proper working order and that its condition
complies with the safety regulations. Check in
particular that:
• The chain brake is working properly;
• The run-down brake is working properly;
• The bar and the sprocket cover are fitted
correctly;
• The chain has been sharpened and tensioned
in accordance with the regulations;
• The mains cable and mains plug are
undamaged;
Refer to the "CHECKS " section.
2. Always ensure in particular that the extension
cable used is of adequate cross-section (see
"SPECIFICATIONS"). When using a cable reel,
wind the cable completely off the reel. When
5
using the saw in the open air, ensure that the
cable employed is intended for open-air use and
is rated accordingly.
3. Keep the cord away from the cutting area and to
position cord so that it will not be caught on
branches, and the like, during cutting.
4. Do not operate the chain saw in the vicinity of
flammable dust or gases, as the motor generates
sparks and presents a risk of explosion.
5. Work only on firm ground and with a good footing.
Pay particular attention to obstacles (e.g. the
cable) in the working area. Take particular care
where moisture, ice, snow, freshly cut wood or
bark may make surfaces slippery. Do not stand
on ladders or trees when using the saw.
6. Take particular care when working on sloping
ground; rolling trunks and branches pose a
potential hazard.
7. Never cut above shoulder height.
8. Hold the chain saw with both hands when
switching it on and using it. Hold the rear
handle with your right hand and the front handle
with your left. Hold the handles firmly with your
thumbs. The bar and the chain must not be in
contact with any objects when the saw is
switched on.
16. Guide the chain saw such that no part of your
body is within the extended path of the saw chain
(see figure).
006909
17. When moving around between sawing operations,
apply the chain brake in order to prevent the
chain from being operated unintentionally. Hold
the chain saw by the front handle when carrying it,
and do not keep your finger on the switch.
18. Withdraw the mains plug when taking breaks or
leaving the chain saw unattended. Leave the
chain saw where it cannot present a hazard.
Kickback
1. Hazardous kickback may arise during work with
the chain saw. Kickback arises when the tip of the
bar (in particular the upper quarter) comes into
contact with wood or another solid object. This
causes the chainsaw to be deflected in the
direction of the operator.
014316
9. Clean the area to be cut of foreign objects such
as sand, stones, nails, wire, etc. Foreign objects
damage the bar and chain, and can lead to
dangerous kickback.
10. Take particular care when cutting in the vicinity of
wire fences. Do nut cut into the fence, as the saw
may kick back.
11. Do not cut into the ground.
12. Cut pieces of wood singly, not in bunches or
stacks.
13. Avoid using the saw to cut thin branches and
roots, as these can become entangled in the
chain saw. Loss of balance presents a hazard.
14. Use a secure support (trestle) when cutting sawn
timber.
15. Do not use the chain saw to prise off or brush
away pieces of wood and other objects.
006919
2. In order to avoid kickback, observe the following:
• Never begin the cut with the tip of the bar.
• Never use the tip of the bar for cutting. Take
particular care when resuming cuts which
have already been started.
• Start the cut with the chain running.
• Always sharpen the chain correctly. In
particular, set the depth gauge to the correct
height.
• Never saw through several branches at a time.
• When limbing, take care to prevent the bar
from coming into contact with other branches.
• When bucking, keep clear of adjacent trunks.
Always observe the bar tip.
• Use a trestle.
