SAFETY WARNINGS
General power tool safety warnings
WARNING: 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.
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.
Cordless 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. A moment of
inattention 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 top 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.
NOTE: The declared noise emission value(s) may
also be used in a preliminary assessment of
exposure.

15 ENGLISH
3. Hold the power tool by insulated gripping
surfaces only, because the saw chain may
contact hidden wiring. 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. Always keep proper footing.
6. 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.
7. 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.
8. 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.
9. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
10. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
11. 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.
12. Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the
guidebar 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.
►Fig.1
•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
sharpeningand maintenance
instructions for the saw chain. Decreasing
the depth gauge height can lead to increased
kickback.
13. 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.
14. Do not start the chain saw with the chain cover
being installed on it. Starting the chain saw with
the chain cover being installed on it may cause the
chain cover to thrown out forward resulting in
personal injury and damage
to objects around the
operator.
Additional Safety Warnings:
1. When using the tool with battery adapter, be
careful not to trip over the cord during
operation.
2. When using the tool with battery adapter,
keep the cord away from obstacles such as a
workpiece and branches during operation.
The cord caught by obstacles may
cause serious injury.

16 ENGLISH
Top handle chainsaw specific safety
warnings
1. This chain saw is designed especially for tree
care and surgery. The chain saw is intended to
be used by properly trained persons only.
Observe all instructions, procedures and
recommendations from the relevant
professional organization. Otherwise fatal
accidents may occur. It is recommend that
always using a rising platform (cherry picker,
lift) for sawing in trees. Rappelling techniques
are extremely dangerous and require special
training. The operators must be trained to
become familiar with safety equipment usage
and climbing techniques. Always use the
appropriate belts, ropes and carabiners when
working in trees. Always use restraining
equipment for both the operator and the saw.
2. Perform cleaning and maintenance before
storage in accordance with the instruction
manual.
3. Ensure safe positioning of the chain saw
during car transportation to avoid fuel or chain
oil leakage, damage to the tool and personal
injury.
4. Regularly check the functionality of chain
brake.
5. Do not fill the chain oil near fire. Never smoke
when you fill the chain oil.
6. National regulation may restrict the use of the
chain saw.
7. If the equipment gets heavy impact or fall,
check the condition before continuing work.
Check the controls and safety devices for

11. Take into account the direction and speed of
the wind. Avoid sawdust and chain oil mist.
Protective equipment
1. In order to avoid head, eye, hand or foot
injuries as well as to protect your hearing the
following protective equipment must be used
during operation of the chain saw:
—
The kind of clothing should be appropriate, i.
e. it should
be tight-fitting but
not be a
hindrance. Do not
wear jewelry or
clothing which could become
entangled with bushes or shrubs. If you
have long hair, always wear a hairnet!
—
It is necessary to wear a protective helmet
whenever working with the chain saw. The
protective helmet is to be checked in regular
intervals for damage and is to be replaced
after 5 years at the latest. Use only approved
protective helmets.
—The face shield of the protective helmet (or
the goggles) protects against sawdust and
wood chips. During operation of the chain
saw always wear a goggle or a face shield to
prevent eye injuries.
—Wear adequate noise protection
equipment (ear muffs, ear plugs, etc.)
—The protective jacket consists of 22 layers
of nylon and protects the operator against
cuts. It is always to be worn when working
from elevated platforms (cherry pickers, lifts),
from platforms mounted on ladders or when
climbing with ropes.
—The protective brace and bib overall is
made of a nylon fabric with 22 layers and
protects against cuts. We strongly
recommend its use.
—Protective gloves made of thick leather are
part of the prescribed equipment and must
always be worn during operation of the chain
saw.
—During operation of the chain saw safety
shoes or safety bootsfitted with
anti skid sole, steel toe caps
and protection for the leg must always to be
worn. Safety shoes equipped with a
protective layer provide protection against
cuts and ensure a secure footing. For
working in trees the safety boots must be
suitable for climbing techniques.
Vibration
1. Individuals with poor circulation who are exposed
to excessive vibration may
experienceinjury to blood
vessels or the nervous system. Vibration may
cause the following symptoms to occur in the
fingers, hands or wrists:
“Falling asleep” (numbness), tingling,
pain, stabbing sensation, alteration of skin colour
or of the skin. If any of these symptoms occur,
see a physician! To reduce the risk of “white
finger disease”, keep your
hands warm during operation and
well maintain the equipment and accessories.
