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.
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

15 ENGLISH
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 nonwood
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.
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

16 ENGLISH
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
