exposed metal parts of the power tool "live" and
could give the operator an electric shock.
• Always wear safety goggles and ear
protection. Other protective equipment
for the head, hands and feet is also
recommended. The wearing of protective
clothing will reduce accidents caused by hurled
workpieces and accidental contact with the
toothed chain.
• Do not use chainsaws when positioned on
a tree. Starting a chainsaw when positioned on
a tree can cause body injuries.
• Keep proper footing and balance at all
times, and only use the chainsaw on fixed,
secure and flat surfaces. Slippery or unstable
surfaces such as ladders, can cause loss of
balance or control of the chainsaw.
• When cutting a branch that is under tension,
be alert for spring back. When the tension
of the wood fibres is released, the branch can
spring back and injure the operator and/or kick
the chainsaw out of control.
• Use extreme caution when cutting small
size brush and saplings. The slender material
may catch in the chainsaw and be whipped
towards you and/or pull you off balance.
• Carry the chainsaw by the front grip when
it is switched off and keep it away from
your body. When storing or transporting a
chainsaw always use the guide bar cover.
Correct handling of the chainsaw will reduce
the probability of unintended contact with the
moving chain.
• Follow the instructions
lubrication, chain tension and replacement
parts. Chains with incorrect tension and
lubrication can break and increase the risk of
kickback.
• Keep handles dry, clean and free from
oil and grease. Greasy and oily handles
are slippery and can cause loss of control.
• Use the chainsaw to cut wood only. Do not
use the chainsaw for purposes for which
it is not intended. For example: do not use
an chainsaw for cutting plastic, masonry
or other non-wood materials. Using the
chainsaw for operations other than those
intended could result in a hazardous situation.
• Local regulations may restrict
the age of the operator.
DANGER
Prolonged exposure to vibrations can cause
injuries and neurovascular
called "Raynaud's syndrome" or "white finger"),
especially to people suffering from circulation
disorders. The symptoms can appear in the hands,
wrists and fingers and are shown through loss of

of or structural changes to the skin. These effects
can be worsened by low ambient temperatures
and/or by gripping the hand grips excessively
tightly. If the symptoms occur, the length of time
the machine is used must be reduced and a
doctor consulted.
• Take breaks and change your working
position regularly.
• Improper maintenance, use of non-compliant
spare parts or modification of the safety devices
can cause damage to the device and cause
serious injury to the user.
• Perform cleaning and maintenance before
storing the machine after use.
• If the machine has been hit or dropped, make
sure it is in good condition before starting it up.
• Remove branches in sections.
• Pay attention to the branches that, once cut,
can hit the user and to those that, fallen on the
ground, can suffer a kickback.
2.3 CAUSES OF KICKBACK AND
OPERATOR PROTECTION
Kickback can occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the chain in the cut.
Contact of the tip can, in certain cases, cause a
sudden fast reverse action, pushing the guide bar
upwards and backwards towards the operator.
Pinching of the chain along the top of the guide
bar can rapidly push the chain back towards the
operator.
Both the above reactions may cause loss of
control of the saw, which could result in serious
injury for operators. Do not rely exclusively on the
chainsaw built-in safety devices

precautions to eliminate accident or injury risks
during cutting operations. Kickback is the result
of poor use of the tool and/or incorrect operating
procedures or conditions and can be avoided by
taking the specific precautions provided below:
• Hold the saw firmly with both hands,
with the thumbs and fingers around the
chainsaw grips, and position your body
and arms so that you can resist the force
of a kickback. Kickback can be controlled by
the operator if all appropriate precautions have
been taken. Do not allow the chainsaw to start.
• Do not fully extend the arms. This helps avoid
undesired contact with the ends and allows for
more control over the chainsaw in unexpected
situations.
