2. SECURITY MEASURES

In order to reduce risk of injury, please observe the
safety precautions which fi gure below. Read this
manual carefully. Familiarize yourself with the controls
and learn how to use the tool correctly.
Never allow children, or people who do not understand
the instructions in the manual, to use this tool.
Prolonged use of this machine exposes the user to
vibrations which may cause the disease of "white
fi ngers" (Raynaud's phenomenon). This disease
reduces the sense of touch of the hands and the
ability to regulate temperature, creating numbness
in the fi ngers and a burning sensation. It can cause
nerve and circulation problems and even necrosis in
the hands.
High vibration levels and long periods of exposure are
the factors that contribute to white fi nger disease.
To reduce the risk of white fi nger disease need to
consider these recommendations:
• Always wear gloves
• Worrying that you always have your hands hot
• Make sure the chain is always sharp
• Make frequent breaks
• Always fi rmly hold the machine by the handles
If you fi nd some of the symptoms of white fi nger
disease see your doctor immediately.
Do not forget to give this book if you sell or lend this
machine.
2.1. UNEXPECTED REACTION FORCES WHILE

WORKING WITH THE CHAINSAW

2.1.1. KICKBACK
When the tip of the chain bar comes into
contact with an object, kickback can occur.
When the tip touches the object, this can
cause the bar to quickly move upwards
and backwards in the opposite direction,
towards the user. This reaction may cause losing
control of the tool, causing serious injury to the body.
2.1.2. PULL-FORWARD
There may be a "pull forward" when the chain stops
abruptly and get caught in the cutting area by a
foreign body that is in the wood or because user is
not cutting properly. The chain, when stops, pushing
forward the chainsaw that if the chainsaw is not
properly held against the branch or tree by claw,
produces an unexpected pull that can cause the user
to lose control of the saw , to fall forward and cause
severe injury.
To avoid this "pull-forward" to start the cut at full
throttle and always maintain machine at top speed for
cutting and support the grip of the chainsaw against
the wood to be cut.
2.1.3. PULL-BACK
If the top part of the chain and blade become
imprisoned in the wood, it can cause a back pull and
the blade could rebound backwards towards the user.
The chain when imprisoned or at a standstill and if the
machine is not properly fi xed to the wood by the claw
can cause loss of control of the machine and severe
damage to the user.
