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.
• It is recommended that those operating
chainsaws for trimming and performing height
work aided by a rope and belt harness:
– should never work alone;
– should be assisted by an operator on
the ground who has received training on
appropriate emergency procedures;
– should have received training
on secure climbing and work
positions for this type of job;
– are supplied with belt harnesses, ropes,
flat belts with end loops, clasp clips and
other recommended additional safety
equipment or any other system that prevents
the operator and chainsaw from falling.
• Perform cleaning and maintenance
before storing the machine after use.
• 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.
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
Chainsaw users should take additional
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 and do
not saw above shoulder height. This
helps avoid undesired contact with the
ends and allows for more control over the
chainsaw in unexpected situations.
• Only use the guide bar and chains
recommended by the manufacturer.
Unsuitable guides and chains can cause
the chain to break and/or kickbacks.
• Follow the manufacturer's instructions
regarding sharpening and maintenance
of the chainsaw. A decrease in the level of
depth can cause an increase in kickbacks.
• Techniques for using the electric
chainsaw (battery-operated)
Always observe the safety regulations
and use the most suitable cutting
techniques according to the work to be
performed, following the instructions and
examples in the user instructions.
• Safe carrying of the electric
chainsaw (battery-operated)
Whenever the machine is to be
handled or transported you must:
– turn off the motor, wait for the chain to stop
and unplug the machine from the mains;
– apply the protection bar cover;
– only hold the machine using the handles
and position the bar in the opposite
direction to that used during operation;
When using a vehicle to transport the machine,
position it so that it can cause no danger
to persons and fasten it firmly in place.
• Recommendations for first-time users
Before felling or delimbing for
the first time, make sure:
– to have been specifically trained
to use this type of equipment;
– to have carefully read the safety
regulations and user instructions
contained in this manual;
– you practise first on logs on the ground
or attached to trestles, in order to
get familiar with the machine and the
most suitable cutting techniques.
• Handling and correct use of
battery-operated power tools
a) Make sure that the machine is switched
off before inserting the battery. Inserting
a battery in an electric device which is
switched on can cause accidents.
b) Charge battery packs only with
the chargers recommended by the
manufacturer. Battery chargers are
generally specific for each battery type;
use with other types can cause fire risks.
