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 pruner saw user, you should take several
steps to keep your cutting jobs free from accident
or injury.
Kickback is the result of pruner saw misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
a) Maintain a firm grip, with thumbs and
fingers encircling the pruner 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 pruner saw.
b) Do not overreach and do not cut above
shoulder height. This helps prevent unintended
tip contact and enables better control of the pruner
saw in unexpected situations.
c) Only use replacement guide bars and
saw chains specified by the manufacturer.
Incorrect replacement guide bars and saw chains
may cause chain breakage and/or kickback.
d) Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback
• 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.
c) Use only batteries specifically designed for
your power tool. The use of other batteries
may cause injuries and fire risks.
d) Keep all unused batteries at a distance
from paper clips, coins, keys, nails, screws
or other small metal objects as contact with
the same can cause short circuits. Short
circuits between battery contacts can lead
to explosion or fires.
e) Batteries in poor condition can cause
liquids to leak. Avoid contact with the liquid.
In the case of accidental contact flush with
water. If the liquid comes into contact with
the eyes, also seek medical advice. Liquid
leaking from the battery may cause skin
irritation or burns.
f) Check that the accumulator is in good
condition and there are no signs of damage.
Do not use the device with a damaged or
worn accumulator.
2.4 BATTERY / BATTERY CHARGER
ATTENTION
The following safety rules complement the
safety rules contained in the battery charger
manual.
• Only use battery chargers recommended by
the manufacturer to recharge batteries. An
inadequate battery charger may cause electric
shock, overheating or corrosive liquid to leak
from the battery.
