Using the machine
Wear appropriate clothing during
work. Your dealer can provide you
with useful information about the
best health and safety devices
to guarantee your safety when
working. Do not apply constant or
excessive pressure when gripping
the handles.
Extensive use of the chain saw ex-
poses the operator to vibrations,
which can lead to circulation issues
("white fingers"). To avoid this risk,
wear gloves and keep your hands
warm. If any symptom of "white fin-
gers" occurs, consult a physician
immediately. These symptoms in-
clude: Numbness, loss of feeling,
tingling, itching, pain, reduced mus-
cular strength, changes in the colour
or condition of the skin. Normally
these conditions affect the fingers,
hands or pulse. The risk increases
at low temperatures.
Plan your work in such a way that
the use of devices that generate
strong vibrations is spread over se-
veral days.
Using the machine for felling and pruning
trees requires special training.
WARNING!
Keep the chain saw away from all
parts of your body while working.
Do not work with the chain saw in
wind, bad weather, poor visibility,
and too low or high temperatures.
Ensure that there are no dead bran-
ches that may fall down.
Never work inside the crown of a
tree unless you have been specifi-
cally trained to do so.
Checks to carry out during work
Checking the chain tension
During work, the chain undergoes continuous
elongation, as a result of which the tension must
be checked regularly.
469850_d
During the first period of use (or after
changing the chain), the check for chain
elongation must be carried out more fre-
quently.
WARNING!
Do not work with a loose chain so as to
avoid hazardous situations that can oc-
cur if the chain slips out of its guide.
To tighten the chain tension, proceed as described
under "Preparing for work" > "Checking the chain
tension".
Checking the oil flow
CAUTION!
Do not use the machine without lubrica-
tion! The oil in the oil tank can be entirely
consumed during the time it takes to use
each fill of fuel. Make sure that you rep-
lenish the oil tank each time you refuel
the chain saw.
When checking the oil flow, make sure
that the bar and the chain are correctly
positioned.
1. Start the engine, let it run at medium speed
and check that the oil is distributed by the
chain as shown in Fig. 11.
2. The oil flow can be adjusted with a screwdri-
ver at the corresponding adjusting screw (1 or
1a) of the pump, which is found at the bottom
of the machine (Fig. 11).
Working methods and cutting techniques
Before you fell or prune a tree for the first time,
you should practice on a tree stump or a branch
set up on a stand to gain a feel for the machine
and acquire the suitable cutting techniques.
WARNING!
If the chain does not run true during work,
switch off the engine immediately.
