the saw chain is not contacting any object.
Never try to start the saw when the guide bar
is in a cut. Hold the front handle firmly with the
left hand and put your right foot onto the base
of the rear handle (Fig. 15). Pull the starter cord a
few times until the first kick over of the engine
is heard. Move the choke lever, (B, Fig.14B) to the
intermediate position (2). Pull the starter cord to
start the engine. Once the engine is going release
the chain brake and wait for a few seconds.
Then accelerate with the throttle (C, Fig. 13) to
fire the half throttle-blocking device.
WARNING - Once the engine is warmed up
do not use the choke to start up again.
WARNING - Use the semi-acceleration
device only in the phase of starting the
engine.
BREAKING-IN THE ENGINE
The engine reaches the maximum power after
5÷8 hours of activity.
During this period of breaking-in do not use the
engine at wide open throttle without load, to
avoid excessive functioning stress.
WARNING! - During the breaking-in
period do not vary the carburetion to
obtain a presumed power increment; the
engine can be damaged.
NOTE: It is normal for smoke to be emitted
from a new engine during and after first use.
BREAKING-IN THE CHAIN
New chains will stretch and must be tightened
frequently. Tension adjustment should only be
made when the chain is cool. First, turn the chain
and lubricate it with additional oil. Then start
the saw and allow it to run at moderate speed,
checking that the oil pump is working properly.
Stop the engine and adjust the chain tension.
Start the saw again and make a few cuts in a
trunk to heat up the chain. Stop the engine, allow
the chain to cool and adjust again. Repeat this
process until the chain retains proper tension. Do
not touch the ground with the chain.
WARNING - Never touch the chain while
the motor is running. Do not touch the
ground with the chain.
6. STOPPING THE ENGINE
Release the throttle lever (C, Fig. 12) and let the
engine return to idle. Switch off the engine,
returning the choke lever (B, Fig.13) to the fully
up position (3).
Do not put the chain saw on the ground
when the chain is still moving.
7. USE
Long term inhalation of the engine's exhaust
fumes, chain oil mist and dust from sawdust can
represent a health risk.
ICE DEVICE SYSTEM
In the event of temperatures below 0°C, move
the cursor (A, Fig.33) to the winter position. In
this way heated air from the cylinder is also taken
in, preventing thus the formation of ice inside the
carburetor.
When the temperature rises above +10°C,
move the cursor (A, Fig.34) to the summer
position. Failure to reset this parameter
could impair motor performance due to
overheating.
CHAIN BRAKE
The inertial chain brake ensures maximum
safety in using the chainsaw. It protects the
operator from dangerous kickback which can
occur during working phases. It is actuated, with
consequent instant locking of the chain, when
the operator presses the lever (manual operation)
or automatically by inertia when the protection is
pushed forward (Fig. 16) in the event of sudden
kickback (inertial operation).
The chain brake is released by pulling the lever
towards the operator (Fig. 3).
CHECKING BRAKE OPERATION
At machine inspection prior to each job, check
the operating condition of the brake following
the steps below:
1. Start the engine and grasp the handle
securely with both hands.
2. Pulling the throttle lever to maintain the chain
operation, push the brake lever down toward
the front using the back of your left hand
(Fig. 11).
3. When the brake operates and the chain is
