WARNING – Never start the saw engine
without the bar, chain and clutch cover
(chain brake) assembled - or else the clutch can
PL
come loose and cause personal injuries.

STARTING THE ENGINE

The chain brake must be engaged when
starting the saw. Set the chain brake by
pushing the chain brake lever / hand guard
forward (towards the bar), to the brake
28
position (Fig. 12). Fill the carburetor by pushing
primer bulb (14, Fig. 2). Put the choke lever
(D, Fig. 13) in the CLOSE position. Place the
chainsaw on the ground in a stable position.
Check that the chain is free to turn and will not
come into contact with any foreign objects.
Before you start the engine, make sure 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 right hand
(Fig. 14). Pull the starter cord a few times until the
first kick over of the engine is heard. Push the
choke lever in (D, Fig. 13) to its' original position
"OPEN". 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 (2, Fig. 2) to fire the half throttle-
blocking device. Release the brake (Fig. 3).
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.
