Stop the engine and turn the H and L screws until they both stop. Do not apply excessive
force! Then, turn the screws back within the range below:
Start the engine and allow it to worm up by pulling out the throttle lever (i.e. at low speed).
Turn the L screw slowly clockwise up to the point where the idle speed reaches its maximum.
Then, turn the screw head back counterclockwise by a quarter of turn (¼) .
Turn the idle speed adjustment screw (T) counterclockwise until the chain stops. If the idle
speed is too low, turn the screw clockwise.
Perform a test cut and set the „H" screw to an optimum performance, not to a maximum
speed.

Carburettor anti-freeze device
When operating the saw at temperatures of 0 to 5 °C and high humidity, ice may form inside
the carburettor. This leads to performance reduction or irregular machine running. Thus,
installing a dedicated accessory allows the saw to heat up the air fed from the right of the
cylinder head to prevent ice formation. Under normal conditions, the saw operates in default
mode, i.e. the one used right at the time of purchase. If ice formation occurs, the saw must be
switched to the anti-freeze mode before use (fig. 17).
Chain brake
This saw incorporates an automatic brake to stop the chain rotation after a kickback occurs
during cutting operation. The brake activates automatically by inertial force acting on the
weight located under the front cover. This brake can be also operated manually by lowering
the front protective frame towards the bar (fig. 18)
Lifting the front protective frame until a click is heard will release the brake again.
CAUTION! Before each use, check the chain brake correct function by following the
procedure below.
Turn the engine off.
Hold the saw horizontally, release your hand from the front handle and catch the front of the
bar on a stub or a wood chunk. The brake must engage. The braking intensity varies with the
bar length (fig. 1 9). If the brake fails to operate, please have the saw repaired by an authorized
service. If the brake has engaged but the engine is still running at high speed, the clutch will
overheat and be damaged. If the brake engages during operation, release the throttle lever to
turn the engine off immediately
