► Press down the trigger lockout and blip the
throttle trigger (2) – the Master Control
lever (1) moves to the run position F and the
engine settles down to idling speed.
► Pull the hand guard toward the handlebar to
disengage the chain brake.
NOTICE
Open the throttle only when the chain brake is
off. Increased engine speeds with the chain
brake on (saw chain is stationary) will quickly
damage the clutch and chain brake.
► After a cold start, warm up the engine at vary‐
ing speeds – your saw is ready for operation.
15.10 At Very Low Outside Tempera‐
tures
In case of erratic idling behaviour or poor accel‐
eration
► Readjust carburetor if necessary, see "Adjust‐
ing the Carburetor".
► If your saw is very cold (frost or ice on
machine), start the engine and keep it at a
high idle speed (with chain brake disengaged)
until it reaches normal operating temperature.
