Choke shutter closed (l)
– If the engine is cold (also use this
position if the engine stopped when
you opened the throttle after
starting)
Starting throttle position (n)
– If the engine is warm, i.e. if it has
been running for about one minute.
N Hold and start your saw as
described.
When Engine Begins to Fire

the starting throttle position (n).
N Hold and start your saw as

As Soon as Engine Runs
N Press down the trigger lockout and
blip the throttle trigger (3) – the
Master Control lever (4) moves to
the run position (F) and the engine
settles down to idling speed.
NOTICE
As the chain brake is still engaged, the
engine must be returned to idling speed
immediately – or the engine housing and
chain brake might otherwise be
damaged.
N Pull the hand guard back toward the
front handle.
The chain brake is now disengaged –
your saw is ready for operation.
NOTICE
Always disengage chain brake before
accelerating the engine. High revs with
the chain brake engaged (chain locked)
will quickly damage the clutch and chain
brake.
At very low outside temperatures
N Allow engine to warm up at part
throttle.
N Change over to winter operation if
necessary – see “Winter Operation”.
Shutting Off the Engine
N Move the Master Control lever to the
stop position (0).
If Engine Does Not Start
If you did not move the Master Control
lever from the choke closed
position (l) to the starting throttle
position (n) quickly enough after the
engine began to fire, the combustion
chamber may be flooded.
N Move the Master Control lever to the
stop position (0).
N Remove the spark plug – see
"Spark Plug".
N Dry the spark plug.
N Crank the engine several times with
the starter to clear the combustion
chamber.
