As soon as the engine runs
N Blip the throttle trigger (2) the
Master Control lever (1) moves to
the run position F and the engine
settles down to idling speed.
N Pull the hand guard back toward the
front handle.
The chain brake is now disengaged –
your saw is ready for operation.
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 the engine does not start
If you did not move the Master Control
lever from the choke shutter closed
position (l) to the starting throttle
position (n) quickly enough, the engine
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.
N Refit the spark plug – see "Spark
Plug".
N Set Master Control lever to the
starting throttle position (n) – even
if the engine is cold.
N Press in button to open the
decompression valve.
N Now start the engine.
During break-in period
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During Operation
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
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.

Operating Instructions
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see "Adjusting the
Carburetor".
Always disengage chain brake
before accelerating the engine.
Running the engine at high revs
with the chain brake engaged
(chain locked) will quickly damage
the engine and chain drive (clutch,
chain brake).
