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”.
Shut off the engine
N
Move the Master Control lever to the
stop position (
0
).
N
Change over to winter operation if
necessary – see “Winter
Operation”.
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 the button to open the
decompression valve (depending
on model).
N
Now start the engine.
During the 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
unnecessarily 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
shortblock are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During work
Check chain tension frequently
A new saw chain must be retensioned
more frequently than one that has been
in use already for an extended period.
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".
Open the throttle only when the
chain brake is off. Running the
engine at high revs with the chain
brake engaged (chain locked) will
quickly damage the shortblock
and chain drive (clutch, chain
brake).
