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.
Move the Master Control lever to the
N
stop position (0).
Remove the spark plug – see
N
"Spark Plug".
Dry the spark plug.
N
Crank the engine several times with
N
the starter to clear the combustion
chamber.
Refit the spark plug – see "Spark
N
Plug".
Set Master Control lever to the
N
starting throttle position (n) – even
if the engine is cold.
Press the button to open the
N
decompression valve.
Now start the engine.

Operating Instructions
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
NOTICE
Do not make the mixture leaner to
achieve an apparent increase in power –
this could damage the engine – see
"Adjusting the Carburetor".
NOTICE
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).
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.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
but can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove on the underside of the bar –
the chain may otherwise jump off the
bar. Retension the chain – see
"Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
crankshaft and bearings.
After a long period of full-throttle
operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the
engine can be dissipated by flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After finishing work
Slacken off the chain if you have
N
retensioned it at operating
temperature during work.
