Operating Instructions
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".
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.
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.

The chain stretches and begins to sag.
The drive links must not come out of the

Crank the engine several times with
the starter to clear the combustion
chamber.
The chain contracts as it cools
down. If it is not slackened off, it
can damage the crankshaft and
bearings.

Refit the spark plug – see "Spark

Set Master Control lever to the
starting throttle position (n) – even
if the engine is cold.
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see "Adjusting the
Carburetor".
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,

Slacken off the chain if you have
retensioned it at operating
temperature 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 slacken off the chain again
after finishing work. The chain
contracts as it cools down. If it is
not slackened off, it can damage
the crankshaft and bearings.
