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.
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 the chain brake
before opening the throttle. Running
the engine at higher revs with the
chain brake engaged (saw chain at
a standstill) will quickly damage the
engine and chain drive (clutch,

Retension the chain – see “Tensioning
the Saw Chain”!
Always slacken off the chain after
finishing work. The chain contracts
as it cools down. If it is not
slackened off, it can damage the
crankshaft and bearings.
