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.
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see “Adjusting
Carburetor”.
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,
chain brake).
