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
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
engine 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".
