Operating Instructions

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).

During operation
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold:
Tension is correct when chain fits snugly
against the underside of the bar and 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 – the chain may otherwise
jump off the bar.
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.

After long period of full-throttle
operation
Allow engine to run for a short while at
idle speed so that engine heat 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
retensioned it at operating
temperature during cutting work.
The chain contracts as it cools
down. If it is not slackened off, it
could damage the crankshaft and
bearings.
Storing your saw for a short period:
Wait for engine to cool down. To avoid
condensation, fill the fuel tank and keep
the machine in a dry place, well away
from sources of ignition, until you need it
again.
Storing for a long period:
See "Storing the Machine".
