Stihl 44

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 section "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 section "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 compo-
nents (ignition, carburetor) from thermal
overload.

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.
Before storing your saw
for a long period -

See chapter "Storing the Machine".
During Operation After Finishing Work Storing the Machine
For periods of about 3 months or longer:
•
••
•
Drain and clean the fuel tank in a
well ventilated area.
•
••
•
Run engine until carburetor is dry -
this helps prevent the carburetor
diaphragms sticking together.
•
••
•
Remove the saw chain and guide
bar, clean them and protect
with corrosion inhibiting oil.
•
••
•
Thoroughly clean the machine -
pay special attention to the
cylinder fins and air filter.
•
••
•
If you use a biological chain lubri-
cant (e.g. STIHL Bioplus), fill the
chain oil tank.
•
••
•
Store the machine in a dry and high
or locked location - out of the
reach of children and other
unauthorized persons.
