After Finishing Work; Taking Care Of Guide Bar - Stihl MS 170 Manual De Instrucciones

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:

: Turn the bar over –
every time you sharpen the chain
and every time you replace the
chain – this helps avoid one-sided
wear, especially at the nose and
underside of the bar.
: Regularly clean
the oil inlet hole (1),
the oilway (2) and
the bar groove (3).
: Measure groove depth –
with scale on filing gauge* – in area
used most for cutting.
