After a long period of full-throttle
operation
Allow engine to run for a while at idle
speed so that the heat in the engine 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 may
damage the gearbox and bearings.
Storing machine for a short period:
Wait for the engine to cool down. Drain
the fuel tank and store the machine in a
dry place, well away from sources of
ignition, until you need it again.
Storing for longer period:
See "Storing the Machine".
For periods of about 3 months or longer:
: Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
: If you use a biological chain and bar
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
: Store the machine in a dry, high or
locked location, out of the reach
of children and other unauthorised
persons.
: Turn the bar over –
every time you sharpen the chain –
and every time you replace the
chain – this avoids one-sided wear,
especiallly at nose and underside of
the bar.
