During Break-in Period
During Operation
After Finishing Work
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.
Check chain tension frequently.
A new chain has to be retensioned more
often than one that has been in use for
some time.
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.
Chain cold:
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.
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 -
Before storing your saw
for a long period -
•
see section "Tensioning the Saw Chain".
Drain and clean the fuel tank
•
Run engine until carburetor is dry
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.
Do not make the mixture leaner to
achieve an apparent increase in
power - this could damage the engine
Storing the Machine
-
see section "Adjusting Carburetor".
Retension the chain -
Note: Always disengage chain brake
before accelerating engine and before
starting cutting work. High revs with the
chain brake engaged (chain locked) will
quickly damage the powerhead and
chain drive (clutch, chain brake).
see section "Tensioning the Saw Chain".
For periods of about 3 months or longer:
Always slacken off the chain after
finishing work.

of full-throttle operation
•
Allow engine to run for a short while
at idling speed so that engine heat can
be dissipated by flow of cooling air.
This protects engine-mounted compo-
nents (ignition, carburetor) from thermal
overload.
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.
