Operating Instructions - Stihl MS 261 Manual De Instrucciones

English
Pull the hand guard back toward the
N
front handle.
The chain brake is now disengaged –
your saw is ready for operation.
Always disengage chain brake
before accelerating the engine.
High revs with the chain brake
engaged (chain locked) will
quickly damage the clutch and
chain brake.
At very low outside temperatures:
Allow engine to warm up at part
N
throttle.
Change over to winter operation if
N
necessary – see "Winter
Operation".
Stopping the engine
Move the Master Control lever to the
N
stop position (0).
If you have moved the Master Control
lever from the starting throttle
position (n) to the stop position (0) –
press down the throttle trigger lockout
and squeeze the throttle trigger at the
same time.

If the engine does not start
If you did not move the Master Control
lever from the choke shutter closed
position (l) to the starting throttle
position (n) quickly enough, the engine
may be flooded.
Move the Master Control lever to the
N
stop position (0).
Remove the spark plug – see
N
"Spark Plug".
Dry the spark plug.
N
Crank the engine several times with
N
the starter to clear the combustion
chamber.
Refit the spark plug – see "Spark
N
Plug".
Set Master Control lever to the
N
starting throttle position (n) – even
if the engine is cold.
Press the button to open the
N
decompression valve (depending
on model).
Now start the engine.

Operating Instructions

During the 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
unnecessarily 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
shortblock are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During work
Do not make the mixture leaner to
achieve an apparent increase in
power – this could damage the
engine – see "Adjusting the
Carburetor".
Open the throttle only when the
chain brake is off. Running the
engine at high revs with the chain
brake engaged (chain locked) will
quickly damage the shortblock
and chain drive (clutch, chain
brake).
Check chain tension frequently
A new saw chain must be retensioned
more frequently than one that has been
in use already for an extended period.
