Standard Setting
► Shut off the engine.
► Check the air filter and clean or replace if nec‐
essary.
► Turn the high speed screw (H) clockwise as
far as stop, then turn it back 1 full turn.
► Turn the low speed screw (L) clockwise as far
as stop, then turn it back 1 full turn.
20.3
Adjusting Idle Speed
► Carry out standard setting.
► Start and warm up the engine.
20.3.1
Engine stops while idling
► Turn the idle speed screw (LA) clockwise until
the chain begins to run – then back it off
3/4 turn.
20.3.2
Saw chain runs while engine is idling
► Turn the idle speed screw (LA) counterclock‐
wise until the chain stops moving – then turn it
another 3/4 turn in the same direction.
WARNING
If the chain continues moving when the engine is
idling, have your saw checked and repaired by
your servicing dealer.
20.3.3
Erratic idling behavior, poor accelera‐

► Turn the low speed screw (L) slowly counter‐
clockwise until the engine runs and acceler‐
ates smoothly.
It is usually necessary to change the setting of
the idle speed screw (LA) after every correction
to the low speed screw (L).
20.4
Fine Tuning for Operation at
High Altitude
A slight correction of the setting may be neces‐
sary if the engine does not run satisfactorily:
► Carry out standard setting.
► Warm up the engine.
► Turn high speed screw (H) slightly clockwise
(leaner) – no further than stop.
NOTICE
After returning from high altitude, reset the car‐
buretor to the standard setting.
If the setting is too lean there is a risk of engine
damage due to insufficient lubrication and over‐
heating.

► If the engine is down on power, difficult to start
or runs poorly at idle speed, first check the

eroded. Install only suppressed spark plugs of
the type approved by STIHL – see "Specifica‐
tions".
