N Wash the filter in STIHL special
cleaner (special accessory) or a
clean, non-flammable solution (e.g.
warm soapy water). Rinse the filter
from the inside outwards under a jet
of water – do not use a pressure
washer.
N Dry the filter components – do not
expose to high temperatures.
Installing the air filter
N Place the filter in position.
N Press the air filter in the direction of
the filter housing and turn it
clockwise at the same time until it
engages – the "STIHL" name must
be horizontal.
N Install the shroud – see "Shroud".
Exhaust emissions are controlled by the
design of the fundamental engine
parameters and components (e.g.
carburation, ignition, timing and valve or
port timing) without the addition of any
major hardware.
General Information
The carburetor comes from the factory
with a standard setting.
This setting provides an optimum fuel-air
mixture under most operating
conditions.
With this carburetor it is only possible to
correct the adjusting screws within fine
limits.
If the setting is too lean there is a risk of
engine damage due to insufficient
lubrication and overheating.
Standard Setting
N Stopping the engine
N Check the air filter and clean or
replace if necessary.
N Check the spark arresting screen
(country-specific) in the muffler and
clean or replace if necessary.
