If there is a noticeable loss of engine
power:
N Knock out the filter or blow it clear
with compressed air from the inside
outwards
If knocking-out or blowing-out does not
suffice, or in the case of stubborn dirt or
stuck filter fabric, the filter must be
subjected to a thorough cleaning.
Always replace a damaged filter.
Thorough filter cleaning
N Wash the filter in STIHL special-
purpose cleaner (special
accessory) or a clean, non-
flammable cleaning liquid (e.g.,
warm soapy water) – rinse the filter
from inside to out under a water jet
– do not use high-pressure cleaners
N Dry all filter parts – do not expose to
extreme heat
N Do not oil the filter
N Reinstall filter
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.
Basic information
The carburetor comes from the factory
with a standard setting.
The carburetor has been adjusted for
optimum performance and fuel
efficiency in all operating states.
The adjusting screws on this carburetor
can only be set within narrow limits.
The ignition module limits the maximum
speed. It is therefore not possible to
increase the maximum speed by further
turning the high speed screw (H) in the
clockwise direction (making the mix
leaner).
Standard setting
N Switch off the engine
N Check the air filter – clean or replace
it if necessary
N Check the spark arresting screen in
the muffler (present only in some
countries) – clean or replace it if
necessary
