Only high-quality air filters should be
used, to protect the engine against
ingress of abrasive dust.
STIHL recommends the use of genuine
STIHL air filters. The high quality of
these parts will ensure troublefree
operation, a long service life for the
engine and extremely long filter life.
Engine Management
Exhaust emissions are controlled by the
design of the engine and components
(e.g. carburation, ignition, timing and
valve or port timing).
