STIHL recommends using only genuine
STIHL air filters, which promote trouble-
free operation of the TS 440 and a
longer service life for its engine.

Engine Management

Exhaust emissions are controlled by the
design of the engine and components
(e.g. carburation, ignition, timing and
valve or port timing).
