(e.g. carburation, ignition, timing and
valve or port timing).

M-Tronic

General Information
The M-Tronic controls fuel feed and
ignition timing electronically in all
operating conditions.
M - Tronic guarantees simple and fast
starts. The engine is started in the
Start } position irrespective of climatic
conditions or engine temperature. After
starting, the Start } position can be
maintained until the engine runs
smoothly.
M-Tronic ensures optimum engine
power at all times, very good
acceleration and automatic adjustment
to suit changing conditions.
For this reason there is no need to
change the carburetor setting – the
carburetor has no adjusting screws.
If the usual good running behavior and
engine power are not reached after an
extreme change in operating conditions,
contact your servicing dealer for
assistance.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.

Winter Operation

Preheating the carburetor
Repositioning a shutter allows heated air
to be drawn in from around the cylinder
and mixed with cold air – this helps
prevent carburetor icing.
