M-Tronic
General Information
The M-Tronic controls fuel feed and
ignition timing electronically in all
operating conditions.
M-Tronic ensures simple, fast starts,
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.
