► Synthetic fabric filter: For use in severe condi‐
tions, e.g. extreme wintry operating conditions
- such as powdery or drifting snow. Less suita‐
ble for very dusty conditions.
STIHL filters have a long service life in dry oper‐
ating conditions.
► Always use STIHL filters in dry state.
Dirty air filters reduce engine power, increase
fuel consumption and make starting more diffi‐
cult.

During operation the chain saw automatically
adjusts to the optimum power.
Depending on the STIHL M‑Tronic version the
chain saw can be adjusted more quickly to the
optimum power in two different ways:
–
“Speeding up automatic adaptation of the
chain saw”
–
“Calibrating the chain saw”
