Engine Running Behavior; Lubricating The Gearbox; Storing The Machine - Stihl BT 131 Manual De Instrucciones

Engine Running Behavior

If engine running behavior is still
unsatisfactory after the air filter has been
serviced and the carburetor and throttle
cable have been adjusted correctly, the
cause may also be in the muffler.
Have the muffler checked for
contamination (coking) by a servicing
dealer!
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers.
