performance, increase fuel consumption
and make the machine more difficult to
start.

in the direction of the arrow and
remove the carburetor box cover

If there is a noticeable loss of engine
power:

suffice, or in the case of stubborn dirt or
stuck filter fabric, the filter must be
subjected to a thorough cleaning.
Always replace a damaged filter.

warm soapy water) – rinse the filter
from inside to out under a water jet
– do not use high-pressure cleaners

extreme heat
