– too high fuel consumption.
Clean the air filter every 50 operating hours, or more frequently
in dusty environments. (Every 10 hours)

Paper filter: To remove the dirt, tap the filter several times
against a hard surface. You can also blow clean
the filter from top to bottom using compressed air
(max. 2 bar).
Foam filter: Wash the air filter in warm soap water. Rinse well.
Squeeze the air filter in a dry and clean cloth.
Allow the air filter to dry well. Dip the filter into
engine oil and then squeeze it in a dry and clean
cloth to remove surplus oil. The engine smokes if
the foam contains too much excess oil.
