100 Cleaning/Changing the air filter
2. Air filter cartridge (paper cartridge)
• The air filter cartridge (2) filters the intake air through fine paper filter lamella.
Thus never wash out the cartridge. Clean the air filter cartridge (2) once a
week.
• Expand the lamella of the air filter cartridge (2) slightly, lay it on a clean pad
and carefully tap against it.
• Replace the air filter cartridge (2) after every 100 hours of operation. Replace
it immediately if you notice a drop in power, a drop in engine speed or smoke
in the exhaust fumes.
CAUTION
Never clean the air filter with compressed air! Compressed air destroys the filter
material and reduces the filtering capacity for fine dirt particles considerably!
Replace a damaged air filter immediately! Torn pieces of fabric and large dirt
particles can destroy the engine.
