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.
