4.3 Mowing Functions (4INONE)

• Mowing with Collection: Attach the grass collector. The MaxAirflow technology ensures optimal filling of the 60-liter collector.
• Mulching: Remove the grass collector and insert the mulching plug into the discharge opening. The lawnmower will finely chop the grass clippings and return them to the lawn as natural fertilizer.
• Side Discharge: Remove the grass collector and mulching plug. Attach the side discharge chute. This function is useful for taller grass where collection or mulching is not desired.

Regular maintenance ensures the longevity and optimal performance of your lawnmower.

• Clean the grass collector regularly.

5.2 Engine Maintenance

• Oil Change: Change the engine oil after the first 5 operating hours, then every 25 operating hours or annually.
