Regular maintenance ensures the longevity and optimal performance of your lawn mower. Always turn off the engine and disconnect the spark plug wire before any maintenance.

6.1 Reinigung

Start the engine briefly and engage the blade to allow water to clean the underside of the deck. Turn off the engine and disconnect the hose once clean.

Figure 6.1: Easy Clean - Cleaning function with water connection.

Allgemeine Reinigung: After each use, clean grass clippings and debris from the mower deck, engine cooling fins, and wheels. Use a brush or compressed air. Do not use high-pressure washers directly on the engine or electrical components.

6.2 Motoröl prüfen und wechseln

Check the engine oil level before each use. Change the engine oil after the first 5 hours of operation, and then every 25 hours or annually, whichever comes first. Refer to the engine manual for detailed instructions on oil change procedures.

6.3 Luftfilter

Inspect the air filter regularly and clean or replace it as needed. A dirty air filter can reduce engine performance and increase fuel consumption.

6.4 Zündkerze

Inspect the spark plug annually or every 50 hours. Clean or replace it if it is fouled or worn. Ensure the correct gap is maintained.

6.5 Wartung der Klinge

Regularly inspect the cutting blade for sharpness and damage. A dull blade can tear grass, leading to an unhealthy lawn. Have the blade sharpened or replaced by a qualified service technician if necessary. Always wear heavy-duty gloves when handling the blade.
