Fonctionnement du moteur
1. Procédure de démarrage
- Assurez-vous que le moteur est placé sur une surface plane.
- Open the fuel valve (if equipped).
- Move the choke lever to the 'CHOKE' position (cold engine). For a warm engine, set to 'RUN'.
- Déplacez le levier d'accélérateur en position « RAPIDE ».
- Grasp the recoil starter handle firmly and pull slowly until resistance is felt, then pull quickly and smoothly to start the engine.
- Une fois le moteur démarré, déplacez progressivement le levier de starter en position « MARCHE » à mesure que le moteur chauffe.
2. Procédure d'arrêt
- Déplacez le levier d'accélérateur en position « LENT » ou « RALENTI ».
- Mettez l'interrupteur du moteur sur la position « ARRÊT ».
- Close the fuel valve (if equipped) for storage or extended periods of non-use.

Entretien
Regular maintenance is crucial for the longevity and performance of your engine. Always perform maintenance with the engine off and cool, and disconnect the spark plug wire to prevent accidental starting.
- Vidange: Changez l'huile moteur après les 5 premières heures de fonctionnement, puis toutes les 50 heures ou une fois par an, selon la première échéance.
- Filtre à air : Inspectez et nettoyez le filtre à air toutes les 25 heures ou plus fréquemment en milieu poussiéreux. Remplacez-le s'il est endommagé.
- Bougie d'allumage: Inspect the spark plug every 100 hours. Clean or replace as needed and ensure proper gap.
- Système d'alimentation en carburant : Drain the fuel tank and carburetor if storing the engine for more than 30 days. Use a fuel stabilizer if draining is not possible.
- Nettoyage général : Keep the engine clean from dirt and debris, especially around cooling fins and air intake areas.
