3.2 Fueling and Oiling
This chainsaw operates on a gasoline-oil mixture (2-stroke engine) and requires bar and chain oil for lubrication.

- Activeu el fre de cadena empenyent el protector de mà davanter cap endavant.
- Set the choke and primer bulb according to the engine's starting procedure (refer to the engine manual for specific steps).
- Estireu fermament el cordó d'arrencada fins que el motor s'encengui.
- Once the engine starts, disengage the choke and allow the engine to warm up before use.
4.2 Tècniques de tall

5. Manteniment
Regular maintenance ensures optimal performance and extends the life of your chainsaw. Always disconnect the spark plug wire before performing any maintenance.
- Tensió de la cadena: Adjust chain tension regularly using the side-access chain tensioner for quick and easy adjustments. A properly tensioned chain should be snug but still allow you to pull it around the guide bar by hand.
- Filtre d'aire: The chainsaw features a top-mounted tool-less air filter for easy access. Clean or replace the air filter as needed to maintain engine performance and prevent debris from entering the engine.
- Bujía: Inspeccioneu i netegeu la bugia periòdicament. Substituïu-la si està desgastada o bruta.
- Barra de guia: Netegeu la ranura i els forats d'oli de la barra guia. Gireu la barra guia periòdicament per assegurar-vos que es desgasti uniformement.
- Afilat de cadena: Keep the saw chain sharp. A dull chain increases effort, reduces cutting efficiency, and can lead to kickback.
- Neteja general: Clean the exterior of the chainsaw after each use, removing sawdust, oil, and debris.
