How to use
Before use, prepare the correct fuel–oil mixture as specified by the engine manufacturer, fill the fuel tank, and check chain tension and lubrication. Start the engine using the choke and starter assembly on a firm surface following the tool’s starting procedure. Position both hands on the handles, engage full control before cutting, and use steady feed pressure while keeping the guide bar aligned with the cut. After each session, stop the engine, allow it to cool, clean sawdust from the chain and sprocket area, and inspect chain tension and sharpness.
Usage recommendations
Use appropriate personal protective equipment such as gloves, eye and hearing protection and chainsaw chaps. Maintain proper chain tension and bar lubrication, keep the air filter clean, and perform periodic service on the spark plug and carburettor to ensure consistent performance and longevity.
