How to use

Refuel the saw with a pre-mixed petrol and 2-stroke oil at a 40:1 ratio into the 550 ml fuel tank and fill the 260 ml chain oil reservoir separately. Start the engine following the manufacturer’s standard choke and pull-start procedure, allow it to reach idle, and inspect chain lubrication before cutting. Use the side screws to set chain tension so the chain moves freely but has no sag on the guide bar. Operate the saw at recommended engine speeds, and engage the clutch only when the engine reaches the specified engagement rpm.
