Step 1 of 5: Always choose the cleanest and flattest area possible for refuelling your machine. Lay the chain saw down with the tank filler openings facing upward.

Step 2 of 5: Clean the area around the tank openings with a clean cloth.

Step 3 of 5: Open both tanks (fuel tank and chain lubricant tank) with a screwdriver or with the combination wrench.

Step 4 of 5: Fill up both tanks slowly and carefully. Fill the fuel tank with the fuel mix and the oil tank with the chain lubricant. The see-through fuel tanks on the machines allow you to check the level at a glance. And to make sure there are no spills, STIHL offers a patented filling system for fuel and chain lubricant.

Step 5 of 5: Tighten up both tank screw caps as tight as possible. This helps reduce the risk of unit vibrations causing an incorrectly tightened filler cap to loosen or come off and spill quantities of fuel. Watch out for leaks; if there is a leak of fuel do not start the engine (fire hazard, danger to life).
