Fueling We recommend STIHL 50:1 two-stroke engine oil since it is specially formulated for use in STIHL engines. Do not use BIA or TCW (two-stroke water cooled) mix oils! Take care when handling gasoline. Avoid direct contact with the skin and avoid inhaling fuel vapour (see "Safety Precautions"). The canister should be kept tightly closed in order to avoid any moisture getting into the mixture. The fuel tank and the canister in which fuel mix is stored should be cleaned from time to time. Fuel mix ages: Only mix sufficient fuel for a few days work, not to exceed 3 months of storage. Store in approved safety fuel-canisters only. When mixing, pour oil into the canister first, and then add gasoline. Gasoline Oil (STIHL 50:1 or equivalent branded TC oils) US gal.

Before fueling, clean the fuel filler cap and the area around it to ensure that no dirt falls into the tank. Always thoroughly shake the mixture in the canister before fueling your machine. !Warning! In order to reduce the risk of burns or other personal injury from escaping gas vapor and fumes, remove the fuel filler cap carefully so as to allow any pressure build-up in the tank to release slowly. !Warning! After fueling, tighten fuel cap as securely as possible by hand. Use a suitable tool (e.g. screwdriver end of combination wrench) to tighten slotted fuel caps. 046 143BA008 KN 143BA009 KN Change the fuel pick up body every year.
