13 Fueling
Use only STIHL 50:1 heavy-duty engine oil or an
equivalent quality two-stroke engine oil for the
fuel mix in models equipped with a catalytic con‐
verter.
Take care when handling gasoline. Avoid direct
contact with the skin and avoid inhaling fuel
vapour.
The canister should be kept tightly closed in
order to avoid any moisture getting into the mix‐
ture.
The fuel tank and the canister in which fuel mix is
stored should be cleaned from time to time.
12.1 Fuel mix ratio
Only mix sufficient fuel for a few days work, not
to exceed 30 days of storage. Store in approved
safety fuel-canisters only. When mixing, pour oil
into the canister first, and then add gasoline.
