8 Mixing Fuel and Refueling the Chainsaw

8 Mixing Fuel and Refueling
the Chainsaw
8.1 Mixing fuel
The fuel required for this chainsaw is a mixture of
two-stroke engine oil and gasoline, in a mixing
ratio of 1:50.
STIHL recommends you use STIHL MotoMix.
If you mix the fuel yourself, use only STIHL two-
stroke engine oil or another high-performance
engine oil in accordance with JASO FB, JASO
FC, JASO FD, ISO-L-EGB, ISO-L-EGC or ISO-L-
EGD.
STIHL specifies STIHL HP Ultra two-stroke
engine oil or an equivalent high-performance
engine oil in order to maintain emission limits
over the machine's service life.
► Make sure that the octane number of the gas‐
oline is at least 90 RON and the ethanol con‐
tent is not more than 10% (for Brazil: 27%).
► Make sure the two-stroke engine oil you are
using meets the requirements.
► Depending on the desired amount of fuel,
determine the correct amounts of two-stroke
engine oil and gasoline in a mixing ratio of
1:50. Examples for fuel mixes:
– 20 ml Two-stroke engine oil, 1 l gasoline
– 60 ml Two-stroke engine oil, 3 l gasoline
– 100 ml Two-stroke engine oil, 5 l gasoline
► Pour two-stroke engine oil into a clean
approved fuel canister first and then add gaso‐
line.
► Thoroughly mix the fuel before topping up.
8.2 Filling up the Chainsaw with
Fuel
► Shut off the engine and engage the chain
brake.
► Allow the chainsaw to cool down.
► Place your chainsaw on a level surface so that
the fuel tank cap faces up.

► Use a suitable tool to turn the fuel tank cap
counterclockwise until it can be removed.
► Remove the fuel tank cap.
NOTICE
■ Exposure to light, direct sunlight and extreme
temperatures may accelerate fuel separation
or aging. Topping the chainsaw up with
unmixed or older fuel may damage the chain‐
saw.
► Thoroughly mix the fuel before topping up.
► Do not top up with fuel stored for more than
30 days (STIHL MotoMix: 5 years).
► When topping up, ensure that no fuel is spil‐
led and that the fuel level remains at least
15 mm under the edge of the tank.
► Fit the fuel tank cap on the tank opening.
► Use a suitable tool to turn the oil tank cap
clockwise and tighten it down firmly.
The fuel tank is closed.
