7.1 Mixing Fuel
This water pump requires a fuel mixture of gasoline and two-
stroke engine oil in a ratio of 50:1.
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 throughout the machine’s service life.
► Make sure that the octane number of the gasoline is at
least 90 RON and the ethanol content is not more than
10%.
► Make sure the two-stroke engine oil you are using meets
the requirements.
► Depending on the required amount of fuel, determine the
correct amounts of two-stroke engine oil and gasoline in a
mix ratio of 50:1. Examples for fuel mixes:
– 1 liter gasoline, 20 ml two-stroke engine oil
– 3 liters gasoline, 60 ml two-stroke engine oil
– 5 liters gasoline, 100 ml two-stroke engine oil
► Pour two-stroke engine oil into a clean approved fuel
canister first and then add gasoline.
► Thoroughly mix the fuel.
7.2 Refuelng the Water Pump
► Shut off the engine.
► Place your water pump on a level surface so that the fuel
tank cap faces up.
► Use a damp cloth to clean the tank cap and the area
around it.
