Handling fuel
Utmost care is required when handling fuel. Fuel may contain substances similar
to solvents. Refuel either in a well-ventilated room or outdoors. Do not inhale
fuel vapors; avoid any contact of fuel or oil with your skin.
Mineral oil products degrease your skin. If your skin comes in contact with these
substances repeatedly and for an extended period of time, it will desiccate.
Various skin diseases may result. In addition, allergic reactions mey occur. Eyes
can be irritated by contact with oil. If oil comes into your eyes, immediately wash
them with clear water. If your eyes are still irritated, see a doctor immediately!
Fuel and oil mixture
The engine of the String trimmer is a high-efficiency two-stroke engine. It is run
w
ith a mixture of fuel and two-stroke engine oil. The engine is designed for
unleaded regular fuel with a min. octane value of 91 RON. In case no such fuel is
available, you can use fuel with a higher octane value. This will not affect the
engine, but may cause poor operating behaviour.
A
similar situation will arise from the use of leaded fuel. To obtain optimum
engine operation and to protect your health and the environment, only unleaded
fuel should be used!
For lubricating the engine use a two-stroke engine oil (quality grade: TC-3), which
is added to the fuel. The engine has been designed to use specified two-stroke
engine oil at mixture ratio of 50:1 to protect the environment. In addition, a long
service life and a reliable operation with a minimum emission of exhaust gases is
guaranteed. It is absolutely essential to observe a mixture ratio of 50:1 (specified
2-stroke engine oil), as otherwise reliable function of the String trimmer cannot be
guaranteed.
The correct mixture ratio:
Gasoline : Specified two-stroke engine oil = 50 : 1 or
Gasoline : Other manufacturer’s two-stroke engine oil = 25 : 1
recommended

NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of
the fuel required, then add the remaining fuel. Thoroughly shake the
mixture before filling it into the String trimmer tank. It is not wise to add
more engine oil than specified to ensure safe operation.
This will only result in a higher production of combustion residues which
will pollute the environment and clog the exhaust channel in the cylinder as
well as the muffler. In addition, the fuel consumption will rise and the
performance will decrease.
Refuelling
The engine must be switched off!
– Thoroughly clean the area around the fuel filler cap (2), to prevent dirt from
getting into the fuel tank (1).
– Unscrew the fuel filler cap (2) and fill the tank with fuel.
– Tightly screw on the fuel filler cap (2).
– Clean screw fuel filler cap (2) and tank after refueling!
