FUELS/REFUELLING

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 may 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 brush cutter is a high-efficiency two-stroke engine. It is run
with 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 behavior.
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 brush cutter 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 brush cutter 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 refuelling.
Storage of Fuel
Fuel cannot be stored for an unlimited period of time.
Purchase only the quantity required for a 4 week operating period. Only use
approved fuel storage containers.
Observe the Safety Instructions on page 4.
