FUELS/REFUELING
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 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 for use with
specified two-stroke engine oil and a mixture ratio of only 25:1 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 25:1 (specified 2-stroke engine oil), as otherwise
reliable function of the brush cutter cannot be guaranteed.
The correct mixture ratio:
Mix 25 parts gasoline with 1 part specified 2-stroke engine oil (see table on
right).
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.
The engine must be switched off.
– Thoroughly clean the area around the fuel filler cap, to prevent dirt from
getting into the fuel tank.
– Unscrew the fuel filler cap and fill the tank with fuel.
– Tightly screw on the fuel filler cap.
– Clean screw fuel filler cap and tank after refueling.
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.
