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, and avoid any contact of fuel or oil with your skin.
Mineral oil products degrease your skin. Prolonged skin contact with these
products will cause your skin to become extremely dry, which may result in
various kinds of skin disease. 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 brush cutter engine is a high-efficiency two-stroke engine. It runs on 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. If for any reason no such fuel is
available, you can use fuel with a higher octane value. This will not affect the
engine, but it may cause poor operating behaviour.
Similar problems will arise from the use of leaded fuel. To obtain optimum engine
operation and to protect your health and the environment, use only unleaded
fuel!
To lubricate the engine, add two-stroke engine oil (quality grade: JASO FC or
ISO EGD) to the fuel. The engine has been designed to use the specified two-
stroke engine oil at mixture ratio of 50:1 to protect the environment.
Additionally, long service life accompanied by reliable operation and minimum
emissions are guaranteed through the use of this mixture ratio. Reliable
functioning of the brush cutter cannot be guaranteed unless this mixture ratio of
50:1 (specified 2-stroke engine oil) is strictly observed.
Correct mixture ratio:
Gasoline: Specified two-stroke engine oil = 50 : 1 or
Gasoline: Other manufacturer’s two-stroke engine oil = 25 : 1 recommended
NOTE: To prepare 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 pouring it into the brush cutter tank. To ensure safe
operation, do not add more engine oil than the specified amount. Doing
so will only result in a higher production of combustion residues which
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 the screw fuel filler cap (2) 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.
