Handling petroleum products
Utmost care is required when handling fuel. Fuel may contain substances similar
to solvents. Refuel either in a well ventilated area 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, various skin diseases
may result. In addition, allergic reactions are known to occur. Eyes can be irritated
by contact with oil, fuel etc.
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 brushcutter is a high-efficiency two-stroke engine.
It is run with a mixture of fuel and two-stroke engine oil. The engine is designed
to use unleaded regular fuel with a min. Octane value of 91 RON. If 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
performance and to protect your health and the environment, only unleaded fuel
should be used!
For engine lubrication use a two-stroke engine oil (quality grade: TC-3), which is
added to the fuel. The engine has been designed to use DOLMAR two-stroke engine
oil at mixture ratio of 25:1 to protect the environment. In addition, a long service life
and reliable operation with a minimum emission of exhaust gasses is assured. It is
absolutely essential to observe a mixture ratio of 25:1 DOLMAR 2-stroke engine oil.
Otherwise reliable function of the brushcutter cannot be guaranteed.
The correct mixture ratio:
Mix 25 parts gasoline with 1 part DOLMAR 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 in an approved can which meets or exceeds
all local code standards, then add the remaining fuel. Throughly shake
the mixture before filling it into the brushcutter 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,
the spark plugs as well as the muffler. In addition, fuel consumption
will rise and the performance will be decreased.
Refuelling
Never perform refuelling operations in a closed, unventilated area.
The engine must be switched off!
Thoroughly clean the area around the gas cap, to prevent dirt from getting into –
the fuel tank.
Unscrew the gas cap and fill the tank with fuel. –
Never fill the fuel tank to the very top. –
Securely screw on the gas cap. –
Wipe the screw plug and tank with an absorbent after refuelling! –
Allow cloths to dry and discard in a proper container.
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.
