Fuel and oil mixture
– The engine of the Hedge Trimmer is a high-­efficiency 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 ROZ.
In case no such fuel is available, you can use fuel with a higher octane value.
This will not damage 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: TSC-­3),
which is added to the fuel.
The engine has been designed for use with MAKITA two-­stroke engine oil
and a mixture ratio of 50:1 only to protect the environment. In addition, a long
service life and a reliable operation with a minumum emission of exhaust
gases is guaranteed. It is absolutely essential to observe a mixture ratio
of 50:1 (MAKITA 2-­stroke engine oil), otherwise the reliable function of the
Hedge Trimmer cannot be guaranteed.
– The correct mixture ratio:
Gasoline: MAKITA genuine 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. In an approved can which meets of exceeds all
local code standards, then add the remaining fuel.
Thoroughly shake the mixture before filling it into the Hedge Trimmer’s
tank.
It is not wise to add more engine oil than specified to ensure safe
operation. It 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 muffler. In addition, the fuel
consumption will rise and the performance will decrease.
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.
If your skin comes in contact with these substances repeatedly and for an
extended period of time, it will desiccate.
Variouse skin diseases may result. In addition, allergic reactions are known to
occur.
Eyes can be irritated by contact with oil, fuel etc.
If oil, fuel, etc., comes into your eyes, immediately wash them with clear water.
If your eyes are still irritated, see a doctor immediately!
