Two-stroke oil

• For best results and performance use Zenoah two-
stroke oil, which is specially formulated for our two-
stroke engines. Mixture 1:50 (2%).
• If Zenoah two-stroke oil is not available, use a
different two-stroke oil of good quality that is
formulated for air-cooled engines. Consult your
servicing dealer when you select an oil.
• Do not use two-stroke oil for water-cooled outboard
engines, also referred to as outboard oil.
• Do not use oil intended for four-stroke engines.

To mix gasoline and two-stroke oil

CAUTION: There is a risk that small errors
influence the ratio of the mixture drastically
when you mix small quantities of fuel.
Carefully measure the quantity of oil to be
mixed to make sure that you get the correct
mixture.
1. Fill half the quantity of the gasoline to be used.
2. Add the full quantity of oil and mix (shake) the fuel
mixture.
3. Add the remaining quantity of gasoline.
4. Carefully mix (shake) the fuel mixture and fill the fuel
tank of the product.
5. Empty and clean the fuel tank if you do not use the
product for some time.
Note: Do not mix fuel for more than 1 month at a time.

Chain oil

All Zenoah chainsaws have an automatic chain
lubrication system. On some models the oil flow is also
adjustable.
Chain oil must show good adherence to the saw chain
and also keep its flow quality during warm summer and
cold winter weather.
Use Zenoah chain oil for maximum saw chain life and to
minimise environmental damage. This chain oil has a
vegetable oil base and is also biodegradable. If this
chain oil is not available, we recommend you to use a
standard chain oil.

Use an oil of the right grade (suitable viscosity
range) to agree with the air temperature. If the oil is
too thin, it will run out before the fuel. In
temperatures below 0°C (32°F) some oils become
too thick. This can cause the oil pump to overload
and result in damage to the oil pump components.
Adjust the carburetor as recommended. A lean
mixture causes the chain oil tank to empty before the
fuel tank.
Use the recommended cutting equipment. A guide
bar that is too long will use more chain oil.
WARNING: Do not use waste oil. Waste oil
can cause injury to you and the
environment. Waste oil also causes damage
to the oil pump, the guide bar and the saw
chain.
WARNING: If the lubrication of the cutting
equipment is not sufficient, it can cause the
saw chain to break. This can cause serious
injury or death to the operator.
