Gasoline is highly flammable. Avoid smoking or producing any
flame or spark near fuel. Be sure to stop the engine and allow it to
flame or spark near fuel. Be sure to stop the engine and allow it to
cool before refueling the unit. Select an open ground for refueling

YAROS engines are lubricated with an oil specially formula-
ted for use in air-cooled 2-stroke gasoline engines. If YAROS
oil is not available, use a quality oil with antioxidant ad-
ded that is expressly for use in air-cooled 2-stroke engines.
We recommend using our specific 2-stroke engine oil, to mix with
gasoline: Ref.:6000844 and Ref.:6000846.
RECOMMENDED MIXING RATIO
PETROL 25: OIL 1
(when using authentic YAROS oil)
• Exhaust emissions are controlled by critical engine parame-
ters and components (eg, carburetion, ignition and port trim)
without adding any major software or introducing an inert
material during combustion.
• These engines are certified to run on unleaded gasoline.
• Be sure to use gasoline with a minimum octane rating of 89RON
(USA/Canada: 87AL).
• If you use gasoline with an octane number lower than the pres-
cribed number, there is a danger that the engine temperature will
rise and an engine problem such as piston sticking may occur as
a result.
• Unleaded gasoline is recommended to reduce air pollution for the
sake of health and the environment.
• Poor quality gasoline or oil can damage the engine's sealing rings,
lines, or fuel tank.
HOW TO MIX THE FUEL
WARNING
• Pay attention to the agitation.
1. Measure the amounts of gasoline and oil to be mixed.
2. Put some gasoline into a clean, approved fuel tank.
3. Pour all the oil into this and shake well.
4. Pour in the rest of the gasoline and stir the mixture again for
at least one minute. Mixing some oils can be difficult, depending
on the oil ingredients, sufficient agitation is necessary to benefit
engine life. Be careful, if the agitation is insufficient, there is an
increased danger of early piston sticking due to an abnormally lean
mixture.
5. Place a clear indication or label on the outside of the tank to
prevent it from being confused with deposits of gasoline or other
substances.
6. List contents on outside of reservoir for easy identification.
UNIT SUPPLY
1. Unscrew and remove the fuel cap. Place the lid on a dust free
place.
2. Put the fuel inside the tank to 80% of the total capacity.
3. Securely attach the fuel cap and clean up any fuel spillage
around the unit.
WARNING
1. Select a bare ground for resupply.
2. Move the unit at least 3 meters away from the fueling point
before starting the engine.
3. Stop engine before refueling unit. At this time, be sure to suffi-
ciently stir the mixed gasoline in the tank.
TO CONTRIBUTE TO ENGINE LIFE, AVOID:
1. FUEL WITHOUT OIL (RAW GASOLINE) - This will quickly cause
severe damage to internal engine parts.
2. GASOHOL - This can cause the deterioration of rubber and/or
plastic parts and an alteration in the lubrication of the engine.
3. OIL FOR USE IN 4-STROKE ENGINES - This may cause spark
plug fouling, exhaust port fouling, or piston ring fouling.
4. Mixed fuels that have been left unused for a period of a
month or more can clog the carburetor and cause failure causing
the engine to malfunction.
5. In the case of product storage for a long period of time, clean
the fuel tank after emptying it. Then, start the engine and drain the
compound fuel from the carburetor.
6. In the event that you need to dispose of the mixed oil reservoir,
do so only at an authorized disposal site.
