IMPORTANT
Gasoline/Oil mixture Storage Recommendations
Store your gasoline or gasoline/oil mixture in a cool dry area in
a tightly sealed approved container to limit the entry of moisture
and additional air (oxygen). Moisture and air cause the
development of varnish and gum, making the fuel stale. Stored
gasoline and gasoline/oil mixture ages and loses its octane
rating and volatility. Do not mix more gasoline/oil than you
intend to use in 30 days, and 60 days when fuel stabilizer is
added. Premium two-stroke engine oil "Contains fuel stabilizer" and
will automatically extend your gasoline/oil mixture life up to 60
days.
HOW TO MIX FUEL
RECOMMENDED MIXING RATIO
GASOLINE 25 : OIL 1
Mix a regular gasoline(leaded or unleaded,
Alcohol-free) and a quality-proven motor
Oil for air cooled 2 cycle engines.
25:1 MIXING CHART
GASOLINE liter 0.5
2-CYCLE OIL ml
WARNING
Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be mixed.
2. Put some of the gasoline into a clean, approved fuel container.
3. Pour in all of the oil and agitate well for 10seconds.
4. Pour in the rest of gasoline and agitate again for at least one
minute. As some oils may be difficult to agitate depending on oil
ingredients, sufficient agitation is necessary. Be careful that, if
the agitation is insufficient, there is an increased danger of early
piston seizure due to abnormally lean mixture.
5. Place a clear indication on the outside of the container to avoid
mixing up with gasoline or other containers that dont contain oil.
6. Indicate the contents on outside of container for easy
identification.
FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap on a clean
surface.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel spillage
around the unit.

WARNING
1. Select flat and bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the
fueling point before starting the engine.
3. Stop the engine before refueling the unit. At that
time, be sure to sufficiently agitate the mixed
gasoline in the container.
FOR YOUR ENGINE LIFE, AVOID
1. FUEL WITH NO OIL (RAW GASOLINE) – It will
cause severe damage to the internal engine parts
very quickly.
2. GASOHOL – It can cause deterioration of rubber
and/or plastic parts and disruption of engine
lubrication.
3. OIL FOR 4-CYCLE ENGINE USE – It can cause
spark plug fouling, exhaust port blocking, or piston
ring seizure.
4. Mixed fuels which have been left unused for a
period of one month or more may clog the
carburetor and result in the engine failing to
operate properly.
5. In the case of storing the product for a long
period of time, clean the fuel tank after rendering
it empty. Next, Start the engine and run the
carburetor dry residual fuel.
6. In the case of scrapping the used mixed oil
container, scrap it only at an authorized depository
site.
