• 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. RedMax Air-Cooled  "Max Life"  Synthetic blend
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 50 : OIL 1 
(when using  RedMax Air-Cooled  "Max
Life")

• 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

IMPORTANT

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.

• As for details of quality assurance, read the description in the

section Limited Warranty carefully. Moreover, normal wear and
change in product with no functional influence are not covered
by the warranty. Also, be careful that, if the usage in the
instruction manual is not observed as to the mixed gasoline,
