QRECOMMENDED MIXING RATIO
    GASOLINE 50 : OIL 1
<when using genuine oil>

• Exhaust emission are controlled by the funda-

• These engines are certified to operate on unleaded 

gasoline.

• Make sure to use gasoline with a minimum octane 

number of 89RON (USA/Canada: 87AL).

• If you use a gasoline of a lower octane value than 

prescribed, there is a danger that the engine tem-
perature may rise and an engine problem such as 
piston seizing may consequently occur.

• Unleaded gasoline is recommended to reduce the 

contamination of the air for the sake of your health 
and the environment.

• Poor quality gasolines or oils may damage sealing 

rings, fuel lines or fuel tank of the engine.

QHOW TO MIX FUEL 

•    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. 

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 for the engine to last long. 
Be careful that, if the agitation is insufficient, there 
is an increased danger of early piston seizing due 
to abnormally lean mixture.

5. Put a clear indication on the outside of the con-

tainer to avoid mixing up with gasoline or other 
containers.

6. Indicate the contents on outside of container for 

easy identification.

QFUELING THE UNIT 
1. Untwist and remove the fuel cap. Rest the cap on 

a dustless place.

2. Put fuel into the fuel tank to 80% of the full capac-

ity.

3. Fasten the fuel cap securely and wipe up any fuel 

spillage around the unit.

1.   Select bare ground for fueling.
2.   Move at least 10 feet (3 meters) away from the fu-

eling point before starting the engine.

3. Stop the engine before refueling the unit. At that 

time, be sure to sufficiently agitate the mixed gas-
oline in the container.

QFOR 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 lubri-
cation.

3. OIL FOR 4-CYCLE ENGINE USE  – It can cause 

spark plug fouling, exhaust port blocking, or piston 
ring sticking.

4.  Mixed fuels which have been left unused for a 

period of one month or more may clog the carbu-
retor 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, activate the engine and empty the carbure-
tor of the composite fuel. 

6. In the case of scrapping the used mixed oil con-

tainer, scrap it only at an authorized repository site.

•  As for details of quality assurance, read the de-

scription 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, etc. described therein, it may not be cov-
ered by the warranty.

QFUEL

• Gasoline is very flammable. Avoid smoking or 

• The HITACHI engines are lubricated by oil specially 

formulated for air-cooled 2-cycle gasoline engine 
use. If genuine oil is not available, use an anti-
oxidant added quality oil expressly labeled for air-
cooled 2-cycle engine use(JASO FC GRADE OIL or 
ISO EGC GRADE).

• Do not use BIA or TCW (2-stroke water-cooling type) 

mixed oil.
