FUEL
WARNING
• Gasoline is very flammable. Avoid smoking or
bringing any flame or sparks near fuel. Make
sure to stop the engine and allow it cool before
refueling the unit. Select outdoor bare ground for
fueling and move at least 3 m (10 ft) away from
the fueling point before starting the engine.
• 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.
RECOMMENDED MIXING RATIO
GASOLINE 50 : OIL 1
<when using genuine oil>
• Exhaust emission are controlled by the funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing)
without addition of any major hardware or the
introduction of an inert material during com-
bustion.
• 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.
HOW TO MIX FUEL
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.
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.
FUELING 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.
WARNING
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.
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 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.
