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.
⚫
Use an anti-oxidant added quality oil expressly
labeled tor 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
For model RANGER 39 (38cc displacement)
GASOLINE 35 : OIL 1
For model RANGER 46 (45cc displacement)
GASOLINE 35 : OIL 1
⚫
Exhaust emission are controlled by the fund-
amental engine parameters and components
(eq ., carburetion, ignition timing and port
timing) without addition of any major hard-
ware or the introduction of an inert material
during combustion.
⚫
These engines are certified to operate on
unleaded gasoline.
⚫
Make sure to use gasoline with a minimum octane
number
of
89RON.
⚫
If you use a gasoline of a lower octane value than
prescribed. There is a danger that the engine
temperature may rise and an engine problem
such as piston seizing may cones- quaintly occur.
⚫
Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health
and the environment.
⚫
Poor quality gasoline or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
HOW TO MIX FUEL
7. Measure out the quantities of gasoline and oil to
be mixed .
8. Put some of the gasoline into a clean, approved
fuel container.
9. Pour in all of the oil and agitate well.
10. 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.
11. Put a clear indication on the outside of the
container to avoid mixing up with gasoline or
other containers.
12. Indicate the contents on outside of container for
easy identification.
FUELING THE UNIT
4. Untwist and remove the fuel cap. Rest the cap
on a dustless place.
5. Put fuel into the fuel tank to 80% of the full
capacity.
6. Fasten the fuel cap securely and wipe up any
fuel spillage around the unit.
WARNING
4. Select bare ground for fueling.
5. Move at least 10 feet (3 meters ) away from the
fueling point before starting the engine.,
6. 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:
7. FUEL WITH NO OIL( RAW GASOLINE)-It will
cause severe damage to the internal engine
parts very quickly.
8. GASOHOL-It can cause deterioration of rubber
and/or plastic parts and disruption of engine
lubrication.
9. Oil FOR4-CYCLE
ENGINE
USE-It can cause
spark plug fouling, exhaust port blocking, or
piston ring sticking.
10. 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.
11. 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 carburetor of the composite fuel.
12. In the case of scrapping the use mixed oil
container, scrap it only at an authorized
repository site.
CHAIN OIL
Use motor oil SAE #10W-30 all year round or SAE
#30~#40 in summer and SAE #20 in winter
Pay attention to agitation
