• FUEL
Gasoline is very flamma-
ble. 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 fuel-
ing point before starting the engine.
• The engines are lubricated by oil specially for-
mulated for air-cooled 2-cycle gasoline engine
use. Use an anti-oxidant added quality oil
expressly labeled for air-cooled 2-cycle engine
use (JASO FC GRADE OIL or ISO EGC GRA-
DE).
• Do not use BIA or TCW (2-stroke water-cool-
ing type) mixed oil.
• RECOMMENDED MIXING RATIO
GASOLINE 50: OIL 1
WARNING!
• Exhaust emission are controlled by the funda-
mental engine parameters and components
(eq., carburation, ignition timing and port tim-
ing) without addition of any major hardware 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 (USA/Canada:
87AL).
• 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 conse-
quently 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 en-
gine.
• HOW 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

8. Tighten the tensioner screw.
A new chain will expand its
length in the beginning of use. Check and read-
just the tension frequently as a loose chain can
easily derail or cause rapid wear of itself and the
guide bar.
