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 10ft (3m) away
from the fueling point before
starting the engine.

• The engines are lubricated by oil
specially formulated for air-cooled
2-cycle gasoline engine use. If
Jonsered 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.

• These engines are certified to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 89 RON (USA/Canada: 87AL)
• If you use a gasoline of a lower octane value than
specified, there is a danger that the engine temperature
may rise and an engine problem such as piston seizing
may consequently occur.

HOW TO MIX FUEL
IMPORTANT
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
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
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. Note that, if the agitation is insufficient, there is
an increased danger of early piston seizing due to an
abnormally lean mixture.

5. Indicate the contents on outside of container for easy
identification to avoid mixing with raw gasoline or other
containers.

FUELING THE UNIT
1. Untwist and remove the fuel cap.
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

Do not smoke or place hot objects near fuel.
FOR YOUR ENGINE LIFE, AVOID;
1. FUEL WITH NO OIL (RAW GASOLINE) - It will cause severe
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 sticking.
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.
