FUEL

WARNING
• Gasoline is very fl ammable. Avoid smo king or
bringing any fl ame 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 Husqvarna engines are lubricated by oil specially
formulated for air-cooled 2-cycle gasoline engine use.
If Husqvarna 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:
A. GASOLINE 40 : OIL 1 (when using Husqvarna
genuine oil)
B. GASOLINE 25 : OIL 1 (when using other oil)
• These engines are certifi ed to operate on unleaded
gasoline.
• Make sure to use gasoline with a minimum octane
number of 89RON (USA/Canada: 87AL).
• Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
• If you use a gasoline of a lower octane value than pre-
scribed, there is a danger that the engine temperature
may rise and an engine problem such as piston seizing
may consequently occur.
• Clean, fresh and 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.

To mix the fuel

WARNING
• Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be
mixed.
GB-10
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 diffi cult to agitate
depending on oil ingredients, suffi cient agitation is
necessary for the engine to last long. Be careful that,
if the agitation is insuffi cient, there is an increased
danger of early piston seizing due to abnormally lean
mixture.
5. Put a clear indication on the outside of the container
to avoid mixing up with gasoline or other containers.
6. Indicate the contents on outside of container for easy
identifi cation.

To fuel 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 capacity.
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 3 meters (10 feet ) away from the fueling
point before starting the engine.
3. Stop the engine before refueling the unit. At that time,
be sure to suffi ciently agitate the mixed gasoline 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 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 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 carburetor of the
composite fuel.
6. In the case of scrapping the used mixed oil container,
scrap it only at an authorized repository site.
