FUEL
WARNING
• Gasoline is very flammable. Avoid smo king 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 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.
•
• R E C O M M E N D E D
GASOLINE 50 : OIL 1 (when using Husqvarna
genuine oil)
• Exhaust emission are controlled by the funda-
mental engine parameters and components (eq.,
carburation, ignition timing and port timing) with-
out addition of any major hardware or the introduc-
tion 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 pre-
scribed, there is a danger that the engine temperature
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.
GB-8
M I X I N G R A T I O
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 nec-
essary 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 container 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 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 sufficiently 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. 6. In the case of scrapping the used mixed oil
container, scrap it only at an authorized repository site.
