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
10ft (3m) away from the fuel-
ing point before starting the
engine.
• The 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
GASOLINE 50:OIL 1
• Exhaust emission are
controlled by the
fundamental engine
parameters and components (i.e., carburation,
ignition timing and port timing) 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 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.
• 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

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
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 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 around the unit.
WARNING
1. Select bare ground for fueling.
2. Move at least 10 feet (3 meters) away from the
fueling point before starting the engine.
3. Stop the engine and let it cool for a few
minutes before refueling the unit. At that time,
be sure to sufficiently agitate the mixed
gasoline in the container.
4. 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 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.
5. When 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. When scrapping the used mixed oil container, scrap
it only at an authorized repository site.
NOTE
For details of quality assurance, read the
description in the Warranty section carefully.
Moreover, normal wear and change in product
with no functional influence are not covered by
