4. FUEL
WARNING
Petrol 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. Use outdoors for
refueling and move at least 3m (10 ft)
away from the fueling point before
starting the engine.
The engines are lubricated by oil specially formulated for
air-cooled 2-stroke petrol engine use. If SGS 2-stroke oil
is not available, use a red semi-synthetic 2-stroke oil.
Do not use BIA or TCW (2-stroke water-cooling type)
mixed oil.
RECOMMENDED MIXING RATIO
PETROL 40 : OIL 1
WWW.SGS-ENGINEERING.COM
CALL FOR ASSISTANCE: 01332 576 850

PAGE 21
PAGE 20
4. FUEL
Exhaust emission are controlled by the fundamental
engine parameters and components (eq. 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
petrol.
• If you use petrol of a lower octane value than
described there is danger that the engine
temperature may rise which may cause an engine
piston to seize.
• Unleaded petrol is recommended to reduce the
contamination of the air for the sake of your health
and the environment.
• Poor quality petrol or oils may damage sealing rings,
fuel lines or fuel tank of the engine.
4. FUEL - HOW TO MIX FUEL
Pay attention to agitation.
1. Measure out the quantities of petrol and oil to be
mixed.
2. Put some of the petrol into a clean, approved fuel
container.
3. Pour in all of the oil and mix thoroughly.
4. Pour in the rest of the petrol and mix again. As some
oils may be more difficult to mix depending on the
oil ingredients, sufficient mixing is necessary to help
improve the engines life. Be careful that if mixing is
insufficient there is increased danger of early piston
seizing due to lack of lubrication.
5. Indicate the contents inside the container by placing
a clear indication on the outside of the container for
easy identification and to avoid mixing up with petrol
or any other containers.

plastic parts and disrupt engine lubrication.
OIL FOR 4-STROKE ENGINES - It can cause spark plug
fouling, exhaust blockages or piston ring sticking.
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.
In the case of storing the product for a long period of time,
clean the fuel tank after completely emptying it. Start the
engine to empty the carburetor of any remaining fuel.
In the case of disposing of used mixing containers, only scrap
it at authorized sites.
As for details of quality assurance, read the description
section Limited Warranty carefully. Normal wear and change
in product with no fuctional influence are not covered by the
warranty. Also, be careful that if the usage in the instruction
manual is not followed (mixed petrol, etc.) as described, it may
not be covered by the warranty.
