V 1.0
FUEL RECOMMENDATIONS
NOTICE! Do not use unapproved gasoline, such as E85. Do not mix
oil in gasoline or modify the engine to run on alternate fuels. This
can damage the engine components. To protect the fuel system
from gum formation, mix a fuel stabilizer into the fuel.
This engine is certified to operate on unleaded gasoline with a
minimum of 87 octane/87 AKI (91 RON). Use gasoline without
ethanol or similar alcohol based additives. Gasoline with up to
10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl
ether) may be used if required.
If the engine is routinely operated at altitudes over 5,000 ft (1,524
meters), it will be necessary to have a qualified technician modify
the engine for increased performance. Fuel should be a minimum
of 85 octane/85 AKI (91 RON) to prevent decreased performance.
The emissions control system for this engine is EM (Engine
Modifications).
1. Use only an approved fuel container for refueling the engine.
2. Store fuel out of direct sunlight in a cool and dry location.
3 Inspect container for fuel leaks. Replace any container
that leaks.
4. You may occasionally hear a light spark knock or pinging
(metallic rapping noise) while the engine is operating under
heavy loads. This is no cause for concern. If spark knock or
pinging occurs at a steady engine speed under normal load,
switch to a premium gasoline or change brands of gasoline. If
spark knock or pinging persists, see an authorized repair centre.
5. Never use stale or contaminated gasoline or an oil/gasoline
mixture designed for two-stroke motors.
