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.

DANGER! Fuel is very flammable. Use extreme care when handling or storing
fuel. An ignition source contacting the fumes or fuel may result in a fire or

Fuel can damage paint and plastic.
2. Stop the engine and position equipment on a level surface.
3. Let engine cool at least 2 minutes before removing the fuel cap.
4. Clean the fuel cap (I) area of dirt and debris. Do not allow dirt or water to enter
the fuel tank.
