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.
HOW TO ADD FUEL
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 explosion and cause
fatal or serious injuries to you or a bystander.
DANGER! Static electricity can ignite gas fumes. Touch a
grounded object to discharge the static electricity before
adding fuel to the engine.
1. Refuel outdoors or in a well-ventilated area and immediately wipe
up spills. 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 area of dirt and debris. Do not allow dirt or
water to enter the fuel tank.
5. Remove the fuel cap slowly to allow the pressure to equalize.
6. Check the fuel level.
7. Add fuel until it reaches the fuel level mark. If no mark is visible, fill
the tank to approximately 1.5 in. (38 mm) below the top of the fuel
tank to allow for fuel expansion. Take care to not overfill the tank. It
