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.
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.
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.
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 (F) 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. 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 may be necessary to lower the fuel level
depending on operating conditions.
8. Reinsert the fuel tank cap and tighten.
9. Wipe up any spilled fuel before starting the engine or allow to evaporate. Spilled fuel is
both a fire hazard and an environmental hazard. Dispose of the fuel soaked rags in a proper
hazardous waste container.
ENGINE OIL
High-quality detergent engine oils are acceptable if the American
Petroleum Institute (API) performance rating is
SE, SF, SG or higher. Always check the API service label on
the oil container for the performance rating. Do not use
special additives.
SAE 10W-30 is recommended for general use. Other viscosities
may be used when the average temperature in your area is within
the range indicated in the chart below.
* Below 4 °C (40 °F), the use of SAE 30 will result in hard starting.
**Above 27 °C (80 °F), the use of 10W-30 may cause increased oil consumption. Check oil level.
