Recommended fuel type
Use clean, unleaded gasoline with an octane rating of 85 or higher. Use of unleaded gasoline results in fewer
combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary or
recommended.
IMPORTANT: Never use gasohol or alcohol blended fuels in this engine.
Mixing gasoline and oil
IMPORTANT: The engine used on this Earth Auger is of a two-stroke design. The internal moving
parts of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall contact
surfaces, require oil mixed with the gasoline for lubrication. Failure to add oil to the gasoline or
failure to mix oil with the gasoline at the appropriate ratio will cause major engine damage which will
void your warranty.
Fuel mixture
The fuel: oil ratio is 25 parts gasoline to 1 part oil or 25:1.

Mixing instructions
IMPORTANT: Never mix gasoline and oil directly in the Earth Auger fuel tank.
1. Always mix fuel and oil in a clean container approved for gasoline.
2. Mark the container to identify it as fuel mix for the Earth Auger.
3. Use regular unleaded gasoline and fill the container with half the required amount of gasoline.
4. Pour the correct amount of oil into the container then add the remaining amount of gasoline.
5. Close the container tightly and shake it momentarily to evenly mix the oil and the gasoline before filling
the tank on the Earth Auger.
6. When refilling the Earth Auger fuel tank, clean around the fuel tank cap to stop dirt and debris
from entering the tank during cap removal.
7. Always shake the premix fuel container momentarily before filling the fuel tank.
8. Always use a spout or funnel when fueling to reduce fuel spillage.
9. Fill the tank only to within 10mm from the top of the tank. Avoid filling to the top of the tank filler neck.
