Note:

Never use a mixing ratio less than 50:1 regardless of the oil package mixing instruc-
tions.  Ratios less the 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of
lubrication to the internal moving parts of the engine and can cause damage.

Mixing Instructions

IMPORTANT: Never mix gasoline and oil directly in the Water Pump 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 Water Pump.

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 fill-
ing the fuel tank on the Water Pump.

6.

When refilling the Water Pump fuel tank, clean around the fuel tank cap to prevent 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 1/4-1/2 inch (6 mm-13 mm) from the top of the tank.  Avoid filling to the
top of the tank filler neck.
