FUEL; MIXING GASOLINE AND OIL
WARNING!
The engine used on this water pump is of a 2-cycle design. The internal moving parts
of the engine, i.e., crankshaft bearings, piston pin bearings and piston to cylinder wall contact sur
faces, 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. For your fuel premix, only use Maruyama 50:1 2-Cycle Oil or a quality oil designed
for 2-cycle air-cooled engines.
FUEL MIXTURE:
When using genuine Maruyama 50:1 2-Cycle Oil, the fuel: oil ratio is 50 parts
gasoline to 1 part oil or 50:1. If Maruyama 2-cycle engine oil is not available, use a good quality 2-
cycle, are-cooled engine oil mixed at a ratio of 25:1.
NOTE: if Maruyama oil is not used, never use a mixing ratio less than 50:1 regardless of the
oil package mixing instructions. 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:
Always mix fuel and oil in a clean container approved for gasoline.
Mark the container to identify it as fuel mix for the water pump . Use regular unleaded gasoline and
fill
the container with half the required amount of gasoline. Pour the correct amount of oil into the
container then add the remaining amount of gasoline. Close the container tightly and shake it
momentarily to evenly mix the oil and the gasoline before filling the fuel tank on the water pump.

When refilling the fuel tank, clean around the fuel tank cap before removing it to prevent dirt and
debris from entering the tank during cap removal. Always shake the premix fuel container momen
tarily before filling the fuel tank.
Always use a spout or funnel when fueling to reduce fuel spillage. Only fill the tank to within 1/4--
1/2 inch from the top of the tank. Avoid filling to the top of the tank filler neck.
