WARNING
DO NOT run the pump dry.
Running the pump dry can destroy the pump
seals and will void the warranty.
If the pump was running while dry, stop the
engine and allow it to cool thoroughly before
filling the chamber with water.
Starting the Engine
1. Make certain the water pump is on a
flat, level surface.
2. Flip engine switch to “ON” position
3. Rotate the fuel valve to the “ON”
position (to the left). See image below
4. Move the choke lever (Item A) to the
“Choke” position (to the left).
5. Pull the starter cord slowly until
resistance is felt and then pull rapidly.
6. As engine warms up, move the choke
lever to “Run” (to the right).
7. Move the throttle lever (Item B) to the
“Fast” position.
NOTE
If the engine starts but does not run make
certain that the water pump is on a flat, level
surface. The engine is equipped with a low oil
sensor that will prevent the engine from running
when the oil level falls below a critical threshold.
Pump performance can be adjusted using
the throttle. To decrease pump output, slide
the throttle to the right. To increase it, slide
the throttle to the left.
Stopping the Engine
1. Turn the ignition switch to the “Off”
position.
2. Rotate the fuel valve to the “Off”
position.
3. Allow the engine to cool thoroughly.
4. Remove the cap from the cooling pump
chamber and allow it drain completely.
