OPERATION
8. If the engine has started, and the choke lever was
moved to the
CLOSED
position to start the engine,
gradually move the choke lever to the
OPEN

(Figure 9) as the engine warms up. If the engine has
not started repeat steps 1 through 6.
9. Before the water trailer is placed into operation, run
the engine for several minutes.
10. Check for fuel leaks and noises that would be
associated with a loose component. Check for leaks
between pump and engine. If water is leaking between
the pump and engine housing, the seal inside the
pump may be worn or damaged. Continued operation
of the pump is not recommended. Further usage of the
pump under these conditions may cause severe water
damage to the engine.
11. To begin pumping, place the throttle lever (Figure 12)
in the
RUN
