(5) Fuel priming pump button
The 30ESX,40ESX is provided with an fuel priming
Pump button. The button is used to vent the air
contained in fuel piping before the engine that has been
stopped because of fuel shortage, etc. is started.
In such a case, set the starter switch to "Run", press
down the fuel priming pump button for about 1 minute,
and then start the engine.
If the engine rotation is found unstable after it is started,
press down the button again for about 10 seconds while
the engine is running.
With the 30ESX air vent can also be performed with the priming pump located at
the top of the filter. If air cannot be vented completely when this button, press the
priming pump several times.
I f the engine still rotates unstably or still fails for starting, clean up the Fuel Filter
Element located into the Fuel Pump, or replace it to new one.
