1 Loosen the vent plug on the side of the fuel injection pump.
2 Operate the priming lever until fuel, free from air, comes from the vent point. Tighten the vent plug.
3 Turn the start key to the "ON" position.
4 Operate the starter motor for intervals of 15 seconds until the engine starts. It is important to allow the electrical components to
cool for 30 seconds between each 15 second interval of operation.
If the engine runs correctly for a short time and then stops or runs roughly, check for air in the fuel system.

Cautions: Damage can occur to the electrical components e.g. the electrical
stop solenoid and the starter motor if they are energized for too long. This
can occur when starting the engine and especially when air is to be
eliminated from the system.
The correct procedure to eliminate air from the fuel system is to only use the
starter motor to start the engine after air has been eliminated from the
low-pressure side of the fuel system.
Note: If air enters the fuel system, it must be eliminated before the engine
can be started.
