6.4Starting Procedure
The injection system has automatic cold start compensation.
First time in operation:
1.Turn on the ignition system.
2.Turn on the injection system.
3.Open the throttle valves fully.
4.Turn the injection system on a second time for a total of 10 seconds of purge to allow the system to fully
evacuate air from the system.
5.Close the throttle fully.
6.Engage starter to start the engine. Should the engine not start, you may need to open the throttle valves
slowly during start up.
Note: The starting sequence should be interrupted after a maximum of 20 seconds, if the engine doesn?t start.
After a short break repeat starting sequence.
7.As soon as the engine runs on it?s own, turn off the starter and keep engine running with 2-3 short burst
of acceleration.
8.Warm up the engine at 2000-3000 RPM under a light load
9.If the engine is warm, adjust throttle to idle
10.During and after the first operation you have to do the following test on the injection system:
Check the fuel lines and connections for leaks.
Check fuel lines for cracks and signs of rubbing.
Check electrical lines for secure connections and signs of stress.
Check throttle cable for smooth operation and security.
Check idle speed and adjust if necessary.
Exchange any damaged parts, and install new parts in accordance to proper installation procedures to
avoid damage.
6.5Starting the engine
Cold engine
1.Turn on the ignition system.
2.Turn on the injection system.
3.Start the engine with throttle fully closed. Should the engine not start under those conditions, open the
throttle slowly while starting the engine.
Note: If engine doesn?t start, stop the starting sequence after a maximum of 20 seconds. After a short
break, repeat starting sequence.
4.If engine fails to start after repeated attempts with above procedure. Advance throttle to full open
position. This will cause the injectors to spray at 100% for 1 second. Return throttle to closed position
