Re-fuel at the earliest convenience.

If only the fuel low error is shown, the generator can still function.

If the fuel empty error is shown, or if the fuel level reaches 10% or less, the generator may shut-down in order to prevent damage to the generator.

Call forwarder/supervisor and consider the following steps:

1. Check if there is a suitable external power source nearby (on the truck).
2. Check if there is a NATO cable available.

Some AKP's contain a NATO cable, which can be found underneath the generator or CCU.

IMPORTANT: Only use the NATO cable! Only use 12V! Always consult the OM (Operation Manual) in when in doubt!

Yes, there is a suitable NATO 12V source
No, there is no suitable NATO 12V source
I don't have a NATO 12V cable available
Back to start

Inform forwarder/supervisor and consider the following:

WARNING: Only use the NATO cable with 12V!

Connect the NATO cable to the source (red is positive, black is negative) and generator, start the generator and let it run for at least 15 minutes.

The NATO cable can be disconnected if the generator is running. Does the generator now start?
