Quick guide to answer questions, incidents and frequent problems

  • The starter does not rotate

    Check that:

    • The batteries are not flat.
    • The electrical connection is not poor.
    • The starter engine wiring and connections are correct.
    • The starter engine/solenoid are not defective.

    If, after checking all this, the problem persists:
    You may need to replace defective parts or check the electrical connection to the engine. Contact our After-Sales team to solve the issue as soon as possible.

  • Starter rotates slowly

    Check that:

    • The batteries are not flat.
    • The electrical connection is not poor.

    If, after checking all this, the problem persists:

    You may need to check the electrical connection to the engine.

    Contact our After-Sales team to solve the issue as soon as possible.

  • The starter works correctly, but the engine does not start

    Check that:

    • The starter engine/solenoid are not defective.
    • The tank is not empty or there is not enough fuel.
    • The fuel taps are closed and the tank is not poorly attached.
    • The fuel filter is not deficient (it is not too fine or the pre-filter is clogged due to the presence of impurities).
    • There is no air in the fuel system.
    • No impurities or water in the fuel.

    If, after checking all this, the problem persists:

    Make a final check that the fuel circuit is in good condition and, if this has not been sufficient to solve the problem, contact our After-Sales team to solve the issue as soon as possible.

  • The engine starts, but then stops

    Check that:

    • The tank is not empty or there is not enough fuel.
    • The fuel filter is not deficient (it is not too fine or the pre-filter is clogged due to the presence of impurities).
    • There is no air in the fuel system.
    • No impurities or water in the fuel.
    • No intake air insufficiency is occurring:
      • Because the air filter is clogged.
      • Because there are leaks in the air intake circuit.
      • Because the compressor is dirty.
      • Because the turbocharger is faulty.
      • Because the ventilation is poor in the engine compartment.
      • Because the arrangement of the set in the room is incorrect.
    • There are no other alarms indicated on the control board.

    If, after checking all this, the problem persists:

    Make a final check that the fuel circuit and air intake parameters are in good condition and, if this has not been sufficient to solve the problem, contact our After-Sales team to solve the issue as soon as possible.

  • Engine runs erratically

    Check that:

    • There is no air in the fuel system.
    • No impurities or water in the fuel.
    • The rev regulator/actuator is not properly adjusted.

    If, after checking all this, the problem persists:

    If the problem persists after checking the points detailed above, please contact our After-Sales team to solve the issue as soon as possible.

  • The generator set consumes too much fuel

    Check that:

      • Because the air filter is clogged.
      • Because there are leaks in the air intake circuit.
      • Because the compressor is dirty.
      • Because the turbocharger is faulty.
      • Because the ventilation is poor in the engine compartment.
      • Because the arrangement of the set in the room is incorrect.
    • Coolant temperature is not too low.
    • There is no excessive exhaust back pressure.

    If, after checking all this, the problem persists:

  • Exhaust gas is black

    Check that:

    • The injection pumps are not defective.
    • No intake air insufficiency is occurring:
      • Because the air filter is clogged.
      • Because there are leaks in the air intake circuit.
      • Because the compressor is dirty.
      • Because the turbocharger is faulty.
      • Because the ventilation is poor in the engine compartment.
      • Because the arrangement of the set in the room is incorrect.
