• Continuous running with very low load. Increase load and have the engine run for a few
hours.
Loss of power.
•
Wrong measurement. Check if the load is measured correctly. Does the Amp meter show the
correct value? When calculating the load by multiplying voltage and amps this should be done
by using the exact values, taking into account the power factor of the consumers. When any
doubt measure the power directly with an appropriate instrument.
•
Overfull oil sump. Bring the oil to the correct level.
•
Choked fuel filter. Replace the fuel filter.
•
Choked air filter Check air inlet openings; clean air filter.
•
Exhaust blocked. Check the exhaust system.
