Making your generating set run under too high loads will decrease its lifespan. This counts for too low loads as well. If the generating set runs loaded with less than 20% of its maximum load, some problems may occur:

1. Leakage in the in- and/or outlet system
2. Carbon deposits in the combustion chamber and/or in the exhaust manifold
3. Less viscosity of the lubricant
4. Wear that could damage the engine
5. Emission of white smoke
