Light load and stand-by generating sets
Engines operating on a load of less than 25-30% of rated output should be run on no load for 10 minutes
weekly and once a year using a variable ‘dummy load’, building up gradually from zero to maximum over a four
hour run, to burn off accumulations of carbon in the engine and exhaust system.
Warning! Failure to follow the instructions above can result in engine damage, and will invalidate the engines
warranty.
