Additional Maintenance Recommendations

1. Change coolant and replace batteries every two years.

2.  Replace belts and hoses every fiveyears

3.  Load bank testing when a unit cannot beloaded to at least 50% of rated capacity for at least two hours annually. Loading the unit will burn off harmful deposits in the combustion chamber, injector nozzles and exhaustsystem
