Contaminated fuel can also trigger lockout. Contamination sources include water infiltration from missing or damaged tank covers, condensation within the tank, sludge from microbial growth at the water-fuel interface, and rust corrosion in metal tanks. Contact an OFTEC registered engineer for tank cleaning and oil line flushing if contamination is suspected.
