· After-treatment diesel particulate filters should be inspected prior to cleaning using appropriate OE technical procedures. · DPF cleaning machines are not designed to clean DPF filters that are plugged as a result of excessive fluids in the exhaust system, such as coolant, fuel, or oil. · SPX is not liable for a pre-existing condition in the DPF that would render the filter unstable, if using the cleaning machine identifies such a condition exists. Particulate filters that do not pass these criteria should be replaced and not cleaned.
