Maintenance and Specifications OCR precautions and safe exhaust position WARNING: Failure to comply with the following instructions for operator commanded regeneration (OCR) may result in fire, serious injury, death and/or property damage. Before you start OCR, observe/do the following: • Place the vehicle in P (Park) with the parking brake set on stable, level ground. • The vehicle must not be parked in a structure. • The vehicle must be 10 - 15 feet (3 - 5 meters) away from any obstructions, • and must be away from materials that can easily combust or melt such as: paper, leaves, petroleum products, fuels, plastics and other dry organic material, such as grass. • Make sure there is a minimum of 1/8 tank of fuel. • Make sure all fluids are at proper levels. Make sure that the louvers (holes) located at the tip of the exhaust are also clear of any obstructions as they are used to introduce fresh air into the tailpipe to cool the exhaust gas as it leaves. See Exhaust under the Cleaning chapter for more information. How to start operator commanded regeneration (OCR) WARNING: Stay clear of exhaust tip during regeneration. You or others can be burned. Note: OCR will not be allowed until DPF load percentage has reached at least 80%. The DPF load percentage will fluctuate up and down when driving your vehicle due to active and passive regenerations. Note: OCR will not be allowed to operate if the service engine soon is illuminated light Note: During the use of OCR, you may observe a light amount of white smoke. This is normal. Note: During stationary PTO operation, OCR will change the engine speed to 2,000 or 2,400 rpm (depending on vehicle application), therefore it is recommended you exit PTO mode before starting OCR. During mobile PTO use, OCR is not necessary; regeneration will function normally. 59 2012 Diesel (67l) Supplement, 3rd Printing USA (fus)
