Ensure that all adjustments and repairs that are carried out to the Diesel Exhaust Fluid (DEF) system are performed by authorized personnel that have the correct training.Before beginning ANY work on the DEF system, refer to Operation and Maintenance Manual, "General Hazard" for safety information.
Care must be taken to ensure that Diesel Exhaust Fluid (DEF) for the system are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Ensure that the purge process for the DEF system is completed before turning the battery disconnect switch to the OFF position. Refer to the Operation and Maintenance Manual, "Battery Disconnect Switch" for further information.
Refer to the Original Equipment Manufacture (OEM) for the location and removal of the diesel exhaust fluid tank.
Drain the coolant from the cooling system to a level below the solenoid valve, into a suitable container for storage or for disposal. Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the correct draining procedure.
