Diesel Exhaust Fluid (DEF)
System
The DEF system is an efcient, effective means of
ltering dirt and other contaminates for optimum
machine performance and reducing air pollution from
exhaust emissions. A sensor on the DEF tank header
monitors the level, temperature and quality of DEF in
the tank. The header is mounted on top of the DEF
tank and provides ltered DEF supply from the tank to
the aftertreatment DEF dosing unit. Both the DEF tank
header and dosing unit have serviceable lters that
require cleaning or replacement. Fill the DEF tank with
DEF uid at any gas station and be sure to keep the tank
full. (Figure 5-7)
The DEF system will automatically purge the uid
from the system after shutting down the machine and
requires no intervention from the operator.
NOTE: Check the ttings around the DEF tank
header for leaks or any signs of damage
regularly. DEF leaks will leave a white
deposit around the ttings.
DO NOT pressurewash or steamclean
this unit to avoid damage the components. Use
compressed air to remove any loose debris.
DEF contains urea, therefore, wear
safety glasses when performing these procedures.
DO NOT get the substance in your eyes. In case of
contact, immediately ush eyes for a minimum of 15
minutes.
Before servicing any component in the DEF system,
allow the DEF system to purge. You will hear the
pumping noise as the system completes the purge cycle
automatically after shutting down the engine.
1. Shift transmission into neutral.
2. Apply the parking brake.
3. Shut off the engine. Wait at least ve minutes after
shutting down the engine for the aftertreatment DEF
dosing unit to complete its automatic purge cycle.
DO NOT disconnect battery until the
purge cycle has completed to prevent damage to the
unit.
4. Place battery master switch in the OFF position.

It’s important to service the DEF
system in a clean, dust-free environment to prevent
contamination in the DEF tank that can damage the
aftertreatment DEF dosing unit.
