Cleaning And Inspecting Supply Module Filter - MacDon M2170 Operator's Manual

WARNING
Wear appropriate eye and face protection when using compressed air. Flying debris and dirt can cause personal injury.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator's seat for any reason.
IMPORTANT:
Any spilled diesel exhaust fluid (DEF) must be contained and absorbed by a non-combustible absorbent material such as
sand. The contaminated absorbent should then be placed into a leak-proof container and disposed of. DEF is corrosive. If
DEF is spilled on the DEF tank or on any other surface of the vehicle, rinse the contaminated surface thoroughly with water.
IMPORTANT:
Do NOT disconnect the windrower batteries until the diesel exhaust fluid (DEF) dosing system has completed its purge
cycle. Before removing or disconnecting any components of the DEF system, wait at least five minutes after the
windrower's ignition switch is turned to the OFF position for the aftertreatment DEF dosing system to purge the DEF from
the system. The purge cycle is an automatic process and does not require the Operator's intervention. The aftertreatment
DEF supply module emits an audible pumping noise during the purging process.
NOTE:
DO NOT power wash or steam clean the filter. Use compressed air to remove any loose debris.
1. Shut down the engine, and remove the key from the ignition.
2. Wait 3 minutes for the DEF system to complete the purge cycle.
3. Place a catch basin under the DEF filter cap to collect the remaining DEF in the filter housing.
4. Unscrew filter cap (A).
5. Remove aftertreatment DEF filter equalizing element (B).
6. Remove old aftertreatment DEF supply module filter
element (D).
NOTE:
Disposable service tool (C) is included with the filter to aid
in filter removal. Use the appropriate end of the tool to
remove the filter. When inserting the tool, a click sound can
be heard which indicates proper engagement with the filter.
7. Discard and replace the filter and equalizing element if
they're removed from the aftertreatment supply module.

Cleaning and Inspecting Supply Module Filter

Once the diesel exhaust fluid (DEF) supply module filter has been removed, it should be cleaned and examined. The
module filter may need to be replaced.
NOTE:
If there is the possibility that contaminated DEF has gone through the DEF supply system, check the DEF filter prior to
discarding the filter.
