Removing Supply Module Filter

The windrower's diesel exhaust fluid (DEF) supply module filter may need to be removed for replacement or inspection.
WARNING
Batteries emit explosive gases. To reduce the possibility of personal injury, always ventilate the compartment before
servicing the batteries. To reduce the possibility of electrical arcing, remove the negative (–) battery cable first and
attach the negative (–) battery cable last.
WARNING
Diesel exhaust fluid (DEF) contains urea, which can irritate the skin, eyes, digestive, and respiratory systems. Do NOT
get the substance in your eyes. In case of contact, immediately flush your eyes with water for a minimum of 15
minutes. Do NOT ingest DEF. If DEF is ingested, contact a doctor immediately.
WARNING
The DEF line connecting the aftertreatment DEF dosing unit to the aftertreatment DEF dosing valve is under low
pressure and should NOT be disconnected while the engine is running or before the system has completed the purge
process after engine shutdown. Disconnecting the DEF line while under low pressure could cause DEF to spray.
