Removing and Installing Fuel Filters

CAUTION:

X9811-UN-23AUG88

High Pressure Fluids

If ANY fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury or gangrene may result. Doctors unfamiliar with this type of injury may call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.

CAUTION: Due to High Pressure Common Rail system design, fuel in filter is likely to be under high pressure. To avoid possible personal harm, open valves (B) and (J) on bottom of filters to relieve pressure prior to removing each filter.

IMPORTANT: Replace fuel filter elements anytime audible alarm sounds and trouble codes indicate plugged fuel filters (low fuel pressure). If no alarm sounds during the 12 month service interval, replace elements at that time, or after 250 hours operation, whichever comes first.

Both Primary and Final filters must be replaced at the same time.

Remove and Install Primary Fuel Filter Element

IMPORTANT: Do NOT pre-fill filter with fuel. This may introduce debris into the fuel system.
