2. Primary Fuel/Water Separator Filter - Visually inspect primary fuel/water separator filter (B) and clean if buildup is visible. Close fuel tank shut off valve. Remove filter when a performance decline is noticed or diagnostic trouble code is generated. Open fuel tank shut off valve to fill (see Primary Fuel/Water Separator and Secondary Fuel Filter Replacing in Service Engine section).

3. Radiator, Charge Air Cooler, Oil Cooler and Condenser - Clean radiator by blowing compressed air from inside out. Check areas for chaff buildup and clean if necessary.

4. Mass Flow Sensor - Lower auger and clean mass flow sensor plate.

5. Two Speed Separator Drive - Remove dipstick (C) and check oil level. Add oil as needed to correct level on dipstick.

6. NOTE: May require cleaning sooner in very dusty conditions.

   Fresh Air Filter - Loosen knob (D) and remove filter door. Remove wing nut (E) and slide filter out. Clean or replace filter.
