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.

NOTE: May require cleaning sooner in very dusty conditions.

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

7. Feeder House Reverser Gearcase - Raise feeder house and lower safety stop. Gearcases with an oil cooler will require gearcase be run for several minutes. This ensures that the cooler is filled with oil. Oil level must show on knurled part of dipstick (F).

8. Contour-Master Feeder House - Check cleanout areas (G) for packed material which could prevent header from tilting completely to either side. Clean out if required.
