Air Filter Indicator
The air filter indicator, used with the dry element filter, is mounted on the unit frame and connected to the engine air
intake. Its function is to indicate when the air cleaner dry element needs to be replaced. In operation: When a
plugged air cleaner decreases intake manifold pressure to 500 mm (20”) WG, the indicator moves to the red line.
The air cleaner element should be replaced and the indicator reset by pressing the reset button.

Air Cleaner, Oil Bath Service
The oil cup should be inspected during pretrip, before each trip. Never allow more than 1/2 inch (12.7 mm) of dirt
deposit in the cup. More than 1/2 inch accumulation could result in oil and dirt carrying over into the engine, caus-
ing accelerated engine wear. Heavily contaminated oil will not allow the air cleaner to function properly.
CAUTION
!
Always cover the engine inlet tube while the air cleaner is being serviced.
1. Stop the engine and remove the oil cup from the air cleaner. Dispose of the oil in an environmentally safe
manner.
2. Remove the inner oil cup from the oil cup and clean both cups.
3. Reassemble and fill both oil cups to the indicated level with oil specified in Section 2.10 .
CAUTION
!
Do not underfill or overfill the oil bath cups. Overfilling cups causes loss of capacity; underfill-
ing cups causes lack of filtering efficiency.
