certain period of time is required before the engine oil completely flows down from the oil filler to the crankcase.

4.Check the oil level, accounting for the higher oil level due to the oil filter oil capacity.

A specially designed dry filter is standard equipment on these tractors and supplies clean combustion air to the engine. Figure 4-16 Change the filter whenever the Air Cleaner Restriction Warning Light comes on. Figure 3-1

engine protection and air cleaner service life, install a new inner safety element every third primary element change or after every 1000 hours of operation, whichever comes first.

NOTE: The safety filter does not require servicing unless it becomes contaminated with dirt or moisture.

Recommended service procedure

1.Release clamps and remove element. Clean the canister with a damp cloth.

2.Before installing a new element, inspect it by placing a bright light inside and rotate the element slowly, looking for any holes or tears in the paper. Also check gaskets for cuts or tears. Do not attempt to use a damaged element which will allow abrasive particles to enter the engine.

3.Install the new element and reinstall the dust cup. Make sure it seals all the way around the air cleaner body, then tighten the clamps.

4.Check all fittings and clamps periodically for tightness and inspect hoses for holes or cracks.

5.Periodically check the intake hose for signs of ingested dust. Locate and repair the source of ingested dirt.

6.Never operate a machine without an air filter installed.

Overservicing

Overservicing occurs when an air filter element is removed for cleaning or replacement before it is necessary. Each time the filter is removed a small amount of dirt and dust could fall in the intake system. This accumulated dirt can cause a dusted engine. It only takes a few grams of ingested dirt over the normal service life of an engine to cause a dusted engine.

Do not clean element, replace with a new element only. Cleaning used air filter elements, through improper cleaning procedures, can get dust on the inside of the filter causing dirt ingestion and engine failure.
