ROUTINE AND PERIODIC ENGINE MAINTENANCE
WARNING
To prevent the engine from accidentally starting, dis- connect the negative battery cable before servicing the engine.
See Table D.1 for a summary of maintenance inter- vals for the items listed below. More frequent service may be required, depending on your specific applica- tion and operating conditions. See the Kubota Engine Operator's Manual for further information
OIL
Check the oil level before starting engine or daily. BE SURE TO MAINTAIN THE OIL LEVEL. Change the oil for the first time after 50 hours of oper- ation. Then, under normal operating conditions, change the oil as specified in the maintenance sched- ule.
CHANGING THE OIL
Change the oil, while the engine is still warm, as fol- lows:
1.Drain the oil from the drain plug located on the engine bottom, as shown in Figure D.1.
2.Replace the plug and tighten it securely.
3.Remove the oil fill cap and add oil until the level reaches the full mark on the dipstick. The quantity of oil required for an oil and oil filter change is 5.4 quarts (5.1 L). Use oil that is rated for diesel engine service (API classification CD/CE). Use SAE viscosity grades per the following table:

4.Reinstall the oil fill cap and the dipstick and start the engine. Run for several minutes and stop engine - Wait 5 minutes to allow the oil to come down to the oil pan and check oil level again.

OIL FILTER
Change the oil filter the first time after 50 hours of operation. Then, under normal operating conditions, change the oil filter at every oil change.
Change the oil filter as follows:
1.Drain the oil from the engine and allow the oil filter to drain.
2.Remove the old filter (spin it off) and discard it. Wipe off the filter mounting surface and adapter.
3.Apply a thin coat of new oil to the rubber gasket on the new oil filter.
4.Spin the new filter on to the mounting adapter until the gasket just touches the mounting surface, then turn it down another 1/2 to 3/4 turn. Do not over- tighten the new filter.
5.Refill the engine with the proper amount and type of oil as described in the CHANGING THE OIL section. Start the engine and check for leaks around the filter element. Correct any leaks (usu- ally by retightening the filter, but only enough to stop leaks) before placing the RANGER 300 back in service.
6.If there are no leaks, stop the engine and recheck the oil level. If necessary, add oil to bring the level up to the FULL mark, but do not overfill.
