CHANGE THE OIL FILTER: Change the oil filter the first time between 25 and 50 hours of operation. Then, under normal operating conditions, change the oil filter after every 250 hours of operation. If the engine is operated under heavy load or in high ambient temper- atures, change the oil filter more frequently. See Table D.1 for recommended maintenance intervals. See Table D.2 for replacement oil filters.

Change the oil filter as follows:

1.Remove the oil drain plug. Drain the oil from the engine and allow the oil filter to drain. See Figure D.1.

2.Remove the old filter (spin it off) and discard it (2). Wipe off the filter mounting surface and adapter. See Figure D.1.

3.Fill the new filter with fresh engine oil. Apply a thin coat of new oil to the rubber gasket on the new oil filter.

4.Spin the new filter onto the mounting adapter finger tight until the gasket is evenly seated. Then turn it down another 1/2 turn. Do not over tighten the new filter.

5.Refill the engine with the proper amount and type of oil as described in the Change the Oil section, above. 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 Commander 400 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 “MAX” mark, but do not overfill. See Figure D.1.

FUEL: At the end of each day's use, refill the fuel tank to minimize moisture condensation and dirt contamina- tion in the fuel line. Do not overfill; leave room for the fuel to expand.

Refer to your engine operation manual for recom- mended grade of fuel.
