Change Engine Oil

1.Refer to the Engine Manual for proper oil specifications, procedures and proper service intervals.

2.For the simplest/cleanest oil change, simply turn the mower on its side to drain the oil, as shown. Drain the oil through the dipstick tube (A, Figure 13) into a container. Allow sufficient time for all the oil to drain.

Important: Drain the fuel tank before tipping the machine. DO NOT tip the machine with the carburetor or spark plug down. Oil from the crankcase will saturate the air filter and cause the engine to be hard to start or not start at all. If contamination does occur, the air filter will have to be replaced.
