Changing the Engine Oil

Change the engine oil after the first two operating hours,
after every 25 operating hours, and at the end of the
snowthrowing season. If possible, run the engine just
before changing the oil because warm oil flows better and
carries more contaminants.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 32).
