CHANGING THE ENGINE OIL
See Figure 15.
For optimal performance, change the engine oil according
to the figures specified in the maintenance schedule or
the engine manual (if applicable). When using the generator
under extreme, dirty, dusty conditions or in extremely hot
weather, change the oil more frequently.
NOTE: Change the oil while the engine is warm but not
hot. Warm engine oil drains more quickly and thoroughly
than cool lubricant. Contact with hot lubricant will cause
serious burns.
