CARE AND MAINTENANCE
CHANGING THE ENGINE OIL
See Figure 21.
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.
l Turn the generator off and allow the engine to cool for
30 minutes.
l Place the generator on a level surface in a well-
ventilated area.
l Clean the area around the oil dipstick.
l Slowly unscrew and remove the oil dipstick.
l Place an oil pan (or suitable container) under the oil
drain bolt.
l Remove the oil drain bolt and allow the oil to drain.
l After the oil has drained completely, replace the oil drain
bolt.
l Refill the oil as described in the Operations section.
l Replace the oil dipstick and hand-tighten.
l Clean up any spilled oil.
CLEANING/REPLACING THE SPARK PLUG

l Measure the spark plug electrode gap with a wire-type
feeler gauge. If necessary, correct the gap by carefully
bending the side electrode.
