ENGINE OIL

Engine Oil Specifi cation
NOTICE
Engine oil is a major factor affecting engine
performance and service life. Never use non-
detergent or 2-stroke engine oils.
It is very important to maintain proper level of engine oil
to keep engine in good running condition. Check engine
oil level prior to each use. Refi ll engine oil if oil level is
too low.
Use engine oils specifi ed below:
Use 4-stroke oil, or equivalent high-detergent,
premium-quality motor oil certifi ed to meet or exceed
U.S. automobile manufacturer's requirements for API
Performance Class SL, SJ or better. Synthetic oil is an
acceptable substitute for conventional oil.
SAE 10W-30 is recommended for general temperature
use. See Figure 7-2 for information on other viscosities
that may be used. Other viscosities shown in the chart
may be used when the average temperature in your
area is within the indicated range.
Conventional 10W-30
5W-30

MAINTENANCE

Low Oil Protection

The generator engine is protected from low lubrication
failure by an oil shutdown switch. This switch prevents
the ignition system from operating until suffi cient oil is
added to the crankcase.
When the engine shuts down due to low oil level:
The engine control switch will remain in the RUN
position.
The ignition system will be inoperable.
The engine will not start until the required amount of
engine oil is added to the engine.

Checking Engine Oil

NOTICE
Always maintain proper engine oil level. Failure to
maintain proper engine oil level could result in severe
damage to the engine and/or shorten the life of the
engine.
Always use the specifi ed engine oil. Failure to use the
specifi ed engine oil can cause accelerated wear
and/or shorten the life of the engine.
Check engine oil level before every use.
1. Always operate or maintain the generator on a fl at
surface.
2. Stop engine if running.
3. Let engine sit and cool for several minutes (allow
crankcase pressure to equalize).
4. With a damp rag, clean around the oil fi ll plug/
dipstick.
5. Remove oil fi ll plug/dipstick (see Figure 7-3).
