AIR FILTER MAINTENANCE
ENGINE OIL RECOMMENDATIONS
Use 4-stroke oil, or equivalent high detergent, premium
quality motor oil certified to meet or exceed U.S. automo-
bile manufacturer's requirements for API Performance
Class SL, SJ, or better.
SAE 10W-30 is recommended for general temperature
use. Refer to Figure 7-1 for information on other viscosi-
ties 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.
NOTE:
Dispose of used motor oil according to guidelines
established by your local or state government.
Low Oil Protection
The generator engine is protected from low lubrication fail-
ure by an oil shutdown switch. This switch prevents the
operation of the ignition system until sufficient oil is added
to the crankcase for proper engine lubrication.
When engine shuts down due to low oil level:
1. The engine control switch will remain in the RUN posi-
tion.
2. The engine will not start until the required amount of
engine oil is added.
7.2 AIR FILTER MAINTENANCE
Clean air filter every 50 hours of generator operation. If
operating generator in extremely dusty areas, clean air fil-
ter more frequently.
1. Stop engine if it is running.
2. Remove air cleaner cover.
For Model Numbers Ending in “L”:
• Unlock the latches at the top and bottom of the air cleaner
cover.
For Non-L Models:
• Turn thumbscrew counterclock wise to loosen and
remove.
• Pull bottom of air cleaner cover out and lift up to release
plastic tabs.
NOTICE
Engine oil is a major factor affecting engine performance
and service life. NEVER use non-detergent or 2-stroke
engine oils.
• Use engine oils specified below.
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. Refill engine
oil if oil level is too low.
FIGURE 7-1: Recommended Oil Viscosity
ALWAYS stop engine before removing oil fill dip-
stick.
Crankcase pressure can cause hot engine oil to
spray out of engine fill hole. Hot engine oil can
cause severe burns.

WARNING
NOTICE
A dirty air filter will restrict air flow to carburetor, which may
cause poor engine performance or damage.
NEVER run the generator without the air cleaner assembly
properly attached.
Gasoline and flammable solvents can cause fire or
explosion. NEVER use gasoline or flammable sol-
vent to clean air filter element.
• Use only household soap and water to clean air filter
element.
To clean air filter, you will need:
Household soap and water
Clean, dry cloth
Clean engine oil
