3.3.6 REPLACING THE SPARK PLUG

See Engine Specifications for recommended spark plug. Replace
the plug once each year. This will help the engine start easier and
run better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
(Figure 12).

3.3.7 BATTERY REPLACEMENT

The battery shipped with the generator has been fully charged.
A battery may lose some of its charge when not in use for
prolonged periods of time. If the battery is unable to crank the
engine, plug in the 12V charger included in the accessory box
(see the Charging a Battery section). RUNNING THE GENERATOR
DOES NOT CHARGE THE BATTERY.
The NEGATIVE battery terminal should:
1. Always be DISCONNECTED FIRST.
2. Always be CONNECTED LAST.

NOTE:

3.4 SERVICE AIR CLEANER

The engine will not run properly and may be damaged if using
a dirty air cleaner. Clean or replace the air cleaner paper filter
once a year. Clean or replace more often if operating under dusty
conditions (Figure 14).
To clean or replace paper air filter:
• Remove air cleaner cover and remove paper filter.
• Clean paper filter by tapping it gently on a solid surface. If the
filter is too dirty, replace it with a new one. Dispose of the old
filter properly.
• Clean air cleaner cover, then insert new paper filter into the base
of the air cleaner. Re-install air cleaner cover.

To order a new air filter, please contact the nearest authorized
service center at 1-800-333-1322.

3.5 LONG TERM STORAGE

It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during storage. Acidic
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be emptied
before storage of 30 days or longer, as follows:
• Remove all gasoline from the fuel tank.
 Drain fuel into approved container outdoors,

away from open flame. Be sure engine is cool.
Do not smoke.
