CHANGING THE FUEL FILTER
Locate the fuel filter, just below the engine intake housing (Figure
11). Make sure the Fuel Shutoff is in the “OFF” (O) position.
1. Remove the pinch clamps securing the fuel filter. Pull the
hoses free.
Wipe up any fuel spills immediately! Do not
smoke or replace the fuel filter near sparks
or open flame!
2. Replace the used filter with a new one (Part Number
0H43470180). Push the fuel hoses onto the barbed filter
fittings until they are seated completely.
3. Replace the clamps, making sure they are seated on the
fittings.

CHANGING THE SPARK PLUG
Replace the spark plug each year, regardless of how many hours
the generator has been run. Use the spark plug identified in the
"SPECIFICATIONS" section for each generator size. The spark plug
gap should be .030” (.76mm). To replace the spark plug:
1. Remove the spark plug cover on the top right side of the
generator, just below the handle (Figure 12).
2. Carefully pull the spark plug lead from the spark plug. Use a
socket wrench to remove the spark plug.
3. Install the new spark plug into the cylinder head. Tighten the
spark plug to 15 ft/lb.
4. Replace the spark plug lead, making sure it is fully seated.
5. Replace the spark plug cover.

LOCATION
TRANSPORTATION AND STORAGE
Transport or store the generator only if it has cooled completely.
Make sure the fuel valve and the vent on the fuel cap are both in
the OFF (“O”) position.
It is important to prevent gum deposits from forming in essential
fuel system parts such as the carburetor, fuel hose or tank during
long-term storage. Also, experience indicates that alcohol-blended
fuels (called gasohol, ethanol or methanol) can attract moisture,
which leads to separation and formation of acids; these acids in
gas can damage the fuel system of an engine while in storage.
To avoid engine problems, the use of a commercial fuel stabilizer
prior to storage is recommended. Follow the manufacturer’s
instructions when adding the fuel stabilizer.
If the generator is going to be stored for more than six (6) months,
the generator should be prepared as follows:
1. Remove all gasoline from the fuel tank.
2. Start and run engine until engine stops from lack of fuel or
open the valve on carburetor bowl (Figure 13), and allow
gasoline to drain down tube into a receptacle. Discard
appropriately. Be sure to close the valve once the gasoline has
drained.
3. After the engine cools down, drain oil from crankcase. Refill
with recommended grade.
4. Remove spark plug and pour about 1/2 ounce (15 ml) of
engine oil into the cylinder. Cover spark plug hole with rag. Pull
the starting rope several times to coat the cylinder walls with
engine oil.
5. Install and tighten the spark plug.
6. Clean the generator outer surfaces. Check that cooling air
slots and openings on generator are open and unobstructed.
7. Store the unit in a clean, dry place.
