NOTE:
To make draining the oil easier, a 6” length of vinyl (PVC) hose
with an inside diameter of 1.25” (32mm) any be placed over
the drain lip.
3. Tip the generator upright once the oil has finished draining.
Replace the engine oil with the proper grade called out in
Section “ADDING ENGINE OIL”, then replace the drain plug.
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. 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 a NGK CR5H88 or Denso
U16FSR-UB that has be gapped to .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 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.
3. While engine is still warm, drain oil from crankcase. Refill with
recommended grade.
4. Remove spark plugs and pour about 1/2 ounce (15 ml) of
engine oil into the cylinders. 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.
Do not store gasoline from one season to another.
If possible, store the unit indoors and cover it to give protection
from dust and dirt.
