1. Place generator on a level surface (not to exceed 15° in any
direction).
2. Clean area around oil fill and remove oil fill cap and dipstick.
3. Wipe dipstick clean.
4. Slowly fill engine with oil through the oil fill opening until it
reaches the full mark on the dipstick. Stop filling occasionally to
check oil level. Be careful not to over fill.
5. Install oil fill cap and finger tighten securely.
6. Check engine oil level before starting each time thereafter.
2.6.2 ADDING GASOLINE
Never fill fuel tank indoors. Never fill fuel tank
when engine is running or hot. Allow engine
to cool entirely before filling fuel tank. Avoid
spilling gasoline on HOT engine. DO NOT light
a cigarette or smoke when filling the fuel tank.
Gasoline is highly flammable and its vapors are
explosive.
Do not overfill the fuel tank. Always leave room
for fuel expansion. If the fuel tank is overfilled,
fuel can overflow onto a HOT engine and cause
FIRE or EXPLOSION.
1. Use regular UNLEADED gasoline with the generator engine. Do
not use any gasoline with more than 10% added Ethanol, and
never use E85 gasoline. Do not mix oil with gasoline.
2. Clean area around fuel fill cap, remove cap.
3. Slowly add unleaded regular gasoline to fuel tank. Be careful
not to overfill (Figure 8).
4. Install fuel cap and wipe up any spilled gasoline.

DO NOT FILL ABOVE THE LIP!
IMPORTANT: It is important to prevent gum deposits from forming
in fuel system parts such as the carburetor, fuel hose or tank during
storage. 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. See the "Storage"
section. Never use engine or carburetor cleaner products in the fuel
tank as permanent damage may occur.
2.7 TO START THE ENGINE
Never start or stop engine with electrical
devices plugged into the receptacles AND
devices turned on.
1. Unplug all electrical loads from the unit's receptacles before
starting the engine.
2. Make sure the unit is in a level position (not to exceed 15° in any
direction).
3. Turn the Fuel Shut-off Valve to the "ON" position (Figure 9).
4. Turn engine ON/OFF switch to ON position (Figure 9).
5. Move engine CHOKE lever to the START position (Figure 10).
6. To start engine, firmly grasp the recoil handle and pull slowly until
increased resistance is felt. Pull rapidly up and away.
7. When engine starts, move choke lever to 1/2-CHOKE position
until engine runs smoothly and then fully into RUN position. If
engine falters, move choke back out to 1/2-CHOKE position until
engine runs smoothly and then to RUN position.
NOTE:
If engine fires, but does not continue to run, move choke lever to
the START position and repeat starting instructions.
