engine break-in before using synthetic oil.
.
1. Place generator on a level surface.
2. Remove the Left Side Service Cover.
3. Remove oil fill cap (A) located on bottom
of engine crankcase. See Figure 2-4.
4. Add recommended engine oil. The full
level is the base of the threads in the filler
neck (B). DO NOT OVERFILL!
5. Replace oil fill cap and hand-tighten.
Figure 2-4. Add Engine Oil
Fuel
Fuel requirements are as follows:
• Clean, fresh, unleaded gasoline.
• Minimum rating of 87 octane/87 AKI (91
RON).
• Up to 10% ethanol (gasohol) is acceptable
(where available; non-ethanol-premium fuel
is recommended).
• DO NOT use E85.
• DO NOT use a gas oil mix.
• DO NOT modify engine to run on alternate
fuels. Stabilize fuel prior to storage.
1. Verify unit is OFF and cooled for a mini-
mum of two minutes prior to fueling.
2. Place unit on level ground in a well venti-
lated area.
3. Clean area around fuel cap and remove
cap slowly (A). See Figure 2-5.

Figure 2-5. Add Recommended Fuel
NOTE: Allow spilled fuel to evaporate before
starting unit.
IMPORTANT NOTE: It is important to pre-
vent 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.

Prepare Generator for Use
Know Generator Limits
Overloading a generator can result in damage
to the generator and connected electrical
devices. Observe the following to prevent
overload:
• Add up the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the gener-
ator's wattage capacity.
• The rated wattage of lights can be taken
from light bulbs. The rated wattage of tools,
appliances, and motors can be found on a
data label or decal affixed to the device.
• If the appliance, tool, or motor does not
give wattage, multiply volts times ampere
rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction
types, require about three times more watts
of power for starting than for running. This
surge of power lasts only a few seconds
when starting such motors. Make sure to
allow for high starting wattage when select-
ing electrical devices to connect to the gen-
erator:
1. Figure the watts needed to start the largest
motor.
2. Add to that figure the running watts of all
other connected loads.
The Wattage Reference Guide is provided to
assist in determining how many items the gen-
erator can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.
