Select the oil’s viscosity grade according to your
expected operating temperature:
• Connect the black battery cable to the negative (-)
battery terminal {Figure 4).
• Connect the other end of the black cable to the

BEFORE STARTING THE
ENGINE
Perform the following tasks before trying to start the
generator engine:
Add Engine Oil____________________
NOTE: In the future, When adding oil to the engine
crankcase use only high quality detergent oil rated
with API service classification SF and SG. Use no
special additives.
DO NOT USE SAE 10W -40.

Although multi-viscosity oils (5W30, 10W30, etc.)
improve starting in cold weather, these multi-viscosity
oils will result in increased oil consumption when used
above 32°F. Check your engine oil level frequently to
avoid possible damage from running low on oil. See
the engine owner’s manual for further information.
To add oil to the engine:
• Place generator on a level surface.
• Clean area around oil fill and remove oil cap.
• Slowly add oil through the oil fill opening until it
reaches the top. DO NOT OVERFILL.
• Install oil cap, hand tighten securely.
A
CAUTION: Any attempt to crank or start the
engine before it has been properly serviced
with the recommended oil will result in an
engine failure.
NOTE: The generator’s revolving field rides on a pre­
lubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.
Add Fuel

A
DANGER: NEVER fill fuel tank indoors.
NEVER fill fuel tank when engine is running or
hot.
Do Not light a cigarette or smoke when
filling the fuel tank.
CAUTION: Do Not overfill the fuel tank.
Always allow room for fuel expansion.
Use only regular UNLEADED gasoline.
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, 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.
