BEFORE STARTING ENGINE

Add Oil
WARNING!
Any attempt to crank or start the
engine before it has been properly filled with the
recommended oil may result in an engine failure.
To fill your engine with oil:
• Place generator on a level surface.
• Clean area around oil fill and remove oil fill cap.
• Select the oil's viscosity grade and fill engine with oil
following the instructions given in the engine owner's
manual. Do Not overfill!
• Install oil fill cap.
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 Gasoline

• Use regular UNLEADED gasoline with the generator
engine. Do Not use premium gasoline. Do Not mix oil
with gasoline.
• Clean area around fuel fill cap, remove cap.
• Slowly add unleaded regular gasoline to fuel tank. Be
careful not to overfill. Allow about 1/2" of tank space for
fuel expansion (Figure 2).
Figure 2 — Typical Fuel Expansion Space
• Install fuel cap and wipe up any spilled 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.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See "Storage"
on page 11. Never use engine or carburetor cleaner
products in the fuel tank as permanent damage may occur.
