Add Oil
CAUTION!
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.
• Use a long neck funnel OR remove the fuel tank as
described in "Fuel Tank", when adding or changing oil.
• Follow the oil grade recommendations and oil fill
instructions given in the engine owner's manual.
NOTE: The generator's revolving field rides on a
prelubricated and sealed ball bearing that requires no
additional lubrication for the life of the bearing.

Add Gasoline
• Use fresh, clean regular UNLEADED gasoline. Do Not
use premium gasoline. Do Not mix oil with gasoline.
Never use engine or carburetor cleaner products in the

fuel tank.

• Clean area around fuel fill and remove fuel cap/gauge.
• Slowly add gasoline to fuel tank. Allow about 1.5" of tank
space for fuel expansion (Figure 2).
Figure 2 — Typical Fuel Expansion Space
• Install fuel cap and permit any spilled gasoline to
evaporate.
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. Be
sure to review "Storage" on page 11.
Fuel Tank
As is common with all plastic fuel containers, the
removable fuel tank supplied with this generator may swell
or expand due to build-up of fuel vapors when the vent
knob is closed.This tank is designed and has been tested to
safely withstand pressure-buildup.The 'ballooning' condition
is relieved by turning the vent knob fully counterclockwise
or loosening and retightening the fuel cap/gauge.When
installing the tank on your generator, relieve tank pressure
before tightening the four large plastic wing nuts.
IMPORTANT: The vent knob should be closed whenever
you move the generator or transport the fuel tank.
