5. Install e-ring with pliers, squeezing from top of
e-ring to bottom of axle.
6. Repeat steps 4 and 5 to secure second wheel.
7. Tip generator so that engine side is down.
8. Line up holes in support leg (E) with holes in
generator frame.
9. Attach support leg using 2 capscrews (M8 x 16
mm) (F) and 2 hex nuts (G). Tighten with a
13 mm socket wrench and 13 mm wrench.
10. Return generator to normal operating position
(resting on wheels and support leg).
Add Engine Oil
1. Place generator on a flat, level surface.
2. Clean area around oil fill and remove yellow oil fill
cap.
NOTE: See the section Oil to review oil
recommendations. Verify provided oil bottle is correct
viscosity for current ambient temperature.
3. Using oil funnel (optional), slowly pour contents of
provided oil bottle into oil fill opening.
4. Replace oil fill cap and fully tighten.
Add Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High
altitude use, see below.
• Gasoline with up to 10% ethanol (gasohol) or up
to 15% MTBE (methyl tertiary butyl ether) is
acceptable.
To protect the fuel system from gum formation, mix in
a fuel stabilizer when adding fuel. See Storage. All
fuel is not the same. If you experience starting or
performance problems after using fuel, switch to a
different fuel provider or change brands. This engine
is certified to operate on gasoline. The emission
control system for this engine is EM (Engine
Modifications).
1. Clean area around fuel fill cap, remove cap.
2. Slowly add unleaded gasoline (A) to fuel tank (B).
Be careful not to overfill. Allow at least 1.5" (4 cm)
of tank space (C) for fuel expansion, as shown in
Figure 2.
3. Install fuel cap and let any spilled fuel evaporate
before starting engine.
High Altitude
At higher altitudes (over 5,000 feet), 85 octane/85 AKI
(89 RON) gasoline is recommended. High-altitude use
may require a carburetor jet kit to improve
performance and decrease fuel consumption. See an
Authorized Briggs & Stratton Dealer for more
information.
When adding fuel:
• Turn generator OFF and let it cool at least 2 minutes before
removing fuel cap. Loosen cap slowly to relieve pressure in
tank.
• Fill or drain fuel tank outdoors.
• DO NOT overfill tank. Allow space for fuel expansion.
• If fuel spills, wait until it evaporates before starting engine.
• Keep fuel away from sparks, open flames, pilot lights, heat,
and other ignition sources.
• DO NOT light a cigarette or smoke.
Fuel and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe burns
or death.

NOTICE
• DO NOT attempt to crank or start the engine before it has
been properly serviced with the recommended oil. This may
result in an engine failure.
Improper treatment of generator can damage it and
shorten its life.
NOTICE
• DO NOT use unapproved gasoline such as E85.
• DO NOT mix oil in fuel.
• DO NOT modify engine to run on alternate fuels.
Avoid generator damage.
Failure to follow Operator’s Manual for fuel
reccomendations voids warranty.
