Verify Engine Oil Level; Add Fuel - Briggs & Stratton Storm Responder 5500 Operator's Manual

Verify Engine Oil Level

The generator engine is shipped from the factory filled with
oil (API SJ or higher 10W-30). This allows for generator
operation in the widest range of temperature and climate
conditions. Before starting the engine, check oil level and
ensure that engine is serviced as described in Maintenance.
NOTICE Any attempt to crank or start the engine before it
has been properly filled with the recommended oil could
result in equipment failure.
• Refer to Maintenance for oil fill information.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
NOTICE See Oil in the Maintenance section to review oil
recomendations. Verify provided oil in engine is the correct
viscosity for current ambient temperature.

Add Fuel

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). For high
altitude use, see High Altitude.
• Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
NOTICE Avoid generator damage.
Failure to follow Operator's Manual for fuel
recommendations voids warranty.
• DO NOT use unapproved gasoline such as E85.
• DO NOT mix oil in gasoline.
• DO NOT modify engine to run on alternate fuels.
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).

WARNING Fuel and its vapors are extremely flammable
and explosive which could cause burns,
fire or explosion resulting in death,
serious injury and/or property damage.
WHEN ADDING FUEL
• Turn generator engine OFF and let it cool at least 2 minutes
before removing fuel cap. Loosen cap slowly to relieve pressure
in tank.
• Fill 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.
• Check fuel lines, tank, cap and fittings frequently for cracks or
leaks. Replace if necessary.
• DO NOT light a cigarette or smoke.
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 about 1.5" (4 cm) of tank
space (C) for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate before
starting engine.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum
85 octane / 85 AKI (89 RON) gasoline is acceptable. To
remain emissions compliant, high altitude adjustment is
required. Operation without this adjustment will cause
decreased performance, increased fuel consumption, and
increased emissions. See an authorized dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
kit is not recommended.
