3. Install fuel cap and let any spilled fuel evaporate
before starting engine.
High Altitude
At altitudes over 1524 m (5,000 ft.), 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 a Briggs & Stratton Authorized Dealer for high
altitude adjustment information. Operation of the
engine at altitudes below 762 m (2,500 ft.) with the
high altitude kit is not recommended.
Fuel Tank Cap Vent Lever
The fuel tank cap is provided with a vent lever (A) to
seal the fuel tank. The vent lever must be in the ON (I)
position for the engine to run.
A
When the engine is not in use, leave the vent lever in
the OFF (0) position to reduce the possibility of fuel
leakage. Allow the engine to cool before turning the
vent lever to the OFF (0) position.
Grounding Fastener
The generator neutral is floating, which means that
the AC stator winding is isolated from the grounding
fastener and the AC receptacle ground pins. On a
floating neutral generator the AC receptacle ground
pins are not functional. Electrical devices, such as a
residual current device (RCD), requiring a functioning
AC receptacle ground pin will not operate.
Special Requirements
There may be Federal, local codes, or ordinances that
apply to the intended use of the generator. Please
consult a qualified electrician, electrical inspector, or
the local agency having jurisdiction:
• This generator has a floating neutral and is not for
use on job sites requiring a bonded neutral.
Portable Generator Location
Before starting the portable generator there are two equally
important safety concerns regarding carbon monoxide
(CO) poisoning and fire that must be addressed.
NOTICE Satisfying the RISK OF CARBON MONOXIDE
POISONING location requirements may not satisfy the
fire location requirements. Satisfying the RISK OF FIRE
location requirements may not satisfy the CARBON
MONOXIDE POISONING location requirements.
Operation Location of Portable Generator to
REDUCE THE RISK OF CARBON MONOXIDE
POISONING
All fossil fuel burning equipment, such as a portable
generator, contains carbon monoxide (CO) gas in the
engine exhaust, a poisonous gas that could kill you in
minutes. You CANNOT smell it, see it, or taste it. Even
if you do not smell exhaust fumes, you could still be
exposed to carbon monoxide gas. The following must
be completed prior to starting the portable generator
engine:
• By law it is required in many states to have a
Carbon Monoxide (CO) alarm (B) in operating
condition in your home. Install/maintain battery-
operated carbon monoxide alarms or plug-in
carbon monoxide alarms with battery back-up
according to the manufacturer's instructions. A
CO alarm is an electronic device that detects
hazardous levels of CO. When there is a buildup
of CO, the alarm will alert the occupants by
flashing visual indicator light and alarm. Smoke
alarms cannot detect CO gas.
B
• Operate this product ONLY outside far away from
windows, doors and vents to reduce the risk of
carbon monoxide gas from accumulating and
potentially being drawn towards occupied spaces.
• DO NOT run this product inside homes, garages,
basements, crawlspaces, sheds, or other partially-
enclosed spaces even if using fans or opening
doors and windows for ventilation. Carbon
monoxide can quickly build up in these spaces
and can linger for hours, even after this product
has shut off.
• Your neighbor(s) home may be exposed to the
engine exhaust from your portable generator and
must be considered when deciding on a location
for the safe operation of your portable generator.
• ALWAYS place this product downwind and point
the engine exhaust away from occupied spaces.
If you start to feel sick, dizzy, or weak while using this
product, get to fresh air RIGHT AWAY. See a doctor.
You may have carbon monoxide poisoning.
