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 a Briggs & Stratton 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.
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 GFCI, 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 (A) 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.
A
• 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.
