WARNING
POISONOUS GAS HAZARD.
Engine exhaust contains carbon monoxide, 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.
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.
•
•Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms
with battery back-up according to the manufacturer’s instructions. Smoke alarms
cannot detect carbon monoxide gas.
•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

Operation at High Altitude
The density of air at high altitude is lower than at sea level. Engine power is
reduced as the air mass and air-fuel ratio decrease. Engine power and generator
output will be reduced approximately 3% for every 1000 feet of elevation above sea
level. This is a natural trend and cannot be changed by adjusting the engine. At
high altitudes increased exhaust emissions can also result due to the increased
enrichment of the air fuel ratio.
Other high altitude issues can include hard starting, increased fuel consumption
and spark plug fouling. To alleviate high altitude issues other than the natural
power loss, FIRMAN can provide a high altitude carburetor main jet.The alternative
main jet and installation instructions can be obtained by contacting Customer
Support. Installation instructions are also available in the Technical Bulletin area of
the FIRMAN internet site.
Operation using the alternative main jet at elevations lower than the recommended
minimum altitude can damage the engine. For operation at lower elevations, the
standard main jet must be used. Operating the engine with the wrong engine
configuration at a given altitude may increase its emissions and decrease fuel
efficiency and performance.
WARNING

STOPPING THE GENERATOR
CLOSE
(a) Turn off the power switch of the electric
equipment or unplug the cord from receptacle
of the generator.
(b) Allow the engine about 3 minutes to cool
down at no-load before stopping.
(c) Set the engine switch to "OFF" position.
(d) Close (stop) the fuel lever.
