Positioning; High Altitude Operation - Powermate PM0143250 Operator's Manual

POSITIONING

•
Place the generator set on a flat and solid surface to
prevent it from sinking.
• Keep fuel, oil or other explosives at a safe distance from
the generator set.
• Select a site that is well ventilated and protected from the
weather.
• Place the generator set safely away from people and
animals.

HIGH ALTITUDE OPERATION

HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air-fuel mixture
will be too rich. Performance will decrease and fuel
consumption will increase. A very rich mixture will also foul
the spark plug and cause hard starting. Operation at an
altitude that differs from that at which this engine was
certified, for extended periods of time, may increase emis-
sions.
High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your
engine at altitudes above 914 meters (3,000 feet), have your
authorized service center perform a carburetor modification.
HIGH ALTITUDE KIT PART NUMBER: 0071014
Even with a carburetor modification, engine horsepower
will decrease about 3.5% for each 300 meter (1,000 foot)
increase in altitude. The effect of altitude on horsepower will
be greater if no carburetor modification is made. A decrease
in engine horsepower will decrease the power output of the
generator.
When the carburetor has been modified for high
altitude operation, the air-fuel mixture will be too lean
for low altitude use. If the generator is used at low
altitudes after a carburetor modification, the
carburetor may cause the engine to overheat and result
in serious engine damage. For use at low altitudes,
have your authorized service center return the
carburetor to original factory specifications.
NOTICE: Warranty is Void if the necessary adjustments for
high altitude use are not made.
