High Altitude Operation - PowerLand PD210E Owner's Manual

cables will affect the weld. The correct polarity selection is dependent on the type of electrode you are
using and the type of material you are welding; refer to the electrode manufacturer's recommendations
for best results.
For straight polarity, attach the electrode cable to the negative terminal, and attach the ground cable
to the positive terminal. To reverse polarity, reverse the cables.

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 emissions. High altitude performance can be improved by specific
modifications to the carburetor. If you always operate your generator/welder at altitudes above 5,000
feet (1,500 meters), have an authorized our servicing dealer perform this carburetor modification. This
engine, when operated at high altitude with the carburetor modifications for high altitude use, will
meet each emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease about3.5% for each 1000-foot
(300-meter) increase in altitude.
The effect of altitude on horsepower will be greater than this if no carburetor modification is made.
NOTICE: When the carburetor has been modified for high altitude operation, the air fuel mixture will
be too lean for low altitude use.
Operation at altitude below 5000 feet (1,500 meters) with a modified carburetor may cause
the engine to overheat and result in serious engine damage. For use at low altitudes, have an
authorized our servicing d6aI8r return the carburetor to of original factory specification.
