** Operating Temperature Range: -18 deg. C (0 deg. F) to 40 Deg. C (104 Deg. F). When operated above 25 deg. C
(77 deg. F) there may be a decrease in power.
** Maximum wattage and current are subject to, and limited by, such factors as fuel Btu content, ambient tempera-
ture, altitude, engine condition, etc.. Maximum power decreases about 3.5% for each 1,000 feet above sea level;
and will also decrease about 1% for each 6° C (10° F) above 16° C (60° F) ambient temperature.
