HIGH AND LOW TEMPERATURE OPERATION
Air temperature affects generator output. Output drops 1% for each 10°F temperature rise above 60° F. Very low temperature may cause the engine to be hard to start.
TROUBLESHOOTING
If the engine does not start
1.Check the fuel tank for sufficient fuel. Refill with fresh gasoline if necessary.
2.Check the engine oil. Fill to the upper limit with fresh oil.
