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.
3. Ensure that the fuel petcock is open. The fuel petcock is open when the lever is perpendicular to the ground
(straight up and down as in Fig.12).
4. Check that the spark plug cap is securely attached to the spark plug.
5. Inspect the air filter. Clean or replace it if necessary.
6. Disconnect all electrical loads from the generator, and turn the engine switch on.
7. Follow the starting procedures in this manual on page11.
If the engine still does not start
1. Pull the starter handle 5-6 times.
2. Remove and inspect the spark plug.
If the spark plug is dry:
1. Ensure that there is fresh fuel in the tank and that the fuel petcock is open.
2. Reinstall the spark plug and spark plug cap.
3. Try to start the engine again by following the starting procedures in this manual on page11.
4. If the engine fails to start, take the generator to an authorized HITACHI service center.
If the spark plug is wet.
1. Clean, gap, or replace the spark plug.
2. Reinstall the spark plug and spark plug cap.
3. Try to start the engine again by following the starting procedures in this manual on page11.
4. If the engine fails to start, take the generator to an authorized HITACHI service center.
If there is no power to the receptacles
1. Turn the circuit breaker switches off and disconnect all electrical loads from the generator.
2. Turn the circuit breakers on and test the GFCI’s by following the procedures in this manual on page5.
3. Place the voltage selector to the 120 Volt only positions (unless you are using a tool that requires 240 Volts).
4. Turn the idle control switch off.
5. Turn the circuit breaker(s) off and reconnect the electrical loads. Be sure that the plugs are securely
connected to the receptacles.
6. Turn the circuit breaker(s) on.
7. If there is still no power at the receptacles, take the generator to an authorized HITACHI service center.
IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and trouble-free operation. It will also help reduce air
pollution.
