iii. Allow starter cord to return slowly.
5. When engine starts, move choke lever to RUN position.
6. Under long, continuous-run operating conditions, be prepared to:
a. Check and refuel the engine on a regular basis. A tank of gas should last about 9.5 hours
under 50% load.
⚠WARNING
A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if engine is running or
still hot. Let cool at least 2 minutes.
b. Check engine oil level each time you refuel.
c. Change oil after the first 20 operating hours, and at least every 100 operating hours
thereafter, as directed in the engine owner's manual.
⚠WARNING
Never open oil port while engine is running. Hot oil can spray over face and body.
Checking Generator Output
Although the speed of the engine was carefully adjusted at the factory so that the generator produces
the proper voltage and frequency, output voltage should be checked periodically to ensure the
generator is working properly before connecting loads to the generator.
⚠WARNING
The generator must be run at the correct speed in order to produce the proper electrical voltage and
frequency. Failure to do so could result in damage to equipment powered by the generator and
possible injury to the individual.
Output voltage should be checked with a portable voltage meter:
1. Start engine and allow to warm up for five minutes. Do not connect any loads.
2. Use voltage meter to check output voltage at the generator’s outlets/receptacles.
3. Measured voltage should be within the following ranges:
a. 120V +/- 10% at 120V receptacles.
b. 240V +/- 10% at 240V receptacles.
4. If measured voltage is not within the specified range, have generator adjusted by factory
authorized personnel. Do not attempt to adjust the engine speed yourself.
Note: There is a slight variation in voltage/speed with changing electrical loads. All engines have a
tendency to slow down when a load is applied. When electrical loads are connected to the generator,
the engine is more heavily loaded and as a result, the speed drops slightly.
This slight decrease in speed, together with the voltage drop within the generator itself, results in a
slightly lower voltage when the generator is loaded to its full capacity than when it is running with no
load. Additionally, there may be small brief surges and drops in voltage as motors connected to the
