Install the battery as described in Servicing the Battery in
the Maintenance section of the operator's manual. Always
make sure the NEGATIVE cable is connected last.
WARNING Battery posts, terminals and related
accessories contain lead and lead compounds - chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.

Fuel Supply System

Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.

Initial Start-up (No Load)

Before operating the generator or placing it into service,
inspect the entire installation carefully. Then begin testing the
system without any electrical loads connected, as follows:
NOTE: Unit has been set-up for NG or LP vapor operation at
the factory. Fuel conversion, if needed, must be completed
prior to performing these steps.
1. Connect an accurate AC voltmeter and a frequency
meter to check generator output at load side of
circuit breaker.
2. Set generator's main circuit breaker to its ON
(closed) position.
3. Confirm 15 Amp fuse is installed in system
control panel.
4. Set generator's system switch to AUTO.
16
5. Push and hold MANUAL OVER-RIDE button on control
panel for about six seconds. Engine will start.
NOTE: When the generator is started for the very first time, it
will require that air in the gaseous fuel lines be purged. This
may take a few minutes.
6. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil or coolant leaks
while engine runs.
7. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.
8. No-load voltage should be 239 - 244 Volts, frequency
should be 59.8 - 60.2 Hz.
NOTE: If AC voltage is outside these ranges, perform the
generator adjustment, Steps 11 and 12 below.
9. Check generator output between one of the generator
connection lugs and the neutral lug, then between the
other generator connection lug and the neutral lug. In
both cases, voltage reading should be 117 - 123 Volts.
IMPORTANT: DO NOT proceed until you are certain that
generator AC voltage is correct and within the stated limits.
Generator frequency is fixed and not adjustable.
10. If voltage and frequency values are correct, proceed to
step 13.
11. Connect voltmeter as described in step 1 above.
12. While observing voltmeter, adjust alternator voltage
control (A) for 240 volts. DO NOT adjust either of the
other alternator controls.

13. Push and hold MANUAL OVER-RIDE button on control
panel until engine stops.
14. Install alternator circuit breaker enclosure cover.
