• 10, 13 & 16kW voltage should be greater than
240 volts and frequency should be greater than
60 Hz.
11. Let the generator run at full rated load for 20-30
minutes. Listen for unusual noises, vibration or
other indications of abnormal operation. Check
for oil leaks, evidence of overheating, etc.
12. When testing under load is complete, turn OFF
electrical loads.
13. Set the generator's main circuit breaker to its
OFF (or OPEN) position.
14. Let the engine run at no-load for a few minutes.
15. Set the AUTO/OFF/MANUAL switch to OFF. The
engine should shut down.
2.5 CHECKING AUTOMATIC
OPERATION
To check the system for proper automatic operation,
proceed as follows:
1. Set generator’s main circuit breaker to its OFF
(or OPEN) position.
2. Check that the AUTO/OFF/MANUAL switch is set
to OFF.
3. Turn OFF the utility power supply to the transfer
switch, using means provided (such as a utility
main line circuit breaker).
4. Manually set the transfer switch to the UTILITY
position, i.e., load terminals connected to the util-
ity power source side.
5. Turn ON the utility power supply to the transfer
switch, using the means provided (such as a util-
ity main line circuit breaker).
6. Set the generator's main circuit breaker to its ON
(or CLOSED)) position.
7. Set the AUTO/OFF/MANUAL switch to AUTO. The
system is now ready for automatic operation.
8. Turn OFF the utility power supply to the transfer
switch.
With the AUTO/OFF/MANUAL switch at AUTO, the
engine should crank and start when the utility source
power is turned OFF after a 10 second delay. After
starting, the transfer switch should connect load cir-
cuits to the standby side after a 15 second delay. Let
the system go through its entire automatic sequence
of operation.
With the generator running and loads powered by
generator AC output, turn ON the utility power supply
to the transfer switch. The following should occur:
After about 15 seconds, the switch should transfer
loads back to the utility power source.
About one minute after retransfer, the engine
should shut down.

2.6 ADJUSTING THE FUEL REGULATOR
- 7KW (NATURAL GAS ONLY)
NOTE:
All V-twin engine units DO NOT require a fuel reg-
ulator adjustment due to the fuel system design.
Although the generator has been factory set to pro-
vide maximum power, it may be necessary in some
areas to adjust this setting. If experiencing engine
problems at high or full load conditions, follow these
steps. It will require a frequency meter to perform
this procedure.
1. Turn off utility power to the main distribution
panel in the house. This can be done by switching
the service main breaker to the off or open posi-
tion.
2. Allow the generator to start. Before loading the
generator, confirm that the No Load Frequency,
with the roof open and door off, is set to 63-63.5
Hz. Transfer load to emergency circuits.
3. Turn on appliances, lights, pumps, etc., that are
on the emergency circuits in an attempt to fully
load the generator. Be cautious not to overload
the generator. Use the following chart as a guide:
4. When 3/4 load has been achieved. Connect a fre-
quency meter to the output lugs of the generator’s
main line circuit breaker.
5. The fuel regulator is fitted with one adjustment
screw. While watching the frequency meter, slowly
turn the adjustment screw clockwise or counter-
clockwise until the highest frequency is read on
the meter. Only limited adjustment is available
because of the set pin. Under no circumstances
should any of the pins be removed (Figure 2.3).
