• 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.

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.

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).
