Air-cooled Generators
2.4 GENERATOR 
TESTS UNDER LOAD
To test the generator set with electrical loads applied, 
proceed as follows:
1.  Set generator’s main circuit breaker to its OFF 
(or OPEN) position.
2.  Turn OFF all breakers on the load center of the 
transfer box (T1 and T2).
3.  Set the generator's AUTO/OFF/MANUAL switch to 
OFF.
4.  Turn OFF the utility power supply to the transfer 
switch, using the means provided (such as a util-
ity main line circuit breaker).
  Do not attempt manual transfer switch opera-
tion until all power voltage supplies to the 
transfer switch have been positively turned off. 
Failure to turn off all power voltage supplies 
will result in extremely hazardous and possibly 
fatal electrical shock.
5.  Manually set the transfer switch to the STANDBY 
position, i.e., load terminals connected to the 
generator's E1/E2 terminals. The transfer switch 
operating lever should be down.
6.  Set the generator's AUTO/OFF/MANUAL switch 
to MANUAL. The engine should crank and start 
immediately.
7.  Let the engine stabilize and warm up for a few 
minutes.
8.  Set the generator’s main circuit breaker to its ON 
(or closed) position. Loads are now powered by 
the standby generator.
9.  Turn ON the load center of the transfer switch 
(T1 and T2).
10. Connect an accurate AC voltmeter and a frequen-
cy meter across terminal lugs E1 and E2.
• 7kW voltage should be greater than 230 volts and 
frequency should be greater than 58 Hz.
• 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.
