6. When finished checking the voltage, switch the generator's
main circuit breaker OFF and put the mode switch in the OFF
position to shut down the generator.
7. Make sure the 2-pole circuit breaker installed in the main
distribution panel is in the OFF position.
8. Use the transfer handle to move the main contacts in the
transfer switch to the UP (utility position). Switch the 2-pole
breaker ON in the distribution panel.
9. Now switch the generator's main breaker ON, and put the
mode switch in AUTO.
10. Shut OFF utility power and make sure the generator starts
automatically.

11. If everything worked properly, switch the main breaker to ON
and make sure that power is automatically transferred back to
the utility.
12. After the engine has completed its cool down cycle and shut
down, shut OFF utility power again.
When the generator is supplying power to the transfer switch,
move the breakers in the switch to the ON position, one at a
time, until the generator has accepted the entire priority load.
13. With the generator carrying the entire priority load, recheck
gas pressure to verify that it is at the same level it was before
the generator was started.
Even if the generator is running smoothly at
this point, a drop in gas pressure indicates that
the supply is barely adequate to supply the
generator's needs. Changes in the generator load,
or additional gas demand by other appliances
may affect the generator's performance. Verify
gas pressure and pipe sizing. Unhook the
manometer and reinstall the port plug.
