tory prior to being shipped and do not require any
type of break-in.
Before starting, complete the following:
1. Set the generator’s main circuit breaker to its
OFF (or OPEN) position.
2. Set the generator's AUTO/OFF/MANUAL switch to
the OFF position.
3. Turn OFF all breakers on the load center of the
transfer box (T1 and T2).
4. Turn OFF all loads connected to the transfer
switch terminals T1 and T2.
5. Check the engine crankcase oil level and, if neces-
sary, fill to the dipstick FULL mark with the rec-
ommended oil. Do not fill above the FULL mark.
ommended oil. Do not fill above the FULL mark.
6. Check the fuel supply. Gaseous fuel lines must
have been properly purged and leak tested in
accordance with applicable fuel-gas codes. All
fuel shutoff valves in the fuel supply lines must
be open.

fuel shutoff valves in the fuel supply lines must

During initial start up, after installation, it is normal
for the generator to exceed the normal number of
start attempts and experience an “over crank” fault.
This is due to accumulated air in the fuel system dur-
ing shipment.
for the generator to exceed the normal number of
start attempts and experience an “over crank” fault.
This is due to accumulated air in the fuel system dur-
ing shipment.
To reduce or eliminate this problem on initial start
up, remove the air filter cover and partially cover the
fuel mixer inlet while the engine is cranking (Figures
2.1 and 2.2). This will cause an abnormal vacuum
in the system and purge the air from the system.
Once fuel reaches the engine, it will begin to run.
Remove the blockage from the mixer inlet as soon
as the engine begins to fire. The unit should then be
run several minutes to insure that all air is removed
from the fuel system. Once the engine is running, this
procedure is not required as long as the fuel supply
to the generator is not interrupted. This procedure
will only be required if the generator becomes discon-
nected from the fuel system for whatever reason.

DANGER
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.
