 Be sure the utility power supply is turned off
and the 7.5A fuse is removed from the generator
control panel, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
Servicing of the battery is to be performed or supervised by per-
sonnel knowledgeable of batteries and the required precautions.
Keep unauthorized personnel away from batteries.
See the Specifications section for the correct size and rating when
replacing the battery. Have these procedures performed at the
intervals specified in the "Service Schedule." A negative ground
system is used. Battery connections are shown on the wiring dia-
grams. Make sure the battery is correctly connected and terminals
are tight. Observe battery polarity when connecting the battery to
the generator set.

1.15 BATTERY CHARGER

These generators DO NOT contain an internal battery charger.
The manufacturer provides a battery trickle charger that is
active when the unit is set up for automatic operation. With
the battery installed and utility power source voltage available
to the transfer switch, the battery receives a trickle charge to
prevent self-discharge. The trickle charger is designed to help
extend the life of the battery by maintaining the battery. The
trickle charge feature cannot be used to recharge a discharged
battery.
For units shipped with a transfer switch/load center, the battery
charger is pre-installed in the transfer switch enclosure.
For units shipped without a transfer switch/load center, a separate
battery charger module is included with the generator.
(For battery charger installation, see the Generator Install Guidelines
and Battery Charger Instructions included with the unit.)
2.1 BEFORE INITIAL START-UP
These units have been run and tested at the factory prior to
being shipped and do not require any type of break-in.
This unit comes filled with oil from the factory. Check the oil
level and add the appropriate amount if necessary.
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.

NOTE:
5. Check the engine crankcase oil level and, if necessary, fill to
the dipstick FULL mark with the recommended 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.
During initial start up only, the generator may exceed the normal
number of start attempts and experience an "over crank" fault (See
the "Overcrank" section). This is due to accumulated air in the fuel
system during installation. Reset the control board and restart up
to two more times, if necessary. If unit fails to start, contact the
local dealer for assistance.

Never operate the engine with the oil level
below the "Add" mark on the dipstick. Doing this
could damage the engine.
2.2 CHECK TRANSFER SWITCH
OPERATION
Refer to the "Manual Transfer Operation" section, of the owner's
manual for procedures.
DANGER
 Do not attempt manual transfer switch operation
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 electri-
cal shock.
2.3

ELECTRICAL CHECKS

Complete electrical checks as follows:
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 on the utility power supply to the transfer switch using
the means provided (such as a utility main line circuit break-
er).
DANGER
 The transfer switch is now electrically "hot."
Contact with "hot" parts will result in extremely
hazardous and possibly fatal electrical shock.
Proceed with caution.
5. Use an accurate AC voltmeter to check utility power source
voltage across transfer switch terminals N1 and N2. Nominal
line-to-line voltage should be 240 volts AC.
