use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) of water. The bicar-
bonate of soda solution is to be added until the
evidence of reaction (foaming) has ceased. The
resulting liquid is to be flushed with water and the
area dried.

Lead-acid batteries present a risk of fire because
they generate hydrogen gas. The

2.1 BEFORE
INITIAL
START-UP
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 the utility power supply to the transfer
switch using the means provided (such as the
utility main line circuit breaker).

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.

Never operate the engine with the oil level
below the “ADD” mark on the dipstick. Doing
this could damage the engine.

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.

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 loads connected to the transfer
switch terminals T1 and T2.
4. Turn on the utility power supply to the transfer
switch using the means provided (such as a utility

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 ter-
minals N1 and N2. Nominal line-to-line voltage
should be 240 volts AC.

across terminal N2 and neutral. Nominal line-to-
neutral voltage should be 120 volts AC.

turn OFF the utility power supply to the transfer
switch.
