•  Spilled electrolyte is to be washed down with an 

acid-neutralizing agent. A common practice is to 
use a solution of one pound (500 grams) bicarbon-
ate of soda to one gallon (4 liters) of water. The 
bicarbonate 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 following pro-
cedure are to be followed:

•  DO NOT SMOKE when near batteries,
•  DO NOT cause flame or spark in battery area, and
•  Discharge static electricity from body before touch-

ing batteries by first touching a grounded metal 
surface.

Servicing of batteries is to be performed or super-
vised by personnel knowledgeable of batteries and 
the required precautions. Keep unauthorized person-
nel away from batteries.

For recommended batteries, see the Maintenance 
section. All batteries must be at 100 percent state-of-
charge before they are installed on the generator.

When using maintenance-free batteries, it is not 
necessary to check the specific gravity or electrolyte 
level. Have these procedures performed at the inter-
vals specified in the Maintenance section. A nega-
tive ground system is used. Battery connections are 
shown on the wiring diagrams. Make sure all batter-
ies are correctly connected and terminals are tight. 
Observe battery polarity when connecting batteries to 
the generator set.

NOTE:

Damage will result if the battery connections are 
made in reverse.

2.11 PREPARATION BEFORE START-UP

The instructions in this section assume that the 
standby generator has been properly installed, ser-
viced, tested, adjusted and otherwise prepared for 
use by a competent, qualified installation contractor. 
Be sure to read the “Safety Rules” on pages 2 and 3, 
as well as all other safety information in this manual, 
before attempting to operate this (and related) equip-
ment.

2.11.1  PRIOR TO INITIAL START-UP

  Prior to initially starting the generator, it must 

be properly prepared for use. Any attempt to 
crank or start the engine before it has been 
properly serviced with the recommended types 
and quantities of engine fluids (oil, coolant, fuel, 
etc.) may result in an engine failure.

‹

Before starting the generator for the first time, the 
installer must complete the following procedures. For 
follow-up maintenance information and/or service 
intervals, please refer to the Maintenance section.

2.11.2 TRANSFER SWITCH

If this generator is used to supply power to any elec-
trical system normally powered by an electric utility, 
the National Electrical Code requires that a transfer 
switch be installed. The transfer switch prevents elec-
trical backfeed between two different electrical sys-
tems (for additional information, see the applicable 
transfer switch manual for this unit). The transfer 
switch, as well as the generator and other standby 
components, must be properly located and mounted 
in strict compliance with applicable codes, standards 
and regulations.

2.11.3 FUEL SYSTEM

Make sure the fuel supply system to the generator (a) 
delivers the correct fuel at the correct pressure and (b) 
is properly purged and leak tested according to code. 
No fuel leakage is permitted. See “Specifications” for 
more information.

2.11.4  GENERATOR SET LUBRICATION

Check the engine crankcase oil level before operating 
and add oil to the proper level – the dipstick “FULL” 
mark. Never operate the engine with the oil level 
below the dipstick “ADD” mark. See “Specifications” 
and “Engine Oil Recommendations”.

NOTE:

This engine is shipped from the manufacturer 
with 15W-40 oil. This oil should be changed after 
30 hours of operation.

2.11.5 ENGINE COOLANT

Have the engine cooling system properly filled with 
the recommended coolant mixture. Check the system 
for leaks and other problems. See “Specifications” 
and “Coolant”.

2.11.6 BELT TENSION

Check-the engine-fan belt tension and condition prior 
to placing the unit into service and at recommended 
intervals. Belt tension is correct when a force of 
approximately 22 pounds (10 kg), applied midway 
between pulleys, deflects the belt about 3/8- to 5/8 of 
an inch (10 to 16 mm).

2.11.7 ELECTRICAL SYSTEM

Make sure the generator is properly connected to an 
approved earth ground and/or ground rod.
