• 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 fol-
lowing procedure 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.
The recommended battery is Group 27F, 12V nega-
tive ground, 700 CCA/90 AH minimum capacity. 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 nec-
essary to check the specific gravity or electrolyte level.
Have these procedures performed at the intervals
specified in Section 4, “Maintenance.” A negative
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, serv-
iced, 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 Section 4, “Maintenance.”
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” (Section 1.10) 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”
(Section 1.10) and “Engine Oil Recommendations”
(Section 1.14).
NOTE:
This engine is shipped from the manufacturer
with 5W-20 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”
(Section 1.10) and “Coolant” (Section 1.15).
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-
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.
