Study these SAFETY RULES carefully before install-
ing, operating or servicing this equipment. Become
familiar with this Owner’s Manual and with the unit.
The generator can operate safely, efficiently and reli-
ably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to
follow simple and fundamental rules or precautions.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warn-
ings in this manual, and on tags and decals affixed
to the unit are, therefore, not all inclusive. If a pro-
cedure, work method or operating technique is used
that the manufacturer does not specifically recom-
mend, ensure that it is safe for others. Also make
sure the procedure, work method or operating tech-
nique utilized does not render the generator unsafe.
DANGER
Despite the safe design of this generator,
operating this equipment imprudently, neglect-
ing its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to install, operate or main-
tain this equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.
GENERAL HAZARDS
• For safety reasons, the manufacturer recommends
that this equipment be installed, serviced and
repaired by an Authorized Service Dealer or other
competent, qualified electrician or installation tech-
nician who is familiar with applicable codes, stan-
dards and regulations. The operator also must
comply with all such codes, standards and regula-
tions.
• Installation, operation, servicing and repair of this
(and related) equipment must always comply with
applicable codes, standards, laws and regulations.
Adhere strictly to local, state and national electri-
cal and building codes. Comply with regulations
the Occupational Safety and Health Administration
(OSHA) has established. Also, ensure that the
generator is installed, operated and serviced in
accordance with the manufacturer’s instructions
and recommendations. Following installation, do
nothing that might render the unit unsafe or in
noncompliance with the aforementioned codes,
standards, laws and regulations.
• The engine exhaust fumes contain carbon monox-
ide gas, which can be DEADLY. This dangerous gas,
if breathed in sufficient concentrations, can cause
unconsciousness or even death. For that reason,
adequate ventilation must be provided. Exhaust
gases must be piped safely away from any building
or enclosure that houses the generator to an area
where people, animals, etc., will not be harmed.
This exhaust system must be installed properly, in
strict compliance with applicable codes and stan-
dards.
• Keep hands, feet, clothing, etc., away from drive
belts, fans, and other moving or hot parts. Never
remove any drive belt or fan guard while the unit
is operating.
• Adequate, unobstructed flow of cooling and venti-
lating air is critical in any room or building hous-
ing the generator to prevent buildup of explosive
gases and to ensure correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seri-
ously affect safe operation of the generator.
• Keep the area around the generator clean and
uncluttered. Remove any materials that could
become hazardous.
• When working on this equipment, remain alert
at all times. Never work on the equipment when
physically or mentally fatigued.
• Inspect the generator regularly, and promptly
repair or replace all worn, damaged or defective
parts using only factory-approved parts.
SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe
operation be copied and posted in potential hazard areas. Safety should be stressed to all
operators, potential operators, and service and repair technicians for this equipment.
The engine exhaust from this product
contains chemicals known to the state
of California to cause cancer, birth
defects or other reproductive harm.

![](asset-4.png)
• Before performing any maintenance on the gen-
erator, disconnect its battery cables to prevent
accidental start-up. Disconnect the cable from the
battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• Never use the generator or any of its parts as a
step. Stepping on the unit can stress and break
parts, and may result in dangerous operating con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.
ELECTRICAL HAZARDS
• All generators covered by this manual produce
dangerous electrical voltages and can cause fatal
electrical shock. Utility power delivers extremely
high and dangerous voltages to the transfer switch
as well as the standby generator. Avoid contact
with bare wires, terminals, connections, etc., on
the generator as well as the transfer switch, if
applicable. Ensure all appropriate covers, guards
and barriers are in place before operating the gen-
erator. If work must be done around an operating
unit, stand on an insulated, dry surface to reduce
shock hazard.
• Do not handle any kind of electrical device while
standing in water, while barefoot, or while hands or
feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
• If personnel must stand on metal or concrete while
installing, operating, servicing, adjusting or repair-
ing this equipment, place insulative mats over a
dry wooden platform. Work on the equipment only
while standing on such insulative mats.
• The National Electrical Code (NEC) requires the
frame and external electrically conductive parts
of the generator to be connected to an approved
earth ground. This grounding will help prevent
dangerous electrical shock that might be caused
by a ground fault condition in the generator set or
by static electricity. Never disconnect the ground
wire.
• Wire gauge sizes of electrical wiring, cables and
cord sets must be adequate to handle the maxi-
mum electrical current (ampacity) to which they
will be subjected.
• Before installing or servicing this (and related)
equipment, make sure that all power voltage
supplies are positively turned off at their source.
Failure to do so will result in hazardous and pos-
sibly fatal electrical shock.
• Connecting this unit to an electrical system nor-
mally supplied by an electric utility shall be by
means of a transfer switch so as to isolate the
generator electric system from the electric utility
distribution system when the generator is operat-
ing. Failure to isolate the two electric system power
sources from each other by such means will result
in damage to the generator and may also result
in injury or death to utility power workers due to
backfeed of electrical energy.
• Generators installed with an automatic transfer
switch will crank and start automatically when
normal (utility) source voltage is removed or is
below an acceptable preset level. To prevent such
automatic start-up and possible injury to person-
nel, disable the generator’s automatic start circuit
(battery cables, etc.) before working on or around
the unit. Then, place a “Do Not Operate” tag on
the generator control panel and on the transfer
switch.
• In case of accident caused by electric shock, imme-
diately shut down the source of electrical power.
If this is not possible, attempt to free the victim
from the live conductor. AVOID DIRECT CONTACT
WITH THE VICTIM. Use a nonconducting imple-
ment, such as a dry rope or board, to free the vic-
tim from the live conductor. If the victim is uncon-
scious, apply first aid and get immediate medical
help.
• Never wear jewelry when working on this equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com-
ponents causing injury.
FIRE HAZARDS
• Keep a fire extinguisher near the generator at all
times. Do NOT use any carbon tetra-chloride type
extinguisher. Its fumes are toxic, and the liquid
can deteriorate wiring insulation. Keep the extin-
guisher properly charged and be familiar with its
use. If there are any questions pertaining to fire
extinguishers, consult the local fire department.
EXPLOSION HAZARDS
• Properly ventilate any room or building housing
the generator to prevent build-up of explosive gas.
• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com-
bustible materials are left in the generator com-
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround-
ing the generator clean and free from debris.
• These generator sets may operate using one of
several types of fuels. All fuel types are potentially
FLAMMABLE and/or EXPLOSIVE and should be
handled with care. Comply with all laws regulat-
ing the storage and handling of fuels. Inspect the
unit’s fuel system frequently and correct any leaks
immediately. Fuel supply lines must be prop-
erly installed, purged and leak tested according to
applicable fuel-gas codes before placing this equip-
ment into service.
• Diesel fuels are highly FLAMMABLE. Gaseous
fluids such as natural gas and liquid propane
(LP) gas are extremely EXPLOSIVE. Natural gas
is lighter than air, and LP gas is heavier than air;
install leak detectors accordingly.

EQUIPMENT DESCRIPTION
This equipment is a revolving field, alternating cur-
rent generator set. It is powered by a gaseous fueled
engine operating at 1800 rpm for 4-pole direct drive
units, 3600 rpm for 2-pole direct drive units and
2300 - 3000 rpm for quiet drive gear units. See the
Specifications section for exact numbers. The unit
comes complete with a sound attenuated enclosure,
internally mounted muffler, control console, main-
line circuit breaker, battery charger, and protective
alarms as explained in the following paragraph.
All AC connections, including the power leads from
the alternator, 120 volt battery charger input and
control connections to the transfer switch are avail-
able in the main connection box.
The generator incorporates the following generator
features:
• Rotor and Stator insulation is Class F rated as
defined by NEMA MG1-32.6, NEMA MG1-1.66.
The generator is self ventilated and drip-proof con-
structed.
• The voltage waveform deviation, total harmonic
content of the AC waveform and telephone influ-
ence factor have been evaluated and are acceptable
according to NEMA MG1-32.
ENGINE OIL RECOMMENDATIONS
The unit has been filled with 15W-40 engine oil at
the factory. Use a high-quality detergent oil classified
“For Service CC, SD, SE, SF.” Detergent oils keep the
engine cleaner and reduce carbon deposits. Use oil
having the following SAE viscosity rating, based on
the ambient temperature range anticipated before the
next oil change:
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
NOTE:
For temperatures below 32° F, it is strongly recom-
mended to use the optional Cold Weather Start Kit
(part number listed in the Specification Section).
The oil grade for temperatures below 32° F is 5W-
30 synthetic oil.
COOLANT RECOMMENDATIONS
Use a mixture of half low silicate ethylene glycol
base anti-freeze and deionized water. Cooling system
capacity is listed in the specifications. Use only deion-
ized water and only low silicate anti-freeze. If desired,
add a high quality rust inhibitor to the recommended
coolant mixture. When adding coolant, always add
the recommended 50-50 mixture.
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
mium hydroxide (“green slime”) forms and will
cause overheating. Engines that have been oper-
ated with a chromate base rust inhibitor must
be chemically cleaned before adding ethylene
glycol base anti-freeze. Using any high silicate
anti-freeze boosters or additives will also cause
overheating. The manufacturer also recommends
that any soluble oil inhibitor is NOT used for this
equipment.
DANGER
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
Ethylene glycol base antifreeze is poisonous.
Do not use mouth to siphon coolant from the
radiator, recovery bottle or any container. Wash
hands thoroughly after handling. Never store
used antifreeze in an open container because
animals are attracted to the smell and taste of
antifreeze even though it is poisonous to them.
Temperature Oil Grade (Recommended)
Above 80° F (27° C) SAE 30W or 15W-40
32° to 80° F (0° to 27° C) SAE 20W-20 or 15W-40
Below 32° F (0° C) See Note

![](asset-8.png)
ENGINE PROTECTIVE DEVICES
The standby generator may be required to operate for
long periods of time without an operator on hand to
monitor such engine conditions as coolant tempera-
ture, oil pressure or rpm. For that reason, the engine
has several devices designed to protect it against
potentially damaging conditions by automatically
shutting down the unit when the oil pressure is too
low, the coolant temperature is too high, the coolant
level is too low, or the engine is running too fast.
NOTE:
Engine protective switches and sensors are men-
tioned here for the reader’s convenience. Also
refer to the applicable control panel manual for
additional automatic engine shutdown informa-
tion.
HIGH COOLANT TEMPERATURE SWITCH
This switches contacts close if the temperature should
exceed approximately 140° C (284° F), initiating an
engine shutdown. The generator will automatically
restart and the LED will reset once the temperature
has returned to a safe operating level.
LOW COOLANT LEVEL SENSOR
Should the engine coolant level drop below the level
of the high coolant temperature switch, it is possible
for the engine to overheat without automatic shut-
down. To prevent such overheating, the engine has a
low coolant level sensor. If the level of engine coolant
drops below the level of the low coolant level sensor,
the engine automatically shuts down.
LOW OIL PRESSURE SWITCH
This switch has normally closed contacts that are
held open by engine oil pressure during cranking and
operating. Should oil pressure drop below the 8 psi
range, switch contacts close, and the engine shuts
down. The unit should not be restarted until oil is
added, and the AUTO/OFF/MANUAL switch must be
turned to OFF and then back to AUTO.
OVERCRANK SHUTDOWN
After a prespecified duration of cranking, this func-
tion ends the cranking if the engine has failed to
start. The overcrank LED will turn ON. Turn OFF the
AUTO/OFF/MANUAL switch, then turn switch back to
AUTO to reset the generator control board.
NOTE:
If the fault is not corrected, the overcrank feature
will continue to activate.
Approximate Crank Cycle Times
• 15 seconds ON
• 7 seconds OFF
• 7 seconds ON
• 7 seconds OFF
• Repeat for 45 seconds
Approximately 90 seconds total.
OVERSPEED SHUTDOWN
A speed circuit controls engine cranking, start-up,
operation and shutdown. Engine speed signals are
delivered to the circuit board whenever the unit is
running. Should the engine overspeed above a safe,
preset value, the circuit board initiates an automatic
engine shutdown. Contact the nearest Authorized
Dealer if this failure occurs.
RPM SENSOR LOSS SHUTDOWN
If the speed signal to the control panel is lost, engine
shutdown will occur.
DC FUSE
This fuse is located inside of the control panel. It
protects the panel wiring and components from
damaging overload. Always remove this fuse before
commencing work on the generator. The unit will
not start or crank if the fuse is blown. Replace the
fuse with one of the same size, type, and rating. (See
the exploded views and parts lists at the end of this
manual for replacement part number.)

FUEL SYSTEM
FUEL REQUIREMENTS
The standby generator may be equipped with one of
the following fuel systems:
• Natural gas fuel system
• Propane vapor (PV) fuel system
The Manual Drawing Listing that is affixed to the
unit includes the “Identification Code,” which may be
used to identify the type of fuel system installed on
the unit.
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is 5 inches
to 14 inches water column (0.18 to 0.5 psi); and
for liquid propane, 5 inches to 14 inches of water
column (0.18 to 0.5 psi).
NOTE:
Any piping used to connect the generator to the
fuel supply should be of adequate size to ensure
the fuel pressure NEVER drops below five inches
water column for natural gas or 5 inches water
column for propane vapor for all load ranges.
NOTE:
It is the responsibility of the installer to make sure
that only the correct recommended fuel is sup-
plied to the generator fuel system. Thereafter, the
owner/operator must make certain that only the
proper fuel is supplied.
NATURAL GAS FUEL SYSTEM
Natural gas is supplied in its vapor state. In most
cases, the gas distribution company provides piping
from the main gas distribution line to the standby
generator site. The following information applies to
natural gas fuel systems.
• Gas pressure in a building is usually regulated by
national, state and local codes.
• To reduce gas pressure to a safe level before
the gas enters a building, a primary regulator is
needed. The natural gas supplier may or may not
supply such a regulator.
• It is the responsibility of the gas supplier to make
sure sufficient gas pressure is available to operate
the primary regulator.
• Gas pressure at the inlet to the fuel shutoff sole-
noid should not exceed approximately 14 inches
water column (0.5 psi). Optimum pressure at the
fuel shutoff solenoid is 11 inches water column
(0.4 psi).
PROPANE VAPOR WITHDRAWAL FUEL SYSTEM
This type of system utilizes the vapors formed above
the liquid fuel in the supply tank. Approximately 10
to 20 percent of the tank capacity is needed for fuel
expansion from the liquid to the vapor state. The
vapor withdrawal system is generally best suited for
smaller engines that require less fuel. The installer
should be aware of the following:
• The natural gas and LP gas systems are similar.
However, the natural gas system delivers gas at a
pressure of approximately five inches water col-
umn to the carburetor.
• When ambient temperatures are low and engine
fuel consumption is high, the vapor withdrawal
system may not function efficiently.
• Ambient temperatures around the supply tank
must be high enough to sustain adequate vaporiza-
tion, or the system will not deliver the needed fuel
volume.
• In addition to the cooling effects of ambient air, the
vaporization process itself provides an additional
cooling effect.
LP FUEL SYSTEM
LP is supplied as a liquid in pressure tanks. It is
usually made up of propane, butane, or a mixture of
the two gases. Propane tends to vaporize readily even
at temperatures as low as -20° F (-29° C). However,
butane reverts to its liquid state when temperatures
drop below 32° F (0° C).
LP in a liquid withdrawal system must be converted
to its gaseous state before it is introduced into the
engine carburetor. A vaporizer-converter is generally
used to accomplish this. In such a converter, heated
engine coolant is ported through the converter to
provide the necessary heat for conversion of the fuel
from a liquid to a gaseous state.

GENERATOR AC LEAD CONNECTIONS
See “Voltage Codes”. This generator may be rated
at any one of three voltages, either single-phase or
three-phase. The electrical wires in the unit’s AC con-
nection (lower) panel should be installed according to
the number of leads and the voltage/phase required
for the application. If there are any questions regard-
ing lead connection, refer to the wiring diagrams at
the back of this manual.
Voltage codes apply to the type of stator assembly
installed on a particular generator.
FOUR-LEAD, SINGLE-PHASE STATOR
Four-lead generators (see Figure 7.1) are designed to
supply electrical loads with voltage code “A” (240V,
1-phase, 60 Hz). Electrical power is produced in the
stator power windings. These windings were con-
nected at the factory to the main circuit breaker as
shown in Figure 7.1.
The rated voltage between each circuit breaker ter-
minal is 240V. The rated voltage between each circuit
breaker terminal and the neutral point 00 is 120V.
Figure 7.1 — Four-lead, Single-phase Stator
ALTERNATOR POWER WINDING
CONNECTIONS
3-PHASE ALTERNATORS
The generator is designed to supply 3-phase electri-
cal loads. Electric power is produced in the alterna-
tor power windings. These windings were connected
at the factory to the main circuit breaker with a “Y”
configuration as shown in Figures 7.2 and 7.3.
The rated voltage between circuit breaker terminals
E1-E2, E1-E3 and E2-E3 is either 480V or 208V
depending on the model.
The rated voltage between each circuit breaker termi-
nal and the neutral point 00 is either 277V or 120V
depending on the model.

![](asset-d.png)
INSTALLATION
Refer to the separate “Installation Guide QT Product
Line” supplied with the unit.
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”, as well as all other
safety information in this manual, before attempting
to operate this (and related) equipment.
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
and the “Service Schedule”.
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.
FUEL SYSTEM
Make sure the fuel supply system to the genera-
tor (a) delivers the correct fuel at the correct pres-
sure and (b) is properly purged and leak tested
according to code. No fuel leakage is permitted. See
“Specifications” for more information.
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 “break-in” oil. This oil should be changed
after 30 hours of operation.
Check the oil level in the generator gearbox (if so
equipped) prior to initial use and at the intervals
indicated by the “Service Schedule.” The recom-
mended oil is SAE 90 gear lubricant.
Also, if the engine is equipped with a mechanical gov-
ernor, make sure the governor is properly lubricated
with clean engine oil.
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.
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” sections.
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).
ELECTRICAL SYSTEM
Make sure the generator is properly connected to an
approved earth ground.
Make sure the generator battery is fully charged,
properly installed and interconnected, and ready for
use.
Check to ensure that there are no loose electrical con-
nections. Restrain any loose wires to keep them clear
of any moving generator set components.
INITIAL INSPECTION FOR QT GENSET

EVERY 800 OPERATING HOURS
1. Retorque cylinder head.
2. Retorque intake and exhaust manifold.
3. Check engine compression.
4. Check valve clearance.
COOLING SYSTEM
Air intake and outlet openings in the generator com-
partment must be open and unobstructed for contin-
ued proper operation. This includes such obstruc-
tions as high grass, weeds, brush, leaves and snow.
Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it
to shut down. (See the installation diagram.)
The exhaust system parts from this product get
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc. must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
OVERLOAD PROTECTION FOR ENGINE
DC ELECTRICAL SYSTEM
Engine cranking, start up and running are controlled
by a solid state Engine Controller circuit board.
Battery voltage is delivered to that circuit board via
a 15 amp fuse. These overcurrent protection devices
will open if the circuit is overloaded.
If a circuit breaker opens or a fuse element
melts, find the cause of the overload before
resetting the circuit breaker or replacing the
fuse.
CHECKING FLUID LEVELS
CHECK ENGINE OIL
Check engine crankcase oil level (Figure 10.1) at least
every 20 hours of operation, or prior to use.
• Remove oil dipstick and wipe dry with a clean, lint-
free cloth.
• Install oil dipstick, then remove again.
• Oil should be between FULL and ADD marks.
• If oil level is below the dipstick ADD mark, remove
oil fill cap-. Add the recommended oil to bring oil
level up to the FULL mark. DO NOT FILL ABOVE
THE “FULL” MARK. See “Engine Oil Recommen-
dations” for recommended oils.

Complete a thorough visual inspection of the entire
engine-generator monthly. Look for obvious damage,
loose, missing or corroded nuts, bolts and other fas-
teners. Look for fuel, oil or coolant leaks.
INSPECT EXHAUST SYSTEM
Inspect the exhaust system at least once every three
months. Check all exhaust system pipes, mufflers,
clamps, etc. for condition, tightness, leaks, security,
damage.
CHECK FAN BELT
• Inspect fan belts every three months. Replace any
damaged, deteriorated, worn or otherwise defec-
tive belt.
• Check fan belt tension. Thumb pressure, exerted
midway between pulleys, should deflect about 3/8
to 5/8 of an inch. Adjust belt tension as required.
INSPECT ENGINE GOVERNOR
Visually inspect electronic governor.
DANGER
Do not attempt to adjust the governor. Only
qualified service facilities should adjust the
governor. Excessively high operating speeds
are dangerous and increase the risk of personal
injury. Low speeds impose a heavy load on the
engine when adequate engine power is not
available and may shorten engine life. Correct
rated frequency and voltage are supplied only
at the proper governed speed. Some connected
electrical load devices may be damaged by incor-
rect frequency and/or voltage. Only qualified
service technicians should adjust the governed

MISCELLANEOUS MAINTENANCE
CLEANING THE GENERATOR
Keep the generator as clean and as dry as possible.
Dirt and moisture that accumulates on internal gen-
erator windings have an adverse effect on insulation
resistance.
Periodically clean generator exterior surfaces. A soft
brush may be used to loosen caked on dirt. Use a
vacuum system or dry, low pressure air to remove
any accumulations of dirt. The generator is housed
inside an all-weather enclosure, clean the enclosure
with a soft, damp cloth or sponge and water.
Once each year have the generator cleaned and
inspected by an Authorized Service Dealer. That
dealer will use dry, low pressure air to clean internal
windings. Parts inside the control console should be
cleaned and inspected at this time as well.
Finally, have the insulation resistance of stator and
rotor windings checked. If insulation resistances are
excessively low, the generator may require drying.
BATTERY
All lead-acid storage batteries discharge when not in
use. Refer to specific instructions and warnings that
accompany the battery. If such information is not
available, observe the following precautions when
handling a battery:
• DO NOT use jumper cables and a booster battery
to crank or start the generator engine.
• DO NOT recharge a weak battery while it is
installed in the generator. Remove battery from
generator and recharge in a well-ventilated area,
away from fuel vapors, sparks, heat or flames.
• Battery electrolyte fluid is an extremely caustic
sulfuric solution that can cause severe burns. DO
NOT permit fluid to contact eyes, skin, clothing,
painted surfaces, wiring insulation, etc. If any bat-
tery fluid is spilled, flush the affected area with
clear water immediately.
• Always wear safety glasses, rubber apron and
gloves when handling a battery.
• Batteries give off explosive hydrogen gas while
charging. The gas can form an explosive mixture
around the battery for several hours after charging.
Any spark, heat or flames can ignite the gas and
cause an explosion which can shatter the battery,
causing blindness or other serious injury.
BATTERY MAINTENANCE
The battery should be inspected per Section 4.7,
Scheduled Maintenance. The following procedure
should be followed for inspection:
1. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
2. Check the battery fluid level of unsealed batteries
and, if necessary, fill with DISTILLED WATER
ONLY. DO NOT USE TAP WATER IN BATTERIES.
3. Have the state of charge and condition checked.
This should be done with an automotive-type bat-
tery hydrometer.
DANGER
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Battery electrolyte fluid is an extremely corro-
sive sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
Do not use any jumper cables or booster battery
to crank and start the generator engine. If the
battery has completely discharged, remove it
from the generator for recharging.
Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position, before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as the
battery cables are connected.
Be sure the 120VAC power supply to the battery
is turned OFF, or sparking may occur at the bat-
tery posts as the cables are attached and cause
an explosion.
BATTERY REPLACEMENT
When replacing batteries, use the same number and
the type of battery that follows:
NOTE:
The BCI number should be located directly on the
battery.

SERVICE SCHEDULE
The following is a recommended maintenance schedule for small standby and residential generator sets. The
established intervals in the schedule are the maximum recommended when the unit is used in an average service
application. They will need to be decreased (performed more frequently) if the unit is used in a severe applica-
tion. Use calendar time or accumulated run time, from the previous maintenance interval to determine the next
required maintenance interval.
Service Maintenance Interval Information:
The various service maintenance intervals are designated by interval numbers as follows:
1 An early inspection of the generator set to insure it is ready to operate when required and to identify any poten-
tial problem areas.
Performed monthly this requires approximately .5 man-hours per unit to complete.
This inspection may be performed by the end user providing the following safety steps are taken to prevent
the engine from starting automatically without warning:
To prevent injury, perform the following steps in the order indicated before starting any maintenance:
• Disable the generator set from starting and/or connecting to the load by setting the control panel
AUTO/OFF/MANUAL switch to the OFF position.
• Remove the 5 amp and 15 amp control panel fuses.
• Turn off the battery charger (turn OFF utility supply to ATS).
• Remove the negative battery cable.
The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condition
from burning out sensitive control panel components and circuits.
Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal
operation when required.
2 A break-in service inspection of the generator set to insure it is ready to operate and carry the load when
required, and to identify any potential problem areas.
Performed ONLY ONCE following the first three months, or 30 run time hours of operation after purchase of
the unit and requires approximately 2.5 man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by a Service Dealer.
3 An operational inspection of the generator set to insure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed semi-annually this requires approximately 1.5 man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by a Service Dealer.
4 A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required,
and to identify any potential problem areas.
Performed annually this requires approximately 4.0 man-hours per unit to complete.
This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge
to accomplish and should be performed only by a Service Dealer.
