Please read all hazards carefully!



2

GENERAL HAZARDS



• For safety reasons, the manufacturer recommends

that the installation, initial start-up and main­tenance of this equipment is carried out by an
Authorized Dealer.

• The engine exhaust fumes contain carbon monox-

ide, which can be DEADLY. This dangerous gas, if
breathed in sufficient concentrations, can cause
unconsciousness or even death. This exhaust
system must be installed properly, in strict com­pliance with applicable codes and standards.
Following installation, do nothing that might ren­der the system unsafe or in noncompliance with
such codes and standards.

• 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 to correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seri­ously affect safe operation of the generator. The
generator MUST be installed outdoors.

• 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 contact the

nearest Authorized Dealer for parts needing repair
or replacement.

• 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 con­ditions 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 does the standby generator when it is in opera­tion. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure
all appropriate covers, guards and barriers are in





Air-cooled 7 kW, 12 kW and 15 kW Generators

place before operating the generator. 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.

• The National Electrical Code (NEC) requires the
frame and external electrically conductive parts of
the generator to be connected to an approved earth
ground. Local electrical codes also may require
proper grounding of the generator electrical sys­tem.

• After installing this home standby electrical sys­tem, the generator may crank and start at any
time without warning. When this occurs, load cir­cuits are transferred to the STANDBY (generator)
power source. To prevent possible injury if such a
start and transfer occur, always set the generator’s
AUTO/OFF/MANUAL switch to its OFF position
before working on equipment and remove the 5A
and 15A fuses from the generator control panel.

• In case of accident caused by electric shock, imme­diately 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 implement,
such as a rope or board, to free the victim from the
live conductor. If the victim is unconscious, apply
first aid and get immediate medical help.

• Never wear jewelry when working on this equip­ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com­ponents causing injury.

FIRE HAZARDS



• For fire safety, the generator must be installed
and maintained properly. Installation always must
comply with applicable codes, standards, laws
and regulations. Adhere strictly to local, state and
national electrical and building codes. Comply
with regulations the Occupational Safety and
Health Administration (OSHA) has established.
Also, ensure that the generator is installed in
accordance with the manufacturer’s instructions
and recommendations. Following proper installa­tion, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regula­tions.

• Keep a fire extinguisher near the generator at all
times. Extinguishers rated “ABC” by the National
Fire Protection Association are appropriate for
use on the standby electric system. Keep the extin­guisher properly charged and be familiar with its
use. If there are any questions pertaining to fire
extinguishers, consult the local fire department.



IMPORTANT SAFETY INSTRUCTIONS

EXPLOSION HAZARDS



• Do not smoke around the generator. Wipe up any
fuel or oil spills immediately. Ensure that no com­bustible materials are left in the generator com­partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround­ing the generator clean and free from debris.

• Gaseous fluids such as natural gas and liquid pro­pane (LP) gas are extremely EXPLOSIVE. Install
the fuel supply system according to applicable
fuel-gas codes. Before placing the home standby
electric system into service, fuel system lines must
be properly purged and leak tested according to
applicable code. After installation, inspect the fuel
system periodically for leaks. No leakage is permit­ted.

DANGER

Only qualified electricians or contractors should



attempt such installations, which must comply
strictly with applicable codes, standards and
regulations.

1.1 UNPACKING/INSPECTION

After unpacking, carefully inspect the contents
for damage.

• This standby generator set has been factory sup­plied with a weather protective enclosure that is
intended for outdoor installation only.

If this generator is used to power electrical load



circuits normally powered by a utility power
source, it is required by code to install a trans­fer switch. The transfer switch must effectively
isolate the electrical system from the utility
distribution system when the generator is oper­ating (NEC 700, 701 and 702). Failure to isolate
an electrical system by such means will result in
damage to the generator and also may result in
injury or death to utility power workers due to
backfeed of electrical energy.

If any loss or damage is noted at time of delivery, have
the person(s) making the delivery note all damage on
the freight bill or affix his or her signature under the
consignor's memo of loss or damage.

If there is loss or damage after delivery, separate the
damaged materials and contact the carrier for claim
procedures.

“Concealed damage” is understood to mean damage
to the contents of a package that is not in evidence at
the time of delivery, but is discovered later.

1.2 PROTECTION SYSTEMS

Unlike an automobile engine, the generator may have
to run for long periods of time with no operator pres­ent to monitor engine conditions. For that reason, the
engine is equipped with the following systems that
protect it against potentially damaging conditions:

1. Low Oil Pressure Sensor 3. Overcrank

2. High Temperature Sensor 4. Overspeed
There are LED readouts on the control panel to notify

personnel that one of these faults has occurred. There
is also a “System Set” LED that is described below.

1.3 SYSTEM SET LED

The “System Set” LED is lit when all of the following
conditions are true:

1. The AUTO/OFF/MANUAL switch is set to the
AUTO position.

2. The utility voltage being supplied to the unit is
being sensed by the Control PCB. If the utility
sense voltage is not connected to the unit or if it
is below 168 volts AC, then the system set light
will flash rapidly. This indicates that if the AUTO/
OFF/MANUAL switch is placed in the Auto posi­tion , the generator will start.

3. The “Not In Auto” dip switch is set to the OFF
position on the control board.

4. No alarms are present, for example, low oil pres­sure, high temperature, etc.

1.6 FUEL REQUIREMENTS

AND RECOMMENDATIONS

With LP gas, use only the vapor withdrawal
system. This type of system uses the vapors formed

above the liquid fuel in the storage tank.

The engine has been fitted with a fuel carburetion
system that meets the specifications of the 1997
California Air Resources Board for tamper-proof
dual fuel systems. The unit will run on natural gas or
LP gas, but it has been factory set to run on natural
gas. Should the primary fuel need to be changed to
LP gas, the fuel system needs to be reconfigured. See
Section 1.9 for instructions on reconfiguration of the
fuel system.

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

7 inches water colum (0.18 to 0.25 psi); and for
liquid propane, 10 inches to 12 inches of water
column (0.36 to 0.43 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 4 inches
water colum for natural gas or 10 inches water
column for liquid propane for all load ranges.

1.9 LOCATION

1.9.1 GENERATOR



Install the generator set, in its protective enclosure,
outdoors, where adequate cooling and ventilating air
is always available. Consider these factors:

• Install the unit where air inlet and outlet open-

ings will not become obstructed by leaves, grass,
snow, etc. If prevailing winds will cause blowing or
drifting, consider using a windbreak to protect the
unit.

• Install the generator on high ground where water

levels will not rise and endanger it.

• Allow sufficient room on all sides of the generator

for maintenance and servicing. A good rule is to
allow three feet of space on all sides.

• Where strong prevailing winds blow from one

direction, face the generator air inlet openings to
the prevailing winds.

• Install the generator as close as possible to the fuel

supply, to reduce the length of piping.

• Install the generator as close as possible to

the transfer switch. HOWEVER, REMEMBER
THAT LAWS OR CODES MAY REGULATE THE
DISTANCE.

1.9.2 TRANSFER SWITCH

Transfer switches for use with these generators
are sold separately and can be purchased from
Authorized Dealers.

• Install the transfer switch on a firm, sturdy sup-

porting structure.

• To prevent switch distortion, level the switch if

necessary. This can be done by placing washers
between the switch enclosure and mounting sur­face.

• Never install the switch where water or any corro-

sive substance might drip onto the enclosure.

• Protect the switch at all times against excessive

moisture, dust, dirt, lint, construction grit and cor­rosive vapors.

• Failure to utilize the manufacturer’s transfer switch

with this generator may void the warranty.

Section 1 — General Information

1.10 BATTERY INSTALLATION

Fill the battery with the proper electrolyte fluid if
necessary and have the battery fully charged before
installing it.

Before installing and connecting the battery, complete
the following steps:

1. Set the generator's AUTO/OFF/MANUAL switch to
OFF.

2. Turn off utility power supply to the transfer
switch.

3. Remove the 5 amp fuse from the generator con­trol panel.

If the AUTO/OFF/MANUAL switch is not set to its



OFF position, the generator can crank and start
as soon as the battery cables are connected. If
the utility power supply is not turned off, spark­ing can occur at the battery posts and cause an
explosion.

Battery cables were factory connected at the genera­tor (Figure 1.5). Connect cables to battery posts as
follows:

4. Connect the red battery cable (from starter con­tactor) to the battery post indicated by a positive,
POS or (+).

5. Connect the black battery cable (from frame
ground) to the battery post indicated by a nega­tive, NEG or (—).

6. Replace the 5 amp fuse in the generator control
panel.

NOTE:

Damage will result if battery connections are made
in reverse.

Figure 1.5 – Battery Cable Connections

NOTE:

The generator is equipped with 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 while the engine is not running, to prevent
self-discharge. The trickle charger is designed to
help extend the life of the battery by maintain­ing the battery when the unit is not running. The
trickle charge feature cannot be used to recharge
a discharged battery.

1.11 THE BATTERY

Servicing of the battery is to be performed or super­vised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized person­nel away from batteries.

When replacing the battery, use the following type of
battery: Group 26/26R 12-volt battery with a rating
of 350 cold-cranking amps minimum for 7 kW; 525
cold-cranking amps minimum for 12 and 15 kW at

-18º C (0º F) minimum. When using a maintenance­free battery, it is not necessary to check the specific
gravity or electrolyte level. 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 diagrams. Make
sure the battery is correctly connected and terminals
are tight. Observe battery polarity when connecting
the battery to the generator set.

DANGER

Do not dispose of the battery in a fire. The



battery is capable of exploding.

A battery presents a risk of electrical shock



and high short circuit current. The following pre­cautions are to be observed when working on
batteries:

• Remove watches, rings or other metal objects;

• Use tools with insulated handles;

• Wear rubber gloves and boots;

• Do not lay tools or metal parts on top of the
battery; and

• Disconnect charging source prior to connecting or
disconnecting battery terminals.

Do not open or mutilate the battery. Released



electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.

The electrolyte is a dilute sulfuric acid that is



harmful to the skin and eyes. It is electrically
conductive and corrosive.

9

Section 2 — Post Installation Start-up and Adjustments

Air-cooled 7 kW, 12 kW and 15 kW Generators

The following procedures are to be observed:

• Wear full eye protection and protective clothing;

• Where electrolyte contacts the skin, wash it off
immediately with water;

• Where electrolyte contacts the eyes, immediately
flush thoroughly with water and seek medical
attention; and

• Spilled electrolyte is to be washed down with an
acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or 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 procedures are to be followed:

• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark in battery area; and

• Discharge static electricity from body before touch­ing the battery by first touching a grounded metal
surface.

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 utility power supply is turned off, or



sparking may occur at the battery posts as the
cables are attached and cause an explosion.

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. Check the engine crankcase oil level and, if neces-

sary, fill to the dipstick FULL mark with the rec­ommended oil. Do not fill above the FULL mark.

5. 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.

2.2 CHECK TRANSFER SWITCH
OPERATION

Refer to Section 3.5 of the owner’s manual for manu­al operation procedures.

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. Turn on the utility power supply to the transfer

switch using the means provided (such as a utility
main line circuit breaker).

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.

2. Use an accurate AC voltmeter to check utility

power source voltage across terminals N1 and
N2. Nominal line-to-line voltage should be 240
volts AC.

3. Check utility power source voltage across termi-

nals N1 and the transfer switch neutral lug; then
across terminal N2 and neutral. Nominal line-to­neutral voltage should be 120 volts AC.

4. When certain that utility supply voltage is compat-

ible with transfer switch and load circuit ratings,
turn OFF the utility power supply to the transfer
switch.

5. Set the generator's main circuit breaker to its

OFF (or open) position. Initial tests will be con­ducted at no-load condition.

6. On the generator panel, set the AUTO/OFF/

MANUAL switch to MANUAL. The engine should
crank and start.

7. Let the engine warm up for about five minutes to

allow internal temperatures to stabilize. Then, set
the generator’s main circuit breaker to its ON (or
closed) position.

DANGER

Never operate the engine with the oil level



below the “Add” mark on the dipstick. Doing
this could damage the engine.

10

8. Connect an accurate AC voltmeter and a fre­quency meter across transfer switch terminal
lugs E1 and E2. Voltage should be 242-252 volts;
frequency should read about 61-63 Hertz.

9. Connect the AC voltmeter test leads across ter­minal lug E1 and neutral; then across E2 and
neutral. In both cases, voltage reading should be
121-126 volts AC.

10. Set the generator’s main circuit breaker to its
OFF (or open) position. Let the engine run at no­load for a few minutes to stabilize internal engine
generator temperatures.

11. Set the generator's AUTO/OFF/MANUAL switch to
OFF. The engine should shut down.

NOTE:

It is important not to proceed until certain that
generator AC voltage and frequency are correct
and within the stated limits. Generally, if both AC
frequency and voltage are high or low, the engine
governor requires adjustment. If frequency is cor­rect, but voltage is high or low, the generator’s
voltage regulator requires adjustment.

2.4 GENERATOR TESTS UNDER LOAD

To test the generator set with electrical loads applied,
proceed as follows:

1. Set generator’s main circuit breaker to its OFF
(or open) position.

2. Set the generato r's AU TO/OFF/ MANUAL
switch to OFF.

3. Turn OFF the utility power supply to the transfer
switch, using the means provided (such as a util­ity main line circuit breaker).

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.

4. Manually set the transfer switch to the STANDBY
position, i.e., load terminals connected to the
generator's E1/E2 terminals. The transfer switch
operating lever should be down.

5. Set the generator's AUTO/OFF/MANUAL switch
to MANUAL. The engine should crank and start
immediately.

6. Let the engine stabilize and warm up for a few
minutes.

7. Set the generator’s main circuit breaker to its ON

the standby generator.

8. Turn ON electrical loads. Apply an electrical load
equal to the full rated wattage/amperage capacity
of the installed generator.

9. Connect an accurate AC voltmeter and a frequen­cy meter across terminal lugs E1 and E2. Voltage
should be greater than 230 volts; frequency
should be greater than 58 Hertz.

10. Let the generator run at full rated load for 20-30
minutes. Listen for unusual noises, vibration or
other indications of abnormal operation. Check
for oil leaks, evidence of overheating, etc.

11. When testing under load is complete, turn OFF
electrical loads.

12. Set the generator's main circuit breakers to their
OFF (or open) positions.

13. Let the engine run at no-load for a few minutes.

14. Set the AUTO/OFF/MANUAL switch to OFF. The

position, i.e., load terminals connected to the util­ity power source side.

4. Turn ON the utility power supply to the transfer
switch, using the means provided (such as a util­ity main line circuit breaker).

5. Set the AUTO/OFF/MANUAL switch to AUTO.
Then set the generator’s main circuit breaker to
its ON (or closed) position. The system is now
ready for automatic operation.

6. Turn OFF the utility power supply to the transfer
switch.

With the AUTO/OFF/MANUAL switch at AUTO, the
engine should crank and start when the utility source
power is turned OFF. After starting, the transfer
switch should connect load circuits to the standby
side. Let the system go through its entire automatic
sequence of operation.

With the generator running and loads powered by
generator AC output, turn ON the utility power supply
to the transfer switch. The following should occur:

• After about 15 seconds, the switch should transfer

loads back to the utility power source.

• About one minute after retransfer, the engine

should shut down.

Air-cooled 7 kW, 12 kW and 15 kW Generators

2.6 ADJUSTING THE REGULATOR
(NATURAL GAS ONLY)

Although the generator has been factory set to pro­vide maximum power, it may be necessary in some
areas to adjust this setting. Because natural gas has
different BTU or power content across the country
the engine may not perform as designed.

If experiencing engine problems at high or full load
conditions follow these steps. It will require a fre­quency meter to perform this procedure.

1. Turn off utility power to the main distribution

panel in the house. This can be done by switching
the service main breaker to the off or open posi­tion.

2. Allow the generator to start before loading the

generator. Confirm the no-load frequency with
the roof open and door off is set at 63-63.5 Hz.
Transfer load to emergency circuits.

3. Turn on appliances, lights, pumps, etc., that are

on the emergency circuits in an attempt to fully
load the generator. Be cautious not to overload
the generator. Use the following chart as a guide:

Unit 120 Volts 240 Volts

7 kW 50.0 amps 25.0 amps
12 kW 83.3 amps 41.6 amps
15 kW 108.3 amps 54.1 amps

4. When 3/4 load has been achieved. Connect a fre-

quency meter to the output lugs of the generator’s
main line circuit breaker.

5. The fuel regulator is fitted with one (7 kW), or two

(12 & 15 kW) adjustment screws. While watching
the frequency meter, slowly turn the adjustment
screw clockwise or counterclockwise one at a
time until highest frequency is read on the meter.
Only limited adjustment is available between the
set pins. Under no circumstances should any of
the pins be removed (Figures 2.1 and 2.2).

7. Turn utility power to the main distribution panel
back on. This can be done by switching the ser­vice main breaker to the on or closed position.
Allow the generator to shut down.

Do not make any unnecessary adjustments.



Factory settings are correct for most applica­tions. However, when making adjustments, be
careful to avoid overspeeding the engine.

If this procedure or equipment are not available,
locate the nearest Authorized Dealer and they can
perform the adjustments.

NOTE:

A service fee may be charged for this adjustment.

direct proportion to frequency. For example, at 62
Hertz, line-to-neutral voltage will be 124 volts.

3.1 BREAK-IN PROCEDURE

Once the unit has been installed, with utility power
connected to the transfer switch, and all electrical
checks have been made, it is strongly recommended
that the following “Break-in Procedure” be completed
to ensure correct generator operation in the future.

1. Set the generator’s AUTO/OFF/MANUAL switch to
AUTO.

2. Turn OFF the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).

3. The unit will start, and the transfer switch will
transfer to standby.

4. Run the unit for one hour at 25 percent load.

5. Run the unit for one hour at 50 percent load.

6. Run the unit for one hour at 75 percent load.

7. Run the unit for one hour at 100 percent load.

8. Turn ON the utility power supply to the transfer
switch, which will allow the transfer switch to
transfer back to utility power. The unit will con­tinue to run for one minute and then shut down.

9. Allow the unit to cool.

10. Drain the oil and remove the oil filter. Replace
the oil filter according to Section 4.4, “Changing
the Oil Filter”. Replace the oil with synthetic oil
as recommended in Section 4.3, “Changing the

3.3 AUTOMATIC TRANSFER
OPERATION

To select automatic operation, do the following:

1. Make sure the transfer switch main contacts are

set to their “Utility” position, i.e., loads connected
to the utility power source (Figure 3.2).

2. Be sure that normal utility power source voltage

is available to transfer switch terminal lugs N1
and N2.

3. Set the generator’s AUTO/OFF/MANUAL switch to

AUTO.

4. Set the generator’s main circuit breaker to its ON

(or closed) position.

With the preceding steps complete, the generator will
start automatically when utility source voltage drops
below a preset level. After the unit starts, loads are
transferred to the standby power source. Refer to
Section 3.4, “Sequence of Automatic Operation.”

3.4 SEQUENCE OF AUTOMATIC
OPERATION

The generator’s control panel houses a control logic
circuit board. This board constantly monitors util­ity power source voltage. Should that voltage drop
below a preset level, circuit board action will signal
the engine to crank and start. After the engine starts,
the circuit board signals the transfer switch to acti­vate and connect load circuits to the standby power
supply (load terminal lugs T1/T2 connect to terminal
lugs E1/E2).

Section 3 — Operation

Air-cooled 7 kW, 12 kW and 15 kW Generators

Upon restoration of utility source voltage above a
preset level, generator circuit board action signals the
transfer switch to transfer loads back to that power
supply. After retransfer, the engine is signalled to shut
down.

The actual sequence of operation is controlled by
sensors and timers on a control logic circuit board,
as follows:

A. Utility Voltage Dropout Sensor

• This sensor monitors utility source voltage.

• If utility source voltage drops below about 60
percent of the nominal supply voltage, the sensor
energizes a 15-second timer.

• Once the timer has expired, the engine will crank
and start.

B. Engine Warm-up Time Delay

• This mechanism lets the engine warm up for
about 10 seconds before the load is transferred
to a standby source.

C. Standby Voltage Sensor

• This sensor monitors generator AC output volt­age. When the voltage has reached 50 percent of
the nominal rated voltage, transfer to standby
can occur.

D. Utility Voltage Pickup Sensor

• This sensor monitors utility power supply volt­age. When that voltage is restored to above 70
percent of the nominal source voltage, a retrans­fer time delay starts timing.

E. Retransfer Time Delay

• This timer runs for about 15 seconds.

• At end of a 15-second delay, circuit board action
de-energizes the transfer relay in the transfer
switch.

• Retransfer to utility power source then occurs.

F. Engine Cool-down Timer

• When the load is transferred back to utility power
source, the engine cool-down timer starts tim­ing.

• The timer will run for about one minute, and the
generator will then shut down.

3.5 MANUAL TRANSFER OPERATION

once every seven days, on the day of the week and at
the time of day the following sequence is completed.
During this exercise period, the unit runs for approx­imately 12 minutes and then shuts down. Transfer of
loads to the generator output does not occur during
the exercise cycle.

A switch on the control panel (see Figure 3.1) allows
for selection of the day and time for system exercise.
To select the desired day and time of day, the follow­ing sequence must be done at that time.

1. Verify that the AUTO/OFF/MANUAL switch is set
to AUTO.

2. Hold down the set timer switch until the genera­tor starts (approximately 10 seconds) and then
release.

3. The generator will start and run for approximately
12 minutes and then shut down on its own. The
exerciser will then be set to run at that time of day
every week.

NOTE:

The exerciser will only work in the AUTO mode
and will not work unless this procedure is per­formed. The exerciser will need to be reset every
time the 12-volt battery is disconnected and then
reconnected. The exerciser WILL NOT work if
dip switch 2 (Remote Not Auto) on the controller
printed circuit board is ON.

3.7 PROTECTION SYSTEMS

3.7.1 LOW OIL PRESSURE SWITCH



This switch (Figure 3.3) 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.

3.7.2 HIGH TEMPERATURE SWITCH



This switch’s contacts (Figure 3.3) close if the tem­perature should exceed approximately 140º C (284º
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.

3.7.3 OVERCRANK



This feature prevents the generator from damaging
itself when it continually attempts to start and anoth­er problem, such as no fuel supply, prevents it from
starting. The unit will crank and rest for a preset time
limit. Then, it will stop cranking, and the LED will
light indicating an overcrank failure. The AUTO/OFF/
MANUAL switch will need to be set to OFF and then
back to AUTO to reset the generator control board.

NOTE:

If the fault is not repaired, the overcrank feature
will continue to activate.

3.7.4 OVERSPEED



This feature protects the generator from damage by
shutting it down if it happens to run faster than the
preset limit. This protection also prevents the gen­erator from supplying an output that could poten­tially damage appliances connected to the generator
circuit. Contact the nearest Authorized Dealer if this
failure occurs.

4.1 FUSE

The generator panel’s 15 amp fuse (Figure 4.1) pro­tects the DC control circuit against overload. The fuse
is wired in series with the battery output lead to the
panel. If the fuse element has melted open, the engine
cannot crank or start. Replace the fuse using only an
identical 15-amp replacement.

The generator panel’s 5 amp fuse protects the battery
charge circuit against overload. If the fuse element has
melted open, battery charging will not be possible.
Replace the fuse using only an identical 5 amp replace­ment. To remove fuse, push cap down and rotate coun­terclockwise.

2. Remove the dipstick and wipe it dry with a
clean cloth.

3. Install the dipstick; then, remove it again. The oil
level should be at the dipstick “Full” mark. If nec­essary, add oil to the “Full” mark only. DO NOT
FILL ABOVE THE “FULL” MARK.

Never operate the engine with the oil level



below the “Add” mark on the dipstick. Doing
this could damage the engine.

4. Install the dipstick.

5. Reset the AUTO/OFF/MANUAL switch to its origi­nal position.

4.6 SPARK PLUG(S)

Reset the spark plug(s) gap or replace the spark
plug(s) as necessary. See Section 4.13 for mainte­nance requirements.

1. Clean the area around the base of the spark
plug(s) to keep dirt and debris out of the engine.
Clean by scraping or washing using a wire brush
and commercial solvent. Do not blast the spark
plug(s) to clean.

2. Remove the spark plug(s) and check the condi­tion. Replace the spark plug(s) if worn or if reuse
is questionable. See Section 4.13 for recommend­ed inspection.

3. Check the spark plug gap using a wire feeler
gauge. Adjust the gap to 0.76 mm (0.030 inch)
for 7 kW and 0.50 mm (0.020 inch) for 12/15 kW
by carefully bending the ground electrode (Figure

4.8).

4.7 BATTERY MAINTENANCE

The battery should be inspected per the “Service
Schedule,” Section 4.13. 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 bat­tery hydrometer.

DANGER

Do not dispose of the battery in a fire. The



battery is capable of exploding.

A battery presents a risk of electrical shock



and high short circuit current. The following pre­cautions are to be observed when working on
batteries:

• Remove watches, rings or other metal objects;

• Use tools with insulated handles;

• Wear rubber gloves and boots;

• Do not lay tools or metal parts on top of the

battery; and

• Disconnect charging source prior to connecting or

disconnecting battery terminals.

Do not open or mutilate the battery. Released



electrolyte has been known to be harmful to the
skin and eyes, and to be toxic.

The electrolyte is a dilute sulfuric acid that is



harmful to the skin and eyes. It is electrically
conductive and corrosive. The following
procedures are to be observed:

• Wear full eye protection and protective clothing;

• Where electrolyte contacts the skin, wash it off

immediately with water;

• Where electrolyte contacts the eyes, immediately

flush thoroughly with water and seek medical
attention; and

• Spilled electrolyte is to be washed down with an

acid neutralizing agent. A common practice is to
use a solution of 1 pound (500 grams) bicarbonate
of soda to 1 gallon (4 liters) or 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

19

Section 4 — Maintenance

Air-cooled 7 kW, 12 kW and 15 kW Generators

following procedures are to be followed:

• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark in battery area; and

• Discharge static electricity from body before touch­ing the battery by first touching a grounded metal
surface.

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 utility power supply is turned off, and



the 5A fuse is removed from the generator control
panel, or sparking may occur at the battery posts
as the cables are attached, causing an explosion.

4.8 ADJUSTING VALVE CLEARANCE

After the first six months of operation, adjust the
valve clearance in the engine.

Important: If feeling uncomfortable about doing this

procedure or the proper tools are not available, contact
the nearest Authorized Dealer for service assistance.
This is a very important step to insure longest life for
the engine.

To adjust valve clearance:

• Make sure the engine is at room temperature.

• Make sure that the spark plug wire is removed from

the spark plug and out of the way.

• Remove the four screws attaching the valve cover with

a #2 or #3 phillips screwdriver.

• Make sure the piston is at Top Dead Center (TDC) of

its compression stroke (both valves closed). To get
the piston at TDC, remove the intake screen at the
front of the engine to gain access to the flywheel nut.
Use a large socket and socket wrench to rotate the
nut and hence the engine. While watching the piston
through the spark plug hole. The piston should move
up and down. The piston is at TDC when it is up as
high as it can go.

• Loosen the rocker jam nut. Use an 10mm allen

wrench to turn the pivot ball stud while checking
clearance between the rocker arm and the valve stem
with a feeler gauge. Correct clearance is 0.002-0.004
inch (0.05-0.1 mm).

NOTE:

Hold the rocker arm jam nut in place as the pivot
ball stud is turned.

When valve clearance is correct, hold the pivot ball stud
in place with the allen wrench and tighten the rocker
arm jam nut. Tighten the jam nut to 174 in/lbs. torque.
After tightening the jam nut, recheck valve clearance to
make sure it did not change.

Rocker

Pivot Ball

Stud

Jam Nut

• Install new valve cover gasket.

• Re-attach the valve cover.

NOTE:

Start all four screws before tightening or it will not
be possible to get all the screws in place. Make sure
the valve cover gasket is in place.

• Re-attach the spark plug wire to the spark plug.

• Repeat the process for the other cylinder.

4.9 COOLING SYSTEM

Air inlet and outlet openings in the generator compart­ment must be open and unobstructed for continued
proper operation. This includes such obstructions as
high grass, weeds, brush, leaves and snow.

Without sufficient cooling and ventilating air flow, the
engine/generator quickly overheats, which causes it to
quickly shut down. (See Figure 4.9 for vent locations.)

Figure 4.9 – Cooling Vent Locations

20

Air-cooled 7 kW, 12 kW and 15 kW Generators

The exhaust from this product gets 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.

The maximum ambient temperature for the



generator is 48.9° C (104° F).

4.10 ATTENTION AFTER SUBMERSION

If the generator has been submerged in water, it MUST
NOT be started and operated. Following any submersion

in water, have an Authorized Dealer thoroughly clean and
dry the generator.

4.11 CORROSION PROTECTION

Periodically wash and wax the enclosure using automo­tive type products. Frequent washing is recommended
in salt water/coastal areas. Spray engine linkages with
a light oil such as WD-40.

4.12 OUT OF SERVICE PROCEDURE

4.12.1 REMOVAL FROM SERVICE



If the generator cannot be exercised every seven days,
and it is to be out of service longer than 90 days, pre­pare the generator for storage as follows:

1. Start the engine and let it warm up.

2. Close the fuel shutoff valve in the fuel supply line

and allow the unit to shut down.

3. Once the unit has shut down, it will signal a low oil

fault.

4. Set the AUTO/OFF/MANUAL switch to OFF and turn

off the utility power to the transfer switch.

5. While the engine is still warm from running, drain

the oil completely. Refill the crankcase with oil. See
”Engine Oil Recommendations,” Section 4.3.1.

6. Attach a tag to the engine indicating the viscosity

and classification of the oil in the crankcase.

7. Remove the spark plug(s) and spray fogging agent

into the spark plug(s) threaded openings. Reinstall
and tighten the spark plug(s).

8. Remove the battery and store it in a cool, dry room

on a wooden board. Never store the battery on any
concrete or earthen floor.

CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The California Air Resources Board (CARB) and Generac Power Systems, Inc. (Generac) are pleased to explain the Emission
Control System Warranty on your new engine.* In California, new utility, and lawn and garden equipment engines must be
designed, built and equipped to meet the state’s stringent anti-smog standards. Generac will warrant the emission control
system on your engine for the periods of time listed below provided there has been no abuse, neglect, unapproved modifica­tion or improper maintenance of your engine.

Your emission control system may include parts such as the carburetor, ignition system and exhaust system. Generac will
repair your engine at no cost to you for diagnosis, replacement parts and labor, should a warrantable condition occur.

MANUFACTURER’S EMISSION CONTROL SYSTEM WARRANTY COVERAGE:

Emissions control systems on 1995 and later model year engines are warranted for two years as hereinafter noted. If, dur­ing such warranty period, any emission-related component or system on your engine is found to be defective in materials or
workmanship, repairs or replacement will be performed by a Generac Authorized Warranty Service Facility.

PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:

As the engine purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory
supplied Owner’s Manual. For warranty purposes, Generac recommends that you retain all receipts covering maintenance
on your engine. However, Generac cannot deny warranty solely due to the lack of receipts or for your failure to ensure the
completion of all scheduled maintenance.

As the engine purchaser/owner, you should, however, be aware that Generac may deny any and/or all warranty coverage or
responsibility if your engine, or a part/component thereof, has failed due to abuse, neglect , improper maintenance or unap­proved modifications, or the use of counterfeit and/or “grey market” parts not made, supplied or approved by Generac.

You are responsible for contacting a Generac Authorized Warranty Service Facility as soon as a problem occurs. The
warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.

Warranty service can be arranged by contacting either your selling dealer or a Generac Authorized Warranty Service Facility.
To locate the Generac Authorized Warranty Service Facility nearest you, call our toll-free number:

1-800-333-1322

IMPORTANT NOTE: This warranty statement explains your rights and obligations under the Emission Control System
Warranty (ECS Warranty), which is provided to you by Generac pursuant to California law. See also the “Generac Limited
Warranties for Generac Power Systems, Inc.,” which is enclosed herewith on a separate sheet, also provided to you by
Generac. The ECS Warranty applies only to the emission control system of your new engine. If there is any conflict in
terms between the ECS Warranty and the Generac Warranty, the ECS Warranty shall apply except in circumstances where
the Generac Warranty may provide a longer warranty period. Both the ECS Warranty and the Generac Warranty describe
important rights and obligations with respect to your new engine.

Warranty service can be performed only by a Generac Authorized Warranty Service Facility. When requesting warranty ser­vice, evidence must be presented showing the date of the sale to the original purchaser/owner.

If there are any questions regarding the warranty rights and responsibilities, contact Generac at the following
address:

Section 10 – Warranty

Air-cooled 7 kW, 12 kW and 15 kW Generators

EMISSION CONTROL SYSTEM WARRANTY

Emission Control System Warranty (ECS Warranty) for 1995 and later model year engines:

(a) Applicability: This warranty shall apply to 1995 and later model year engines. The ECS Warranty Period shall begin on the

date the new engine or equipment is purchased by/delivered to its original, end-use purchaser/owner and shall continue
for 24 consecutive months thereafter.

(b) General Emissions Warranty Coverage: Generac warrants to the original, end-use purchaser/owner of the new engine or

equipment and to each subsequent purchaser/owner that each of its engines is ...

(1) Designed, built and equipped so as to conform with all applicable regulations adopted by the CARB pursuant to its

authority, and

(2) Free from defects in materials and workmanship which, at any time during the ECS Warranty Period, may cause a

warranted emissions-related part to fail to be identical in all material respects to the part as described in the engine
manufacturer’s application for certification.

(c) The ECS Warranty only pertains to emissions-related parts on your engine, as follows:

(1) Any warranted, emissions-related parts that are not scheduled for replacement as required maintenance in the Owner’s

Manual shall be warranted for the ECS Warranty Period. If any such part fails during the ECS Warranty Period, it shall
be repaired or replaced by Generac according to Subsection (4) below. Any such part repaired or replaced under the
ECS Warranty shall be warranted for the remainder of the ECS Warranty Period.

(2) Any warranted, emissions-related part that is scheduled only for regular inspection as specified in the Owner’s Manual

shall be warranted for the ECS Warranty Period. A statement in such written instructions to the effect of “repair or
replace as necessary” shall not reduce the ECS Warranty Period. Any such part repaired or replaced under the ECS
Warranty shall be warranted for the remainder of the ECS Warranty Period.

(3) Any warranted, emissions-related part that is scheduled for replacement as required maintenance in the Owner’s

Manual shall be warranted for the period of time prior to the first scheduled replacement point for that part. If the part
fails prior to the first scheduled replacement, the part shall be repaired or replaced by Generac according to Subsection
(4) below. Any such emissions-related part repaired or replaced under the ECS Warranty shall be warranted for the
remainder of the ECS Warranty Period prior to the first scheduled replacement point for such emissions-related part.

(4) Repair or replacement of any warranted, emissions-related part under this ECS Warranty shall be performed at no

charge to the owner at a Generac Authorized Warranty Service Facility.

(5) When the engine is inspected by a Generac Authorized Warranty Service Facility, the owner shall not be held responsible

for diagnostic costs if the repair is deemed warrantable.

(6) Generac shall be liable for damages to other original engine components or approved modifications proximately caused

by a failure under warranty of any emission-related part covered by the ECS Warranty.

(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient

to meet the expected demand for such emission-related parts.

(8) Any Generac authorized and approved emission-related replacement part may be used in the performance of any ECS

Warranty maintenance or repairs and will be provided without charge to the owner. Such use shall not reduce Generac
ECS Warranty obligations.

(9) Unapproved, add-on, modified, counterfeit and/or “grey market” parts may not be used to modify or repair a Generac

engine. Such use voids this ECS Warranty and shall be sufficient grounds for disallowing an ECS Warranty claim.
Generac shall not be held liable hereunder for failures of any warranted parts of a Generac engine caused by the use of
such an unapproved, add-on, modified, counterfeit and/or “grey market” part.

EMISSION RELATED PARTS INCLUDE THE FOLLOWING:

1) Fuel Metering System:
