INTRODUCTION
Briggs and Stratton has made every effort to provide for a
safe, streamlined and cost-effective installation. Because
each installation is unique, it is impossible to know of and
advise the trade of all conceivable procedures and methods
by which installation might be achieved. Neither could we
know of possible hazards and/or the results of each
method or procedure. For these reasons,
Only current qualified electrical contractors
should attempt HGS Installations.
Installations must strictly comply with
all applicable codes, industry standards
and regulations.
Your Briggs & Stratton Home Generator System is supplied
with this “Owners Manual” and a separate “Installation

documents and should be retained by the owner after the
installation has been completed.
WARNING! Per National Electric Code,
connection of a generator to any electrical circuit
normally powered by an electric utility must be by
means of approved transfer switch equipment so as
to isolate the electrical circuit from the utility
distribution system when the generator is operating.
Failure to isolate the electrical circuits by such
means may result in injury or death to utility power
workers due to backfeed of electrical energy.
The semi-automatic transfer switch is suitable for use in
accordance with Article 702 of the National Electric Code,
ANSI/NFPA 70.This switch is suitable for use on a circuit
capable of delivering not more than 10000A RMS,
symmetrical current, 120/240V, when installed on the load
side of appropriate branch circuit. For indoor use only.The
connection box is a NEMA type 3R, intended for outdoor
use.

Essential Circuits
As a Home Generator System owner, it is important that
you clearly identify the circuits in your building that are
"essential" to you.Your Home Generator System is
equipped with a Semi-Automatic
Transfer Switch.When
properly wired, your selection of essential circuits will be
transferred to the generator power within 10 seconds
(+/- 5 seconds) after the generator is connected and started.
It is important that your installer understand which
circuits
you want to include as "Essential Circuits". Depending on
the power consumed by these circuits,most or all of them
can be switched to the Home Generator System for the
duration of normal power interruption.
The wattage reference guide shown in Figure 3 will assist
you with your decision-making process.It provides the
wattage used by many ordinary household devices. Use it as
a guide when selecting your essential circuits. Review this
information with your installer and ask about any technical
considerations that might affect the cost of your installation.
Essential Circuit Selection
When selecting the essential circuits that will be switched to
“Backup Power,” it is important that the sum of the combined
circuit loads does not exceed the wattage/amperage capacity
of the generator.To help you with your selection of essential
circuits, please consider the following:
Add up the total wattage of all electrical devices to be
connected at one time.This total should NOT be
greater than the generator’s wattage capacity.
The rated wattage of lights can be taken from light bulbs.
The rated wattage of tools, appliances and motors can
usually be found on a data plate or decal affixed to the
device.
If the appliance, tool or motor does not give wattage,
multiply 120 Volts times the ampere rating to determine
Watts (Volts x Amps = Watts).
Some electric motors (induction types) require about
three times more watts of power for starting than for
running.This surge lasts for only a few seconds. Be sure
you allow for this high starting wattage when selecting
electrical devices that will be energized by the Home
Generator System:
Figure the watts required to start the largest motor.
Add that to the total running watts of all other
connected loads.

GROUNDING THE
GENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local
electrical codes may also require proper grounding of the
unit.Whenever the unit is connected to the system’s
properly installed power inlet box, the generator is
automatically connected to the building’s grounding system.
IMPORTANT: When operating the unit as a stand-alone
generator, the unit should
be connected to a grounding
rod, especially when the unit is equipped with a wheel kit.
Properly grounding the generator helps prevent electrical
shock if a ground fault condition exists in the generator or
in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in
ungrounded devices.
A GROUNDING WING NUT is provided (Figure 7) to
make the grounding attachment.
Connecting a No. 12 AWG (American Wire Gauge)
stranded copper wire to the grounding wing nut and to an
earth–driven copper or brass grounding rod (electrode)
provides adequate protection against electrical shock.
CAUTION! Do Not connect the unit to a
grounding rod at the same time it is connected to
the building’s power inlet box.
OPERATING THE
GENERATOR
CAUTION! Never start or stop unit with
electrical loads connected AND with the connected
devices turned ON.
IMPORTANT: Always unplug the battery float charger
before starting the generator.
Starting the Engine
Disconnect all electrical loads from the generator. Use the
following start instruction steps by numerical order:
1. Move the fuel valve to the “On” position (Figure 8).
2. To start a cold engine, move the choke lever to the
“Choke” position. To restart a warm engine, leave
the choke lever in the “Run” position (Figure 9).

Owners Manual
This receptacle powers 120/240 Volt AC, 60 Hz,single
phase loads requiring up to 3600 Watts of power at
30 Amps for 120 Volts; 6500 Watts of power (6.5 kW) at
27.1 Amps for 240 Volts.The outlet is protected by a
30 Amp circuit breaker.
CAUTION! Although this outlet states it has a
240 Volt 30 Amp rating (up to 7,200 Watts), the
generator is only rated for 6,500 Watts. Powering
loads that exceed the wattage/ amperage capacity of
the generator can damage it or cause serious
injuries. 240 Volt loads powered through this outlet
should not exceed 27.1 Amps of current draw.
Light
A light is provided on the control panel to assist movement
in the dark.Turn on the light using the switch on the
control panel.
Always turn off the light when not needed as it drains the
generator battery.Turn off the light when the generator is
running.
How to Use the Battery Charger
Use the battery float charger jack to keep the starting
battery charged and ready for use. Battery charging should
be done in a dry location, such as inside a garage.
• Plug the charger into the unit’s “12V DC Float Charger”
jack, which is located on the control panel (Figure 13).
Plug battery charger into a 120 Volt AC wall receptacle.
• Unplug the charger from the unit and the wall outlet when
generator is being started and while it is in operation.
• Keep this charger plugged in when generator is not in
use to prolong battery life.The charger has a built in float
equalizer and will not overcharge the battery, even when
plugged in for an extended period of time.
IMPORTANT: See “Battery Maintenance” on page 17 for
additional information.

DON'T OVERLOAD YOUR
GENERATOR
NOTE: Refer to this section when you are using the
generator without the semi-automatic transfer switch.Ask
your semi-automatic transfer switch installer to review load
management techniques. See “Essential Circuits” on page 6.
Capacity
You must make sure your generator can supply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:
1. Select the items you will power at the same time.
2. Total the rated (running) watts of these items.This is
the amount of power your generator must produce to
keep your items running. See Figure 14.
3. Estimate how many surge (starting) watts you will
need. Surge wattage is the short burst of power
needed to start electric motor-driven tools or
appliances such as a circular saw or refrigerator.
Because not all motors start at the same time, total
surge watts can be estimated by adding only the
item(s) with the highest additional surge watts to the
total rated watts from step 2.
Example:
Total Rated (Running) Watts = 3075
Highest Additional Surge Watts = 1800
Total Generator Output Required = 4875
Power Management
To prolong the life of your generator and attached devices,
it is important to take care when adding electrical loads to
your generator. There should be nothing connected to the
generator outlets before starting it's engine.The correct
and safe way to manage generator power is to sequentially
add loads as follows:
1. With nothing connected to the generator, start the
engine as described in this manual.
2. Plug in and turn on the first load, preferably the largest
load you have.
3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly.
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilize.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity.Take
special care to consider surge loads in generator capacity,
as described above.
*Wattages listed are approximate only. Check tool or
appliance for actual wattage.

OPERATING THE POWER
TRANSFER SWITCH
Switch To Generator Power
To switch to generator power after a utility power failure:
1. Align the female socket of the power cord with the
connection box receptacle’s mating male prongs, as
shown in Figure 15. Push power cord connector in and
twist clockwise to lock.
2. Align the male prongs on the other end of the power
cord with the mating female terminals of the
generator’s 240V receptacle, as shown in Figure 16.
Push in connector and twist clockwise to lock.
3. Ensure generator is outdoors and fluids and fuel are
topped-off.
4. Open the main circuit breaker on the generator
control panel. Start the generator using instructions
given in the section “Operating the Generator” on
page 11.
5. Close the generators main circuit breaker.
6. After a ten second delay, the transfer switch will
transfer essential circuit loads to the generator.
Load Management
The number of circuits that can be operated simultaneously
during a utility failure will depend on the wattage capacity of
your generator. Most portable generators do not have
the capacity to handle loads on all circuit breakers
at the same time.
Review the load management plan developed with the
installer (see “Plan the Installation” in the Installation
manual, P/N 190854). It may be necessary to selectively turn
on and off certain loads while using generator power so
that necessary appliances can be operated safely.

GENERAL MAINTENANCE
RECOMMENDATIONS
The Owner/Operator is responsible for making sure that
all periodic maintenance tasks are completed on a timely
basis; that all discrepancies are corrected; and that the unit
is kept clean and properly stored. Never operate a
damaged or defective generator.
Engine Maintenance
See engine owner’s manual for instructions.
CAUTION! Avoid prolonged or repeated skin
contact with used motor oil. Used motor oil has
been shown to cause skin cancer in certain
laboratory animals.Thoroughly wash exposed areas
with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN
USED OIL TO COLLECTION CENTERS.
Generator Maintenance
Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean dry
environment where it will not be exposed to excessive
dust, dirt, moisture or any corrosive vapors. Cooling air
slots in the generator must not become clogged with snow,
leaves or any other foreign material.
NOTE: Do Not use a garden hose to clean generator.
Water can enter engine fuel system and cause problems. In
addition, if water enters generator through cooling air slots,
some of the water will be retained in voids and cracks of
the rotor and stator winding insulation.Water and dirt
buildup on the generator internal windings will eventually
decrease the insulation resistance of these windings.
Battery Maintenance
Other than float charging, described elsewhere, no
maintenance is required for the battery. Keep the battery
and terminals clean and dry.
IMPORTANT: Battery charging should be performed in a
dry location, such as inside a garage.
To Clean the Generator
• Use a damp cloth to wipe exterior surfaces clean.
• A soft bristle brush may be used to loosen caked on dirt
or oil.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and opening on
generator.These openings must be kept clean and
unobstructed.
18
Briggs & Stratton Power Products Home Generator System
Owners Manual
STORAGE
The generator should be started at least once every seven
days and allowed to run at least 15 minutes. If this cannot
be done and you must store the unit for more than 30 days,
use the following guidelines to prepare it for storage.
Generator Storage
• Clean the generator as outlined in “To Clean the Generator.”
