Frequently Asked Questions
Q: What oil can I use if I am out of the recommended
oil and need to operate my generator?
A: In an emergency, oil with an API rating of SH, SJ, SK,
CF-4, CG-4, ILSAC, GF-1, GF-2 or GF-4 can be
used. It can be mineral, semi-synthetic or synthetic.
Any of the following viscosities are permissible: SAE
5W-30, 10W-30, 10W-40, 20W-50, 30 or 40 weight.
Change the oil as soon as possible using genuine
Generac oil as per the Owner’s Manual
recommendations.
Q: What needs to be done to the fuel before
extended storage?
A: First treat the remaining gasoline in the fuel tank with
a commercially available fuel stabilizer. Now the fuel
can either be drained, or left in the tank after
following proper treatment procedures. When
working with flammable gasoline, exercise all
appropriate cautions and warnings contained in this
Owner’s Manual. The sections on
Generator
Storage and Long Term Storage detail
proper storage procedures, including fuel storage
treatment.
Q: How often do I have to charge the generator’s
battery?
A: If the starter will not turn the engine over, charge the
battery using the charger provided with your
generator. The charger should be connected for no
longer than 48 hours. Charging procedures are
covered in the
Owner’s Manual.
Q: What is the proper fuel to use?
A: Regular UNLEADED gasoline is the recommended
fuel. Do not use gasoline with an ethanol
concentration greater than 10%. Do not use E85
gasoline or mix oil with gasoline. PREMIUM grade
fuel can be used, but is not required.
Q: What do the “red” and “blue” colored dots on the
extension cord receptacles mean?
A: The extension cord outlets have red and blue colored
dots at the receptacle outlet ends. These indicate the
need to balance the loads on the generator when
adding electrical devices. For example, if adding two
electrical devices, plug one into a red outlet and the
other into a blue outlet rather than two red or two blue
outlets. This will help balance the loads applied to the
generator.
Battery Charging section of this
Q: Can I operate the generator in the rain?
A: Portable generators should never be run inside an
enclosed space. However, portable generators are
intended to be used during extreme weather and for
the sensitive electronics on them, it is best if some
sort of open covering can be used to protect it from
direct rain or snow. Great options would be a car port
or boat canopy with 4 open sides or a tarp overhang
from a tree. It is very important to provide adequate
ventilation for the generator, so any sort of protection
should be at least 5 feet from any side including the
top of the unit, while in use. If protection is not
available, the unit can be used in rain or snow,
preferably with the muffler facing away from the
direction the wind/rain/snow is coming from.
Additionally, a portable generator should always be
stored inside when not in use to prevent unnecessary
wear and tear. BE ADVISED, the generator should
NEVER be used in any enclosed space including,
without limitation, a shed, home, garage, trailer or
vehicle, even if the doors are left open, as this can
damage the engine and can be a serious fire hazard
and carbon monoxide risk.
Q: How do I adjust the valve clearance?
A: Valve clearance adjustment is critical to proper
engine operation and requires special tools and
training. Instructions are covered in the
Clearance Adjustment
publication. However, if you are uncomfortable
performing this service procedure, have your dealer
maintain the generator’s valve clearance at the
intervals specified.
section of this
Valve
iv
Q: How long can I operate the generator? Does it
need a “rest” or “break”?
A: Your generator can be operated almost indefinitely.
Most important is maintaining a proper oil level. Each
time you add fuel, turn the generator off and check
the oil level and add oil, if necessary, to keep the
level at the upper mark on the dipstick. See the
Checking Oil Level and Adding Fuel sections
for instructions on adding oil and fuel.
Q: Is there anything special I need to do or unplug
my electrical devices before turning the
generator off?
A: Yes, remove all loads BEFORE turning the generator
off. Do this by turning off appliances, lights and items
being powered by the generator. Then unplug the
items from the generator’s receptacles before
allowing the generator to cool and turning the
generator off. NEVER turn the generator off while
loads are applied. Refer to the
section of the Owner’s Manual for complete
instructions on adding and removing electrical
devices.
Generator Loads
Q: The Hourmeter said it was time to service the air
filter. After the service has been performed, does
anything need to be done to the Hourmeter?
A: The Hourmeter will alert the owner continuously for
one hour before until one hour after scheduled
maintenance has been reached. Oil changes (at 100
hours) or air filter servicing (at 200 hours).
As hours of operation continue to accumulate, the
hourmeter will automatically reset itself until the next
100 or 200 hour service interval is reached. See the
Hourmeter section for additional information.
Some generators have a reset button that allows the
operator to move between maintenance intervals and
reset intervals by holding the reset button for 9
seconds. NOTE: not all generator models have the
reset button feature.
Q: The generator’s battery will no longer accept a
charge. What is the procedure for replacing with
a new battery?
A: Battery replacement procedures can be found in the
Battery Replacement section of this Owner’s
Manual.
Q: If the generator is being used during an outage,
how do I connect or disconnect electrical
devices?
A: NEVER start or stop the generator’s engine with
electrical devices plugged into the generator AND
those devices turned on. It is important that electrical
devices, that are turned on, NOT be connected to the
generator before it is operating.
• With the generator turned OFF, only connect electrical devices that are turned OFF.
The generator should never be started or stopped
when electrical devices or appliances that are
drawing electrical power are connected.
•
With the generator turned ON, electrical devices
that are turned ON or OFF may be connected.

even on equipment connected to the generator.
Ensure all appropriate covers, guards and barriers are
in place before operating the generator.
• Never handle any kind of electrical cord or device
while standing in water, while barefoot or while hands
or feet are wet. DANGEROUS ELECTRICAL SHOCK
MAY RESULT.
• The National Electric Code (NEC) requires the frame
and external electrically conductive parts of the generator be properly connected to an approved earth
ground. Local electrical codes may also require proper
grounding of the generator. Consult with a local electrician for grounding requirements in the area.
• Use a ground fault circuit interrupter in any damp or
highly conductive area (such as metal decking or steel
work).
• Do not use worn, bare, frayed or otherwise damaged
electrical cord sets with the generator.
• Before performing any maintenance on the generator,
disconnect the engine starting battery (if equipped) to
prevent accidental start up. Disconnect the cable from
the battery post indicated by a NEGATIVE, NEG or (–)
first. Reconnect that cable last.
• 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 non-conducting 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.
1.2.4 — Fire Hazards
• Gasoline is highly FLAMMABLE and its vapors are
EXPLOSIVE. Never permit smoking, open flames,
sparks or heat in the vicinity while handling gasoline.
• Never add fuel while unit is running or hot. Allow
engine to cool completely before adding fuel.
• Never fill fuel tank indoors. Comply with all laws
regulating storage and handling of gasoline.
• Do not overfill the fuel tank. Always allow room for

2.6 — BEFORE STARTING THE
ENERATOR
G
Prior to operating the generator:
• Engine oil will need to be added.
• Fill the fuel tank with unleaded fuel.
• Battery cables will need to be connected.
2.6.1 — Adding Engine Oil
The generator has been shipped WITHOUT oil. All oil
should meet minimum American Petroleum Institute
(API) Service Class SJ, SL or better. Use no special additives. Select the oil's viscosity grade according to the
expected operating temperature (also see chart).
• Above 40° F (4.4° C), use SAE 30
• Below 40° F (4.4° C) and down to 10° F (-12.2° C),
use SAE 10W-30
• All temperatures, use synthetic SAE 5W-30
2.5.4 — Idle Control Switch
In the ON position, the engine will operate at the normal
3,600 rpm to meet the demands of any loads applied.
When no loads are applied, the idle control system slows
the engine rpm to conserve fuel and lower noise levels.
Applying a load brings the engine speed back to normal
automatically.
With the switch in the OFF position, the low speed system is disabled and the engine runs at a constant 3,600
rpm, with or without a load.
Figure 2-12. Idle Control Switch
Any attempt to start the engine before it has been
properly serviced with the recommended oil may
result in an engine failure.
1. Place generator on a level surface (not to exceed 15°
in any direction).
2. Clean area around oil fill and remove oil fill cap/dipstick.
3. Wipe dipstick clean (Figure 2-13).
4. Slowly fill engine with oil through the oil fill opening.
Stop filling occasionally to check oil level. Fill until the
level is at the upper mark on the dipstick. Be careful
not to over fill.

6. Check engine oil level before starting each time
thereafter.
2.6.2 — Adding Fuel
Never fill fuel tank indoors. Never fill fuel
tank when engine is running or hot. Avoid
spilling gasoline on a hot engine. Allow
engine to cool entirely before filling fuel tank.
DO NOT light a cigarette or smoke when
filling the fuel tank.
Do not overfill the fuel tank. Always leave
room for fuel expansion. If the fuel tank is
overfilled, fuel can overflow onto a hot
engine and cause FIRE or EXPLOSION. Wipe
up any spilled fuel immediately.
Use the following instructions for adding gasoline:
Use regular UNLEADED gasoline with the generator
engine. Do not mix oil with gasoline.
Do not use gasoline with more than 10% alcohol such as
E85 or ethanol.
Clean area around fuel fill cap, remove cap.
Slowly add unleaded gasoline to fuel tank. Be careful
not to overfill (Figure 2-14).
Install fuel cap and wipe up any spilled gasoline.
Figure 2-14. Fuel Fill Level
IMPORTANT: It is important to prevent gum deposits
from forming in fuel system parts such as the carburetor,
fuel hose or tank during storage. Alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids
during storage. Acidic gas can damage the fuel system of
an engine while in storage. To avoid engine problems,
the fuel system should be emptied or treated with a commercially available fuel stabilizer before storage of 30
days or longer. See the "Storage" section. Never use
engine or carburetor cleaner products in the fuel tank as
permanent damage may occur.

Section 3 Operation
3.1 — HOW TO USE THE GENERATOR
See the "To Start the Engine" section for how to safely
start and stop the generator and how to connect and disconnect loads. If there are any problems operating the
generator, please call 1-888-77LOWES.
Never operate in an enclosed area or indoors!
NEVER use in the home, in a vehicle, or in
partly enclosed areas such as garages, EVEN
IF doors and windows are open! ONLY use outdoors and far from open windows, doors,
vents, and in an area that will not accumulate
deadly exhaust.
The engine exhaust fumes contain carbon
monoxide, which you cannot see or smell. This
poisonous gas, if breathed in sufficient concentrations, can cause unconsciousness or
even death.
Adequate, unobstructed flow of cooling and
ventilating 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 operated outdoors.
This exhaust system must be properly maintained. Do nothing that might render the
exhaust system unsafe or in noncompliance
with any local codes and/or standards.
Always use a battery operated carbon monoxide alarm indoors, installed according to the
manufacturer's instructions.
3.1.1 — Grounding The Generator When
Used As A Portable
This generator has an equipment ground that connects
the generator frame components to the ground terminals
on the AC output receptacles (see NEC 250.34 (A) for
explanation). This allows the generator to be used as a
portable without grounding the frame of the generator as
specified in NEC 250.34.
Figure 3-1. Grounding the Generator
3.1.1.1 — Special Requirements
There may be Federal or State Occupational Safety and
Health Administration (OSHA) regulations, local codes,
or ordinances that apply to the intended use of the generator.
Please consult a qualified electrician, electrical inspector,
or the local agency having jurisdiction:
• In some areas, generators are required to be registered with local utility companies.
• If the generator is used at a construction site, there
may be additional regulations which must be
observed.
3.1.2 — Connecting The Generator To A
Building’s Electrical System
When connecting directly to a building’s electrical system, it is recommended that a manual transfer switch is
used. Connections for a portable generator to a building’s
electrical system must be made by a qualified electrician
and in strict compliance with all national and local electrical codes and laws.

3.2 — GENERATOR LOADS
+
Overloading a generator in excess of its rated wattage
capacity can result in damage to the generator and to
connected electrical devices. Observe the following to
prevent overloading the unit:
• 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 label or decal
affixed to the device.
• If the appliance, tool or motor does not give wattage,
multiply volts times ampere rating to determine watts
(volts x amps = watts).
• Some electric motors, such as induction types, require
about three times more watts of power for starting
than for running. This surge of power lasts only a few
seconds when starting such motors. Make sure to
allow for high starting wattage when selecting electrical devices to connect to the generator:
1. Figure the watts needed to start the largest motor.
2. Add to that figure the running watts of all other connected loads.
The Wattage Reference Guide is provided to assist in
determining how many items the generator can operate
at one time.
NOTE:
All figures are approximate. See data label on appliance for wattage requirements.

clearance, between the intake rocker arm and valve
stem. Insert a 0.008 in. (0.20 mm) feeler gauge, for
exhaust clearance, between the exhaust rocker arm
and valve stem. Correct clearance is when a slight
drag is felt when sliding the gauge back and forth. If
the clearance is either excessively loose or tight the
rocker arms will need adjusting.
To adjust valve clearance:
1. Hold the rocker arm pivot with a wrench and loosen
the pivot lock nut (Figure 4-7).
NOTE:
The rocker arm jam nut must be held in place as the
pivot ball stud is turned.

POSITIVENEGATIVE
.
Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture
will remain around the battery for a long time
after it has been charged. The slightest spark
can ignite the hydrogen and cause an
explosion. Such an explosion can shatter the
battery and cause blindness or other serious
injury.
Do not permit smoking, open flame, sparks
or any other source of heat around a battery.
Wear protective goggles, rubber apron and
rubber gloves when working around a
battery. Battery electrolyte fluid is an
extremely corrosive sulfuric acid solution
that can cause severe burns. If spill occurs
flush area with clear water immediately.
NOTE:
The battery shipped with the generator has been fully
charged. A battery may lose some of its charge when
not in use for prolonged periods of time. If the
battery is unable to crank the engine, plug in the 12V
charger included in the accessory box. RUNNING
THE GENERATOR DOES NOT CHARGE THE
BATTERY.
NOTE:
Do not use the battery charger for more than 48
hours at one charge. Charge the battery at least once
every 3 months.

4.4 — Generator Storage
The unit should be started at least once every 30 days
and be allowed to run at least 30 minutes. If this cannot
be done and the unit must be stored for more than 30
days, use the following information as a guide to prepare
it for storage.
Allow unit to cool entirely before storage.
4.4.1 — Long Term Storage
1. Treat the fuel with a commercially available fuel stabilizer. Operate the engine for 10-15 minutes to circulate treated fuel into the fuel lines and carburetor.
Turn the fuel valve off and run the unit until it shuts
down. The fuel may be left in the tank or drained into
a suitable container.
2. Drain oil from crankcase. Refill with recommended
grade oil.
3. Remove spark plug and pour about 1/2 ounce (15
ml) of engine oil into the cylinder. Cover spark plug
hole with rag. Pull the recoil starter several times to
lubricate the piston rings and cylinder bore. A fogging
agent can be used in place of oil.
NEVER cover the generator while engine and
exhaust areas are warm.
Avoid spray from spark plug hole when cranking engine.
4. Install and tighten spark plug. Do not connect spark
plug wire.
NOTE:
Allow the unit to cool completely.
5. Clean the unit’s outer surfaces. Check that cooling
air slots and openings on the unit are open and unobstructed.
6. Store the unit in a clean, dry place.
4.4.2 — Other Storage Tips
• If possible, store the unit indoors and cover it to give
protection from dust and dirt. BE SURE TO CLOSE
THE VALVE ON THE FUEL TANK.
• Cover the unit with a suitable protective cover that
does not retain moisture.
