2.3.2 CONNECTING ELECTRICAL LOADS
DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT
connect 3-phase loads to the generator. DO NOT connect 50 Hz
loads to the generator.
Let engine stabilize and warm up for a few minutes after •
starting.
Plug in and turn on the desired 120 or 240 Volt AC, single •
phase, 60 Hz electrical loads.
Add up the rated watts (or amps) of all loads to be connected •
at one time. This total should not be greater than (a) the rated
wattage/amperage capacity of the generator or (b) circuit
breaker rating of the receptacle supplying the power. See "Don't
Overload the Generator".
NEVER use in the home or in partly enclosed areas such as garages.
ONLY use outdoors and far from open windows, doors and vents.
2.3.1 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 (Figure 7).
Local electrical codes may also require proper grounding of the
unit. For that purpose, connecting a No. 10 AWG (American Wire
Gauge) stranded copper wire to the grounding lug and to an
ear th-driven copper or brass grounding rod (electrode) provides
adequate protection against electrical shock. However, local codes
may vary widely. Consult with a local electrician for grounding
requirements in the area.
Proper grounding of the generator will help prevent electrical
shock in the event of a ground fault condition in the generator
or in connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in ungrounded
devices.

2.4 DON’T OVERLOAD THE GENERATOR
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 star ting than for running.
This surge of power lasts only a few seconds when star ting
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.

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 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.

or in extremely hot weather, change the oil more often.
Hot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeated
skin exposure with used oil. Thoroughly wash
exposed areas with soap.

Section 3 — Maintenance
Portable Generator System
NOTE:
To order a new air filter, please contact the nearest authorized
service center at 1-888-436-3722.
After the first 50 hours of operation, check the valve clearance
in the engine and adjust if necessary.
Important: If feeling uncomfortable about doing this procedure or
the proper tools are not available, please take the generator to the
nearest service center to have the valve clearance adjusted. This is
a very important step to ensure longest life for the engine.
3.6 GENERAL
The generator should be star ted at least once every seven 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.
DANGER
NEVER store engine with fuel in tank indoors
or in enclosed, poorly ventilated areas where
fumes may reach an open flame, spark or pilot
light as on a furnace, water heater, clothes dryer
or other gas appliance.
3.7 LONG TERM STORAGE
It is impor tant to prevent gum deposits from forming in essential
fuel system par ts such as the carburetor, fuel hose or tank during
storage. Also, experience indicates that 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
before storage of 30 days or longer, as follows:
Remove all gasoline from the fuel tank.•
DANGER
Drain fuel into approved container outdoors,
away from open flame. Be sure engine is cool.
Do not smoke.
Star t and r un engine until engine stops from lack of fuel.•
While engine is still warm, drain oil from crankcase. Refill with •
recommended grade.
Remove spark plugs and pour about 1/2 ounce (15 ml) of •
engine oil into the cylinders. Cover spark plug hole with rag.
Pull the recoil starter a couple times to lubricate the piston rings
and cylinder bore.
Avoid spray from spark plug holes when
cranking engine.
Install and tighten spark plugs. Do not connect spark plug •
wires.
Clean the generator outer surfaces. Check that cooling air slots •
and openings on generator are open and unobstructed.
Store the unit in a clean, dry place.•
3.8 OTHER STORAGE TIPS
Do not store gasoline from one season to another.•
Replace the gasoline can if it starts to r ust. Rust and/or dir t in •
the gasoline will cause problems with the carburetor and fuel
system.
If possible, store the unit indoors and cover it to give protection •
from dust and dir t. BE SURE TO EMPTY THE FUEL TANK.
If it is not practical to empty the fuel tank and the unit is to be •
stored for some time, use a commercially available fuel stabilizer
added to the gasoline to increase the life of the gasoline.
Cover the unit with a suitable protective cover that does not •
retain moisture.
DANGER
NEVER cover the generator while engine and
exhaust areas are warm.

FEDERAL EMISSION CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
The United States Environmental Protection Agency (EPA) and Generac Power Systems, Inc. (Generac) are pleased to explain the
Emission Control System warranty on your new 2008 and later equipment. New equipment that use small spark-ignited engines
must be designed, built, and equipped to meet stringent anti-smog standards for the federal government. Generac will warrant
the emission control system on your generator for the period of time listed below provided there has been no abuse, neglect,
unapproved modification or improper maintenance of your equipment.
Your emission control system may include parts such as the: carburetor, ignition system, fuel system, catalytic converter, and other
associated emission-related components (if equipped).
MANUFACTURER’S WARRANTY COVERAGE:
This emission control system is warranted for two years. If, during such warranty period, any emission-related part on your
equipment is found to be defective in materials or workmanship, repairs or replacement will be performed by a Generac
Authorized Warranty Service Dealer.
OWNER'S WARRANTY RESPONSIBILITIES:
As the generator 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
generator, but Generac cannot deny warranty solely due to the lack of receipts.
As the generator owner, you should be aware that Generac may deny any and/or all warranty coverage or responsibility if your
generator, 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 Dealer 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 Dealer. To

(ECS Warranty), which is provided to you by Generac pursuant to federal 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. Note that this
warranty shall not apply to any incidental, consequential or indirect damages caused by defects in materials or workmanship or
any delay in repair or replacement of the defective part(s). This warranty is in place of all other warranties, expressed or implied.
Specifically, Generac makes no other warranties as to the merchantability or fitness for a particular purpose. Some states do not
allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
The ECS Warranty applies only to the emission control system of your new equipment. If there is any conflict in terms between the
ECS Warranty and the Generac Warranty, the Generac Warranty shall apply. 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 you have any questions regarding your warranty rights and responsibilities, you should contact Generac at the following

Emission Control System Warranty (ECS warranty) for equipment using small spark-ignited engines:
(a) Applicability: This warranty shall apply to equipment that uses small off-road engines. The ECS Warranty period shall begin
on the date the new 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 the ECS when installed was:
(1) Designed, built and equipped so as to conform with all applicable regulations; and
(2) Free from defects in materials and workmanship which cause the failure of a warranted part at any time during the ECS
Warranty Period.
(c) The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is 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 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 the Owner’s Manual 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 part that is scheduled for replacement as required maintenance in the Owner's Manual shall be warranted
for the period of time prior to 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 emissionsrelated part repaired or replaced under the ECS warranty shall be warranted for the remainder of the period prior to the
first scheduled replacement point for that 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) Notwithstanding the provisions of subsection (4) above, warranty services or repairs must be provided at Generac
Authorized Service Facilities.
(6) When the engine is inspected by a Generac Authorized Warranty Service Facility, the purchaser/owner shall not be held
responsible for diagnostic costs if the repair is deemed warrantable.
(7) Throughout the ECS Warranty Period, Generac shall maintain a supply of warranted emission-related parts sufficient to
meet the expected demand for such parts.
(8) Any Generac authorized and approved emission-related replacement parts may be used in the performance of any ECS
warranty maintenance or repairs and will be provided without charge to the purchaser/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
