1. nO FLaMeS Or SparKS!

Immediately put out all smoking

materials and other open flames.

Do not operate lights, appliances,

telephones, or cell phones.

Flames or sparks from these sources

can trigger an explosion or a fire.

2. LeaVe THe area iMMeDiaTeLy!

Get everyone out of the building or

area where you suspect gas is leaking.

3. SHuT OFF THe GaS.

Turn off the main gas supply

valve on your propane tank if it is

safe to do so. To close the valve,

turn it to the right (clockwise).

4. repOrT THe LeaK. From a

neighbor’s home or other nearby

building away from the gas leak,

call your propane retailer right away.

If you can’t reach your propane retailer,

call 911 or your local fire department.

5. DO nOT reTurn TO THe BuiLDinG

Or area until your propane

retailer, emergency responder,

or qualified service technician

determines that it is safe to do so.

6. GeT yOur SySTeM CHeCKeD.

Before you attempt to use any of

your propane appliances, your

propane retailer or a qualified service

technician must check your entire

system to ensure that it is leak-free.

Can yOu SMeLL iT?

Propane smells like rotten eggs, a skunk’s

spray, or a dead animal. Some people

may have difficulty smelling propane

due to their age (older people may

have a less sensitive sense of smell);

a medical condition; or the effects of

medication, alcohol, tobacco, or drugs.

ODOr LOSS. On rare occasions,

propane can lose its odor. Several

things can cause this including:

•

The presence of air, water, or rust

in a propane tank or cylinder

•

The passage of leaking

propane through the soil

Since there is a possibility of

odor loss or problems with

your sense of smell, you

should respond immediately

to even a faint odor of gas.

prOpane GaS DeTeCTOrS

Under some circumstances, you may

not smell a propane leak. Propane gas

detectors (not included) sound an alarm if

they sense propane in the air. They can

provide an additional measure of security.

You should consider the purchase of

one or more detectors for your home.

GuiDeLineS regarding

propane gas detectors:

•

Buy only units that are listed

under the latest Underwriters

Laboratories (UL) standard.

•

Follow the manufacturer’s

instructions regarding installation

and maintenance.

•

Never ignore the smell of

propane, even if no detector

is sounding an alarm.

appLianCe MainTenanCe

LeaVe iT TO THe eXperTS.

Only a qualified service technician has

the training to install, inspect, service,

maintain, and repair your appliances.

Have your appliances and propane

system inspected just before the

start of each heating season.

DO nOT Try TO MODiFy Or repair

valves, regulators, connectors, controls, or

other appliance and cylinder/tank parts.

Doing so creates the risk of a gas leak

that can result in property damage,

serious injury, or death.

CO anD yOur SaFeTy

WHaT iS CarBOn MOnOXiDe (CO)?

You can’t taste or smell CO, but it is a

very dangerous gas. High levels of CO

can come from appliances that are not

operating correctly, or from a venting

system or chimney that becomes blocked.

CO Can Be DeaDLy! High levels of CO

can make you dizzy or sick. In extreme

cases, CO can cause brain damage

or death. Symptoms of CO poisoning

include: headache, dizziness, fatigue,

shortness of breath, and nausea.

iF yOu SuSpeCT CO iS

preSenT, aCT iMMeDiaTeLy!

1. If you or a family member shows

physical symptoms of CO poisoning,

get everyone out of the building and

call 911 or your local fire department.

2. If it is safe to do so, open windows

to allow entry of fresh air, and

turn off any appliances you

suspect may be releasing CO.

3. If no one has symptoms, but you

suspect that CO is present, call

your propane retailer or a qualified

service technician to check CO levels

and your propane equipment.

CO DeTeCTOrS Can iMprOVe

SaFeTy. For an extra measure

of safety, consider installing a CO

detector (not included) listed by UL

on each level of your home.

TO HeLp reDuCe THe riSK

Connecting electrical Loads to the Generator

Calculate power Draw

Power draw can be calculated by multiplying volts and amps. The resulting number is wattage.

• The total combined load through the outlets on the Generator must not exceed the running power

of the unit. Never exceed the running wattage for the Generator or any outlet amperage rating.

• Refer to appliance/tool owner’s manuals to determine the wattage of electrical load devices.

• Long power cords and extension cords draw additional power. Keep cord length at a minimum.

WarninG! Never exceed the rated capacity for this Generator, as serious damage to the Generator and/or

appliances, tools, and equipment could result from an overload. Starting and running wattage requirements should

always be calculated when matching this Generator’s wattage capacity to the appliance, tool, or equipment.

Wattage estimates

Refer to your device documentation for start-up and running wattage requirements.

Check nameplate wattages on all loads before connecting to Generator.

Plug the power cord of the 120 volt appliance/tool into the appropriate Outlet on

the Generator. Plug in appliances from largest to smallest load.

Connect the items that require the most wattage first.

a. Connect “inductive” load appliances, tools, and equipment next. Inductive

loads are small hand tools and some small appliances.

b. Connect any lights next.

iMpOrTanT! Failure to connect and operate appliances, tools, and equipment in this sequence can cause

damage to the Generator, appliances, tools, and equipment and will void the Warranty of this Generator.

Overload indicator

note: The OVERLOAD light may turn on for a few seconds as a large device starts up.

This is normal for loads approaching the capacity of this Generator.

1. The total combined load through the outlet on the Generator must not exceed the running power of the unit.

2. When approaching maximum running power, the OVERLOAD light will blink. If the OVERLOAD

light turns on continuously and the Generator stops producing power, it has been overloaded.

3. Turn off and disconnect all electrical devices. Compare device requirements to Generator rating and reduce the

Limited 90 Day Warranty (retail)

Harbor Freight Tools Co. makes every effort to assure that its products meet high quality and durability standards,

and warrants to the original purchaser that this product is free from defects in materials and workmanship for the

period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,

to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper

installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries

to persons or property, or for incidental, contingent, special or consequential damages arising from the use of

our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so

the above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL

OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY

AND FITNESS, EXCEPT FOR THE EMISSIONS CONTROL SYSTEM WARRANTY BELOW.

To take advantage of this warranty, the product or part must be returned to us with transportation charges prepaid.

Proof of purchase date and an explanation of the complaint must accompany the merchandise. If our

inspection verifies the defect, we will either repair or replace the product at our election or we may elect to

refund the purchase price if we cannot readily and quickly provide you with a replacement. We will return

repaired products at our expense, but if we determine there is no defect, or that the defect resulted from

causes not within the scope of our warranty, then you must bear the cost of returning the product.

This warranty gives you specific legal rights and you may also have other rights which vary

from state to state. HFT also warrants that the emissions control system on your engine is

designed, built, and equipped so that it conforms to the United States Environmental Protection

Agency’s (EPA) emissions requirements in effect at the time of manufacture.

emissions Control System Warranty

The California Air Resources Board and Harbor Freight Tools (HFT) are pleased to explain the emissions control

system warranty on your 2025 Small Off-Road Engine and engine powered equipment. In California, new equipment

that uses Small Off-Road Engine must be designed, built, and equipped to meet the State’s stringent anti-smog

standards. HFT must warrant that the emissions control system on your Small Off-Road Engine and engine powered

equipment will be free from defects in material and workmanship for two (2) years, provided there has been no

abuse, neglect, or improper maintenance of your Small Off-Road Engine or engine powered equipment. HFT also

warrants that the emissions control system on your engine is designed, built, and equipped so that it conforms to the

United States Environmental Protection Agency’s (EPA) emissions requirements in effect at the time of manufacture.

Your emissions control system may include parts such as: carburetor or fuel-injection system,

the ignition system, catalytic converter, fuel lines, fuel tanks, fuel caps, valves, canisters, filters,

hoses, belts, clamps, connectors, and other emission-related assemblies or components.

Where a warrantable condition exists, HFT will repair or replace, at our option,

your engine at no cost to you, including diagnosis, parts and labor.

ManuFaCTurer’S WarranTy COVeraGe

This emissions control system is warranted for two years. If any emission-related

part on your engine is defective, the part will be repaired or replaced by HFT.

OWner’S WarranTy reSpOnSiBiLiTieS

As the Small Off-Road Engine and engine powered equipment owner, you are responsible for the

performance of the required maintenance listed in your Owner’s Manual. HFT recommends that you retain

all receipts covering maintenance on your Small Off-Road Engine/equipment, but HFT cannot deny warranty

solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the Small Off-Road Engine and engine powered equipment owner, you should however be

aware that HFT may deny you warranty coverage if your Small Off-Road Engine or engine powered

equipment or a part has failed due to abuse (including failure to follow the fuel use instructions

contained in this manual), neglect, improper maintenance, or unapproved modifications.

You are responsible for presenting your Small Off-Road Engine or engine powered equipment to

HFT as soon as the problem exists. To obtain warranty repair or replacement, either: (a) contact HFT

Product Support at 1-800-444-3353 or [email protected] or (b) bring the Small Off-

Road Engine or engine powered equipment to your nearest Harbor Freight Tools retail store. The nearest

Harbor Freight Tools retail store can be found on the internet at https://www.harborfreight.com. The warranty

repairs or replacement should be completed in a reasonable amount of time, not to exceed 30 days.

If you have a question regarding your warranty coverage, you should contact HFT

Product Support at 1-800-444-3353 or [email protected].

GeneraL eMiSSiOnS WarranTy COVeraGe

a) The warranty period begins on the date the engine or equipment is delivered

to an ultimate purchaser. The warranty period is two years.

b) HFT warrants to the ultimate purchaser and each subsequent owner that the engine is:

1. Designed, built, and equipped so as to conform with the applicable United States Environmental

Protection Agency’s (EPA) emissions requirements in effect at the time of manufacture

and all applicable regulations adopted by the California Air Resources Board; and

2. Free from defects in materials and workmanship that cause the failure of a warranted

part to be identical in all material respects to the part as described in the engine

manufacturer’s application for certification for a period of two years.

c) The warranty on emissions-related parts is as follows:

1. Any warranted part that is not scheduled for replacement as required maintenance in the written

instructions provided is warranted for the warranty period stated above. If any such part fails

during the period of warranty coverage, it will be repaired or replaced by HFT. Any such part

repaired or replaced under the warranty will be warranted for the remaining warranty period.

2. Any warranted part that is scheduled only for regular inspection in the written instructions is

warranted for the warranty period stated above. A statement in the written instructions to the effect

of “repair or replace as necessary” does not reduce the period of warranty coverage. Any such

part repaired or replaced under warranty will be warranted for the remaining warranty period.

3. Any warranted part that is scheduled for replacement as required maintenance in the written

instructions will 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 will be repaired

or replaced by HFT. Any such part repaired or replaced under warranty will be warranted for

the remainder of the period prior to the first scheduled replacement point for the part.

4. At no charge to the owner, repair or replacement of any warranted part under the warranty

will be performed at a retail store or by HFT shipping the product for repair.

5. Notwithstanding the provisions herein, warranty services or repairs will be provided at all retail stores

or by contacting HFT Product Support at 1-800-444-3353 or [email protected].

6. The owner will not be charged for diagnostic labor that leads to the determination that a warranted

part is in fact defective, provided that such diagnostic work is performed at a retail store.

7. HFT is liable for damages to other engine components proximately

caused by a failure under warranty of any warranted part.

8. Throughout the engine’s and emission control system’s warranty period stated above,

HFT will maintain a supply of warranted parts sufficient to meet the expected demand

for such parts and will obtain additional parts if that supply is exhausted.

9. Any replacement part may be used in the performance of any warranty maintenance or repairs and

will be provided without charge to the owner. Manufacturer-approved replacement parts that do not

increase emissions will be used in the performance of any warranty maintenance or repairs and will

be provided without charge to the owner. Such use will not reduce the warranty obligations of HFT.

10. Add-on or modified parts that are not exempted by the California Air Resources Board may not be used. The

use of any non-exempted add-on or modified parts will be grounds for disallowing a warranty claim. HFT is

not liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.

11. HFT will provide any documents that describe its warranty procedures

or policies upon request of the Executive Officer.
