Warranties
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, the United States Environmental Protection Agency, and
Harbor Freight Tools (HFT) are pleased to explain the exhaust and evaporative emissions (“emissions”) control
system warranty on your [Model Year] Small Off-Road Engine, in addition to the Retail Warranty above. In California,
new equipment that uses small off-road engines 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 will be free
from defects in material and workmanship for the period listed below, provided there has been no abuse, neglect,
or improper maintenance of your small off-road engine leading to the failure of the emissions control system.
Your emissions control system may include parts such as the carburetor or fuel-injection
system, the ignition system, catalytic converter, fuel tanks, fuel lines (for liquid fuel and fuel
vapors), fuel caps, valves, canisters, filters, clamps, and other associated components.
Also included may be hoses, belts, connectors, and other emissions-related assemblies.
Where a warrantable condition exists, HFT will repair or replace, at our option,
your engine if at no cost to you, including diagnosis, parts and labor.
ManuFaCTurer’S WarranTy COVeraGe
The exhaust and evaporative emissions control system on your small off-road engine is warranted for two years.
If any emission-related part on your small off-road engine is defective, the part will be repaired or replaced by HFT.
OWner’S WarranTy reSpOnSiBiLiTieS
As the small off-road engine 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, but HFT cannot deny warranty coverage solely for the
lack of receipts or for your failure to ensure the performance of all scheduled maintenance.
As the small off-road engine owner, you should however be aware that HFT may deny you warranty
coverage if your small off-road engine or a part has failed due to abuse (including failure to follow the fuel use
instructions contained in this manual), neglect, or improper maintenance or unapproved modifications.
You are responsible for contacting HFT as soon as the problem exists in order to obtain warranty
repair or replacement, by doing either of the following: (a) contact HFT product support at 1-800-444-3353
or [email protected]; or (b) bring the 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].

DeFeCTS WarranTy reQuireMenTS:
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 owner and each subsequent owner that the engine or equipment is:
1. Designed, built, and equipped so as to conform with all applicable
regulations adopted by the Air Resources Board; and
2. Free from defects in materials and workmanship that causes the
failure of a warranted part 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 must be warranted for the warranty period stated above. If any such part fails during the
period of warranty coverage, it will be repaired or replaced HFT according to Subsection (4) below. Any
such part repaired or replaced under the warranty must be warranted for the remaining warranty period.
2. Any warranted part that is scheduled only for regular inspection in the written instructions
must be warranted for the warranty period defined in Subsection (b)(2). A statement in such
written instructions to the effect of “repair or replace as necessary” shall advise owners of
the warranty coverage for emissions related parts. Replacement within the warranty period is
covered by the warranty and will not reduce the period of warranty coverage. Any such part
repaired or replaced under warranty must be warranted for the remaining warranty period.
3. Any warranted part that is scheduled for replacement as required maintenance in the written
instructions must 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 must be repaired
or replaced by HFT. Any such part repaired or replaced under warranty must be warranted for
the remainder of the period prior to the first scheduled replacement point for the part.
4. Repair or replacement of any warranted part under the warranty provisions must be performed at
no charge to the owner at a retail store or by HFT paying for shipping the product for repair.
5. Notwithstanding the provisions herein, warranty services or repairs must be provided at
all retail stores that are franchised to service the subject engine or by contacting HFT
product support at 1-800-444-3353 or [email protected].
6. The owner must 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 emissions control system’s warranty period stated above, HFT must
maintain a supply of warranted parts sufficient to meet the expected demand for
such parts and must obtain additional parts if that supply is exhausted.
9. Manufacturer-approved replacement parts that do not increase the exhaust or evaporative emissions of the
engine or emissions control system must be used in the performance of any warranty maintenance or repairs
and must 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 Air Resources Board may not be used. The use of
any non-exempted add-on or modified parts may be grounds for disallowing a warranty claim. HFT will not be
liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified part.
11. HFT issuing the warranty shall provide any documents that describe that warranty
procedures or policies within five working days of request by the Executive Officer.
