Emission Control System Warranty

California and United States Emission 

Control Defects Warranty Statement

The California Air Resources Board (herein CARB), the United 

States Environmental Protection Agency (herein EPA), and Harbor 

Freight Tools (herein HFT) are pleased to explain the emission control 

system warranty on your 2013 and later Small Off-Road Engine (herein 

engine). In California, the engine must be designed, built and equipped 

to meet the State’s stringent anti-smog standards.  Elsewhere within 

the United States, new off-road, spark-ignition engines certified for 

model year 2013 and later, must meet similar standards set forth by 

the EPA.  HFT must warrant the emission control system on your 

engine for the periods of time described below, provided there has 

been no abuse, neglect or improper maintenance of your engine.

Your emission control system may include parts 

such as the carburetor or fuel-injection system, and 

the ignition system. Also included may be hoses, belts, 

connectors and other emission-related assemblies.

Where a warrantable condition exists, HFT will repair your 

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

Manufacturer’s Warranty Coverage

The 2013 and later engines are warranted for two 

(2) years.  If any emission-related part on your engine is 

defective, the part will be repaired or replaced by HFT.

Harbor Freight Tools Emission Control 

Defects Warranty Coverage

Engines are warranted for a period of two (2) years relative 

to emission control parts defects, subject to the provisions 

set forth below. 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 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 engine, 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 engine owner, you should, however, be aware 

that HFT may deny you warranty coverage if your engine 

or a part has failed due to abuse, neglect, improper 

maintenance, or unapproved modifications.

•  You are responsible for shipping your engine to a HFT warranty 

station as soon as a problem exists.  Contact the HFT Customer 

Service department at the number below to make shipping 

arrangements.  The warranty repairs should be completed 

in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights 

and responsibilities, you should contact the Harbor Freight 

Tools Customer Service Department at 1-800-520-0882.

subsequent purchaser that the engine is free from 

defects in materials and workmanship that cause the 

failure of warranted parts for a period of two (2) years 

after the date of delivery to the first retail purchaser.

2.  No Charge Repair or Replacement

Repair or replacement of any warranted part will be 

performed at no charge to the owner if the work is

Customer Service Department at 1-800-520-0882.

3.  Consequential Damages Coverage

Coverage under this warranty shall also extend to the failure

warranted part while it is still covered under this warranty.

4.  Coverage Exclusions

Warranty claims shall be filed in accordance with the provisions 

of the HFT warranty policy explained in the box at the top of the 

previous page.  HFT shall not be liable for any loss of use of 

the engine, for any alternative usage, for any damage to goods, 

loss of time, or inconvenience.  Warranty coverage shall also be 

excluded for any part which fails, malfunctions, or is damaged 

due to failure to follow the maintenance and operating instructions 

set forth in the Owner’s Manual including, but not limited to:
a)  Use of parts which are not authorized by HFT
b)  Improper installation, adjustment or repair of the engine or 

of any warranted part unless performed by an authorized

are warranted for the warranty period. Any warranted part 

which is scheduled for replacement as required maintenance 

is warranted for the period of time up to the first scheduled 

replacement point for that part.  Any replacement part,
