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

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.
