WARRANTY

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 a period of two years 
from date of purchase. 
(90 days if used by a professional contractor or if used as rental equipment).

This warranty does not apply to damage due directly or indirectly to misuse, abuse,
negligence or accidents; repairs or alterations outside our facilities; or 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.  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 the 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.
