A generator that is rated more than the minimum
required peak watts will last much longer than a
generator that only supplies the exact watts needed.
To Calculate Wattage
Volts and amps can be multiplied together to get watts (volts x
amps = watts).
To Calculate Additional Start-Up Watts
(If They Are Not Listed)
For equipment with a motor: Use the rated watts
amount as an estimate of additional Start-up Watts.
For most lights or heaters:
there are no additional start-up watts.

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.

SAFETY

Limited 90 Day Warranty

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.

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.
