WMH Tool Group Warranty
WMH Tool Group makes every effort to assure that its products meet high quality and durability standards
and warrants to the original retail consumer/purchaser of our products that each product be free from
defects in materials and workmanship as follows: 1 YEAR LIMITED WARRANTY ON ALL PRODUCTS
UNLESS SPECIFIED OTHERWISE. This Warranty does not apply to defects due directly or indirectly to
misuse, abuse, negligence or accidents, normal wear-and-tear, repair or alterations outside our facilities,
or to a lack of maintenance.
WMH TOOL GROUP LIMITS ALL IMPLIED WARRANTIES TO THE PERIOD SPECIFIED ABOVE,
BEGINNING FROM THE DATE THE PRODUCT WAS PURCHASED AT RETAIL. EXCEPT AS STATED
HEREIN, ANY IMPLIED WARRANTIES OR MERCHANTABILITY AND FITNESS ARE EXCLUDED.
SOME STATES DO NOT ALLOW LIMITATIONS ON HOW LONG THE IMPLIED WARRANTY LASTS,

explanation of the complaint must accompany the merchandise. If our inspection discloses a defect, we
will either repair or replace the product at our discretion, or refund the purchase price if we cannot readily
and quickly provide a repair or replacement. We will return the repaired product or replacement at WMH
Tool Groups expense, but if it is determined there is no defect, or that the defect resulted from causes
not within the scope of WMH Tool Groups warranty, then the user must bear the cost of storing and
returning the product. This warranty gives you specific legal rights; you may also have other rights, which
vary from state to state.
WMH Tool Group sells through distributors only. Members of the WMH Tool Group reserve the right to
