The Punch Tester Request Form must be filled out and faxed to the Parts Collection Center. Upon
receipt, the punch tester will be shipped via ground or second day air via UPS depending upon the
“Need By Date” requested. The tool will be shipped in a UPS Express “Large Box” measuring
18x13x3. A pre-printed UPS label will be provided for return shipping. Therefore, the same size
and style box needs to be used for return shipping. These boxes may be requested directly from
UPS if you do not have any supply of them. Using a box other than the size listed can create a delay
in return shipping, resulting in a debit. The punch tester must be returned immediately upon repair
completion. Failure to return the punch tester within two weeks of the request submission or return
of a damaged tool will result in a miscellaneous charge of $500.00 being added to the requesting
dealer’s monthly statement.
