7. Select an appropriate nipple or coupling that matches your shop air system (not provided). Screw the nipple/coupling into the brass opening in the front of the pump. Please use Teflon tape to insure that the attachment is airtight. Connect shop air system to this coupling and check for any air leaks.Press the counter reset button (large button on the same level as the digits of the counter) if you hear any air leaks form inside the pump housing. This should stop any further leaks inside the housing. Make sure that the 5/32 yellow/black dual hoses installed in step 3 do not leak. If there is any air loss, the hoses are not inserted adequately into the fittings. Push the hoses in to make sure they lock.
