The NU-Matic, VAK-Matic and ALL-in-ONE require clean compressed air to
function properly. A malfunction due to dirt is not a warranty issue, it's
a maintenance issue.
If you do not have proper air filters, you may
purchase one from Q.V.P. or elsewhere. Be sure to purchase the proper size
and type of filter for it to operate properly.
Please contact Q.V.P. before sending any system back. Many times problems can
be fixed on the phone. If Q.V.P. suggests you send the system back, please ship
