I am a dealer of these machines but not a distributor like I am for BintacLlc, but I will honor a 30 day warranty and exchange them after 30 days you will have to contact the manufacturer as they have a 90 day manufacturer warranty! The secret to these is to keep these under 50° Celsius when they're using them and make sure you let them run after you're done airing up the gun until it gets cooled down to 30° Celsius at least and they will last a while
