Third party modifications will void your AirGraver® warranty.
It has come to my attention that someone may be attempting to sell a modification to the AirGraver® by incorporating or cannibalizing our foot control idle apparatus into their product. I have requested this individual not to do this as it causes problems with AirGaver® warranty and service as well as possibly legal implications. The AirGraver® has multiple patents and claims protecting it as well as the foot controller apparatus itself.
It is our policy that purchasing or using a 3rd party add-on or modification to your AirGraver will void the warranty. This is because I cannot endorse or recommend modification to my product and then continue to support it when it does not work and is not configured as it was designed.
Thank you, Steve Lindsay
