The Progressive Foot Control for my GraverMax SC has started to hiss air and is intermittent in operation. I haven't changed anything so I'm a bit perplexed. My handpiece is "tuned" properly...
I took the hose off and looked it over at all angles and dusted it out as best I could. The exploded parts view in the manual doesn't show any seals that could have gone bad.
Any ideas? I may have to call GRS.
