hi marters,
this is Carlos Koo from HONG KONG, i use GRS tools. i'm happy with my GraverMach® AT and 901 airtact handpiece for the past 2 years. recently i found my handpiece not running smooth and kinda..... intermittent. The power keep dropping when i'm cutting the metal and i needa raise up the airtact pressure.
Even i tried to adjust the GraverMach air-pressure, the handpiece won't knock anymore.
i guess i correctly cleaned the handpiece, (i followed the Youtube GRS University ), at first, problem solved. but recently, its not getting any better.
any suggestions to me? the palm pad looks okay to me, not sure is it wore out.
so many thanks!
carlos
