[3dem] Gatan 655/626 Maintenance

[Tobias Furstenhaupt]

Hi Bradley,

I can only second Patricia's email: We have said pumping station and each time, when the vacuum reading was 'very bad", cleaning the gauge did the trick. This might range from blowing out the dirt to disassembly and cleaning the parts - just as Patricia described :)
It is easy, fast and very satisfying (as the result is immediate)

cheers 
Tobias
