Hi Bill, the same what suggested Vic, the pressed air gun (like reverse-connected vacuum cleaner tool) to blow the dust out I am using in our company for rough cleaning of the testing equipment time to time.
Important things are to protect fans (as Vic mentioned too) from the over-spining. After that when the dust is roughly out I am repeating this step again on different place (if you did not do it outside for the first time) to blow the settled residual dust from the all boards. After all of these steps I am removing the boards one by one and cleaning the pins and all contact with Isopropyl on the cleaning pad. It takes time but it will surely pay! In any case during all of that cleaning procedure I am protecting all LCD displays and screens with covers (adhesive paper tape) in order to avoid getting the dust under the plastic covers, glass screens etc. by the high pressed air gun... Hope it helps, 73 - Petr, OK1RP ----- http://ok1rp.blogspot.com -- View this message in context: http://elecraft.365791.n2.nabble.com/Cleaning-a-K3-tp7620745p7620747.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
