Being a Z9 model it should have 2 (assuming 2 group) square rocker switches and 2 dial timers the rocker switches simply operate the the groups where the dials are timers (sort of primitive automatic)
Assume is correct, 2 group and yes, the switches are there as are 2 red lights (connected to the switch) and the dials. So the switch will start/stop the extraction? Or does the dial have to be activated? No markers on the dials, so no idea how far to turn (if at all). I'm happy to do manual shots but if the dials are OK then why not? 😛
How specifically do you wish to disassemble the machine (and why?)
The machine seems to have been used/abused. One of the solenoids is new, the other looks original. One group has been used and used, the other looks clean(ish). I want to be sure there are no nasties hiding in the group head (and maybe replave the group gasket - if that is necessary?).
Good luck with the machine and give me some more details so I can try to help.
Thanks, I appreciate your info so far and look forward to next installment. I tracked down a manual for Z11 (at $5 Canadian) - can't be too much of a loss even if it is not help at all :exclamation Cheers John
