CZ-5 problem?

I've got a CZ-5 that has been working great,but recently I've noticed that when I adjust the volume control it seems to cut out the power to the detector.
If I wiggle the volume back and forth the detector fires back up and works well until I try to adjust the volume control again.
I'm wondering how to remove the control nobs...thinking maybe try some switch cleaner on the volume control....
But I'm not sure how the nobs are removed...looks like an Allan key but I don't seem to have one that fits?
Any help would be appreciated.

Cheers Bob.

Bob......... what you are trying to achieve is 'internal'...... and removing the knob will achieve nothing. Sounds like you need a new on/off/volume switch (pot).

An allen wrench to fit the knobs can be had at any hardware store just take your detector to make sure you get the right one as they are really small....Unfortunately as Tom says appears to be a internal problem and will have to be sent to Fisher as one of these times its not going to work at all...

If Tom has time maybe you can send it to him and he can fix it and turn it up for you.

Thanks for the replies....gang
I spoke with Tom unfortunately he does not do any repairs...so it's going to have to be sent to fisher...;(

Mine did the exact same thing. I sent it to Fisher and it came back with all the pots feeling new and tight. They also did a calibration and it seemed to be more accurate than before. I only wish I had kept the machine.

Feeling better already....thanks Fletch

Cheers Bob.
