Hi all,

I know there aren't too many of these left in use in the UK, but here we have quite a few! I have a small pile of them with eithe occlusion alarm or 'syringe force' type alarms. This suggests plunger calibration issues perhaps?

Does anyone have any hints or tricks re mechanical calibration of these? The service doc shows special dial gauges etc, but I do not have any access to those manufacturers special tools!

The sad thing is, I will probably have to bin these drivers if I can't sort them out, and I think really there isn't too much wrong with them!

Thanks.
