A customer of mine has a "hydraulic" artist bench. The lever on the side does nothing to make it move up or down. It has what appears to be an air chamber (reservoir) on the underside as it has what looks like a valve stem attached to it. 1. Is this thing really "hydraulic" or is it pneumatic? 2. If pneumatic, does anyone know how much pressure belongs in that reservoir? 3. Is there any sort of repairs that a person can do to this bench mechanism to make it function again? I can send a photo privately to anyone that is familiar with this bench if that would help. John Fortiner Billings, MT -------------- next part -------------- An HTML attachment was scrubbed...
