Inquiry (采购产品): lubrication I have a Linak Electric lifting column on a piece of medical equipment in my office Model#281000-01402400, that has begun to stick. What is the appropriate type of lubrication to use on this device and where should the lubrication be applied? **** Hidden Message ***** Gary McClinton 75964 Company: Dr. McClinton E-mail: gwmcclinton@yahoo.com **** Hidden Message ***** gwmcclinton@yahoo.com
