The top sliding head is getting stiffer and stiffer.
I believe its a chain drive and although I managed to locate the drain plug for the top chamber I cannot find any way to add lubricant ?
The outer two nuts are clamps , the middle one is used to move the sliding head.
Does anyone have any ideas ?
