There really is no maintenance. It all depends on how the OEM looped the cables when installing. I have one of these from years ago and used it on the old Motorhome Heater control cables. I guess to could use it on the Valve cables. This tool allows you to inject WD 40 or similiar thru the interior of the cable where it slides. Doug
The description of the product you provided a link to does not say how it is used. If access to the entire length of the cable is required, then it won't work for me where I have zero ready access to the cable. I've squirted WD-40 where the cable enters the outer sheath, but that doesn't help. Also, only one of three cables is hard to operate and it has been this way since new 5 years ago, so maybe it is not a lubrication issue.
What you have to do is, access the actual Valve. Remove the Cable from the valve and then install this tool and spray the lube. What the tool does is clamp OVER the outer sheath and the tool then seals when you tighten it. YOu then insert the plastic spray tube from the WD 40 into the rubber grommet hole of that tool and spray until it comes out the other end of the cable. You cannot do this from the Handle end of the Valve system. Doug
