1. HWH is ADAMANT to NOT use any additive in the system
2. Under warranty, when the seals stick. HWH replaces the cylinder, NOT try to do silly things like polish the cylinder or wipe it down with something else or add an additive. ALL that does is temporarily stop the problem. It comes back in a few weeks or a month.
3. The problem is the seals have stiffened up and only a rebuild or replacement with the new style seals will fix the problem
4. If you want to know if springs are your problem
1. If they are NOT rusted and both ends taper up to the hook, your springs are OK
2. When you retract, with NO springs, you can easily push the cylinder fully up. If you suspect the springs, when it stops, manually push it up. If you cannot, then springs are not the problem. Doug
