HWH recommends WD40 on their jacks
For cleaning the silver piston, NOT to lube.
HWH jacks NEVER need external spray or lubing. They are IMMERSED in ATF when retracted. As the OP found out, you can spray a lubricant to temporarily fix a sticking internal jack seal, but it is a pain to always have to do that. THE ONLY CORRECT FIX FOR A HWH JACK THAT TAKES FOREVER TO RETRACT OR STICKS IS TO REPLACE THE CYLINDER. The Internal upper seal is bad and causing the piston to bind. It will get worse and eventually, even a pry board will not get it up all the way. Until HWH realized that the upper internal seals would go bad and bind, they WERE telling people to use spray lubricants and WD 40. Once their engineers realized the problem(years ago), HWH stopped telling people to lube as they replace the offending jacks under warranty. Doug
