6718 link arms drop over night

[dandd]

The link arms on the old 6718 drop completely over night. Dont know what the reason is, guessing its a seal on a return valve or something? Wonder if anyone has any experience of the issue and if its an easy fix

Cheers

You may start by putting new seals in the lift cylinder under the lift cover, you can check by putting something heavy on the lift put it up near the top and turn off the engine and see how long it stays up.
