Sorry, not too sure what you really mean in the claim form as attached. Do you mean that the seals had been replaced and now it works fine? If so, please indicate on the form on your purchased parts, invoice number for processing.
There is a way to test if the seal of the cylinders are leaking.
Raise each cylinder till it stops. Release the return hose from the cylinder and operate raise again. If there is oil leaking under pressure from the hose, then the seal is not good.
It is unusual to have both cylinder seals leaking at the same time.
