My bottle jack has lost most of its oil, (initially thought the power steering was leaking) so I am going to have a go at fixing it this weekend, any advice would be appreciated. The info I have found so far is as follows, but I obviously haven�t tried it yet so I can�t confirm if it works or not. The other big problem is working out where it leaked from and fixing that. Anyone know if you can get kits?
Thanks for any help
Check Oil Level
With the jack in the upright position and the ram completely retracted, open the release valve by turning the release assembly counterclockwise. Remove the filler plug � the oil should be just up to the hole. Fill if necessary with clean hydraulic jack oil. NEVER USE MOTOR OIL OR BREAK FLUID.
Lubricate Internal Components.
With the release valve open, pump handle six full strokes to assure proper internal lubrication.
Bleed Hydraulic System.
During transit hydraulic jacks may become �air-bound�, causing spongy ram action. To bleed the hydraulic system � close the release valve by turning clockwise. Insert handle in socket and pump jack up to full height. Open release valve, invert the jack and force the ram to retract. Repeat as required.

Attacked the Jack on the weekend, worked out very well. Removed the rubber grommet on the side of the jack near the top. Then used a syringe to fill with hydraulic jack oil, (without the syringe it would have been a real mess) as per the previous instructions. Put the grommet back in and cleaned everything off. So far after 2 days no visible leaks.
Anyone have any idea why it leaked in the first place? Maybe a dry seal from lack of use? Only time will tell if this really worked, but for now it is going great.
