1. Apply several drops of a grade machine oil to the stem of the pump
plunger.
2. Oil the handle joints while operating the pump handle to work the oil
in.

probably never need fluid adding to the reservoir, the following
instructions should be followed in the event fluid is needed:
To refill the reservoir, place the jack in normal upright position, and
completely lower jack by opening release knob. Carefully clean dirt
and contaminants form around the fill plug and the remove the plug.
Add Mobile DTE#13 hydraulic oil to reservoir until fluid runs out the fill
plug hole. Do not use brake fluid. (Extreme care should be taken to fill
plug the fluid contaminant free and keep dirt and contaminants out of
the reservoir of the jack.) Reinstall fill plug.
To prime the model HFJ-400 actuator, in the event that it
inadvertently becomes unprimed, proceed as follows:
1. Open release valve (large red knob on top) approximately 2 full tuns.
2. Stroke handle through 2 full turns, slowly.
3. Raise handle fully up, turnover jack on left side, as viewed from rear.
Push handle "down".
4. Stand jack upright again, raise handle to up, lay over on left side
and push handle "down" again.
5. Stand jack upright, stroke handle while closing release valve and
jack should operate satisfactorily.
