MAINTENANCE
INSTRUCTIONS:
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.
3. Although the hydraulic unit on the
FJ4B
is a sealed unit and will
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.
