• Clean the outside of the jack with dry, clean and soft cloth and periodically lubricate the joints,
extension screw and all moving parts with a light oil as needed.
• When not in use, store the jack in a dry location with ram and extension screw fully lowered.
• Purge the hydraulic system to eliminate any air in the system if jack efficiency drops or jack
doesn’t work: A. If manual operation performs poorly, use the slotted end of the handle to turn
the release valve 1-1/2 turns counterclockwise and remove the oil filler plug by gently pulling, in-
sert the handle into the handle bracket and pump it 10 to 15 times, then replace the filler plug. B.
If air operation performs poorly, connect the air inlet fitting to air source, use the slotted end of
the handle to turn the release valve 1-1/2 turns counterclockwise and remove the oil filler plug by
gently pulling, turn on the air valve to let the pump work for one minute, then replace the filler
plug.
• Check the hydraulic oil: place the jack in an upright position, completely lower the ram and re-
move the filler plug, if it is not adequate, fill with high quality hydraulic jack oil to the lower rim of
the fill hole, purge away air from the hydraulic system, top off with more hydraulic oil, then re-
place the filler plug.
• For best performance and longest life, replace the complete jack oil at least once per year: With
the ram fully lowered, remove the oil filler plug, lay the jack on its side and drain the oil into a
suitable container, then fill with high quality hydraulic jack oil, reinstall the filler plug.
• NOTE: Dispose of hydraulic oil in accordance with local regulations.
• It is recommended that an annual inspection be done by qualified technicians.
