MAINTENANCE
1. Clean the outside of the jack with a dry, clean, soft cloth and periodically lubricate the joints, extension
screw and all moving parts with a light oil as needed.
2. When not in use, store the jack in a dry location with ram and extension screw fully lowered.
3. 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, insert 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.
4. Check the hydraulic oil: place the jack in an upright position, completely lower the ram and remove 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 replace the filler plug.
5. 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.
NOTE:
It is recommended that an annual inspection be done by qualified technicians.
