force to the saddle for lowering.
2. Remove the inspection plate.
3. With the jack in the level position, remove the oil fill plug. Stand jack in vertical position with
handle socket down. The oil should be level with the bottom of fill hole. If not, top off. Do not
overfill. Always fill with new, clean hydraulic jack oil.
4. Replace fill plug and inspection plate.
