2. Turn the jack upside down and drain the old oil out through the hole of the oil
chamber (Fig. 2).
3. Fill the jack with new oil through the hole of the oil chamber.
Do not allow any dirt or other foreign material to enter the hydraulic system when
re-filling.
After Re-filling the jack oil, remove any air from the hydraulic system (please refer
to caution on page 3 before use)
LUBRICATION:
Lubricate all pivoting and moving points with lubricating oil prior to initial use and
after every 20 lifting/lowering cycles or 3 months (whichever occurs first)
RUST PREVENTION & STORAGE:
1. Check jack every few months for any signs of rust or corrosion. Clean as needed
by wiping with an oily cloth.
2. When not in use, always store jack with wheels on horizontal surface and with
lifting arm lowered all the way.
