To Add Oil: With saddle fully lowered and ram depressed,
set jack in an upright position and remove oil filler plug.
Fill until oil is level with filler plug hole.
To Change Oil: For best performance and longest life,
replace the complete oil supply at least once a year.
To drain the oil, remove the filler plug. Lay the jack on
its side and allow the oil to run out into suitable drain
pan. The oil will run slowly because air must enter as oil
drains out. Be Careful to prevent dirt or foreign matter
from entering the system. Replace with proper oil.

oil. Avoid mixing types of oil. do not use brake
fluid, transmission fluid, alcohol, glycerin, deter-
gent motor oil, or dirty oil. Improper fluid can
cause serious internal damage to the jack, render-
ing it inoperative.
