ImPoRtANt: Use only a good grade hydraulic jack oil.
Avoid mixing types of oil. Do not use brake fluid, alcohol,
glycerin, detergent motor oil, or dirty oil. Improper fluid
can cause serious internal damage to the jack, rendering
it inoperative.
To add oil: With saddle fully lowered and jack on level
ground, remove filler plug (see Fig. 1). Oil should be
filled to level of oil filler plug hole. If low, add oil as
needed.
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.
