STORAGE
HOW TO STORE YOUR JACK
This jack is designed for compact and convenient storage (see Fig. 5).
• Insert the rubber handle holder onto the top nut.
• Depress the spring lock to separate the handle pieces, and insert them into the handle
holder.
MAINTAINING OIL LEVEL
Important: When adding or replacing oil,
ALWAYS use a good grade Hydraulic Jack
oil. DO NOT use Hydraulic Brake Fluid,
Alcohol. Glycerine, Detergent, Motor Oil or
dirty oil. Use of an improper fluid can cause
serious internal damage to your jack.
ADDING OIL
• Position the jack on level ground in an
upright (vertical) position and fully lower the
saddle.
• Remove oil filler plug (see Fig. 3).
• Oil should be filled to the level of the oil
filler plug hole. If low, add oil as needed.
REPLACING OIL
• To drain oil, remove oil filler plug and open
release valve (see Fig. 3).
• Turn jack on its side and drain old oil out
through the oil filler plug hole.
• Refill with new oil through the oil filler plug
hole. DO NOT allow dirt or other foreign
material to enter the hydraulic system when
filling.
• After refilling, remove any air from the
hydraulic system by opening the release
valve and rapidly pumping the jack handle
several times.
• Replace the oil filler plug.
LUBRICATION
• Add lubricating oil to all moving parts as
needed.
PREVENTING RUST
• Check ram and pump plunger (see Fig. 3)
every few months for any signs of rust or
corrosion. Clean as needed by wiping with
an oily cloth.
• When not in use, ALWAYS store jack with
saddle and pump plunger lowered all the
way down.
