MAINTENANCE
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. We recommend
Mobil DTE13M or equivalent.
ADDING OIL
• Position the jack on level ground and
fully lower the saddle. (Ram will be all the
way in). Remove oil filler screw from the
reservoir (see Fig. 3 & 4).
• Oil should be filled to the level of about
3/16” above the inner cylinder as seen
from the oil filler hole. If low, add oil as
needed.
• Re-install oil filler screw. The jack is now
ready to use.
LUBRICATION
• Add lubricating oil to all moving parts as
needed.
PREVENTING RUST
• Check ram and pump piston (see Fig. 4)
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 lowered all the way down.

ANNUAL INSPECTION
To ensure that it is in optimum condition,
annual inspection of the jack at a Sears
Service Center is recommended.
REPLACING OIL
• To drain oil, remove oil filler screw and open
release valve. Turn jack over and drain old
oil out through the oil filler hole.
Note: Dispose of hydraulic oil in accordance
with local regulations.
• Refill with new oil through the oil filler hole.
DO NOT allow dirt or 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.
• Re-install oil filler screw and the jack is
ready to use.
