MAINTENANCE
MAINTAINING OIL LEVEL
Important: When adding or replacing oil,
ALWAYS use a good grade Hydraulic Jack
oil. We recommend Mobil DTE13M or
equivalent. 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 and fully
lower the saddle. (Ram will be all the way
in). Remove oil filler plug located under
cover plate (see Fig. 2).
• 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 plug and cover plate. The
jack is now ready to use.
LUBRICATION
• Add lubricating oil to all moving parts as
needed.
PREVENTING RUST
• Check ram and pump plunger (see Fig. 2)
every few months for any signs of rust or
corrosion. Clean as needed by wiping with
an oily cloth.
FIG. 2
• 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 cover plate and oil filler
plug and open release valve. Turn jack over
and drain old oil out through the oil filler
hole and into a suitable container.
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 plug and cover plate and
the jack is ready to use.
