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 plug located
under tool tray (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 plug and tool tray. 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.
4) every few months for any signs of rust
or corrosion. Clean as needed by wiping
with an oily cloth.
PLUNGER DOWN

MAINTENANCE

• When not in use, ALWAYS store jack with
saddle and pump plunger 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 tool tray and oil filler
plug 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 plug and tool tray and
the jack is ready to use.
