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 air vent valve 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
air vent valve and tool tray. The
jack is now ready to use.
LUBRICATION
• Add lubricating
oil to all moving parts as
needed.
• 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 air vent
valve and open release valve. Turn jack
over and drain old oil out through the oil
filler hole.
• Refill with new oil through the oil filler
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.
• Re-install
air vent valve and tool tray and
the jack is ready to use.
PREVENTING
RUST
Check ram and pump plunger (see Fig.
4) every few months for any signs of rust
or corrosion.
