MAINTENANCE
MAINTAINING OIL LEVEL
Important:
Use only a good grade hydraulic
jack oil. Avoid mixing different types of fluid
and Never use brake fluid, turbine oil,
transmission fluid, motor oil or glycerin.
Improper fluid can cause failure of the jack
and the potential for sudden and immediate
loss of load. We recommend Mobil DTE13M
or equivalent.
ADDING OIL
• Position the jack on level ground and fully
lower the saddle. (Ram is 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
For best performance and longest life,
replace the complete fluid supply at least
once per year.
• To drain oil, with saddle fully lowered,
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.
N o t e : D i s p o s e o f h y d r a u l i c o i l i n
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.
