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 from the reservoir
(see Fig. 4 & 5).
• 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. The jack is now
ready to use.
LUBRICATION
• Add lubricating
oil to all moving
parts as
needed.
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.
PREVENTING
RUST
• Check
ram and pump
plunger
(Fig.
5)
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.
