CAUTION
BEFORE
USING
Occasionally

handling
the hydraulic oil can become
unstable
or air can get trapped in the
system,
both of which can interfere with the
jacks lifting performance.
To stabilize the oil it is recommended
to
cycle the jack a few times prior to putting
a load on it.
To release air from the hydraulic system:
° Open the release valve by turning the
jack handle counterclockwise,
but
never by more than 1/2 full turns.
• Remove the air vent valve from the
cylinder. (see Fig. 4)
° Rapidly pump jack handle through
several full strokes.
° Replace the air vent valve into the
cylinder again and jack is now ready to
use.
BEFORE
EACH
USE
Make a visual inspection
before each use
of the floor jack by checking
for abnormal
conditions,
such as cracked welds, leaks
and damaged,
loose, or missing parts.
DAMAGE
TO JACK
If you think jack has been subjected
to an
abnormal
load or shock, have it inspected
for damage
at a Sears Service
Center
