The use of portable automotive lifting devices is subject to certain
hazards that cannot be prevented by mechanical means, but
only by the exercise of intelligence, care, and common sense. It
is therefore essential to have owners and personnel involved in
theuse and operation of equipment who are careful, competent,
trained, and qualified in the safe operation of the equipment and
its proper use. Examples of hazards are dropping, tipping, or

• Adequately support the vehicle before starting repairs. Consult
the vehicle manufacturer for the recommended procedure
for removing and installing transmissions with a floor model
transmission jack.
• Once the vehicle is supported, make sure there is enough
clearance to maneuver the jack and transmission underneath
the vehicle.
• Inspect the jack before each use. Do not use the jack if it is
damaged, altered, modified, in poor condition, leaking hydraulic
fluid or unstable due to loose or missing hardware. Take
corrective action before using the jack.
• Do not use jack beyond its rated capacity. Do not lift or support
the vehicle with this jack.
1. Refer to the exploded view parts drawing for identification,
location and position of parts.
2. The chain and hook are provided in order to secure the
transmission to the saddle assembly. The end of the chain should
be anchored to the side of the saddle. The restraint system (chain
and hook assembly) may be adjusted according to the specific
transmission configuration.
3. Sometimes air gets trapped in the jack's hydraulic system
during shipment. An air bound hydraulic system feels spongy when
pumped and sometimes the jack will not pump full incremental
strokes.
