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
the use and operation of equipment who are careful, competent,

Support the engine with a stand before unbolting the
transmission from the engine.
•
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 chains and corresponding chain hardware are provided
in order to secure the transmission to the saddle assembly and
containing angles. One end of each chain should be anchored to
a containing angle. The restraint system (chain, chain hardware,
and containing angles) may be adjusted according to the specific
transmission configuration.
3.
Sometimes air gets trapped in the jack during shipment. An
air bound hydraulic system feels spongy when pumped and
sometimes the jack will not pump full incremental strokes.
