®
BEFORE USING THIS JACK, READ THIS MANUAL
COMPLETELY AND THOROUGHLY, UNDERSTAND ITS
OPERATING PROCEDURES, SAFETY WARNINGS AND
MAINTENANCE REQUIREMENTS. FAILURE TO DO SO COULD
CAUSE ACCIDENTS RESULTING IN SERIOUS OR FATAL
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
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,
trained, and qualified in the safe operation of the equipment and
its proper use. Examples of hazards are dropping, tipping, or
slipping of motor vehicles or their components caused primarily by
improperly securing loads, overloading, off-centered loads, use on
other than hard level surfaces, and using equipment for a purpose
for which it was not designed.
It is the responsibility of the owner to make sure all personnel read
this manual prior to using this device. It is also the responsibility of
the device owner to keep this manual intact and in a convenient
location for all to see and read. If the manual is lost or not legible,
contact Norco Industries, Inc. for a free replacement. If the operator
is not fluent in English, the product and safety instructions shall be
read to and discussed with the operator in the operator’s native
language by the purchaser/ owner or his designee, making sure
that the operator comprehends its contents.

location and position of parts.
Before operating jack, open the black vent knob (index #10)2.
on top of the cylinder nut (index #9) by turning it all the way in a
counterclockwise direction.
The air quick disconnect configuration of your choice can be3.
installed in the threaded hole beneath the index #85 foot pedal.
Lay the power unit on a table top with the hydraulic block end4.
over the edge of the table. Install the index #58 legs onto the
bottom of index #51 hydraulic block with the bolts and washers
provided.
Install the index numbers 130 and 132 caster wheel assemblies5.
on to the ends of the legs and secure them with the nuts and
washers provided.
Install the saddle assembly (index #133) on top of the index6.
#29 ram and secure them with the index #165 bolt.
Chains, ratchet tie downs, or other acceptable means of7.
restraining and securing the transmission to the jack’s saddle must
be readily available and easily anchored to the saddle.
Make sure the system air pressure supplied to the jack is clean8.
and dry and does not exceed 100 p.s.i.

OPERATING INSTRUCTIONS
IMPORTANT: Become familiar with the pedal operation of1.
the air/hydraulic foot pump before using the jack under load.
Depressing the foot pedal end marked “Pump” raises the jack. To
raise the jack a small distance it is necesary to use incremental
taps of your foot on the foot pedal until the jack reaches the desired
height. Lowering the jack is accomplished by depressing the foot
pedal end marked “Release”. The pump is equipped with a two
speed release mechanism. Gently depressing the foot pedal end
marked “Release” lowers the jack slower than if you depress the
pedal all the way down. If you want to lower the load slower than
the slow speed release, use gentle incremental taps of your foot
on the “Release” pedal.
Lift the vehicle to the desired work height and support the2.
vehicle in accordance with the lift manufacturer’s recommended
support procedure and the warnings given in this manual.
Use an under hoist stand rated greater than the weight the3.
engine to support the engine before unbolting the transmission
from the engine.
Position the transmission jack directly under the transmission.4.
Depress the foot pedal end marked “Pump” in order to raise the
saddle to a height very close to the center of balance point of the
transmission but do not touch the transmission.
Adjust the index #149 universal saddle and index #1375.
containing angles so the flange of the transmission pan will rest on
the top edges of the containing angles. The containing angles must
then be secured to the universal saddle by tightening the index
#140 knobs. Now gently raise the saddle so the containing angles
are supporting the transmission pan flange. Fore and aft saddle
tilt adjustments are sometimes necessary to properly position the
transmission. Side to side tilt positioning may be necessary for the
same reason and can be accomplished by activating the side to
side tilt handle. IMPORTANT: Do not put excessive pressure
on either index #168 tilt handles to activate the index #166
tilt screws. Stop turning the handles when the index #162
threaded trunions or their cast brackets that contain them
come close to contacting the index #161 slave trunions or the
cast brackets that contain them.
The restraint chains should be anchored to the containing6.
angles on one side. The loose ends of the chains should be pulled
over the center of balance portion of the transmission and secured
to the two remaining containing angles. The chains should then be
tightened to secure the transmission to the saddle.
Remove the transmission from the engine according to7.
instructions in the vehicle service manual.
Once the transmission has been disconnected from the engine,8.
very slowly depress the “Release” foot pedal to make sure the
jack’s saddle and transmission do not hang up on any undercar
components, wiring, fuel lines, ect. Continue to lower the jack all
the way down.
Installation of the transmission requires the transmission jack’s9.
saddle and containing angles to cradle the transmission and the
transmission secured to the jack’s saddle with the chains.
An under hoist stand rated greater than the weight of the engine10.
should be supporting the engine before transmission installation.
Raise the transmission slowly and at the same time position the11.
jack so the transmission aligns with the engine. Do not remove the
restraints, nor lower the jack, nor remove the under hoist stand
until the transmission is secured to the engine and the engine and
all corresponding components are prevented from falling.

be exposed to inclement weather, corrosive vapors, abrasive dust,
or any other harmful elements. The jack must be cleaned of water,
snow, sand, or grit before using.
The jack must be lubricated periodically in order to prevent2.
premature wearing of parts. A general purpose grease must be
applied to caster wheels, front axle wheels, elevator arm, handle
base pivot bolts, release mechanism and all other bearing
surfaces. See the exploded view parts drawing for the location of
the above mentioned parts. Failure to maintain proper lubrication
voids warranty.
It should not be necessary to refill or top off the reservoir with3.
hydraulic fluid unless there is an external leak. An external leak requires
immediate repair which must be performed in a dirt-free environment
by qualified hydraulic repair personnel who are familiar with this
equipment. Norco Authorized Service Centers are recommended
IMPORTANT: In order to prevent seal damage and jack failure,
never use alcohol, hydraulic brake fluid, or transmission oil
in the jack.
Every jack owner is responsible for keeping the jack label4.
clean and readable. Use a mild soap solution to wash external
surfaces of the jack but not any moving hydraulic components.
Contact Norco Industries for a replacement label if your jack’s label
is unreadable.
Inspect the jack before each use. Do not use the jack if any5.
component is cracked, broken, bent, shows sign of damage, or
leaks hydraulic fluid. Do not use the jack if it has loose or missing
hardware or components, or is modified in any way. Take corrective
action before using the jack again.
Do not attempt to make any hydraulic repairs unless you are a6.
qualified hydraulic repair person that is familiar with this equipment.
