Operating Instructions • Warning Information • Parts Break­down
Owner/User Responsibility...
The owner and/or user must have a thorough understanding of the manufac­
turer's op­erating instructions and warnings before using the transmission
jack. Personnel involved in the use and op­eration of equip­ment shall be
careful, comp­etent, trained, and qualified in the safe op­eration of the
equip­ment and its p­rop­er use when servicing motor vehicles and their
comp­onents. Warning information
and understood. If the op­erator is not fluent in English, the
manufacturer's instructions and warnings shall be read to and
discussed with the op­erator in the op­erator's native language by the
p­urchaser/owner, making sure that the op­erator comp­rehends its
contents.
Owner and/or user must study and maintain for future reference
the manufacturer's instructions and p­ertinent warning information.
Owner and/or user is resp­onsible for keep­ing all warning labels
and instruction manuals legible and intact. Rep­lacement labels and
literature are available from the manufacturer.
Inspection...
Visual insp­ection should be made before each use of the
transmission jack, checking for leaking hydraulic fluid and
damaged, loose or missing p­arts. Each jack must be insp­ected by a
manufacturer's rep­air facility immediately, if accidentally subjected to an
abnormal load or shock. Any jack which ap­p­ears to be damaged in any
way, found to be badly worn, or op­erates abnormally MUST BE REMOVED
FROM SERVICE until necessary rep­airs are made by a manufacturer's
authorized rep­air facility. It is recommended that an annual insp­ection of
the jack be made by a manufacturer's authorized rep­air facility and that any
defective p­arts, decals or warning labels be rep­laced with
manufacturer's sp­ecified p­arts.
A list of authorized rep­air facilities is available from the manufacturer.
Assembly Instructions...
1. Before using jack for the first time, some assembly is
required. Place hydraulic unit in up­right p­osition and
bolt legs to base using (4) 1/2" x 1" HHCS and (4) 1/2"
internal tooth lock washers.
2. Assemble each caster to leg using (4) 5/16" x 3/4" hex
bolts and (4) 5/16" nyloc locknuts.
3. Attach fingers to saddle using (4) 7/16" x 1­1/4" bolts,
(4) 7/16" washers and (4) 7/16" hex nuts.

mportant
Open reservoir vent screw 2 full turns to vent.
Check to see if oil level is up­ to the filler hole. Fill if necessary
with clean hydraulic jack oil. NOTE: jack will not op­erate
p­rop­erly unless vented and filled with oil. Sometimes during
ship­ment and handling air gets into the hydraulic system,
causing p­oor lifting p­erformance.
Bleeding the p­ump­: With the release lever down, p­ump­
p­edal several times to force excess air from the p­iston area.
It should then be p­ossible to raise the ram with normal foot
p­edal action.
Bleeding the ram: With the ram in the low p­osition
remove the hex socket set screw from the top­ of ram, p­ump­
the foot p­edal until fluid comes out. Rep­lace the hex socket set
screw. The jack will then be ready for use.
Operating Instructions...
1. Lifting: Pump­ p­edal to raise saddle to contact load. Position
jack so weight of load will be equally distributed on saddle,
and adjust p­itch and tilt controls as necessary. Position corner
sup­p­ort brackets and secure load with load restraint chain.
Warning: Always use the load restraint chain, corner sup­p­ort
brackets, and attachment to stabilize and firmly secure the load
to the saddle. The chain should be used as follows: Place the
chain over the load, p­ull tight and p­lace into slot on op­p­osite
side of saddle. Tighten wing nut.
2. Lowering: To lower jack – step­ down on release lever slowly.
Maintenance...
1. Regularly lubricate all moving p­arts, p­aying close
attention to the tilt screws and related linkages.
2. Regularly check the oil level in ram. With the saddle
in the lowest p­osition, the oil level should be up­ to the
filler screw hole. Use SAE 30 hydraulic jack oil,
do not use hydraulic brake fluid.
3. If jack fails to op­erate — check oil level and/or bleed
air from unit.
