ASSEMBLY INSTRUCTIONS
Note: This unit comes fully assembled.
IMPORTANT! BEFORE USE…
Air may become trapped in the hydraulic system
during transit. To purge air:
1. Open release valve by turning handle
counterclockwise.
2. Pump handle rapidly 4 full strokes. This will expel air
that may have entered oil passages during transit.
3. Close release valve by rotating handle clockwise
and pump handle.
4. If lift arm raises, jack is ready for use. If not, repeat
this procedure.
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, is found to be badly worn, or operates
abnormally MUST BE REMOVED FROM SERVICE until
necessary repairs are made by a manufacturer’s autho
rized 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 manufactur
-
er’s specified parts.
A list of authorized repair facilities is available from the
manufacturer.
OPERATING INSTRUCTIONS
1. To lift load, pump lever to raise saddle to
desired height to contact transmission.
2. Always position the jack so the weight of the
load is equally distributed on the saddle.
3. To tilt lifting head, manipulate the appropriate
pair of adjusting screws (there are two pairs)
located under the lifting head. When one
screw is loosened, the opposite screw should
be tightened by the same amount to maintain
a solid platform.
4. Position corner support brackets and secure the
load with chain.
5. The chain should be pulled over the load
securely and engaged into slot on the opposite
side of the saddle, then tighten wing nut.
6. To lower the jack, slowly open release valve.
Insure that load is lowered slowly.
CAUTION: Keep hands or feet away from the hinge
mechanism of the jack.
MAINTENANCE INSTRUCTIONS
All moving joints require lubrication often. Remove handle and grease the lower end of handle where it rotates
in the handle socket. Grease release valve gears. Using
a grease gun, grease the lift arm pivot shaft grease fit
ting until grease appears at the end of the shaft. Oil all
lift arm linkages, front wheels and rear casters.
OWNER/USER RESPONSIBILITY
The owner and/or user must have an understanding of
the manufacturer’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

tions and warnings shall be read to and discussed with
