OWNER'S MANUAL
INSPECTION AND SETUP
This is the safety alert symbol used for the SETUP INSTRUCTIONS section of this manual to alert you to potential personal injury
hazards. Obey all instructions to avoid possible injury or death.
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Secure the fingers (#44) to the finger bases (#41) with the hardware (#27 and #35) provided.
2. Loosely assemble the finger bases (#41) to the saddle plate (#52) as shown in the exploded view drawing.
3. Secure one end of the chain (#51) to the saddle plate (#52). Connect the bolt (#34) to the saddle plate (#52) with the hardware (#27 and
#35) provided. Slide the hook (#32) through the bolt (#34) and secure the hook with the wing nut (#33).
4. Air may get trapped in the hydraulic system during freight and handling.
PURGING AIR FROM THE HYDRAULIC SYSTEM:
a. Rotate the knob at the top of the hydraulic block in a clockwise direction until tight.
Now turn it in a counterclockwise direction two full turns.
b. Activate the hand pump about 15 times.
c. Rotate the release valve knob at the top of the hydraulic block in a clockwise direction until tight.
d. Activate the hand pump until the lift arm is raised to maximum height. You should experience a full pump stroke with each
incremental pump.
e. Repeat steps "a" through "d" until all air is purged from the system.
OPERATING INSTRUCTIONS
This is the safety alert symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
1. Lift the vehicle to the desired work height, and support the vehicle in accordance with the lift manufacturer's recommended lifting and
support procedures.
2. Position the transmission jack directly under the transmission. Turn the release valve knob all the way in a clockwise direction until it stops.
Pump the handle, and the saddle assembly will start to rise. Raise the saddle to a height very close to the center of balance point of the
transmission, but do not touch the transmission.
3. Loosen the four bolts that secure the four fingers to the saddle. The fingers can be adjusted in and out to help position the transmission
on the saddle. Now gently raise the saddle so it supports the transmission. Adjust the four fingers in position against the transmission, and
tighten the bolts that secure the fingers to the saddle. Fore and aft saddle tilt adjustments are sometimes necessary to properly position
the transmission on the saddle. Side to side tilt positioning may be necessary for the same reason and can be accomplished by activating
the side to side tilt knob.
4. The chain should be pulled over the center of balance portion of the transmission and secured on the chain hook. Rotate the
wing nut to take up the slack in the chain and secure the transmission to the saddle.
5. Remove the transmission from the engine according to instructions in the vehicle service manual.
6. Once the transmission has been disconnected from the engine, very slowly turn the jack's release valve knob in a counterclockwise
direction to make sure the jack's saddle and transmission do not hang up on any under vehicle components, wiring, fuel lines, etc.
Continue to lower the jack all the way down.
7. Remember to secure the transmission to the saddle before installing, and follow the vehicle manufacturer's installation instructions.

PREVENTATIVE MAINTENANCE

This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential personal
injury hazards. Obey all instructions to avoid possible injury or death.
1. Always store the jack in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive dust, or any
other harmful elements. The jack must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2. The jack must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be applied to
all zerk grease fittings, caster wheels, elevator arm, handle base pivot bolts, release mechanism and all other bearing surfaces. Jacks
found to be defective due to worn parts resulting from inadequate or no lubrication are not eligible for warranty consideration.
3. It should not be necessary to refill or top off the reservoir with 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.
IMPORTANT: In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid or transmission oil in the jack. Use
Chevron Hydraulic Oil AW IS0 32 or its equivalent Unocal Unax AW150.
4. Every jack owner is responsible for keeping the jack labels clean and readable. Use a mild soap solution to wash external surfaces of
the jack but not any moving hydraulic components. Contact Sunex for a replacement label if your jack's label is unreadable.
5. Inspect the jack before each use. Do not use the jack if any 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.
6. Do not attempt to make any hydraulic repairs unless you are a qualified hydraulic repair person that is familiar with this equipment.
Repairs must be performed by an authorized service center.
