INSPECTION AND SETUP
This is the safety alert symbol used for the INSPECTION AND SETUP section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury.
Visual inspection should be made before each use of the hydraulic wheel dolly, checking for leaking hydraulic fluid and damaged, loose or missing
parts. Any wheel dolly which appears to be damaged in any way, found to be badly worn or operated abnormally
MUST BE REMOVED FROM
SERVICE.
If the wheel dolly is accidentally subjected to an abnormal load or shock, it must be inspected by a
manufacturer's authorized repair facility immediately. It is recommended that an annual inspection of the wheel dolly 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.
Sometimes air gets trapped in the hydraulic bottle jack causing the jack ram to extend in sporadic increments instead of one smooth extension.
PURGING AIR FROM THE MANUAL PUMP SYSTEM
a. Open the release valve by turning the release valve knob in a counterclockwise direction two full turns.
b. Pump the handle ten full strokes.
c. Close the release valve by turning the release valve knob in a clockwise direction until tight.
d. Repeat steps "a" through "d" until air is purged from 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 support
procedure and all the instructions and warnings in this manual.
2. Use an under hoist stand rated greater than the weight of the engine to support the engine before unbolting the transmission from the
engine or bolting the transmission to the engine.
3. Position the transmission jack directly under the transmission. Depress the foot pedal up and down in order to raise the saddle to a height
very close to the center of balance point of the transmission oil pan but do not touch the transmission.
4. Adjust the fingers #S-4 on the saddle so that the bent up section of the fingers will fit in the mounting flange around the perimeter of
the transmission oil pan. Once the fingers are properly positioned, tighten the wing nuts that secure the fingers to the saddle. Slowly
and gently pump the jack so the connection is made, and then secure the transmission to the jack's saddle with the safety chain #S-1
provided. Sometimes it is necessary to turn the fore and aft and side to side tilt knobs so the saddle is in the proper alignment with the
transmission pan before securing the load to the saddle.
5. Make sure the safety chain #S-1 is very tight when securing the transmission to the saddle and before raising or lowering the transmission.
6. Remove the transmission from the engine according to instructions in the vehicle service manual.
7. Once the transmission has been disconnected from the engine, very slowly turn the release knob in a counterclockwise direction to make
sure the jack's saddle and transmission do not hang up on any under-car components, wiring, fuel lines, etc. Continue to lower the jack
all the way down.
8. When installing a transmission, follow the above instructions but in the applicable order and according to the vehicle
manufacturer's installation procedure.
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 Engine Stand must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter before using.
2. Lubricate moving parts, excluding the hydraulic components, monthly with a general purpose grease. Periodic lubrication should be
subject to a maintenance schedule based on frequency of use. A weekly lubrication inspection is suggested. Premature wearing of
components due to lack of or inadequate lubrication is not eligible for warranty consideration.
3. 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. Premature wearing or damage to components caused by loose or missing hardware is not eligible for
warranty consideration.
