SETUP
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1. Place the hydraulic power unit in an upright position. Secure the legs (index #2-4) to the cylinder (index #1-1) with the bolts (index #2-5),
washers (index #2-6) and nuts (index #1-29). Do not tighten.
2. Install the (#1-85) set screws in the bottom of the (#1-1) cylinder and tighten until snug.
3. Secure the (#2-1) swivel caster wheels and (#2-7) locking swivel caster wheels to the appropriate (#2-4) legs with the (#2-2) lock washers
and (#2-3) nuts as shown on the exploded view drawing.
4. Place the saddle assembly (index #3-32) on the stud protruding from the top of the hydraulic unit assembly, (RS7200DHU). Align the hole in
the saddle with the hole in the stud and secure with the bolt (index #3-26) and nut (#3-27).
5. Sometimes air gets trapped in the second stage hydraulic system during shipping and/or handling. Evidence of an air bound system is
a spongy feeling during the pump operation, or the ram will not rise to maximum extension, or the ram will not rise proportionate to a full
incremental pump stroke.
PURGING AIR FROM THE SECONDARY STAGE HYDRAULIC SYSTEM:
a. Turn the release valve knob in a clockwise rotation until it stops. Now turn the knob in a
counterclockwise direction two full rotations.
b. Tilt the entire jack on two caster wheels with the pump handle pointing down as shown in the
accompanying silhouette. At the same time, operate the pump handle until the loose feel of the pump is
met with some resistance.
c. Turn the release valve knob in a clockwise rotation until it stops and at the same time continue pumping
the handle while lifting the jack to its upright position.
d. Pump the jack to maximum extension. Repeat steps "a" through "c" until all air is purged from the
system.
6. The primary stage of the power unit is air activated. The air activated portion will also give the user many years of trouble free operation
if the shop air system is properly maintained. The shop air system must have an air regulator adjusted to the proper pressure. The system
must be free from dirt and moisture. Do not drop disconnected air lines on dirty shop floor or dirty environment and then reconnect to
the jack. Contaminants in the air system can cause the air valve to malfunction and the air cylinder to score. Contaminants and/or water
found in the air cylinder voids the warranty.
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.
OPERATION:
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 marked "UP" to raise the jack to maximum first
stage height. Pump the handle on the hydraulic second stage 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.
IMPORTANT: When applying a load to the jack's saddle, the jack's
air stage ram should be either lowered all the way down or extended all the way up and in its pressurized locked position. If a load is
applied to the jack's saddle when the first stage air ram is only partially raised, the jack's ram may drop suddenly.
4. Adjust the ratchet arms on the saddle so that the bent up section of the arms will fit in the mounting flange around the perimeter of the
transmission oil pan. Slowly and gently pump the jack so the connection is made and then secure the transmission to the jack's saddle
with the tie down strap 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 tie down strap is very tight when securing the transmission to the saddle and before raising or lowering the transmission.
After the transmission is secured to the jack's saddle, remove the under hoist stand.
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 valve knob on the second stage hydraulic
block in a counterclockwise direction. Make sure the jack's saddle and transmission do not hang up on any under car components, wiring,
fuel lines, etc.
IMPORTANT: Continue to lower the load until the second stage bottoms out and then depress the first stage "UP"
pedal for a second to increase air pressure before depressing the "DOWN" pedal to lower the transmission 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. IMPORTANT: Any jack found to be defective as a result of
worn parts due to lack of lubrication or air/hydraulic system contaminated with water, rust and /or foreign materials from the air
supply or other outside source is not eligible for warranty consideration.
