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. Secure swivel casters (index #2-1 and #2-7) to leg caster brackets as shown in the exploded view drawing on page 4.
3. Tighten the hardware that secures the legs (index #2-4) to the cylinder (index #1-1).
4. Place the saddle assembly (index #3-31) on the stud protruding from the top of the hydraulic unit assembly, RS7200CHU. 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 when a jack will not pump full incremental pump strokes.
PURGING AIR FROM THE HYDRAULIC SYSTEM:
a. With the release valve knob (index #1-67) closed, turn the knob in a counterclockwise direction two full rotations.
b. Pump the jack handle (index #1-79) fifteen times.
c. Close the release valve knob (index #1-67) by turning it clockwise until it stops.
d. Pump the jack to maximum extension. If the condition seems better, repeat steps "a" through "d" until 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.
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 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.
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.
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 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. Continue to lower the load until the second stage bottoms out and then depress the first stage "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.
