TJHAIR1000 1/2 Ton Air/Hydraulic Telescopic Transmission Jack
INSPECTION
Visual inspection should be made before each use of the 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 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
authorized 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 manufacturer’s
specified parts. A list of authorized repair facilities is available from the manufacturer.
SETUP
Please refer to the exploded view drawing on page 5 in this manual in order to identify parts:
1. Place the hydraulic power unit horizontally on a bench. Secure the legs (#2-4) in the receivers in the bottom of
the cylinder (#1-1A) with the bolts (#2-5), washers (#2-6) and nuts (#1-29). Do not tighten.
2. Tighten the set screw at the bottom of each leg receiver so the legs are firmly seated in the receivers.
3. Secure swivel casters (#2-1 and #2-7) to leg caster brackets as shown in the exploded view drawing on page 5
and place the jack upright on the floor.
4. Tighten the hardware that secures the legs (#2-4) to the cylinder (#1-1A).
5. Place the saddle assembly on the stud protruding from the top of the hydraulic unit assembly, (RS1000AHUBR).
Align the hole in the saddle with the hole in the stud and secure with the bolt (#3-26) and nut (#3-27).
6. 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.
7. 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.
IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended
lifting surfaces.
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
