PREPARATION
Assembly (refer to Figure 1)
Tools required: 1/2" box end wrench, 19mm wrench, 3/8" hex socket & torque wrench.
1. Three major parts should be included in the package:
(a) Hydraulic unit Assembly;
(b) Saddle Assembly;
(c) 2 pieces of base half with hardware.
2. Attach either one of the two base halves to the base of the hydraulic unit, then secure using allen head bolts and
washers provided. Apply the same procedure to the other base half. Use torque wrench to tighten to 30 lb.ft. Do
not overtighten.
3. Place the socket of the saddle assembly onto the ram piston. Tighten set screw on the socket.
Before Use
1.
Verify that the product and application are compatible, if in doubt call ATD Tools Technical Service line (636)327-
9050.
2. Before using this product, read the operator's manual completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards associated with its use.
3. Press the release valve pedal, ensure that saddle is fully lowered. Remove shipping screw and replace with
provided vent screw (shipping screw is located above the oil ller screw).
4. Remove the oil ller screw. Ensure oil level is just below the rim of oil ller hole. Reinstall the oil ller screw.
5. For air option model Atd-7431 Series A, pour a teaspoon of good quality, air tool lubricant into the air supply inlet
of the lift control valve. Connect to air supply and operate for 3 seconds to evenly distribute lubricant.
Note: This unit is equipped with the popular 1/4” NPT air coupler. When installing a different air coupler of your
choice, ensure that thread tape or compound is used when servicing connections. To ensure dependable, trouble
free operation an inline air dryer and oiler is recommended.
6. Ensure that jack rolls freely. Raise and lower the unloaded jack throughout the lifting range before putting into
service to ensure the pump operates smoothly. Replace worn or damaged parts and assemblies with ATD Tools
authorized replacement parts only.

! WARNING
• Read, understand, and follow all printed material provided with and on this product before use.
• Do not exceed rated capacity.
• Use only on hard, level surfaces.
• Adequately support the vehicle before starting repairs.
• If loaded jack must be moved, make certain that load is secured by appropriate means, is stable, is in
the lowest possible position, is moved over a smooth, hard level surface and that the lifting platform
is level.
• Use of this product is limited to removal, installation, and transportation of automotive and light
truck transmissions, transfer cases and transaxles.
• Use only adapters / accessories provided by the manufacturer of this transmission jack.
• Use only adapters / accessories whose rated capacity is greater than the rated capacity of this jack.
• Ensure the center of gravity is center loaded on the saddle.
• Never use this device as a work/repair station. Transfer the load immediately to a suitable work station.
• No alteration shall be made to this product.
• Failure to heed these markings may result in personal injury and/or property damage.
! WARNING
To avoid crushing and related injuries:
•
Never work on, under or around a load supported only by hydraulic jack.
• Be alert and sober when using this product. Do not operate under the
inuence of drugs or alcohol.
OPERATION
Follow the instruction for removal and installation of transmission, transfer case or transaxle according to the vehicle
manufacturer's service manual.
Raise saddle assembly:
Pump foot pedal or press air pump pedal (Model Atd-7431 Series A) until saddle reaches desired position. Secure
load with provided chains.
Note: DO NOT OPERATE BY AIR AND BY HAND PUMPING AT THE SAME TIME.
Ensure center gravity of load is centered on the saddle and load is stable before moving jack. An off-center
!
transmission could cause the jack to tip or ip over .
Lower saddle:
Maintain control of the rate of speed at which the load lowers at all times!
Be sure all tools and personnel are clear before
!
lowering load. Slowly engage release valve pedal!
Slowly, gently apply downward pressure to the release valve pedal.
Never use this jack as a workstation!

MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper uid can cause premature failure of the jack and the
potential for sudden and immediate loss of load. Mobil DTE 13M or equivalent recommended.
Adding oil
1. With saddle fully lowered, set jack in its upright, level position. Remove oil ller screw.
2. Fill until oil is level with the oil ller screw hole, reinstall oil ller screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With saddle fully lowered, remove oil ller screw.
2. Lay the jack on its side and drain the uid into a suitable container.
Note. Dispose of hydraulic uid in accordance with local regulations.
3. Set jack in its level position.
Lubrication
1. A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
casters and pump assemblies move freely.
2. For air option models Atd-7431 Series A: When used on a daily basis, air pump model should be internally lubricated
before each use. Use only good quality air tool lubricant. If no inline oiler is used, pour a teaspoon of air tool oil into
the inlet of the air supply inlet. Simply operate the jack using the air feature in order to fully distribute the oil.
Cleaning
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed and wipe with an oily
cloth.
Note: Never use sandpaper or abrasive material on these surfaces!
Fill until oil is level with the oil ller screw hole, reinstall oil ller screw.
Storage
When not in use, store the jack with saddle fully lowered.
