PRODUCT DESCRIPTION
Hydraulic Axle Jacks are designed to lift, but not support, rated capacity partial vehicle loads consisting of one end of a vehicle. Immediately after lifting, support loads with a pair of appropriately rated jack stands.
PREPARATION
Reference replacement parts pages 6 and 7 for parts location and assembly sequence. Assemble, align and insert the handle assembly and handle position bar into the handle sleeve, then tighten the bolt on handle sleeve to prevent accidental removal of handle while in use.
ASSEMBLY
- Install the handle assembly according to the assembly drawings below. Use bolt (#54) to lock handle-1 (#52) and handle-2 (#55); pass the slotted pin (#49) through the hole on handle-1 (#52) and screw the slotted pin (#49) with tie rod (#56), tighten the nut (#53) then put the R-pin (#71) through the hole in the slotted pin (#47), make sure that the R-pin is over the ear of handle-1.
- Use bolt (#73) to lock the handle and frame body; connect the PU tube with the joint by same color.
- Assemble the extensions to the handle according to the following drawings:
STEP 1
Route air hoses though the handle tubes as shown below:
STEP 2
Note hose colors and numbers and make sure hoses are routed as shown below:
STEP 3
Connect hoses as shown below:
Hose 1 should be inserted into Connector 1
Hose 2 should be inserted into Connector 2
Before Use
-
Verify that the product and application are compatible, if in doubt call ATD Tools, Inc. Technical Service at 636-327-9050.
-
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.
-
To familiarize yourself with basic operation, locate the air lever (#78) on the cross valve on top of the handle:
a. Rotate the air lever to the right, which is the “closed” position used to lift the load.
b. Rotate the air lever to the left, which is the “open” position used to lower the load.
c. Rotate the air lever to the middle, which is the “stop” position used to hold the load. -
With ram fully lowered, remove the oil filler plug. Check oil level. Proper oil level should be just below the rim of the opening. Reinstall the oil filler plug.
-
Pour a teaspoon of good quality air tool lubricant into the air supply inlet of the lift control valve. Connect to air supply, then squeeze the lift control valve for 3 seconds to evenly distribute lubricant.
NOTICE: These models are equipped with 1/4″ NPT air couplers. If installing a different air coupler, ensure thread tape or compound is used on connections. To ensure dependable, trouble free operation an inline air dryer and oiler is recommended. -
Ensure that jack rolls freely. Raise and lower the unloaded ram throughout the lifting range before putting into service to ensure the jack operates smoothly. Replace worn or damaged parts and assemblies with ATD Tools, Inc. authorized replacement parts only.
Bleeding/Venting Trapped Air
- Open oil filler plug.
- Rotate the air lever to the right slightly to activate the air motor for slow pumping.
- Rotate the air lever to the left slightly to activate the air motor for slow pumping.
- Repeat steps 2 and 3 several times.
- Rotate air lever to the left until the ram is fully retracted.
- Check oil level and reinstall oil filler plug.

WARNING
- Study, understand, and follow all instructions before operating this device.
- Do not exceed rated capacity.
- Use only on hard, level surface.
- Lifting device only. Immediately after lifting, support the vehicle with appropriate means.
- Do not move or dolly the vehicle while on the jack.
- Lift only on areas of the vehicle as specified by the vehicle manufacturer.
- No alterations 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.
- Always use adequately rated jack stands.
- Chock each unlifted tire in both directions.
- Do not use this device to lift, level, lower, support or move a house, mobile home, travel trailer, camper or any building structure.
- Be alert and sober when using this product. Do not operate under the influence of drugs or alcohol.
**** The wheels provided with this jack are for positioning the jack under a load ONLY! The wheels are not load wheels. Do not try to dolly or move the vehicle with the jack!
OPERATION
Lifting
Note: The jack is equipped with handle position lock. To adjust the handle, release lock device by pulling the lever up, lever is spring loaded and will lock into desired position. Ensure lever locking mechanism is fully engaged before lifting.
- Connect adequate air source to the air supply inlet.
- Follow the vehicle manufacturer’s recommended guidelines for lifting. Engage the emergency brake and chock each unlined wheel in both directions to prevent inadvertent vehicle movement.
- Center jack saddle under lift point, then squeeze the lift control valve until saddle contacts the lift point. To lift, continue squeezing the lift control valve until load reaches desired height. Simply release your grip on the lift control valve to end lift event.
- Transfer the load immediately to appropriately rated jack stands.
WARNING: Only attachments and/or adapters supplied by the manufacturer should be used. Lift only on area of the vehicle as specified by the vehicle manufacturer.
WARNING: NEVER use hydraulic jack as a stand alone device! ALWAYS transfer the lifted load IMMEDIATELY to a pair of appropriately rated jack stands. Use one pair of jack stands per vehicle. Rated capacity is per pair only! Do not exceed rated capacity.
Lowering
WARNING: Be sure all tools and personnel are clear before lowering load.
- Raise load high enough to clear the jack stands.
- Remove jack stands carefully (always used in pairs).
- Rotate the cross valve air lever to the left to lower the load. Your ATD-7328A is equipped with a speed limiting valve so the lowering speed is controlled automatically.
- After removing jack from under the vehicle, fully retract the jack to reduce ram exposure to rust and contamination.
MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid mixing different types of fluid and NEVER use brake fluid, turbine oil, transmission fluid, motor oil or glycerin. Improper fluid can cause premature failure of the jack and the potential for sudden and immediate loss of load. We recommend premium hydraulic oil or equivalent.
Adding/ Changing Oil
For best performance and longest life, replace the complete fluid supply at
least once per year.
-
With saddle fully lowered remove cover plate, then oil filler plug.
-
Lay jack on its side and drain fluid into a suitable container.
NOTICE: Dispose of hydraulic fluid in accordance with local environmental regulations. -
Set jack in its upright, level position.
-
Fill with oil. Proper oil level is just below the rim of the opening. Reinstall the oil filler plug.
-
Perform BleedingNenting Trapped Air procedure.
Lubrication
A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that wheels move freely and the pump functions smoothly. To help ensure trouble free operation, an inline air dryer and oiler is recommended.
Cleaning
Periodically check the ram for signs of rust or corrosion. Clean as needed and
wipe with an oily cloth. Note: Never use sandpaper or abrasive material on ram
surfaces!
Storage
When not in use, store the jack with saddle fully lowered.
