PRODUCT DESCRIPTION
Air Actuated Hydraulic Bottle Jacks are designed to lift, not support, rated capacity loads consisting of one end of
a vehicle. Immediately after lifting, the load must be supported by a pair of appropriately rated jack stands. Ensure
that air source can dedicate 7.8 CFM @ 110-175 psi. A minimum of 150 psi air pressure is required to raise rated
capacity load.
Never use hydraulic jack as a stand alone device. After lifting, immediately support the lifted load
!
with a pair of appropriately rated jack stands. Never place any portion of your body under a load
when lifting or lowering the load.

materials provided with/on this product before use.
• Do not exceed rated capacity.
• This is a lifting device only!
• Immediately after lifting, support the load with
a pair of appropriately rated jack stands.
• Use only on hard, level surface.
• Do not use adapters or accessories that are not
provided initially.
• Lift only on areas of the vehicle as specied by
the vehicle manufacturer.
• Never wire, clamp or otherwise disable the lift
control valve to function by other than operator's
hand.
• No alterations shall be made to this product.
• Failure to heed these markings may result in
personal injury and/or property damage.
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 nor
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 inuence of drugs or alcohol.

PREPARATION
Before Use
1.
Verify that the product and application are compatible, if in doubt call ATD Technical Service (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. Assemble handle, ensure spring clips align with slots.
4. To familiarize yourself with basic operation, use the notched end of provided handle to engage and turn the release
valve:
a. Clockwise until rm resistance is felt to further turning. This is the ‘CLOSED’ release valve position used to
raise the ram plunger.
b. Counter-clockwise, but no more than 1 turn from the closed position. This is the ‘OPEN’ release valve
position used to lower the ram plunger.
5. With ram fully retracted, locate and remove the oil ller plug/screw. Insert the handle into the handle sleeve, then
pump 6 to 8 strokes. Ensure the oil level is just below the oil ller hole. Reinstall the oil ller plug/screw.
6. Pour a teaspoon of good quality, air tool lubricant into the air supply inlet of the lift control valve. Connect to air
supply and squeeze lift control valve for 3 seconds to evenly distribute lubricant.
7. This product 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.
8. Check that the pump operates smoothly and that the extension screw will thread up/down easily before putting
into service. Replace worn or damaged parts and assemblies with ATD authorized replacement parts only.
Bleeding / Venting Trapped Air
With the release valve in the OPEN position (4b above) and with ram plunger fully lowered, locate and remove the
oil ller plug/screw. Insert the handle into the handle sleeve; then pump 6 to 8 full strokes. This will help release any
pressurized air which may be trapped within the reservoir. Oil level should be even with the bottom of the oil ller
hole. Reinstall the oil ller plug/screw.
Use only handle provided by jack manufacturer. The handle provided with this jack will safely engage the
!
release valve and operate the handle sleeve. If handle is worn, operates abnormally, or will not positively
engage the release valve, STOP, discontinue use of the jack until a factory replacement handle can be acquired.
Paint contains lead! DO NOT sand or grind painted surface!

OPERATION
Raising the Ram Plunger
1. Assemble handle, ensure that spring clips align with slots.
2. Place vehicle in the park, with emergency brake on and wheel securely chocked to prevent inadvertent vehicle
movement.
3. Locate and close release valve by turning handle clockwise until rm resistance is felt to further thread
engagement.
4. Verify lift point, center jack saddle under lift point.
5. Squeeze the lift control valve or insert handle into handle sleeve and pump to contact lift point. To lift, continue
pumping until load reaches desired height. DO NOT OPERATE BY AIR AND BY HAND PUMPING AT THE
SAME TIME.
6. Immediately transfer the lifted load to a pair of appropriately rated jack stands.
Do not use an extender on the air hose or the operating handle.
!
Lowering
Make certain that all personnel are clear of the load before lowering. Control the rate of descent of the
!
load at all times. The more you open the release valve, the faster the load descends.
1. Raise load high enough to clear the jack stands, then carefully remove jack stands (always used in pairs).
2. Slowly turn the handle counter-clockwise, but no more than 1 turn. If the load fails to lower:
a. Use another jack to raise the vehicle high enough to reinstall jack stands.
b. Remove the affected jack and then the stands.
c. Lower the load by turning the release valve counter-clockwise, but no more than 1 turn.
3. After removing jack from under the load, push ram and handle sleeve down to reduce exposure to rust and
contamination.
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. We recommend Mobil DTE 13M or equivalent.
Adding oil
1. With ram plunger fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove oil
ller plug/screw.
2. Fill with oil until just below the rim of the oil ller screw hole. Reinstall the oil ller plug/screw.
Changing oil
For best performance and longest life, replace the complete uid supply at least once per year.
1. With ram plunger fully lowered and pump piston fully depressed, remove the oil ller plug/screw.
2. Lay the jack on its side and drain the uid into a suitable container.
Note: Dispose of hydraulic oil in accordance with local regulations.
3. Fill with oil until just below the rim of the oil ller hole. Reinstall the oil ller plug/screw.
Lubrication
1. A periodic coating of light lubricating oil to pivot points will help to prevent rust and assure that pump assemblies
move freely.
2. Air pump should be internally lubricated before each use. Use good quality air tool lubricant. If no inline oiler
is used, pour a teaspoon of air tool oil into the air control valve inlet. Operate the jack with air pressure to fully
distribute the oil inside the air motor.
Cleaning
Periodically check the pump piston and ram for signs of rust/corrosion. Clean as needed and wipe with oily cloth.
Note: Never use sandpaper or abrasive material on these surfaces!
Storage
When not in use, store the jack with pump piston and ram plunger fully retracted and air supply disconnected.
