PRODUCT DESCRIPTION
ATD Tools Air Hydraulic Bottle Jacks are designed to lift 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 to each jack operated. A minimum of 150 psi air pressure is required
to raise rated capacity load.
WARNING: Never use a hydraulic jack as a stand alone support device. After lifting, immediately support the
!
vehicle with appropriately rated jack stands. Never place any portion of your body under the vehicle when lifting
or lowering.
PREPARATION
Before Use
1. 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.
2. Verify that the product and application are compatible, if in doubt call Technical Service (816) 891-6390.
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 saddle fully lowered, and release valve closed, pump the operating handle. If ram responds immediately,
jack is ready for use. If jack does not respond, follow Bleeding/Venting Trapped Air procedure below.
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.
NOTICE: 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 in-line air dryer and oiler is recommended.
7. Check that the pump operates smoothly and that the extension screw adjusts up/down easily before putting into
service. Replace worn or damaged parts and assemblies with genuine ATD Tools 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
air vent screw/ller plug. 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 air vent screw/ller plug.

OPERATION
Raising the Ram Plunger
1. Assemble handle, ensure that spring clips align with slots.
2. Place vehicle in park, with emergency brake on and wheels securely chocked to prevent inadvertent vehicle
movement.
3. Close release valve by turning handle clockwise until rm resistance is felt.
NOTICE: Always use the provided pump handle. The handle furnished 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, discontinue use of the jack until a factory replacement handle can be acquired.
4. Verify lift point, center jack saddle under lift point.
WARNING: Never wire, clamp or otherwise enable the lift control valve to function by other than operator's
!
hand. Do not attempt operating pump by air and by handle simultaneously.
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.
6. Immediately transfer the load to a pair of appropriately rated jack stands.
NOTICE: Do not use extensions on air hose or operating handle.
Lowering
WARNING: Clear all tools and personnel before lowering load. Open release valve slowly. The further handle
!
is turned counter-clockwise, the faster the load will descend. Maintain control of the load at all times.
1. Raise load high enough to clear the jack stands, then carefully remove jack stands.
2. Slowly turn the handle counter-clockwise, but no more than 1/2 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 using the functioning jack.
3. After removing jack from under the load, push ram and handle sleeve down to reduce exposure to rust and
contamination.
MAINTENANCE
NOTICE: Use premium quality 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.
Adding oil
1. With ram plunger fully lowered and pump piston fully depressed, set jack in its upright, level position. Remove air
vent screw/ller plug.
2. Fill with oil until just below the rim of the air vent screw/ller plug hole. Reinstall the air vent screw/ller plug.
Changing oil
For best performance and longest life, completely replace the uid supply at least once per year.
1. With ram plunger fully lowered and pump piston fully depressed, remove the air vent screw/ller plug.
2. Lay the jack on its side and drain the uid into a suitable container.
NOTICE: Dispose of hydraulic oil in accordance with local environmental regulations.
3. Fill with oil until just below the rim of the air vent screw/ller plug hole. Reinstall the air vent screw/ller plug.
4
Lubrication
1. A periodic coating of light lubricating oil to pivot points, axles and hinges will help to prevent rust and assure that
pump assemblies move freely.
2. When used on a daily basis, air pump should be internally lubricated before each use. Use premium quality air
tool lubricant. If no inline oiler is used, pour a teaspoon of air tool oil into the inlet of the air control valve. Simply
operate the jack using the air feature in order to fully distribute the oil.
Cleaning
Periodically check the pump piston and ram plunger for signs of rust or corrosion. Clean as needed and wipe with
an oily cloth.
NOTICE: Do not use sandpaper or abrasive material on ram and pump piston surfaces.
Storage
When not in use, store the jack with pump piston and ram plunger fully retracted and air supply disconnected.
