22 TON
AIR/HYDRAULIC JACK
PRODUCT DESCRIPTION
The heavy-duty OEMTOOLS 22-Ton Air/Hydraulic
Truck Service Axle Jack has a powerful air motor to
lift heavy loads with ease. The compact design easily
fits between dual tandem axles. Large rear wheels
make it easy to maneuver for quick positioning. This
jack is great for lifting axles, farm vehicles, heavy-duty
machinery and industrial construction equipment.
NEVER use for any purpose other than those uses
outlined above!
1. Verify that the product and application are
compatible, if in doubt call OEMTOOLS at
1-866-458-2472.
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. Wear appropriate safety gear, including heavy-duty
work gloves and ANSI-approved safety goggles
during use.
4. 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.
5. Do not exceed the weight capacity of the jack.
Make sure weight is evenly distributed. Be aware
of dynamic loading! Sudden load movement may
briefly create excess load causing product failure.
Exceeding the maximum capacity for this product
is dangerous and can lead to serious injury or
property damage.
6. Always evaluate your task before using this jack.
Hydraulic Truck 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. Use as intended
only.
7. Use only on a hard, level and flat surface capable
of bearing the combined weight of the Hydraulic
Truck Jack, the load being lifted, the operator and
any tools being used.
8. If you are working and the load becomes off-
balance and/or the jack begins to tip over, DO
NOT ATTEMPT TO CATCH OR LIFT THE LOAD
WHEN FALLING. SERIOUS PERSONAL INJURY
CAN RESULT! In this event, clear the area as
quickly and safely as possible in order to avoid
injury from the falling load, including getting hit
with flying fragments.
9. Before each use, inspect the general condition
of the Hydraulic Truck Jack. Check for oil leaks,
jack operation, loose components, free rotation
and pivoting of saddle adjustment components.
If a problem occurs, have the problem corrected
before further use.
TO PREVENT SERIOUS INJURY: DO NOT USE A
DAMAGED OR MALFUNCTIONING JACK
10. If in doubt about the safety of your project,
we advise you to have the work done by a
professional familiar with applicable safety
practices.
ASSEMBLY
Install the Handle Assembly according to the assembly
drawing.
OPERATION
Lifting Vehicle
Always transfer the load to appropriately rated jack
stands.
Do not work under a load which is supported only
by a jack.
Never tie, clamp or disable the lift control valve.
Only attachments and/or adapters supplied by the
manufacturer shall be used.
1. Connect an adequate air source to the air supply
inlet.
2. Before first use of this product, pour a teaspoon of
good quality air tool lubricant into the hose quick
coupler plug, then connect it to air source and
turn on the air valve and operate for 3 seconds to
evenly distribute lubricant.
Follow the vehicle manufacturer’s recommended
guidelines for lifting and the location of
recommended lift points.
3. Engage the emergency brake and chock each
unlifted wheel in both directions to prevent
inadvertent vehicle movement.
4. Close the release valve by turning the handle
wheel (31) clockwise until it is firmly closed.
5. Apply the emergency brake and use wheel chocks
to block all wheels to prevent any movement of the
vehicle being lifted.
6. Adjust the handle angle to place the jack into
position and adjust the extension screw as
needed.

7. Connect the quick coupler-male into the shop air
supply hose quick coupler-female, and then turn
on the air valve.
8. Raise the load to desired height, turn off the air
valve and immediately USE JACK STANDS with
adequate capacity to support the load.
Lowering Vehicle
Be sure all tools and personnel are clear before
lowering load.
9. When work is done, disconnect the quick coupler-
male from the air source and carefully remove the
jack stands.
10. SLOWLY and CAREFULLY lower the load by
turning the hand wheel counterclockwise in
extremely small increments, then lower the
extension screw by turning it clockwise as needed
and remove the jack.
Dangerous dynamic shock loads are created by quick
opening and closing the release valve when the load
is being lowered. The resulting overload may cause
hydraulic system failure which could cause severe
personal injury and/or property damage.
The manufacturer and/or distributor have provided
the parts list and assembly diagram in this manual
as a reference tool only. Neither the manufacturer
nor distributor makes any representation or warranty
of any kind to the buyer that he or she is qualified to
make any repairs to the product, or that he or she
is qualified to replace any parts of the product. In
fact, the manufacturer and/or distributor expressly
states that all repairs and parts replacements should
be undertaken by certified and licensed technicians,
and not by the buyer. The buyer assumes all risk and
liability arising out of his or her repairs to the original
product or replacement parts thereto, or arising out of
his or her installation of replacement parts thereto.
Note: Not all components of the Hydraulic Truck
Jack are replacement items, but are illustrated as a
convenient reference for location and position in the
assembly sequence.
Use caution when troubleshooting a malfunctioning
jack. Stay well clear of the supported load. Completely
resolve all problems before use. If the jack is
malfunctioning, have a qualified technician inspect and
repair the jack before use. After the jack is repaired:
Test it carefully without a load by raising it and
lowering it fully, checking for proper operation.
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.
1. Clean the outside of the jack with dry, clean and
soft cloth and periodically lubricate the joints,
extension screw and all moving parts with light oil
as needed.
2. When not in use, store the jack in a dry location
with ram and extension screw fully lowered.
3. Purge the hydraulic system to eliminate any air in
the system if jack efficiency drops: turn the hand
wheel 1-1/2 turns counterclockwise and remove
the oil filler plug by gently pulling, connect the air
inlet fitting to air source, turn on the air valve and
work for a while, close the hand wheel clockwise
firmly and check the hydraulic oil level, if not
adequate, top off jack reservoir with high quality
hydraulic jack oil as described above, then replace
the filler plug.
4. Check the hydraulic oil: place the jack in an upright
position, completely lower the ram and remove
the filler plug, if it is not adequate, fill with high
quality hydraulic jack oil to the lower rim of the fill
hole, purge away air from the hydraulic system as
described above, top off with more hydraulic oil,
then replace the filler plug.
5. For best performance and longest life, replace the
complete jack oil at least once per year: With the
ram fully lowered, remove the oil filler plug, lay the
jack on its side and drain the oil into a suitable
container, then fill with high quality hydraulic jack
oil as described above, reinstall the filler plug.
NOTE: Dispose of hydraulic oil in accordance with
local regulations.
