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.
