PRODUCT DESCRIPTION

The heavy-duty OEMTOOLS

 20-Ton Air/Hydraulic Jack 

has a powerful air motor to lift heavy loads with ease. 

The compact design easily fits between dual tandem 

axles. This jack is great for lifting axles, farm vehicles, 

heavy-duty machinery, and industrial construction 

equipment.

NEVER

 use for any purpose other than the 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. 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 only as intended. 

7.  Use only on a hard, level and flat surface capable of 

bearing the combined weight of the 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 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.
