A PRO EAGLE JACK IS ONE OF THE MOST IMPORTANT RECOVERY TOOLS YOU OWN—AND IT’S BUILT TO PERFORM UNDER PRESSURE.

To keep it that way, the two most important things you can do are prime the pump and maintain proper fluid levels.
Our jacks are made to live in rough conditions, so we use oversized breathers that resist clogging—but over time, this also allows air to enter the pump system, especially after travel or storage.
If your jack isn’t lifting properly, don’t assume it’s broken. Most issues come down to air pockets or low fluid—both easy fixes with a little regular attention. Below, you’ll find the exact steps to get your jack back in working shape, just like it should be.

HOW TO PRIME YOUR JACK

If your jack will not lift correctly, it has most likely lost prime. We use larger-than-normal breathers so they don’t get clogged with dirt. This also allows for the pressure inside the jack to equalize with outside pressure if not used frequently.
TO FIX THIS:
1.Turn the handle counterclockwise 1–2 turns.
2.Pump the handle 10-15 times.

This pushes out the trapped air and should correct the usability issue. This procedure is recommended when the jack hasn’t been used in a couple of days or if it was subject to vibration after traveling in a vehicle. Air bubbles in the fluid will create the same “doesn’t want to lift weight” feel to the user.

HOW TO CHECK THE FLUID LEVEL

👉🏼 For 1.5 ton and 3 ton jacks:
 There is a threaded or rubber plug on the main cylinder/ram of the jack. You’ll need to remove the top plate to access this plug. Add jack oil (any jack oil from a local parts store will work) until the cylinder is ¾ full or until the jack works correctly. Do not overfill or the jack may not lower correctly. If the jack is operated and lowered, it will push out excess fluid from the reservoir if overfilled.
👉🏼 For the 2 ton jack:
There are three caps on the top of the pump. Two are centered, and one is offset. The offset plug is the fill plug. Do not open the other two plugs.
Fill the reservoir until the fluid touches the threads on the pump
case. Once full (on all jacks), replace the cap and run through the
priming procedure to remove excess air.
