Bleeding a Craftsman 3-Ton Floor Jack: A Quick and Easy Guide
If your Craftsman 3-ton floor jack isn't lifting as it should, chances are it needs to be bled. Air can get into the hydraulic system over time, which can cause the jack to lose power. Bleeding the jack is a simple process that can be done in a few minutes.
Why is it important to bleed a floor jack?
A floor jack that isn't bled can be dangerous. If the jack fails while you are lifting a vehicle, it could cause serious injury or damage to the vehicle. Bleeding the jack removes any air from the hydraulic system, which ensures that the jack will operate safely and efficiently.
How to bleed a Craftsman 3-ton floor jack
- Park the vehicle on a level surface and engage the parking brake.
- Place the floor jack next to the vehicle and raise the saddle to its highest position.
- Open the bleeder screw on the top of the jack.
- Slowly lower the saddle until hydraulic fluid begins to flow out of the bleeder screw.
- Close the bleeder screw and raise the saddle to its highest position.
- Repeat steps 3-5 until no more air bubbles come out of the bleeder screw.
- Tighten the bleeder screw and lower the saddle.
Your Craftsman 3-ton floor jack is now bled and ready to use.
By following these simple steps, you can bleed your Craftsman 3-ton floor jack and ensure that it is operating safely and efficiently.

Preparation
Gather materials: You'll need a flathead screwdriver, a shop rag, and a bucket or drain pan.
Position the jack: Place the jack on a flat surface and extend the ram all the way up.
Bleeding the Jack
- Locate the bleeder screw: It's usually a small, hexagonal screw located on the hydraulic pump.

Open the valve: Carefully open the bleeder screw more, allowing air and fluid to escape.
Collect fluid: Hold the shop rag over the opening to absorb the escaping fluid and prevent a mess.
- Tighten the screw: Once no more air or fluid comes out, close the bleeder screw.
Replenishing the Fluid
- Locate the filler plug: It's usually a plastic or metal plug located on the side of the pump.
- Remove the plug: Use the flathead screwdriver to remove the filler plug.
- Fill the jack: Use a funnel to pour hydraulic fluid into the filler port.
- Replace the plug: Reinsert the filler plug and tighten it securely.
Testing the Jack
Pump the jack: Pump the jack handle several times to raise and lower the ram.
Check for leaks: Inspect the jack for any leaks around the bleeder screw or filler plug.
Tips
