– Hydraulic fluid is a hazardous materials and ought to be disposed of correctly in accordance with native laws. Don’t pour it down the drain or on the bottom.
Figuring out the Bleeder Valve
Finding the bleeder valve on a ground jack is essential for efficient bleeding. Here is an in depth information that can assist you discover it:
1. Examine the Base of the Ground Jack:
Most ground jacks have the bleeder valve located on the base, close to the pump mechanism. Search for a small, knurled knob or screw-like projection.
2. Look at the Pump Deal with:
On some fashions, the bleeder valve is built-in into the pump deal with. Examine for a small valve stem or a knob hooked up to the deal with. Rotate the deal with to reveal the valve.
3. Examine the Hydraulic Cylinder:
In uncommon instances, the bleeder valve could also be positioned on the hydraulic cylinder itself. Search for a small, capped becoming or a screw-in valve close to the cylinder.
Connecting the Bleeder Package
Earlier than you proceed, guarantee the ground jack is on a flat and steady floor. Find the bleeder valve, which is often a small screw or bolt on the facet of the jack cylinder. Clear the world across the bleeder valve to forestall any contaminants from getting into the hydraulic system.
Join the bleeder hose to the bleeder valve. The hose ought to be lengthy sufficient to succeed in your fluid reservoir. Slide the hose clamp over the hose and tighten it securely to forestall any leaks.
Join the opposite finish of the bleeder hose to the fluid reservoir. You should utilize a funnel or a syringe to assist pour the fluid into the reservoir. Make sure the reservoir shouldn’t be overfilled, as this may trigger air to grow to be trapped within the system.

| Step 4: | Pump the ground jack deal with a number of occasions to construct up stress. |
Bleed the Jack Manually
In case you are bleeding air from the ground jack with out a hydraulic pump, use a flathead screwdriver or related device and insert it into the bleeder valve. Rotate it counterclockwise to open the valve and permit the air to flee. This may create a hissing sound, and when it’s accomplished, the jack will launch solely fluid. Shut the bleeder valve. Repeat this course of a number of occasions (pump and launch) till no extra air is launched.
Bleed the Jack Utilizing a Hydraulic Pump
To bleed the jack utilizing a hydraulic pump, first take away the air vent screw positioned on the facet of the pump. Connect the hose of the pump to the bleeder valve and open the pump valve. Repeat pumping and releasing the jack a number of occasions till no extra air is launched. Shut the valve and detach the pump hose from the bleeder valve.
To Pump or To not Pump: Bleeding with or with out a Hydraulic Pump
The method of bleeding a ground jack may be accomplished with or with out the usage of a hydraulic pump. When bleeding a jack with out a pump, it could take further energy and a number of makes an attempt to drive the air out by way of the bleeder valve. With a pump, the method can be sooner and fewer effort is required.
| Bleed with or with out pump | Professionals | Cons |
|---|---|---|
| With pump | Sooner | Requires a hydraulic pump |
| With out pump | Slower | No pump required |
