Your floor jack needs proper bleeding when it is not showing a good working capacity. Sometimes air gets trapped inside the floor jack; there can be a leakage and lack of fluid. Then it’s necessary to bleed the floor jack.
Bleeding a floor jack asks you to go through some procedure. Not all floor jack’s bleeding process is the same. A proper guideline on different types of jacks, cleaning, replacing, draining, refilling procedure, and so on will help you in bleeding your floor jack.
How to Bleed a Floor Jack?
Your jack might not work in a steady-state, so you need to bleed it to prevent its lingering move. Various types of floor jacks such as hydraulic jacks, scissor jacks, and bottle or piston jacks, low profile jacks, etc. offer different bleeding systems.
Hydraulic Jack
Hydraulic floor jack lifts heavyweight by creating force in the cylinder. It uses incompressible liquid to operate. This liquid is forced into the chamber through a pumping plunger and thus the plunger moves. Bleeding this jack correctly will keep up its performance in pace.
Clean Device and Remove Fill Plug
Dirt and debris can cause damage to the cylinder. So, before doing the job, clean the device nicely. Failure in the plug is a major reason for the machine not working accurately. Take a screwdriver to pry up the rubber plug which you will find on the top of the cylinder.
Change Hydraulic Fluid
Use a bucket under the floor jack and turn it on until the fluid gets drained out. Make sure that the whole cylinder is empty and clean. Otherwise, clean it with compressed air. Then, fill it with new fluid with the help of a funnel as soon as possible.
Replace Rubber Plug and Test
Set the plug into the hole of the cylinder and press it gently. While placing it back, you must ensure that it is clean and seated flat without any hole/space in it. Hopefully, all problems are solved. Do a test when you put any weight on it. Lift the arm to check. Assure that the pressure is capable of holding the given weight.
Bottle Jack
Bottle jacks are attached vertically and more straightforward that helps to lift more than 50 tons of weight. These jacks can lift various types of objects. Some of these jacks are smaller and cheaper. It can move easily and its bleeding procedure is quite easy
Release the valve
To purge air, first, you have to free the valve and pump the handle several times. Then, tip the jack over to make the oil-filled plug facing upwards on the level.
Remove Filter Plug and Replace Fluid
Remove the filter plug. Then, bring the oil-filled plug on the side to let the air release. Change the jack fluid or add needed fluid. Keep everything clean while doing this.
Insert Handle and Close the Valve
Insert the handle inside the socket and force it for several times to get the air out. Then close the released valve tightly and move it clockwise to close the valve.
Scissor Jack and Low Profile Jack
Like other jacks, we need to do almost the same things to bleed these floor jacks. First, you have to extend the ram piston before moving on weight. After that, release the pressure valve with a screwdriver and turn it counterclockwise.
Open filter plug from the main body of the machine to let the trapped air escape and again reattach the plug. You have to repeat this until the whole air has come out.
How Do You Bleed a Daytona Floor Jack?
Daytona floor jack has thick steel. Its welds are so fresh and liberal. Moreover, it is metal to metal interfaced. You need to bleed this floor jack when the oil level is low. It’s available above the cylinder.
Remove Shipping Clip and Attach the Handle
First, wear safety goggles. Then press jacks handle socket down to free the tension and disconnect the wire clip. Keep raising the handle socket slowly until the pressure gets released. After that, remove the wire clip and slide the handle upwards to the level and release it.
Release Trapped Air
Firstly, disconnect the screws and remove the fill plug from the cylinder. Insert the handle inside its socket to release the valve. Turn it counterclockwise. Pump the handle until the air gets out properly. Then, reverse the procedure.
How do you Bleed a US General Floor Jack?
Lower the handle first. Clean the area surrounding the plug before releasing it. Then, move the handle clockwise to relieve the valve. After that, remove the oil plug and pump the handle to release the inside air. Then, reinstall the system.
How Do You Drain and Refill a Bottle Jack?
Draining and refilling fluid increases jacks lifting capability. Choose the recommended oil before using it because the higher or lower oil level can limit its capacity.
Draining a Bottle Jack
To drain a bottle jack, first, loosen the valve screw counterclockwise. Clean all the dirt and debris before opening the plug. After that, open the cylinder and release the fluid. You need to clean it properly as well.
Refilling a Bottle Jack
Put the funnel on the mouth of the filter port. Hold it tightly with your hand while doing this. Take the fluid and slowly pour it with the oil or other correct substance.
Then, plug in the filter port and complete the whole system to reinstall it. Fill the fluid quickly when it is low. Filling fluid on times will help your jack to perform its job nicely for years.
Frequently Asked Questions
Q: What oil do you put in a floor jack?
Ans: You should use any standard 10W hydraulic oil for use. But it must be of appropriate viscosity so that it can work properly. You can also use ATF hydraulic oil.
Q: Can I use motor oil on my floor jack?
Ans: Yes, you can use 5W-30 motor oil or any correct substances like power steering fluid, ATF, or DO NOT USE ATF that are handy and work well.
Q: What should be the height of a floor jack lift?
Ans: 20 inches is the suitable height for most of the floor jacks and is the maximum lift too.
Conclusion
Your floor jack cannot hold up its capacity if it has air trapped inside or with leakage. So, bleeding floor jack, replacing its fluid, and cleaning the cylinder is necessary. It also increases its performance.
Bleeding a floor jack is done by some similar procedures. But in some cases, it depends on the pressure it can take and also on the jack machine configuration.
