Floor jacks have become very popular both on construction sites and for professional use as well as for personal use. There are two different types of jacks, bottle jacks, and floor jacks. Both work on the same system, except that, unlike the bottle jack, the jack is placed on its side and has different internal seals and check valves.

All jacks work in 6 parts; A reservoir that holds the fluid, a pump that moves the fluid, and a valve that provides flow to the master cylinder; At this time, the liquid rises above the piston, and then the relief valve returns the liquid to its original place, in the reservoir. Jacks are very durable and last a long time, if you take good care of them, you will extend their life even more. They are ideal for transporting heavy equipment or construction materials, as well as for personal use when changing tires on your vehicle.

First, you need to get to know your Jack. When using it, make sure it is standing firmly on a hard and flat surface. If the surface is soft, the jack may even sink under gravity. It should also not be placed on an uneven surface, as it may tip over when lifting a load. There are cases when the jack is literally thrown out of position, and the load falls; this is especially dangerous if you are changing a car tire. Also, remember that if you have a bottle cage, never put it on its side or ram it upside down, as this can cause an accident during our work.

There are many different types of jacks available, depending on the purpose and weight load you need them for. Make sure you buy the correct jack for the intended purpose as it is important not to overload it as this will break the internal seals. If you are concerned that you may have overloaded the jack, you can check floor jack for leaking oil around the ram. This is a sure sign.

Although these are floor jacks

Although these are floor jacks, there is no need to add fluid or hydraulic oil throughout their life and use. Only in certain cases, when you find a leak, you need to add additional oil. Sometimes, in unusual cases, the air gets in, and in this case, oil can be added to alleviate lifting problems. If you think oil needs to be added, you can do so by first locating the three screw heads.

Two are for checking the valves, and the third is for adding fluid. Whatever you do, do not loosen the valve screws. You can easily lose small parts. On the cylinder body, you will find the fluid fill screw. “Oil” is written on it. This is the only place you can add oil, don’t try to add oil anywhere else. When adding oil, make sure the reservoir is full while waiting for the fluid to come out of the hole. It is also important that the ram is in the lowest position.

There are cases when air entered the main cylinder of the hydraulic jack. To remedy this, raise the ram all the way up and lower using the relief valve. You should hear a slight “psst” sound as the air escapes from the master cylinder; this can be done by loosening the oil filler screw slightly. Not all the air may come out the first time, so you may need to repeat this several times. Again, do not loosen the other two screws that control the valves; if you do, just add more air to the cylinder.
