A hydraulic jack is designed to make it easier to move heavy items. It can help people lift a heavy load without straining. Your jack will not last forever. There are several signs that indicate you need a new jack.
The Jack Does Not Fully Release
Jacks depend on fluid and pressure in order to move. It will not be able to lift properly if the flow is compromised.
The Wheels Are Squeaky or Damaged
If you hear a lot of noise coming from the wheels, then it may be time for you to replace those parts. You may need to use oil in order to lubricate those parts.
The Rams Will Not Lift
If your rams will not respond, then hydraulic fluid may be to blame. You may need to add fluid and return the jack to its normal position. The unit should be able to function normally after that.
Leaks
It is never good for you to have fluid leaking from the unit. The type of fluid that is leaking can determine what the problem is. You will also need to have the problem inspected in order to determine the cause of it.
The Oil Is Milky or Foamy
If the water is milky or foamy, then this is a sign that water is inside of the system. Internal corrosion can result if this problem is not rectified. It is time for you to get hydraulic jack if the oil is milky or foamy.
