  Regardless of the type of long ram jacks or the application, there are some issues that are common within this tool category. Maintenance problems can compromise a jack’s ability to operate efficiently and negatively impact operator safety. If your equipment exhibits these signs, it is important to coordinate jack repairs right away.

  Jack Does Not Fully Extend or is Slow to Release
  Hydraulic jacks depend on fluid-driven pressure to create movement. When the flow is compromised, it can cause problems with lifting mechanisms.

  Squeaky or Damaged Wheels
  Excessive noise issuing from your wheels could mean it’s time to replace those parts. Often, the application of heavy oil provides enough lubricant to prolong the life of metal support structures.

  Damaged Frame
  Without a structural sound frame, your entire unit could literally fall apart under a heavy load. This type of damage typically cannot be repaired and requires the purchase of a new hydraulic jack.

  Foamy or Milky Oil
  Discolored or frothy oil means water has infiltrated the system. If not remedied quickly, this condition will cause irreversible internal corrosion.

  Handle Kicks Back
  Stop using your hydraulic jack immediately if the handle kicks back up after a down stroke. This condition is extremely dangerous for operators. Fortunately, a repair professional can restore the unit’s function.

  Leaks
  Depending on which fluid is leaking from your unit, this sign could indicate a range of potential problems. A thorough examination of the unit is necessary to decipher the issue.

  Rams Won’t Lift
  When rams won’t respond properly, this usually points to a lack of hydraulic fluid. Simply add more fluid, turn the jack to its release position, pump a few times to release trapped air, and then refill the reservoir. Once the seal is replaced, the unit should function properly.

  Overloaded Jack Trips Safety Valves
  If the load is too heavy, the jack’s safety valves will engage, which will cause the jack to stop lifting. Refer to the user manual to identify the safety valve and follow instructions to reset it.
