Hydraulic Fluid Leak

This procedure will guide you through the steps to troubleshoot a hydraulic fluid leak on your Goodnature SX-280.

Mitigating or precluding hydraulic fluid leaks can be handled by frequently checking and tightening all of the fittings and hoses on your SX-280 press. It is recommended to perform this maintenance once a week. However, you may  still experience a leak at a fitting, or a defective hose, which can lead to press operation failure.

If you are experiencing a fluid leak at a fitting or hose-end, Follow these steps for troubleshooting and repair:

  1. Turn off your SX-280 press.
  2. Tighten the fittings on the SX-280 which appear to be leaking.
  3. Clean the area off of all fluid and turn your SX-280 back on.
  4. Watch closely the hose-end or fitting suspected of leaking.
  5. If there is no apparent accumulation of fluid, place the press under pressure by moving the platen to either direction.
  6. When the platen closes and proper pressure is achieved(1800 psi for forward and 2200 psi for reverse), check the suspected area again to see if fluid is accumulating.
  7. If fluid begins to accumulate at the fitting joint, or appears to be coming from the hose-end, you may be experiencing a defective O-ring in the fitting or a loose or defective hose-end, in which case replacing the fitting and hose will be necessary.

Goodnature recommends having a set of extra hoses on hand to guarantee that you do not experience the loss of production time. However, if this is not possible, you may contact Goodnature and have hoses or fittings shipped out to you. (It may also be possible that O-rings for fittings be found at your local Hydraulic parts store).
