  Virginia SanchezAug 8, 2025
  The slow working movements of your Farmi Forest Construction Equipment crane may be due to several reasons. The pump might be too slow, so check the pump's rotating speed. There could be a faulty pump, in which case you should change or get the pump fixed. Leaks or obstructions in the oil lines can also cause this issue, so inspect the oil lines. Finally, the oil might be too thick; if so, change to a thinner, correct oil grade.

  If the movements of your Farmi Forest Construction Equipment crane are jerky, it could be due to air in the hydraulic system. Check the oil level and bleed air from the system. Also, ensure there is enough oil, checking for obstructions or leaks on the inlet side and adding oil if needed. A faulty pump can also cause jerky movements, so check the pump and get it fixed.

  Anthony GibsonAug 16, 2025
  If your Farmi Forest Construction Equipment crane's working movements are powerless, it could be due to not enough oil, in which case you should add oil and bleed air from the system. Other potential causes include a faulty pump (change or get the pump fixed), a faulty relief valve or shock valves (change the relief valve or shock valves), a faulty control valve (change or get the valve fixed), or faulty cylinders or seals (check the cylinders and change the seals).

Why are the Farmi Forest FARMI 4670 crane's descending movements slow?
- K
  Karen BeanAug 21, 2025
  Slow descending movements in your Farmi Forest Construction Equipment crane can be caused by obstructions in the oil lines; check the lines and the chokes. Another cause may be a clogged-up return filter; clean or renew the filter. Lastly, if the oil is too thick, change to a thinner, correct oil grade.

  Tiffany GeorgeAug 26, 2025
  If the booms on your Farmi Forest Construction Equipment descend by themselves, the issue might be a faulty control valve; inspect the control valve and get it fixed. It could also be due to faulty cylinders or hoses or a faulty shock valve; fix the leakage point and check cylinders and seals, then check, clean, and adjust.

Why are the Farmi Forest Construction Equipment crane's movements too fast?
- B
  Benjamin LandryAug 29, 2025
  If the movements of your Farmi Forest Construction Equipment crane are too fast, it may be due to a rotation speed that is too high or a pump that is too big; choose a correct speed of rotation and correct pump size. Another possible cause is incorrect operation; learn to open the control valve to a suitable degree.

How to fix Farmi Forest Construction Equipment control valve’s spindles sticking?
- D
  Dylan HughesSep 3, 2025
  If the control valve’s spindles are sticking on your Farmi Forest Construction Equipment, it may be because the valve’s fixing screws are too tight; check the screws' tightening torque to 50 Nm (5 kPm). The valve might also not be on a level mounting base; mount the valve on a level base. Finally, the valve’s tie bolts might be too tight, or the spindle faulty; check the screws' tightening torque (contact the manufacturer), or change to a new block with spindles.
