Why won’t my JLG RT2669 Lifting Systems shift or is slow to start?
- A
  Alexandra CastroAug 6, 2025
  If your JLG Lifting Systems won’t shift or is slow to start, it could be due to obstructed flow through the servo control signal lines; ensure these lines are clear and signal pressure is adequate. Also, the size and condition of the supply and drain orifices affect shift rate; verify the correct orifices are installed and not obstructed, cleaning or replacing them as necessary.

Why is there excessive noise and vibration in my JLG RT2669?
- A
  anthonywatkinsAug 15, 2025
  Excessive noise and vibration in JLG Lifting Systems can stem from several issues. Insufficient hydraulic fluid may cause cavitation; thus, refill the reservoir to the correct level, ensuring adequate oil supply and unobstructed lines. Trapped air can also cause cavitation, so purge all system lines and components. A loose or incorrect shaft coupling can produce vibrations; ensure the correct coupling is properly fitted. Misaligned shafts create friction, so align them correctly. Finally, overly viscous hydraulic oil can cause cavitation; replace it with fluid appropriate for operating conditions.

What to do if my JLG Lifting Systems is operating hot?
- D
  Donna BurkeAug 27, 2025
  Overheating in JLG Lifting Systems can occur if there is not enough hydraulic fluid to meet cooling demands; therefore, fill the reservoir to the correct level. A faulty or obstructed heat exchanger can also cause overheating; ensure adequate airflow and good operating condition, repairing or replacing as needed. Finally, a system relief valve that is unseated or fails can lead to overheating; repair or replace any malfunctioning relief valves and verify that machine loads are not excessive.
