Why won’t my JLG RT3369 shift or is slow to start?
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 RT3369?
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?
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.
