Why is my JLG Lifting Systems operating hot?
- HhflowersJul 28, 2025
If your JLG Lifting System is operating hot, it could be due to several reasons. First, check the hydraulic fluid level and fill the reservoir to the proper level, as an insufficient amount of fluid won't meet the system's cooling demands. Another cause might be a failing or obstructed heat exchanger; make sure it's receiving adequate airflow and is in good operating condition—repair or replace it if necessary. Lastly, a system relief valve that's unseated for too long or has failed can cause overheating. In this case, repair or replace any malfunctioning relief valves and verify the machine loads aren't excessive.
