Why is my JLG Boom Lifts system operating hot?
- LLori AndersonJul 28, 2025
Your JLG Boom Lifts system might be running hot due to several reasons. It could be due to an insufficient amount of hydraulic fluid, which fails to meet the system's cooling demands. In this case, fill the reservoir to the proper level. Another cause might be a failing or obstructed heat exchanger, which also prevents adequate cooling. Make sure the heat exchanger is receiving enough air flow and is in good condition; repair or replace it if needed. Finally, a system relief valve that's unseated for too long or malfunctioning could cause overheating. Repair or replace any faulty relief valves and check that the machine's loads aren't too high.
