What to Do When the Aerial Work Platform Keeps Flashing 'CH' and Won't Move?
1 Answers
When the aerial work platform is overloaded, it may fail to lift. The best solution in this case is to ensure no overloading during loading and unloading operations. If the equipment's oil return valve remains open, it can also prevent lifting. Tightening the oil return valve can resolve this issue. Failure to lift may also occur when the manual pump's check valve gets stuck, causing reset malfunction. Further troubleshooting, cleaning, or replacing the hydraulic oil with clean fluid may be required to address the problem.
