Why stellar labs 5520 crane will not operate?
- Ppeggy70Aug 15, 2025
The crane may not operate because the parking brake is not engaged, or the PTO is not engaged. Ensure the transmitter batteries are fully charged. Also, ensure there is 12V power going to the radio receiver, and if not, trace back to the power source to check for a blown fuse or loose ground connection. Check that the hydraulic pump is operating at its rated flow (GPMs); if the pump is weak, contact Stellar Customer Service.
