Chapter 3 - Troubleshooting
This chapter will list a number of potential problems that may occur while operating the crane.
Most problems are easily solved using the solutions portion of this chapter. If problems persist,
please contact Customer Service at Stellar Industries 1-800-321-3741.
Prior to troubleshooting:
Always make sure the parking brake is engaged and the PTO is engaged (if equipped).
To determine if there is an electrical or hydraulic problem, rst try to operate the crane manually.
This is done by turning the manual override knob on the ow valve, then operating the individual
solenoid valves located along the valve bank. If the crane operates, there will be an electrical
problem to trace. If the crane does not operate using the manual overrides, there is a problem
within the hydraulic circuit.
Problem: Crane will not operate.
Solutions:
• Make sure that the parking brake is engaged.
• Make sure that the PTO is engaged.
• Make sure that there is 12V power going to the radio receiver. If there is no power going to
the receiver, trace back to the power source and check for a blown fuse or loose ground
connection. Refer to radio remote troubleshooting guide at the end of this chapter.
• Make sure that the transmitter batteries are fully charged.
• Make sure that the hydraulic pump is operating at its rated ow or GPMs. Check the ow by
using the ow meter to determine the GPMs. It is possible that the hydraulic pump is getting
weak. If this is suspected, contact Stellar Customer Service.
