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, first try to operate the crane
manually. This is done by turning the manual override knob on the flow 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 flow or GPMs. Check the flow
by using the flow meter to determine the GPMs. It is possible that the hydraulic pump is
getting weak. If this is suspected, contact Stellar Customer Service.
Problem: Crane will operate manually but will not operate by radio remote.
Solutions:
• Make sure that there is 12V power going to the radio receiver. If there is no power going to
