Chapter 10 - 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.
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.
• Make sure that the transmitter batteries are
fully charged. (Rechargeable batteries are
good for 11 months or 200 charges)
• 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 electrically.
Solutions:
• 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.
• Make sure that the parking brake is engaged.
• Make sure that the parking brake switch is
working properly. Check the parking brake
switch by performing a continuity test. If the
switch is defective, simply replace it.
• Make sure the “Power” LED is on outside the
receiver door cover. This light is the upper
light on the receiver door. If the light does not
come on, check wiring back to the fuse. If
the fuse is OK, check system ground wires
and connections.
• Make sure the green LED on the receiver
door is lit green. This light will come on when
the red e-stop is pulled upward and the toggle
switch is activated on the transmitter. If the
radio system does not link up and no green
light is lit on the receiver - make sure that the
battery is fully charged, check the battery
contact points to make s ure they are not
tarnished or corroded. Clean contact points
and recharge or replace the battery.
• When battery voltage is acceptable, the
power LED light on the transmitter will be
solid. If the voltage becomes low, the LED
light will begin to blink and the battery will
need to be charged or replaced.
Problem: Crane operates slowly.
Solutions:
• Make sure that the crane is receiving the
recommended GPMs to operate.
• Check the level of hydraulic fluid in the
reservoir. Add fluid as needed.
• Check to see if the valve bank proportional
valve is operating.
• Make sure the proportional valve is receiving
12V power when operating a function.
