TROUBLESHOOTING CONTINUED
• Symptom: Spinner motors do not turn when spinner control valve is in running position. See reasons 1, 2,
3, 4, 5, 7 & 21.
• Symptom: Spinners turn but conveyor does not run in manual mode. See reasons 6, 8, 9, 10 & 21.
• Symptom: Console in operation mode, but the conveyor does not move when the machine moves. See
reasons 6, 8, 9, 10 & 21.
• Symptom: Spinner speed does not stay constant. See reasons 4, 5, 11, 13, 21 & 22.
• Symptom: Hydraulic oil overheats (200° F (93 C°) or hotter). See reasons 1, 4, 6, 15, 16, 17 & 18.
• Symptom: Conveyor does not run with cab control “on”, PTO driveline engaged and tractor driving forward.
See reasons 20 & 21.
• Symptom: Conveyor runs erratic. See reasons 19 & 21.
• Symptom: Conveyor runs when control switch in cab is in “Off” position. See reason 14.
• Symptom: Conveyor starts to run when PTO driveline is engaged. See reasons 12 & 21.
• Symptom: Hydraulic system pulsates. See reason 20 & 22.
• Symptom: Spinners run with cab control in “Off” position. See reason 23.
• Symptom: Controller application or programming. Refer to the control manual’s Troubleshooting section.
• Symptom: Undesirable spread pattern. See
G4 Spread Pattern
section at the back of this manual.
• Symptom: Brakes are sluggish or noisy. See “Brakes” in
Lubrication & Maintenance
section.
• Symptom: Lights are not functioning. See “Electrical Schematic” in
Troubleshooting
Section.
• Symptom: Light flashes and buzzer sounds intermittently. Conveyor runs in jerks. See reasons 19 & 21.
Reason: Correction:
1. Hydraulic oil level low. Add hydraulic oil as necessary to maintain level around mid-
point of sight gauge.
2. Shut Off valve on oil reservoir not open. Open valve fully by turning counter clockwise until it stops.
3. Hydraulic Pump is not rotating. a. Pump is disengaged. Shift into engagement.
b. Drive line has failed. Repair or replace.
c. Key in pump shaft has failed. Replace key.
d. U-joint pin or key has failed. Replace pin or key.
4. In line relief valve set too low. In line relief valve pressure should be 3100 PSI (214 bar). If
unit is not equipped with a pressure gauge, install one at main
relief valve. Disconnect pressure line from main relief valve
and reconnect to flow meter and load valve. Open load valve
fully and run tractor engine at field operating speed with pump
engaged. Slowly close load valve until pressure reaches 3100
PSI (214 bar). If this pressure cannot be reached, adjust relief
valve until gauge reads 3100 PSI (214 bar). CAUTION: Do not
set pressure above 3100 PSI (214 bar).
