TROUBLESHOOTING CONTINUED
Reason: Correction:
6. Conveyor relief valve open to return line. Using relief valve testing adapter and flow meter, test valve for
opening pressure. If not 2000 PSI (137.9 bar), replace relief
valve.
7. Jammed or frozen spinner motors. Free up. If not possible, replace as required.
8. Jammed or frozen conveyor. Free up conveyor.
9. Jammed or frozen conveyor hydraulic motor. Replace motor.
10. Conveyor hydraulic motor shaft key sheared. Replace key.
11. Pump speed is not adequate to provide
sufficient flow to maintain spinner speed.
Increase engine speed.
12. Insufficient hydraulic oil flow at normal
driving speeds.
Check PTO-Pump matching. If insufficient flow results, install
higher percent PTO or use larger pump (Special).
13. Defective spinner control valve. Replace valve metering spool spring. If no improvement,
replace spinner control valve.
14. Cab control is for conveyor only—spinners
run anytime vehicle engine is running, PTO
is engaged and spinner control valve is in a
running position.
None required. This is a normal condition. To stop spinners,
set spinner control valve at “O” position, disconnect PTO, or
shut off vehicle engine.
15. Excessive oil is being pumped. 1. PTO percentage too high. Change PTO to smaller
percentage or use smaller pump.
2. Pump is too large. Do not exceed 40 GPM (151.4 LPM)
pumping rate. Change to smaller pump or use smaller
percentage PTO.
3. Pressure drop in control valve is sufficient to run lightly
loaded conveyor motor. Shut off pump drive by disengaging
PTO shaft.
16. Worn motor (spinner or conveyor) Motor heats up at an excessive rate (check for this heating
when system is cold.) Replace motor.
17. Improper or deteriorated hydraulic oil. Replace hydraulic oil with proper specification oil and replace
filter.
18. Pinched or obstructed hose, hydraulic line or
fitting.
Clear obstruction or replace part. Straighten kinked hoses.
19. Driving too fast for application rate. Shift truck transmission to a lower gear. Will not normally
occur if within maximum application rates.
20. Defective radar. Check speed on console. Repair or replace radar as required.
21. Control processor’s power is in “Off”
position.
Turn on control processor.
22. Involves the controller. Refer to control manual.
