Troubleshooting
Problem Solution
Excessive cable wear Check cable and roller for obstruction or wear. Remove obstructions.
Check that roller is turning properly. Replace roller or roller bushing if
necessary.
If necessary, replace worn cable.
Pressure increases Check for clogging in boom hoses. Remove obstruction.
Check if boom hoses are pinched. Use cable ties to keep hoses from
kinking.
Optional electric-hydraulic control not
working If valve does not work and indicator lights are not lit, check for a blown
fuse, damaged wiring or a bad switch.
If valve does not work but indicator lights are lit, check that system is
properly grounded. Ground valve by running a wire from the tractor
frame to the coil nut on top of the valve.
Restricted oil flow to optional electric-
hydraulic control Do not mix and match styles of tips and couplers.
Check that hydraulic hoses are not blocked, damaged or kinked.
No oil flow and no clicking sound
from valve on optional electric-
hydraulic control Check valve cartridge for internal contamination. Before removing car-
tridge, relieve all hydraulic pressure and remove all hydraulic hoses
from ports. Contact your Great Plains dealer for cartridge-cleaning
instructions.
