7.1 Troubleshooting Toolbars
7.0 Troubleshooting
Probable Cause
Solution
Incomplete engagement of 
hydraulic quick couplers.
Inspect quick couplers to ensure complete en-
gagement.
Lock valves for shanks are 
set in closed position.
Ensure that both lock valves, one at the manifold 
and one at the tractor quick coupler, are set to 
the open position.
No electrical power to 
shank solenoid valve.
Check for broken wire in harness to solenoid 
coil.
No electrical power to 
shank pressure adjustment 
motor.
Check for broken wire to shank pressure adjust-
ment motor.
Tractor hydraulic selector 
valve not holding pressure.
Disconnect coupler at Circuit #1. If pressure is 
now adjustable, repair the tractor selector valve 
(make sure the lever is in working position not 
float).
Solenoid coil 
malfunctioning.
Activate solenoid valve manual override. If the 
shank pressure responds properly, replace the 
coil also check for power going to coil.
Shank solenoid valve 
cartridge contaminated.
Remove solenoid valve cartridge per repair in-
structions in the maintenance section of this Op-
erator’s Manual, inspect to make sure all o-rings 
are not damaged, then clean and replace.
Shank pressure gauge 
malfunctioning.
Remove and replace pressure gauge if not re-
sponding to increase and decrease of pressure.
Cannot Adjust Shank Pressure
Shanks do not maintain trip/packing pressure on hilly
terrain
Probable Cause
Solution
The “IN” pressure gauge 
indicates less than 1200 psi.
Inspect quick couplers to ensure complete en-
gagement.
Excessive field operating 
speed.
Reduce field operating speed. Note:  Trip/packing 
pressure may be momentarily increased by acti-
vating hydraulic Circuit #1 while passing through 
a shallow dip in the terrain.
Intermittent electrical 
power supply to shank 
solenoid coil.
Ensure all electrical connections are fully engaged 
and no open electrical circuits to coil.
