8.0 TROUBLE-SHOOTING
SYMPTOM
POSSIBLE CAUSE
SOLUTION
Cannot adjust
shank
pressure.
Incomplete
engagement of
hydraulic quick
couplers
Inspect quick couplers to ensure complete
engagement.
Meter Wheel Switch not
set to “ON”.
Ensure that both the Meter Wheel Switch and Main
Power Switch are “ON”.
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 adjustment
motor.
Shank relief motor
seized.
Release set screw on collar and to increase
pressure turn clockwise and to decrease pressure
turn counter clockwise.
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
instructions in the MAINTENANCE section of this
Operator’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
responding to increase and decrease of pressure
Shank orifice blocked.
Remove cap and orifice and check to see if
contamination is block off orifice. Clean out and
reinstall.
