TROUBLESHOOTING GUIDE
Floor cut has grooves.
Rear
gangs
out
of
adjustment
relative to the front disc unit.
Adjust rear gang to the right slightly
less than the average width of the
groove bottoms.
Machine bounces in the field.
Field
conditions
too
rough
for
operating speed.
Reduce operating speed. Work
twice if necessary.
Draft comp pressure is too low.
Increase draft comp pressure 200 -
300 psi relative to the
recommended setting.
Draft comp circuit out of adjustment.
Increase draft comp pressure 200 -
300 psi relative to the
recommended setting.
Floor cut irregular.
Adjust rear gangs laterally.
Air is trapped in the gauge cylinders.
Remove air from the cylinders by
holding hydraulic circuit in extend
position for 5 to 10 seconds after full
extension.
Uneven operating depth.
Wing frame(s) not operating at
uniform depths.
See
Front Gauge Points” on page 4-3
.
Rear
gauge
points
out
of
synchronization.
Synchronize cylinders by holding
hydraulic circuit in extended position
for 5 to 10 seconds after full
extension.
Hydraulic wing down pressure is not
operating (correctly).
Make certain that the indicator
gauge is showing the recommended
pressure and the flow is not
excessive.
Hydraulic wing down pressure is too
high and center section is too light.
Reduce wing down pressure.
Hydraulic wing down pressure is too
low and the wing tips are too light.
Increase wing down pressure.
Rear gauge points not uniform.
Rear
gauge
points
out
of
synchronization.
Synchronize cylinders by holding
hydraulic circuit in extended position
for 5 to 10 seconds after full
extension.
Cylinder leaking internally.
Repair/replace cylinder.
Machine does not hold consistent
working depth.
Rear gauge point limit valve leaking.
Replace rear limit valve (on
left-hand wing frame).
Front gauge point limit valve leaking.
Replace front limit valve (on hitch).
Front and/or rear gauge points out
of synchronization.
Synchronize cylinders by holding
hydraulic circuit in extended position
for 5 to 10 seconds after full
extension.
Wings fold too slowly.
Restrictors
are
not
properly
installed.
Smart restrictor fittings should be
installed in wing cylinder base end
points.
Wings fold too fast.
Restrictors not properly installed.
Black restrictor fittings should be
installed in the rod ends of wing
cylinders.
