Troubleshooting Guide
Problem Cause Corrective Action
Compressor will not run 1. air system is off
2. hydraulics disengaged
3. no power from battery
4. electrical connection issue
5. shut off psi(145psi) reached
6. worn compressor
7. Improper pressure switch function 1. Flip switch to ON on cab controller
2. engage compressor hydraulic circuit
3. check power connections from battery, check
2940-150 breaker at the battery
4. check harnesses from cab controller to
compressor
5.compressor will restart after tank pressure
drops below 125psi
6. replace compressor
7. replace pressure switch
Compressor runs
continuously/air flow
lower than normal,
Compressor Run Time
High warning on cab
controller if compressor
runs continuously for 15
minutes 1. excessive air usage
2. loose connections/air leak
3. Improper pressure switch function
4. clogged air filter element
5. worn compressor
6. defective safety valve
7. tank drain valve open
8. water separator valve leaking 1. decrease air usage
2. perform leak check on all circuits
3. replace pressure switch
4. clean/replace filter element
5. replace compressor
6. replace safety valve
7. close tank drain valve
8. replace water separator valve
Compressor struggles
to build/won’t build
145psi flow control valve adjustment
needed flow control valve adjustment needed
Excessive noise from
compressor 1. loose mounting bolts
2. worn bearings
3. cylinder or piston is worn
4. compressor over speeding 1. tighten bolts
2. replace compressor
3. rebuild compressor
4. check compressor RPMs & slow motor down
if needed, hydraulic plumbing of the compressor
is incorrect
Excessive moisture in
circuits 1. excessive water in air tank
2. high humidity 1. drain tank, drain tank more frequently
2. move compressor to area with less humidity.
Hydraulic motor front
seal leakage 1. case drain clogged or unplugged
2. case drain not plumbed correctly 1. remove case drain plumbing and clean out
debris/obstruction, replace seal
2. Plumb case drain according to the
instructions, replace seal
Not able to adjust air in
a circuit 1. regulator adjustment knob locked
2. selector valve has activated
incorrect circuit
3. defective regulator 1. unlock regulator adjustment knob (pull)
2. adjust the selector valve to correct circuit
3. replace regulator
Too much residue in the
strip Row cleaner not set properly 1. make row cleaner more aggressive
2. make row cleaner less aggressive (if residue
is being thrown on row by adjacent row units
Strips are not desirable 1. Large clods are left on/in strip
1. decrease row unit depth &/or rolling basket
pressure (should decrease wet soil disturbance)
