SOOTY, BLACK EXHAUST
Cause
Solution
Generator is overloaded.
Check electrical load and switch off unnecessary load.
Insufficient intake air.
Check intake air filter; clean if necessary.
Fuel injector nozzles faulty.
Replace injector nozzles.
Valve clearance incorrect.
Readjust valve clearance to correct value (refer to
Kubota-manual).
Poor fuel quality.
Use better quality diesel (recommended: 2-D Diesel).
Poor combustion.
Incorrect AFR (air/fuel ratio) due to motor timing adjust-
ment. Have motor serviced by Kubota.
Low compression pressure.
See Kubota motor manual.
GENERATOR MUST BE SHUT OFF IMMEDIATELY IF:
Cause
Solution
- motor rpm suddenly rises or drops
- unusual noise comes from genset
- exhaust colour suddenly becomes dark
- motor overheats
- oil pressure drops, oil light suddenly flashes
Refer to respective section of manual and if necessary,
have repaired by Kubota-Service, or Panda represen-
tative.
TROUBLESHOOTING VCS SYSTEM
Cause
Solution
Actuator does not move.
Check voltage supply and wire connections to actuator.
Motor connected?
Check connection to VCS.
Actuator sets throttle too high or too low.
Check that the wires to the actuator are connected pro-
perly (±).
Check connection to VCS.
If the VCS electronics are faulty, the generator can still run by over-riding the system. To override the VCS, dis-
connect the plug and jumper the contacts.
Loosen the connecting rods motor from the injection pump regulator and turn screw to a max. voltage of 33V.
