DROP IN THE SPEED OF THE MOTOR
Cause Solution
Too much oil. Drain oil.
Lack of fuel. Check fuel supply system:
- fuel filter, renew if necessary
- check fuel pump
- check fuel lines (bleed if necessary)
Lack of intake air. Check air intake paths.
Check and clean air filter (and intake muffler if installed).
Generator overloaded by too many load. Reduce the electrical load (switch off load).
Defective generator (windings, bearings, or other). Generator must be sent to manufacturer for repair of damaged bearings
or winding.
Damaged engine. Repair of bearing damage, etc., by Kubota-Service.
MOTOR SWITCHES ITSELF OFF
Cause Solution
Fuel solenoid valve or throttle shut solenoid is not switching off. Check wire connections to solenoid. Check valve functions as in the
„Inlet Fuel Solenoid Valve“ or in the throttle shut off solenoid sections.
Replace if necessary.
MOTOR STOPS BY ITSELF
Cause Solution
Lack of fuel. Check fuel supply system.
Excess heat in cooling system (thermo switch tripped)- lack of cooling
water. Is indicated on the remote control panel.
Check cooling water system flow: water pump, inlet water filter, extra
heat exchanger coolant flow.
Lack of oil (oil pressure sensor tripped). Check oil-level and if necessary top up.
Check motor's oil-pressure and have repaired by Kubota-Service if
necessary.
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 adjustment. 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 representative.
