7.4.7 Motor does not achieve enough speed during starting process
7.4.8 Motor runs unsteady
7.4.9 Motor speed drops
7.4.10 Motor runs in off position
Glow-plugs not working correctly. Check glow plugs and heating time.
Too much air in fuel lines. Test fuel system for leakage. Bleed air from fuel system (refer to section
"Bleeding Air from Fuel System").
Fuel-filter blocked. Replace fuel filter.
Cause Solution
Starter battery voltage insufficient. Check battery.
Damaged bearing(s) piston (seized). Repairs need to be carried out by Kubota-Service. (refer to Kubota mo-
tor-manual)
Cooling water in combustion chamber. 1. Turn generator "OFF" at control panel.
2. Remove the glow plug (see Kubota-manual).
3. Rotate the motor by hand carefully.
4. Check if there is water in the oil and change both oil and filter if neces-
sary.
5. Determine cause for excess water in the combustion chamber. The
excess water can be caused by a defective air vent in the cooling water
system, which should be checked and cleaned, or replaced if faulty.
Cause Solution
Disruption in the area of the injection systems’ automatic advance. Repair / Check the automatic advance via the motor service.
Air in the fuel system. Ventilate the fuel system.
Cause Solution
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).
Generator overloaded by over-energizing. Check that the proper capacitor type is installed and that they are con-
nected correctly.
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.
Cause Solution
Fuel inlet solenoid valve or throttle shut solenoid is not switching off. Check wire connections to solenoid. Check valve functions as in the
"Fuel Solenoid Valve" or in the trottle shut off solenoid sections. Replace
if necessary.
