CLASSIC 300D KUBOTA E-2E-2 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION Machine fails to hold the output (heat) consistently. 1. Rough or dirty commutator. 2. Brushes may be worn down to Limit. 3. Field circuit may have variable resistance connection or intermittent open circuit due to loose connection or broken wire. 4. Electrode lead or work lead connection may be poor. 5. Wrong grade of brushes may have been installed on generator. 6. Field rheostat may be making poor contact and overheating. If all recommended possible areas of misadjustment have been checked and the problem persists, Contact your local Lincoln Authorized Field Service Facility. Welder starts but fails to generate current. 1. Generator or exciter brushes may be loose or missing. 2. Exciter may not be operating. 3. Field circuit of generator or exciter may be open 4. Exciter may have lost excitation. 5. Series field and armature circuit may be open-circuited. Welding arc is loud and spatters excessively. 1. Current setting may be too high. 2. Polarity may be wrong. Welding current too great or too small compared to indication on the dial. 1. Exciter output low causing low output compared to dial indication. 2. Operating speed too low or too high. Arc continuously pops out. 1. “Current Range Selector” switch may be set at an intermediate position. CAUTION If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facilityfor technical troubleshooting assistance before you proceed. CLASSIC 300D KUBOTA E-3E-3 TROUBLESHOOTING ELECTRONIC IDLER TROUBLESHOOTING GUIDE With Idler Control Switch in the Auto Position, Engine Will Not Return to Low Idle in Approximately 15 Seconds After Welding and Auxiliary Loads are Removed Set Idler Control Switch to the Auto Position Check for Continuity through Idler Control Switch OpenClosed Check Voltage across Replace Idler Idler Control switch Control Switch 12 VDC 0 VDC Contact Kubota Replace current Engine Repair Sensing PCB Facility CAUTION If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facilityfor technical troubleshooting assistance before you proceed. CLASSIC 300D KUBOTA E-4E-4 TROUBLESHOOTING ELECTRONIC IDLER CONTROL TROUBLESHOOTING GUIDE With Idler Control Switch in the AUTO Position, Engine Will Not Pick Up Speed When: The Arc is Struck Check for loose or disconnected wire running between weld selector switch and output stud. Both 1. Check Idler circuit wiring. Possible Problems are wires from Current Sensing Board reversed at idler switch or wires connected incorrectly at Current Sensor Molex plug. 2. Check voltage across idler control switch. 12V 0V Replace Current Contact Kubota Sensing PCB Engine Repair Facility. Auxiliary Load 1. Load too small. Try load above 100 Watts. 2. Check for loose or disconnected wire running from black lead out of exciter to CB2 circuit breaker. CAUTION If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facilityfor technical troubleshooting assistance before you proceed. CLASSIC 300D KUBOTA E-5E-5 TROUBLESHOOTING Observe all Safety Guidelines detailed throughout this manual PROBLEMS (SYMPTOMS) POSSIBLE CAUSE RECOMMENDED COURSE OF ACTION Engine does not start. 1. Lack of fuel. 2. Air mixed in the fuel system. 3. Clogged fuel filter. 4. Irregular and faulty fuel supply (Injector pump trouble). 5. Glow plug not heated. 6. Clogged air cleaner. 7. No compression. 8. Engine protection light is ON. If all recommended possible areas of misadjustment have been checked and the problem persists, Contact your local Lincoln Authorized Field Service Facility. Engine does not turn over. 1. Faulty Ignition switch and or Injector pump solenoid. 2. Insufficient charging or complete discharge of the battery. 3. Improper viscosity of the lubricating oil. Irregular running of the engine. 1. Air mixed in the fuel system. 2. Uneven fuel injection (Faulty fuel injector pump). 3. Clogged fuel filter. 4. Defective governor. 5. Engine itself defective. Engine stops during operation and the Engine Protection light does notturn on. 1. Lack of fuel in the fuel tank. 2. Clogged fuel filter. 3. Air mixed in the fuel system. 4. Faulty function of the engine. Engine stops during operation and the Engine Protection light does turn on. See Light Code Diagnoses Attached. CAUTION If for any reason you do not understand the test procedures or are unable to perform the tests/repairs safely, contact your Local Lincoln Authorized Field Service Facilityfor technical troubleshooting assistance before you proceed.
