Any maintenance instructions or recommendations in the engine owner’s manual take precedence over any of the following general recommendations. General: 1. Inspect the fuel system for leaks. Replace all defective components immediately. 2. Inspect and replace any fuel line that shows signs of deterioration. 3. Inspect all the fuel clamps to ensure they are tight. 4. Make sure the fuel cap fits snugly on the fuel tank and that the fuel tank contains no leaks. 5. Inspect and clean the battery posts and the associated battery cable terminals. 6. Inspect the external wire cables and connectors used with the generator set for cuts, fraying, or loose connections. Repair or replace any problems prior to using the unit. Engine: 1. Clean and/or replace any fuel, oil, and/or air filters per the engine manufacturers’ guidelines. 2. Check oil level regularly; at least every 5 to 8 operating hours. Maintain the proper oil level. 3. Change the oil as is recommended in the engine manufacturer’s owner’s manual. 4. Clean the cooling fins on the engine to keep the engine’s heat dissipation potential at it’s maximum. 5. Inspect and clean all governor and fuel supply linkages so they operate properly. Alternator: ( also called Generator End) This generator set must be run at its proper speed to obtain the correct electrical power at its output. All engines have a tendency to slow down when a load is applied to it. The engine governor is designed to hold the operating speed as nearly constant as possible. When the electrical load is increased, the engine is more heavily loaded and engine speed drops slightly. This slight decrease in engine speed results in a slight decrease in generator voltage and frequency output. This voltage and frequency variation has no appreciable effect in the operation of motors, lights, and most appliances and tools. However, timing devices and clocks may not keep perfect time. 1. Clean the generator set and remove any and all dust, dirt, or other foreign material. 2. Inspect and clean the cooling air intake and exhaust louvers of the generator end. Make sure they are clean. Remove dirt or any buildup that may restrict the cooling air flow. 3. Clean the generator set and its components with a damp cloth or sponge. Never use a water hose or pressure washer as this may damage electrical components. 4. Inspect and replace any control panel components that are broken or not working properly (receptacles, circuit breakers, switches, etc.) MN2417 Troubleshooting and Maintenance 5-1 Problems and Solutions Some of the more common problems are listed in Table 5-1. This information is intended to be a check or verification that simple causes can be located and fixed. It is not an exhaustive “how to” for all types of problems. Procedures that require in depth knowledge or skills (like flashing the field) should be referred to an authorized service department. Table 5-1 Troubleshooting Guide Problem Possible Cause Remedy Engine will not start No fuel. Check that fuel valves are ON. Check fuel level in fuel tank. Restricted air flow. Check/replace air filter. Damaged glow plug Check/replace glow plug(s). Check that engine switch is in Start position. Engine will not crank Dead battery. Remove battery and trickle charge or replace with new battery. Never Jump Start. Engine starts but will not run smoothly Fuel or ignition problem Refer to engine manual. Engine overheats Output voltage varies Low Voltage (0.15 VAC output) Excessive load Debris or dirt buildup on engine Low Coolant Level Irregular speed Fluctuating speed Loose terminal or load connections Defective alternator bearing (uneven air gap) Bad Voltmeter Bad/Open Circuit Breaker/Fuse Bad Connection Loss of Residual Magnetism Bad Voltage Selector Switch Bad Stator Windings Remove one or more electrical loads. Remove debris. Clean engine surfaces to allow cooling. Replenish coolant Check engine for malfunction or load for fluctuation Stabilize load. The addition of a lamp load (resistance load) may compensate partially for load changes caused by intermittent motor operation. Do not overload. Verify all connections are proper and check tighness torque of terminals. Replace worn bearing Measure the voltage across the voltage meter with an accurate voltmeter to verify. Check continuity across Breaker/Fuse. Replace if defective. Check wiring including grounds, crimps and connection points. Repair defects. The generator needs to be flashed. Contact service center to perform this procedure. Replace switch, contact service center to perform this procedure. Contact service center to perform this procedure.
