Troubleshooting and Maintenance
Maintenance This manual contains only very minimal engine maintenance instructions. Refer to the engine manufacturer’s owner’s manual for specific engine maintenance instructions for your generator set. 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.Inspect and clean the battery posts and the associated battery cable terminals.
5.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.Replace the spark plug(s) as is recommended by the engine manufacturer.
5.Clean the cooling fins on the engine to keep the engine’s heat dissipation potential at it’s maximum.
6.Inspect and clean all governor and carburetor linkages so they operate properly.
7.Inspect the recoil starting rope for any damage and replace it if necessary (if applicable).
8.Clean the trash screen around the recoil starter or other cooling air intake. 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 will not keep perfect time when used on this generator.
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.)
