Cleaning
Keeping the generator clean is an important part of good operation. If dirt buildup is not
removed, the generator will run hotter than normal and it’s life is reduced. The following are
general guidelines for cleaning.
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.)
5.
Inspect and clean all governor and carburetor linkages so they operate properly.
