Generator Maintenance

Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean and dry
environment where it will not be exposed to excessive dust,
dirt, moisture, or any corrosive vapors. Cooling air slots in
the generator must not become clogged with snow, leaves, or
any other foreign material.
NOTICE: DO NOT use water or other liquids to clean
generator. Liquids can enter engine fuel system, causing
poor performance and/or failure to occur. In addition, if liquid
enters generator through cooling air slots, some of the liquid
will be retained in voids and cracks of the rotor and stator
winding insulation. Liquid and dirt buildup on the generator
internal windings will eventually decrease the insulation
resistance of these windings.
Cleaning Fuel Strainer
The fuel strainer helps prevent debris from entering the fuel
system.
Clean the fuel strainer as follows:
1. Make sure generator is on a level surface.
2. Remove the fuel cap (A, Figure 3) and fuel strainer (B).
3. Wash fuel strainer in liquid detergent and water.
4. Wipe fuel strainer clean with a clean, dry cloth.
5. Carefully reinstall the fuel strainer and fuel cap.
