S2.12 Cleaning the 120 Volt AC Generator:
1. To clean the generator you must remove the generator cover (7 x 7/16” hex head screws,
lock washers and washers), and remove the generators mounting hardware. Please see
section 10 for further information on removal and reinstallation of the generator.
2. Remove the two Phillips head screws and plastic louvered panel that covers the capacitor
and clean the core using compressed air.
3. Continue the cleaning until no more debris is seen leaving the generator. The pulley on the
generator should be rotated so that all surfaces in the generators core are cleaned. Ensure
that you clean both the inlet and exhaust sides of the generator casing.
4. Do not use any liquid cleaners to perform this service.
5. If the generator windings are wet, ensure that the generator is completely dry before using
the generator. Operating the generator with wet windings will result in damage to the
insulation on the windings.
