CARPETS.
Use a small whisk broom or vacuum to remove dirt. For soiled spots, use a non-inflammable dry-cleaning
fluid.
ENGINE COMPARTMENT.
Before cleaning the engine compartment, place strips of tape on the magneto vents to prevent any solvent from
entering these units.
1. Place a pan under the engine to catch waste.
— CAUTION —
DO NOT SPRAY SOLVENT INTO THE ALTERNATOR, STARTER, VACUUM
PUMP, AIR INTAKE AND ALTERNATE AIR INLETS.
2. With the engine cowling removed, spray or brush the engine with solvent or a mixture of solvent and
degreaser, as desired. It may be necessary to brush areas that were sprayed where heavy grease and dirt
deposits have collected in order to clean them.
3. Allow the solvent to remain on the engine from five to ten minutes, then rinse the engine clean with
additional solvent and allow to dry.
— CAUTION —
DO NOT OPERATE ENGINE UNTIL EXCESS SOLVENT HAS
EVAPORATED OR OTHERWISE BEEN REMOVED.
4. Remove the protective covers from the magnetos.
5. Lubricate controls, bearing surfaces, etc., per Lubrication Charts. (Refer to Chapter 12)
FUEL SYSTEM.
1. To flush the fuel tanks and selector valve, disconnect the fuel line at the carburetor.
2. Select a fuel tank, turn on the electric fuel pump and flush fuel through the system until it is determined
there is no dirt and foreign matter in the fuel valve or tank. During this operation, agitation of the fuel
within the tank will help pick up and remove any dirt.
3. Repeat this procedure for each tank.
4. When all tanks are flushed, clean all filters.
