Section 8
Handling and Servicing
Do not use abrasive cleansers or cleaning pads on the
germanium window. Abrasive cleaning can damage the
sensor window coating.
Do not use any cleansers containing ammonia. Ammonia will
remove the sensor window coating.
Engine Compartment
Before cleaning the engine compartment, place a strip of tape on the
magneto vents to prevent any solvent from entering these units.
1. Place a large pan under the engine to catch waste.
2. Remove induction air filter and seal off induction system inlet.
3. With the engine cowling removed, spray or brush the engine with
solvent or a mixture of solvent and degreaser. In order to remove
especially heavy dirt and grease deposits, it may be necessary to
brush areas that were sprayed.
Do not spray solvent into the alternator, vacuum pump, starter,
or induction air intakes.
4. Allow the solvent to remain on the engine from 5 to 10 minutes.
Then rinse engine clean with additional solvent and allow it to dry.
Do not operate the engine until excess solvent has evaporated
or otherwise been removed.
5. Remove the protective tape from the magnetos.
6. Open induction system air inlet and install filter.
7. Lubricate in accordance with the Lubrication Chart.
Landing Gear
Before cleaning the landing gear, place a plastic cover or similar
material over the wheel and brake assembly.
1. Place a pan under the gear to catch waste.
2. Spray or brush the gear area with solvent or a mixture of solvent
and degreaser, as desired. Where heavy grease and dirt deposits
have collected, it may be necessary to brush areas that were
sprayed, in order to clean them.
