C. The forward fuselage and engine section should not be cleaned with water unless close
attention is made to avoid removal of lubricants and to avoid possible rusting of components
and hardware. A general purpose, non-corrosive cleaning agent is preferred in those areas.
D. Particular attention should be given to the attachments of the oil cooler, hopper, and engine
mounts.
E. Hopper cleaning should be accomplished at the end of each working day. A good commercial
detergent should be used and followed by a thorough flush with water. Leave the hopper door
and gate open for thorough drying.
An anti-static type of plastic cleaner, such as Mirror Glaze or equivalent, is recommended for best
cleaning. The side windshield are plastic and should not be cleaned with gasoline, alcohol, acetone,
lacquer thinner, or window cleaning spray. Those fluids will soften the plastic and cause crazing.
Avoid rubbing the plastic surface with a dry cloth, as that can cause scratches and build up an
electrical charge (static) which will attract dust particles. If scratches are visible after removing the
dust accumulation, finish the plastic with a quality grade of commercial wax. Apply the wax in a thin,
even coat and carefully buff out with a soft cloth. Do not buff or polish in one area for more than a
brief period of time. The heat generated by rubbing the surface may soften the plastic and may
produce visual distortion.
The middle section of the windshield is safety plate glass for better resistance to scratching. It is
enclosed in an aluminum frame.
Any damage to the paint on the tube structure should be restored before the tubes are to be re-
covered.
Hopper repair may be accomplished in accordance with the instructions contained in Section IX.
Fuel tank repair may be accomplished in accordance with the instructions contained in Section V.
The 24-volt batteries are installed in the engine compartment between the engine and firewall.
Access is gained to the batteries by removal of a cowling. Battery servicing involves adding distilled
water to maintain electrolyte level of 3/16 inch over the separators, checking the cable connections,
