(1) All critical unpainted metal surfaces must be protected during shipment.
Oil or grease covered in the lubrication section may be used for this
purpose but it is effective for only a few days. Equipment protected in
this manner must be watched for signs of corrosion. Preservatives
selection will be such that their application, use or removal will not
damage the surface to which they are applied.
(2) Coat lower landing leg, chassis, frame, exterior hardware and suspension
system with corrosion preventive compound.
(3) Spray data plates with a thin coating of ignition insulation compound.
Control overspray to avoid coating adjacent surfaces.
(4) Cover all exterior reflectors and lights with tape.

Maintenance After Operation on Unusual
It is very important that approved maintenance
procedures be followed. FM 9-207 contains general
information which is specifically applicable to this
materiel as well as all other materiel. It must be
considered an essential part of this technical manual,
not merely an explanatory supplement to it.
a. The importance of maintenance must be impressed on all concerned.
Maintenance of mechanical equipment in extreme cold is exceptionally difficult in
the field. Even shop maintenance cannot be completed with normal speed because
equipment must be allowed to thaw out and warm up before the mechanic can make
satisfactory repairs. In the field, maintenance must be undertaken under the most
difficult of conditions. Bare hands stick to cold metal. Fuel in contact with the
hands results in supercooling due to evaporation, and hands can be painfully frozen
in a matter of minutes. Engine oils, except subzero grade, are unpourable at
temperatures below -40F. Ordinary greases become as solid as cold butter.
b. These difficulties increase time required to perform maintenance. At
temperatures below -40F., maintenance requires up to five times the normal amount
