A. Cleaning of the Cables
(1) Soak a cloth with Non Aqueous Cleaner-- Petroleum Based - (Material No.08BBB1) and remove the unwanted material. Clean the surface of the cable.

NOTE: Remove the unwanted material from the cloth to make sure that it does not go into the cable core. This removes the lubricant around each strand.

(2) Fully dry the cables.

B. Protection of the Cables
(1) Apply Corrosion Preventive Compound-- Soft Film System (Material No.12AGC2) with a GUN - SPRAY or with a BRUSH - BRISTLED on the full length of the cable.

NOTE: These conditions are applicable for each procedure:

The ambient temperature must be between 5 deg.C (41.00 deg.F) and 35 deg.C (95.00 deg.F),
If you use a spray gun, the air pressure must be at least 4 bar (58.0151 psi),
The protective coat that gives protection must be 0.05 mm (0.0020 in.) thick,
The protective film must be even along the length of the cable. There must be no unwanted thickness caused by drops or runs.

(2) Let the cable dry between 1h30 and 2h00 (this time is related to the ambient temperature).
(3) To prevent corrosion, apply Synthetic Oil base Grease-General Purpose Lithium Thickened Low Temp. - (Material No.03GBC1) on:

The rear Trimmable Horizontal Stabilizer (THS) control-cables (between FR71 and the THS actuator)
The rear rudder control-cables (between FR71 and the quadrant at FR75).
