R R (1) Apply SPECIAL MATERIALS (Material No. 05-005) with : - a spray gun and an air compressor, or with a brush.
R 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 (58.0150 psi), - the protective coat that gives protection must be 0.05 mm (0.0019 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,
R R (2) Let the cable dry between 1h30 and 2h00 (this time is related to the ambient temperature).
R R R (3) Apply COMMON GREASE (Material No. 04-004) on the rear THS control cables (between FR71 and the THS actuator) to prevent corrosion in this area.
