Subtask 57-45-11-110-050-A
A. Cleaning and Preparation of Slat 4 Surfaces
WARNING: DO NOT GET THE FLUID ON YOUR SKIN OR IN YOUR EYES. IF YOU DO:
  • FLUSH IT AWAY WITH CLEAN WATER
  • GET MEDICAL AID.
   (1) Cleaning
     (a) Use a Textile-Lint free Cotton - (Material No.14SBA1) , made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the grease from the slat surface:
  • Apply the Non Aqueous Cleaner-General - - (Material No.08BAA9) to the cloth, not the cloth to the Non Aqueous Cleaner-General - - (Material No.08BAA9) . This will prevent the transfer of contamination.
  • Carefully clean a small area at a time and remove the Non Aqueous Cleaner-General - - (Material No.08BAA9) before it becomes dry. Use a new Textile-Lint free Cotton - (Material No.14SBA1) frequently to make sure that the dirt is not put back on the surface.
  • If necessary, use a brush to clean out the holes and edges.
     (b) Clean the slat surface again, where there is contamination remaining.
     (c) When the area is clean, flush with clean water.
     (d) Carefully dry the area with a new, dry Textile-Lint free Cotton - (Material No.14SBA1) .
   (2) Preparation for Painting
     (a) If the finish paint or primer layers are damaged, do a repair (Ref. AMM TASK 51-75-12-300-001).
     (b) If necessary, carefully smooth the surface to be painted with a fine-grade PAD - ABRASIVE and Non Aqueous Cleaner-General - - (Material No.08BAA9) . Make sure that the primer layer does not show.
     (c) Remove the abrasive grit and use a Textile-Lint free Cotton - (Material No.14SBA1) , made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the surface. Clean off the Non Aqueous Cleaner-General - - (Material No.08BAA9) before it becomes dry. Make sure that you do not touch the surface with your hand.
