  • The safety-pin guide fitting (1)
  • The spring rod of the slide control handle (2)
  • The telescopic rod of the slide arming mechanism (3)
  • The hook of the interlock mechanism (4).
NOTE: You must use the correct type of grease. If you use lithium type grease as an alternative to the clay type grease, you must remove all the clay type grease from the component.
   (2) Apply a layer of Synthetic Ester base Grease-General Purpose Low Temp - (Material No.03HBD9) to the spring of the escape-slide control mechanism (5).
