Dispose of suspension strut. - OS32.25-P-0122-01N

      REFER TO FORMS
DANGER Risk of injury  to skin or eyes from hydraulic fluid spraying out under pressure. Risk of poisoning  from swallowing hydraulic fluid. Depressurize the hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses. AS00.00-Z-0013-01A
DANGER Risk of injury  caused by drilling gas-filled assemblies or components (noncombustible gases) Wear safety glasses and a face mask. AS00.00-Z-0006-01A

IMPORTANT Observe regulations governing disposal of hydraulic fluid.

  2. Detach hydraulic line (40f) carefully from the suspension strut (due to residual pressure).
  3. Empty the hydraulic line (40f); to do this, press on the nipple (arrow) of the quick-release coupling and dispose of the hydraulic line (40f).
