Precautions to be taken.
Work with care to avoid entry of polluting particles.
NOTE:Correct operation of the system requires the LDSfluid and the hydraulic components
to be perfectly clean.
Check:
- The level of the LDSfluid (see procedure: drain-fill-bleed the suspension circuit).
- The condition of the piping and unions.
Using the tools.
Prepare the checking assembly [3], [4]and [5].
Remove the bracket (1).
Clamp the pipe at "a", using tool [2].
