Safety instructions and measures
Central control block
Text-module
Reason:
Bullet-List
● The pressure pipes of the front suspension between the central control block ZSB and the
suspension cylinders,
● the accumulators ASP1 and ASP2 on the central control block and
● the piped accumulator ZSP
are subject to a pressure of 200 bar even with the engine switched off and the suspension
lowered (=locked)!
Action:
The pressure has to be relieved manually before any repair is carried out or anything is released or
opened in this area.
Note:
The "Lock suspension / lower suspension" command has no effect!

Check:
Emptying of accumulator sounds like flowing liquid as oil temperature increases (scarcely audible in
winter).
Note and comparison:
For tractors without a central control block (e.g. Fav 500) it is still necessary to relieve pressure using
the "External power supply" method.
