Stopcock
Attention!
Before performing maintenance work between the tipper bridge and the
chassis, the stopcock for the tipper hydraulics must be closed.
This prevents accidental lowering of the tipper bridge.
A bridge support is required to perform maintenance with a raised tipper bridge.
If it is not available, the operator must provide a secure support; otherwise,
it is not permitted to perform maintenance work with the bridge raised.
See section 9.17
Use of the bridge support with a raised tipper bridge is mandatory during
maintenance.
