HYDRO-PNEUMATIC DRAWBAR
- *OPTIONAL SEMI-TRAILERS HMB
Possible Anomalies:
•
The drawbar cylinders are lowered! - Hydraulic system leak. Fill up the system until re-opening of the suspension
cylinders (while the vehicle is unloaded). Stop when the value indicated on the pressure gauge is equal to the pre-load
value stated on the accumulator or self-adhesive label.”
•
The drawbar does not act as suspension (very rigid) – Check if the pre-load value is higher than the value indicated on
the accumulator when empty (no load). If it is, oil should be removed from the circuit to achieve the pre-load value.
