6.1 Disconnection of the hydrostatic travel
Before carrying out any hydrostatic travel
disconnecting operation, make sure that the
parking brake is applied and that the tow bar is
properly coupled to the towing vehicle.
- Apply the parking brake (2 fig. 1).
- Undo the heads of the limiters on the bypass valves (1 fig. 2)
situated under the transfer movement pump 2 or 3 turns,
using a 22 mm open-ended spanner.
- Release the parking brake only after connecting the
machine to the tractor’s towing bar.
Note: If the accumulator pressure is not
sufficient to release the parking brake,
red indicator light (1 fig. 4), unscrew the
ram rod's lock nut (1 fig. 3) using a
24 mm open-ended spanner in order to
release the disc brakes.
When the hydrostatic travel is disconnected,
the machine can be towed but the main brake
(1 fig. 1) is no longer active.
- Once towing is complete, tighten the heads of the limiters on
the bypass valves (1 fig. 2) as far as they will go using a
22 mm open-ended spanner.
