pressures present in the circuits of the machine.
2 - Press the hammer control pedal to release the residual pressure present in the hammer delivery pipe.
3 - Slowly loosen the hydraulic oil filling cap to release the residual pressure from the tank.
4 - Disconnect the hammer feeding and draining pipes.
5 - Fit the sealing plugs of the rapid couplings.
6 - Disconnect the hammer from the mechanical constraints, as described in “3.13.4 CHANGING THE BUCKET”.
