ELECTROVACUUMATIC CONTROL SYSTEM
ELECTROV ACUUMATIC CONTROL ADJUSTMENT
Suspend the vehicle on an elevator.
Dismount the fixing lock pin of the connection bolt (8) between the capsule axle and the
control lever (6), then remove the bolt from its place.
Rotate the front right wheel and set the positions coupled-uncoupled acting upon the front
transmission control axle. The front transmissi o n control axle stroke = 11,5 mm.
Operate the front transmission axle (7) in the position uncoupled, then rotate the threaded
