1 Workshop Instructions 152 Hydraulic ircuit iagrams W1521E1, These instructions apply from: 152(Std) I (S/) * * 152 I (S/) * * 152 I (S/) * * These Workshop Instructions for the 152 Vibratory Rollers show the hydraulic components, hosing and hydraulic circuit diagrams for the four different systems; traction, vibration, steering and brakes. The opening and working pressures of the various systems are also stated (however the working pressures may vary depending of working conditions), together with simple definitions of the hydraulic symbols. Reservation for alterations. rinted in Sweden
