Hydraulic Circuit DiagramsW1063EN2, September 2000
These instructions apply from:CA 132 PIN (S/N) *21620331*
These Workshop Instructions for the CP 132 Pneumatic Tire Roller show the hydraulic components, hosing and hydraulic circuit diagrams
for the four different systems; traction, drain, 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.
