SAFETY CIRCUIT 5.10 General Information Seat switch The loader is equipped with 3 inter - connected safety switches. These 3 switches operate 2 electric solenoid controlled lock devices. One (1) solenoid coil on the hydraulic brake valve (fig. C2364), one (1) pair of sole- noid coils on the hydraulic control valve (fig. C1514) Failure of any one (1) of these switches will prevent the operation of the solenoid coils and loader functions. All 3 must be hooked up, functioning and, if applicable, adjust- ed correctly. Connector The bottom of the operators seat is equipped with a pres- sure sensitive switch.
The operator must be in the seat to close the switch and release the parking brake and unlock the control valve functions. (fig. C807) No adjustments required. When removing and replacing the seat, be sure to disconnect the wire connector and not to pinch the wires under the seat plate. C807 Seat belt latch & switch Harness plugs The seat belt assembly is equipped with a safety switch. The operator must have the seat belt fastened around them in order to close the switch and allow the parking brake to release and the control valve to function. (fig. C1816) No adjustments required. 5 The restraint bar is equipped with a dual function safety switch. (fig.
C2027) With the restraint bar in the raised position, the parking brake is activated, the control valve functions are locked and the activation indicator lights are illuminated on the dash panel. Lowering the restraint bar releases the parking brake by energizing the solenoid coil to release the hydraulic brake valve lock (fig. C2362), turns off the indicator lights in the dash panel and releases the locks in the main control valve by energizing the solenoid coils. (fig. C1514). The restraint bar must be in the lowered position for the control functions to operate. The switch must contact the restraint bar when in the lowered position.
