1.24 HYDRAULICS Accumulator(s) (11) The nitrogen charged accumulator(s) provide hydraulic pressure for efficient operation of the brakes under all pump load conditions. One accumulator is fitted for the single brake system and two are fitted for the dual brake system. The accumulator(s) are located in the chassis behind the cab assembly. Specifications Pre-charge pressure 41 bar (595 psi) Oil capacity 0.75 litre Pressure switch (12) The pressure switch illuminates a warning light in the cab when brake pressure drops to a critical level. The pressure switch is located adjacent to the accumulator(s) (11) behind of the cab structure, forward of the rear axle.
Specification Operating pressure 116 bar (1682 psi) falling Pressure switch (transmission dump) (13) When the transmission dump selector switch in the cab is operated the pressure switch will disconnect transmission when the brakes are applied. The pressure switch is located adjacent to the transmission drop box, above the drive shaft. Specification Operating pressure 15 bar (217 psi) rising
