Hydraulic system<br />
System supply: Two load-sensing axial piston pumps with variable displacement.<br />
The steering function always has priority. Valves: Double-acting 2-spool valve.<br />
The main valve is controlled by a 2-spool pilot valve. Lift function: The valve has<br />
four positions; lift, hold, lower, and float position. Inductive/magnetic automatic<br />
boom kick-out can be switched on and off and is adjustable to any position<br />
between maximum reach and full lifting height. Tilt function: The valve has three<br />
functions: rollback, hold and dump. Inductive/magnetic automatic tilt can be<br />
adjusted to the desired bucket angle. Cylinders: Double-acting cylinders for all<br />
functions. Filter: Full-flow filtration through 20 micron (absolute) filter cartridge.<br />

Steering system<br />
Steering system: Load-sensing hydrostatic articulated steering. System<br />
supply: The steering system has priority feed from a load-sensing axial piston<br />
pump with variable displacement. Steering cylinders: Two double-acting<br />
cylinders.<br />
