HYDRAULIC SYSTEM:

System supply:
Two load-sensing axial piston pumps with variable displacement. The steering system always has priority.

Valves:
Double-acting 2-spool valve. The main valve is controlled by a 2-spool pilot valve.

Lift function:
The valve has three positions; raise, hold and lower position. Inductive/magnetic automatic boom kickout can be switched on and off and is adjustable to any position between maximum reach and full lifting height.

Tilt function:
The valve has three functions including rollback, hold and dump. Inductive/magnetic automatic tilt can be adjusted to the desired bucket angle.

Cylinders:
Double-acting cylinders for all functions.

Filter:
Full flow filtration through 10 micron (absolute) filter cartridge.
