Cab
Instrumentation: All important information
is centrally located in the operator's fi eld
of vision. Display for Contronic monitoring
system. Heater and defroster: Heater coil
with filtered fresh air and fan with four
speeds. Defroster vents for all window areas.
Operator's seat: Operator's seat with adjustable
suspension and retractable seatbelt.

Hydraulic system
System supply: Two load-sensing axial piston
pumps with variable displacement. The
steering function always has priority from
one of the pumps. Valves: Double-acting
2-spool valve. The main valve is controlled by
a 2-spool pilot valve. Lift function: The valve
has four positions; raise, hold, lower and
fl oat 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; rollback,
hold and dump. Inductive/magnetic
automatic tilt can be adjusted to the
desired bucket angle. Cylinders: Doubleacting
cylinders for all functions. Filter: Full
fl ow fi ltration through 20 micron (absolute)
fi lter cartridge.

Specifi cations
BUCKET SELECTION CHART
The choice of bucket is determined by the density of the material and the
expected bucket fi ll factor. The actual bucket volume is often larger than the rated
capacity, due to the TP Linkage features:
• Open bucket design.
• Very good roll back in all positions.
• Good bucket fi ll performance. The below example and table
are intended for Standard boom. Example: Sand and gravel. Fill factor ~ 105%.
Density 1,65 t/m3. Result: The 3,3 m3 bucket carries 3,5 m3. For optimum
stability always consult the bucket selection chart.
