ADO Automatic dump function
If a lever is not moved for 3 seconds, this
function diverts the oil to the tank, thereby
preventing the oil from overheating. The next
lever movement stops the dumping and it func-
tions as normal.
ASC Automatic Speed Control
The ASC function automatically provides the
extra power by reducing the speed smoothly,
when working close to the rated capacity. When
the load decreases, normal speed is restored.
ADC Automatic Duty Control
The purpose of the ADC function is to increase
the lifting capacity by 10%.
The first boom pressure sensors indicate if there
is a positive or negative pressure on the first
boom.
Normal capacity
• If the first boom is pressed down, the sensors
indicate a negative pressure and the lifting
capacity is normal during the complete lifting
cycle.
Increased capacity (ADC mode)
• ADC lamps light up.
If the sensors indicate a positive pressure, the
lifting capacity is increased during the com-
plete lifting cycle.
PFD Pump flow distribution
When operating several functions simultaneously
the pump flow may not be sufficient. PFD will
now take over, reducing the speed of all operated
functions. Uncontrolled movements are thus
avoided, smooth simultaneous operation is
achieved.
