Manual Extract:

Located near the right-hand control lever, it has a front face covered with a silk-screened plastic film, an electronic circuit board with six momentary-action push-buttons, eight LED type indicator lamps, electronic components and a connector.
The functions of the control panel can be classified under four modes:

– The “Work” mode, consisting of the following push-buttons: “FINE” 1580 to 1620 rpm (low flow work, handling), “ECO” 1880 to 1920 rpm (economical, digging) and “MAX” 2180 to 2220 rpm (maximum power, hard work).
– The “Idle” mode consisting of the following push-buttons: “LOW” 900 to 1000 rpm (low idle) and “AUTO” 1180 to 1220 rpm (automatic idle).
– The “Travel” mode (two-speed excavators only) has two indicator lamps: “POSITION 1” (low speed) and “POSITION 2” (high speed).
– The “Pre-heat” mode has an indicator lamp: a flashing lamp shows the machine has not yet reached its normal operating temperature. When that lamp goes out the machine is ready to work.
