(M) The function of the push buttons marked with (M) are memorized when stopping the excavator. This means that the controlled function recovers the previous state (on, off, 1/2, L/H, ...) before the machine had been turned off

Depressing the push button will successively: - turn on only the working floodlights on attachment, - turn on the optional installed auxiliary flood - turn on all the above floodlights, - switch off all the above floodlights.

S11

- Windshield washer

The electrical windshield washing device is activated by pushing the button S11 when the ignition is on. The detergent is sprayed and the windshield wipers operate as long as the button is pushed. The windshield wipers are turned off about 3 seconds after releasing the button.

S14

- Windshield wiper

Depressing the switch S14 (when the ignition is on)will successively:

1 turn on the windshield wiper in intermittent mode (the lighting diode I lights up)

2 turn on the windshield wiper in continuous (the lighting diode C lights up)

3 turn off the windshield wiper (both lighting diodes are extinguished)

Adjusting the delay time for intermittent mode via switch S14:

- Select the intermittent mode and keep the switch S14 depressed until the indicator lamp I starts blinking rapidly.

- Release the switch as soon as the blinking duration has reached the desired interval time (settings from 2 - 9 seconds).

S17 - Preselection of swing brake operating mode

With this button the swing brake can be switched, either in position "brake applied" or in position "brake in semiautomatic" (see on page 4.12).

Pushing the button shifts the brake from one operating mode into the other. With the brake applied, the red diode in the push button is on.

S18 - Overload warning device

This push button, alternately turns on and off the overload warning device. This device alerts the operator that the authorized lift capacity of the machine has been reached. It must be turned on before using the excavator for lifting operation. Also refer to page 7.5 to turn on the overload warning device.

S19 - Rotating device

An additional hydraulic circuit for rotating device operation is necessary to drive some specific equipments (such as rotating grapple, rotating bucket, rotating stick, quick change coupling, ...). The push button S19 turns on and off the control circuit of these specific equipments. With the control circuit turned on, the specific equipments can be actuated using the push buttons S5 on top of the left joystick handle.

When no rotating device is operated, the button S19 must be turned off. The button S19 is operative only if the safety lever is pushed down.

S20 - Low idle automatic (see page 4.5)

Via this push button the function "low idle automatic" is turned on, resp. off (the light diode in the button is on, resp. off).

Adjusting the time lag for low idle automatic via switch S20: The push button S20 also serves to adjust the time lag between the return to neutral of all joysticks and pedals and the automatic reduction to low idle of the engine RPM.

The adjustment is performed similar to the one described above for the windshield wiper pause time via button S14.

See page 4.11.

Depressing the push button will successively turn on and off the floodlights at the front of the uppercarriage, (Optional installation)

S41 - Beacon (Optional installation)

S56 - Pressure increase

When this function is turned on (light diode in the button is on), the forces on the working attachment are increased, and the movements of the machine become slow at the same time (load lifting operation,...).

S85 - Grapple operation

This button must be turned on each time when a grapple is operated.

S86 - Engine speed adjustment with mode preselection (see page 4.4 - 4.5)

The button S86 allows to preselect between four preadjusted engine RPM.

Depressing the button S86 causes to change from one mode into the next, in the order L, F, E, P, L, ... and so on.

L (Mode LIFT) = RPM stage 5

F (Mode FINE) = RPM stage 10

E (Mode ECO) = RPM stage 8

P (Mode POWER)= RPM stage 10

RPM stage 8 corresponds to the most favorable specific fuel consumption, RPM stage10 is full engine RPM.

In mode E or P, the Diesel engine is at the nominal power corresponding to the selected RPM stage. In the opposite, for modes L and F, the engine output is reduced by about 20%.

S228 - Engine RPM increase

See page 4.4

S229 - Engine RPM reduce

See page 4.4 (not used)

P4 - LED indicator for engine RPM

Via the LED bargraph indicator P4, the engine RPM is displayed. The complete RPM range is divided into 10 stages.
