Control and operation

This push button is mounted serially.

The pause time of the intermittent mode of the cab roof window wiper can be adjusted by turning this button. (The window wiper is switched on and off using the touch S218).

If the touch S98 is actuated, the pressure protection value for lowering the attachment (circuit for retraction of the boom cylinders) is reduced, so to limit the possible downward thrust exerted by the working attachment onto the materials to be dug out.

This safety device must be turned on, as an example, when unloading a boat or a barge, so to avoid damage to its bottom.

Thanks to this switch, the operator can control the movement of the additional user of an add on kit AHS either using the double pedal destined for this purpose (key switch in position "pedal")., or via the right joystick (key switch in position "joystick").

See also "Commutation of the control for the user of add on kit AHS" in this chapter.

On machines fitted with the special equipment "cooler fan reversible", the direction of revolution of the cooler fan can be inverted while actuating the push button S160. In some particular working conditions, this inversion of the direction of the fan rotation allows an easy cleaning of the radiator core and of suction area of the fan.

See also the section "Reversible cooler fan (Optional equipment)" in the chapter "maintenance".

Option on the High-Rise or High-Pedestral machines. See "Access to the cab".

N When Operating A Super Long Working Attachment

When using a long reach attachment (super long working attachment with a smaller digging tool), this device allows to limit the working pumps oil flows to a value admissible for all the hydraulic cylinders of the working attachment.

Turn the key switch S168 to the right, in po movements of the working attachment.

Draulically Adjustable Cab

See the section "Hydraulically adjustable cab (option)" in this chapter.

When the ignition key is in contact position, pressing the switch S218 activates the cab roof window wiper.

This touch switch on and off the additional floodlight.

This touch switch on and off the additional floodlight.

S357 Touch / Lifting the attachment while the grapple is being closed

With this function, the working attachment is lifted slightly while the grapple is being closed. This reduces the risk of damage to the surface on which the grapple is used. Example: Protection of loading areas, ship bottoms and similar surfaces.

Note! This function is an auxiliary tool designed to assist the machine operator. Even if the function is activated, the surface can still be damaged due to lack of care.

The button turns on the electric cab roof window washer system. Washer fluid will be sprayed to the window and the cab roof window wiper will be actuated as long as the push button S362 is depressed.

S422 - Radio muting

See the section "Safety access to electric machines for industrial applications with self-stabilising tower superstructure" in this chapter.

The additional standstill heater is only working when the main supply circuit is open. Its performance is 1,1 kW.

Model with button ON / OFF / AUTO

Two modes of operation are possible:

/off the additional standstill heater independently of the programmation of the automatic mode and day slot.

Only an authorized person can change the programmation of the additional stanstill heater.

Model with control unit

See the supplier manual at the end of this operating manual.

Specific controls for cab movements

.. of a cab on a hoist frame with double parallelogram copyright by

This control light lights up to indicate that the swing movements of the uppercarriage have been cut off, due to a risk of collision between the bottom of the cab and the undercarriage.

See also "Swing movements shut off", in the heading "Cab adjustable on hoist frame with double parallelogram" further in this chapter.

On the machines fitted with the optionally installed hoist frame with double parallelogram, the joystick U45 (see below) is made alive via the touch S370. The cab position adjusting movements directed by the joystick U45 are possible only as long as the touch S370 is held depressed.

Once the cab has arrived in its lowest secure level the cab lowering movements are automatically cut off for safety reasons. The operator can then continue moving the cab down, for example to bring it in the access position, near the soil, while simultaneously keeping the touch S477 depressed.

See also "Safety cut off of cab lowering movements", in the heading "Cab adjustable on hoist frame with double parallelogram" further in this chapter.

This joystick controls the up and downwards movements of the cab side and uppercarriage side elements of the double parallelogram cab elevation.

3.2Access and equipment of the cab

3.2.1Access to the cab

Climbing up to and descending from the cab

Caution!

Climbing up to and descending from the cab incorrectly could lead to injury. To acceed to the machine, exclusively use the steps, ladders and handrails destined for climbing up and leaving the machine.

Fig. 3-31 Climbing up to the uppercarriage them from mud, oil, grease, ice, snow or any other obstacles. ely close off the chain giving access to the footbridge. any person to try to accede to the excavator during operation without getting the permission by the driver uppercarriage during operation.. the machine, you must make sure the machine is parked on a flat, firm and level ground and the ladders and steps are aligned on upper and undercarriage. ay and guard rails are within ISO 2867 recommendations.

The person wishing to accede to the excavator must first give signal to the driver on, the driver must align the upper and the undercarriage, lower the attachment to the ground, get in work - or entrance position, lift the safety lever, leave the cab and open the access chain The person is now allowed to approach and to climb up the machine.

The ladder and catwalk lightening (option) is actuated, via the touch S127, from outside (bottom of the ladder) and from the cabine (right console).
