3.4.10Swivelling uppercarriage

Caution!

All machines are equipped with the PCSA control as standard. On special request, the machine can be fitted with a different control system (e.g. LIEBHERR control). For such machines, observe the instructions in the respective separate operating manual.

The joystick functions described here apply only to the PCSA control

The uppercarriage is swivelled by means of the left joystick.

3-70 Swivelling uppercarriage

Move the joystick to the left c

The uppercarriage is swivelled to the left. Move the joystick to the right d

The uppercarriage is swivelled to the right.

If required, also adjust the sensitivity of the slewing gear (see chapter "Display", Torque Slew menu):

3.4.11Halting uppercarriage

The uppercarriage can be hydraulically slowed down in its movement and halted. The mechanical slewing gear brake allows the operator to secure the uppercarriage in any desired position.

Applying hydraulic brake:

Move the left joystick 4 to its neutral position. The uppercarriage is slowed down hydraulically. Move the left joystick 4 in the opposite direction. The uppercarriage is stopped with the maximum hydraulic force.

Mechanical slewing gear brake:

Caution!

The mechanical slewing gear brake might be damaged, if it is applied while the uppercarriage is moving.

Therefore apply the slewing gear brake only when the uppercarriage is standing still.

Press the switch S17. Slewing gear brake is applied. The LED in the switch is on.

Press the switch S17 again.

Slewing gear brake is released. The LED indicator in the switch is off.

Checking of the mechanical slewing gear brake: Ensure that the uppercarriage is standing still.

Press the switch S17

Slewing gear brake is applied. The LED in the switch is on. Move the left joystick 4 to the right and then to the left stop. The uppercarriage must not move. The slewing gear brake is working properly.

Positioning slewing brake (optional equipment):

The positioning slewing brake is used for the progressive and precise slowing down of the uppercarriage.

Note!

Increased wear.

Do not use the positing slewing brake as a working brake, but only for special halting and parking manoeuvres of the slewing gear.

The uppercarriage should normally be stopped with the hydraulic brake.

Actuate the pedal 10; if required, carefully slow down the uppercarriage. The uppercarriage is held in the desired position.

3.4.12Adjustment of tool attachment

The machine can operate a range of tool attachments (additional consumers) with various pressure and flow rate settings. The respective selections are made in the operator's menu (see "Tool Control" menu).

Caution!

If an incorrect operating mode is chosen, the tool attachment might be damaged or its functions might be restricted.

Make sure that you have all the necessary information regarding the technical data of the tool attachment.

Use the tool attachment exclusively with the prescribed settings (Tool option).

In the operator's menu, select the pressure and flow settings required for the tool attachment you wish to operate (see chapter "Tool option").

3.4.13Operation of attachment (optional equipment)

Caution!

Incorrect pressure or flow reduction preselections may result in damage to the attachment (e.g. hydraulic hammer) or restricted functionality (e.g. boom regulating cylinder).

Danger!

If a large or wide tool attachment (e.g. grapple) is swung near the operator's cab, it might collide with the cab or even break through it, causing danger to the machine operator.

Select the pressure and flow settings required for the respective tool attachment on the display (see chapter "Display", Tool Option menu).

Press the switch S241 to activate the tool attachment: Press the switch S241 down.

The tool attachment is activated. The indicator light in the switch is on.

Press the foot pedal k down.

The scrap shears or the sorting grapple are closed. - alternatively -

The hydraulic hammer is actuated. Press the foot pedal m down.

The scrap shears or the sorting grapple are opened.

Press the switch S241 up.

The tool attachment is deactivated. The indicator light in the switch is off.

When the tool attachment is operated, a separate symbol (black dot) is shown beside the selected option (see Fig. 3-74).

3.4.14Changeover of the control system (optional equipment)

On request, the machine can be equipped with a changeover unit of the control system kit. With this unit, it is possible to change the "tilt cylinder actuation" (e and f) over to the actuation of the tool (m and k).

Select the pressure and flow settings required for the respective tool on the display (see chapter "Display", Tool Control menu).

Changing over control:

To change over, turn the key switch S405

Turn the key switch S405 to position 1 The indicator light H322 is on. The control functions are changed over. Turn the key switch S405 back to position 0 The indicator light H322 is off. The control system is changed back to its initial function.

FunctionS405 off (0)S405 on (1)

Bucket tilt function / grapple e + fm + k

Working tool m + ke + f

Operate working tool and bucket tilt function (grapple) according to the chosen changeover.

Note!

The switchover is only available for working tools, the bucket tilt function and the grapple. The boom is still operated by means of the pedals m and k

Use this menu to activate the pedals for boom adjustment while an attachment (e.g. mower rake) is operated.

Setting values:

For a description, see chapter "Operator's menu", submenu "Y268 on/off".

3.4.15Operating attachment tool (mini joystick control, optional equipment)

Danger!

The working attachment can cause serious or even fatal injury to persons. Ensure that no persons are standing inside the danger zone of the machine. It is strictly forbidden to guide the attachment tool by hand.

Danger!

If a large or wide attachment tool (e.g. grapple) is swivelled towards the operator's cab, it might collide with the cab or even break through it, causing danger to the machine operator.

Always keep a safe distance between the moving attachment tool and the operator's cab.

3.4.15.1Working functions

Mini joystick, operating attachment tool

The working functions of the attachment tool are controlled by means of a mini joystick located on the right joystick.

The further the mini joystick is moved in a particular direction, the faster the attachment tool is moved.

In this control mode, it is not necessary to activate the attachment tool with a separate switch as these functions are automatically activated when the servo control is switched on.
