3.4.12Operating 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.

3.4.12.1Working functions

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.

Example: hydraulic hammer

Push the mini joystick to the left 1 The hydraulic hammer is operated.

Example: sorting grapple, scrap shears

Push the mini joystick to the left 1 The attachment tool closes.

Push the mini joystick to the right 2 The attachment tool opens.

3.4.12.2Rotating and adjusting

1 Rotator (e.g. for rotating grapple)

2 Lock bolts of a hydraulic quick-change adapter system

3 Swivelling ditch cleaning bucket

L/R Direction of movement

The mini joystick on the left joystick is used to rotate or change the attachment tool. The rotating function corresponds to the "rotate grapple" function used for grapples and other attachment tools.

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.

Push mini joystick to the left L

The attachment tool turn s (swivels) to the left. The lock bolts are extended.

Push the mini joystick to the right R The attachment tool turn s (swivels) to the right. The lock bolts are retracted.

3.4.13Changeover of joystick control (optional equipment)

3-79 Changeover of control

Depending on the selected mode, the attachment tool is operated with the mini joystick (movement 1 and 2) or with the joystick (movement e and f).

To change from one control mode to the other, turn the key switch S405 in the right control console.

Turn the key switch S405 to position 1. The indicator light H322 is on. Control changeover is activated.

If the control is changed over, the tilting system is disabled.

Operate the attachment tool according to the current control mode.

3.4.14Super Finish (optional equipment)

With the Super Finish function, the movement of the attachment can be slowed down, so that tasks can be carried out with greater precision. This is achieved by a flow reduction, which slows down the movement of the machine proportionally.

Super Finish (SF) can be activated by means of the rocker switch S382 in the left joystick.

Press the rocker switch down. Super Finish is activated.

The Super Finish (SF) indicator light is on.

Operate the attachment and check the working speed.

Modified operation of Super Finish (optional equipment)

With the Super Finish function, the movement of the attachment can be slowed down, so that tasks can be carried out with greater precision. This is achieved by a flow reduction, which slows down the movement of the machine proportionally.

Press the switch S382 down.

Super Finish is activated. The Super Finish (SF) indicator light is on. Operate the attachment and check the working speed.

Press the switch S382 up. Super Finish is deactivated. The Super Finish (SF) indicator light is off. Adjust the flow reduction settings, if necessary (see chapter "Operator's menu", SFFlow menu).

3.4.16Stroke limitation (optional equipment)

The stroke limitation determines the maximum permissible working height of the working attachment. Stroke limitation might be required on sites where the vertical working area is restricted by obstacles (e.g. overhead power lines).

When activated, the stroke limitation function stops the upward movement of the working attachment as soon as the maximum permissible working height is reached.

The maximum permissible working height can only be set correctly in connection with a LIEBHERR attachment whose factory settings are correct. After a change or adjustment to the LIEBHERR working equipment, the stroke limitation settings must be re-adjusted by LIEBHERR.

If the machine has been moved to a new location, the stroke limitation settings must be checked and adjusted, if necessary.

Danger!

The stroke limitation is an auxiliary tool designed to assist the machine operator! For functional reasons, the working attachment cannot be brought to a sudden stop. The faster it is moved, the longer its braking distance. Risk of accident!

Please note that the machine operator is responsible for the correct adjustment of the relevant settings!

Avoid fast movements of the working attachment when it is operated near the maximum permissible working height.

Setting stroke limitation:

For a description, see chapter "Operator's menu", submenu "hbg max point".

Application of stroke limitation:

Stroke limitation on

The stroke limitation function is activated. The working tool can only be lifted to the maximum permissible working height.

Stroke limitation, preliminary shut-down

The preliminary shut-down function slows down the upward movement of the working attachment before the maximum permissible working height is reached (indicator light H159 on).

Stroke limitation, shut-down

The shut-down point of the maximum permissible working height is reached.

Stroke limitation overridden

The stroke limitation function is overridden so that the working attachment can be moved without restrictions.

Overriding stroke limitation:

Danger!

Risk of injury and damage to equipment!

If the stroke limitation function is overridden, there is a risk of serious damage and injury, as the equipment might collide with another object.

When overriding the limitation function, operate the machine with extreme caution.

Press the switch S291

The stroke limitation function is temporarily overridden. After the switch has been pressed, the equipment can be moved for 10 seconds to a height above the shut-down point.

The stroke limitation is automatically reactivated and the switch must be pressed again, –if the attachment is moved back to the permissible operating range –after a 10-second period has lapsed

3.4.17Stick cylinder shut-off function (optional equipment)

3.4.17.1Operating principle

When the boom is moved, it can reach great heights and outreaches. The stick with attached load might collide with the operator's cab or impact on other objects. There is even a risk of collision with the operator's cab or the object, which would likely result in injury to the operator, and damage to equipment or the attached load.

In order to assist the machine operator, the range of movement of the stick is limited by the electronic stick cylinder shut-off function.

This means that the stick can only be moved within a preset angle range (defined by a minimum and a maximum angle). The reach of the attachment thus depends on the stick cylinder shut-off point and the angle of the boom.

3.4.17.2Use of stick cylinder shut-off function

If the stick is to be moved beyond the shut-off limit, the stick shut-off function can be overridden.

If the machine is to be operated with movement limitation, the stick cylinder shut-off must be set to the maximum values.

The stick cylinder shut-off function –is always activated during operation –cannot be switched off –can only be overridden for short periods of time

Danger!

The electronic stick cylinder shut-off function is not a safety device in the narrow sense of the word and serves only as a utility for the machine operator!

Please note that the machine operator is responsible for the adjustment of the relevant settings!

Danger!

Despite the stick cylinder shut-off function, there remains a risk of damage to the operator's cab and objects in the vicinity of the machine. The machine might vibrate or swing! Risk of accident!

Possible causes:

–Oscillation of the working tool such as a grapple swinging from its stick, or where the size of a working tool is considerably increased when it is opened.

–Delayed shut-off. The shut-off travel might be extended by up to 0.5 m, depending on the oil temperature and the type of attached working tool. Under certain conditions, it might even be extended by up to 1.0 m (depending on the retracting speed and the grapple content).

–Jerking shut-off.

Adjust the stick cylinder shut-off so that there is a sufficient safety distance, even if the working tool is oscillating or if the shut-off is delayed. Avoid fast movements of the stick when it is moved near the shut-off limits.

The following operating statuses are indicated on the display:

3.4.17.3Overriding stick cylinder shut-off function

Danger!

Risk of injury and damage to equipment!

While the stick cylinder shut-off function is overridden, there is a risk that the attachment might collide with the operator's cab.

When overriding the stick cylinder shut-off function, operate the machine with extreme caution.

After the stick shut-off function has stopped the movement of the stick:

The stick cylinder shut-off function can be overridden by pressing the switch S216.
