Control, operation

of the machine during travel as well as working.

–The machine operator determines the vibration impact to a great part, since he himself selects the speed, the gear ratio, the working manner and the travel route. This results in a wide range of various vibration impacts for the same machine type.

The full body vibration impact for the machine operator can be reduced if the following recommendations are observed:

–Select the appropriate machine, equipment parts and auxiliary devices for the corresponding tasks.

–Keep the seat in good order and adjust it as follows:

•The seat adjustment and the suspension should be made according to the weight and the size of the operator.

•Check the suspension and the adjustment mechanism regularly and make sure that the characteristics of the seat remain as specified by the seat manufacturer.

–Check the maintenance condition of the machine, especially regarding: Tire pressure, brakes, steering, mechanical connections, etc.

–Do not steer, brake, accelerate and shift or move and load the attachment of the machine in a jerky manner.

–Match the machine speed to the travel route to avoid vibration impacts.

•Decrease the speed when driving on pathless terrain;

•Drive around obstacles and avoid very impassable terrain.

–Keep the quality of the terrain where the machine is working and travelling in good order:

•Remove large rocks and obstacles;

•Fill furrows and holes;

•To establish and retain suitable terrain conditions, keep machines available and allow for sufficient time.

–Travel longer distances (i.e. on public roads) with suitable (medium) speed.

–For machines, which are frequently used for travel, consider use of auxiliary ride control systems, and also monitor speed to minimize buildup of "pitching" vehicle movement.

3.4.2Low idle automatic

The idle automatic function automatically reduces the engine speed without actuation of the joystick or the travel pedal. This helps save fuel and reduces the noise level. By touching the joystick or the pedals, the engine speed returns to the initial level.

This function is activated with the low idle automatic button:

Press the button.

The idle automatic is activated. The indicator light in the switch flashes.

Press the button again.

The idle automatic is deactivated. The indicator light in the switch is off.

3.4.3Working position

Setting the machine into working position:

Caution!

If the parking brake is applied during work, the drive might become damaged. A buzzer sound indicates that the parking brake is applied during operation. For braking during work, use the brake pedal (operating brake).

Set the travel direction switch S263 to its neutral position 0.

Press the brake pedal 1 to the stop and ensure that the retainer (see arrow) is engaged.

Release the parking brake S16.

Lock the oscillating axle (switch S75 to position 1).

As a general rule, work with the machine must be performed across the rigid axle.

3.4.4Operating the working attachment

Caution!

The machine is equipped with PCSA controls as standard. On 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 left joystick (1) controls the stick and swivelling movements:

–Movement in direction a and b: Stick is extended or retracted.

–Movement in direction c and d: Uppercarriage is swivelled to the left or right.

The right joystick (2) controls the boom, digging bucket and grapple movements:

–Movement in direction e and f: Digging bucket is tilted inwards or outwards. Grapple is closed or opened.

–Movement in direction g and h: Boom is lifted or lowered.

Moving the stick:

The stick is moved by operating the left joystick 1

Push the joystick back a: Stick moves in direction a

Push the joystick forward b Stick moves in direction b

Moving the boom:

The boom is moved by operating the right joystick 2.

Push the joystick back g: Boom is lifted.

Push the joystick forward h: Boom is lowered.

Moving the digging bucket:

The digging bucket is moved by operating the right joystick 2

Move the joystick to the left e: Digging bucket is tilted inwards.

Move the joystick to the right f: Digging bucket is tilted outwards.

Operating the grapple:

Danger

Risk of injury to persons standing in the danger area. Do not allow auxiliary personnel hand-guide the grapple!

The digging bucket is moved by operating the right joystick 2 Move the joystick to the left e: Grapple is closed.

Move the joystick to the right f: Grapple is opened.

Combined movements:

Diagonal movement of a joystick results in a combination of the associated working movements. Operators can thus complete different attachment movements simultaneously.

3.4.5Moving the boom

Ensure that the tool attachment is deactivated (switch S241 off). Press the foot pedal k down. The attachment is lifted.

Press the foot pedal m down. The attachment is lowered.

3.4.6Horizontal boom movement (optional equipment)

3.4.6.1Gooseneck boom allowing for horizontal movement

Ensure that the working tool is deactivated (switch S241 off). Press the foot pedal k down. The boom is swivelled to the right. Press the foot pedal m down. The boom is swivelled to the left.

3.4.6.2Vertically and horizontally adjustable boom

Option 1: without hydraulic working tool

This option is available in machines equipped with a vertically and horizontally adjustable boom and if no working tool is to be operated.

The machine is equipped with the accessory kit AHS 12.

The machine features a vertically and horizontally adjustable boom and the switch S241. The switch is exclusively designed for the adjustment of the boom.

Vertical movement of the boom:

Press the switch S41 up. The indicator light in the switch is not on. Press the foot pedal k down. The attachment is lifted.

Press the foot pedal m down. The attachment is lowered.

Horizontal movement of the boom

Press the switch S241 down. The indicator light in the switch is on. Press the foot pedal k down. The boom is swivelled to the right. Press the foot pedal m down. The boom is swivelled to the left.

Option 2: with hydraulic working tool

Fig. 3-76 Vertically and horizontally adjustable boom, switchover

This option is available in machines that allow for the simultaneous operation of a vertically and horizontally adjustable boom and a working tool. Ensure that the working tool is deactivated (switch S241 off).

Vertical movement of the boom:

Press the foot pedal k down. The attachment is lifted.

Press the foot pedal m down. The attachment is lowered.
