Control and operation

as follows by the rocker switch S57:

Tilt down the rocker switch S57 on the joystick handle, the brake is applied when the uppercar riage is at standstill, respectively it applies as soon as the uppercarriage speed gets lower than a limit value.

Tilt up the rocker switch S57, the brake remains released permanently.

Note!

The red LED beside the touch S17 is lighting in any case when the brake is applied. If this light does not go out when the rocker switch S57 is tilted up, the button S17 must first be pushed to pre-select the semi-automatic mode.

Caution!

The brake only applies when the uppercarriage is near standstill and if no swing motion is actuated via the joystick! In order to stop the uppercarriage when working on a slope, tilt the switch S57 down and reduce the uppercarriage speed by braking with joystick 4. Move the joystick 4 back to «0» position only after the brake has applied.

Ermergency stop of the uppercarriage swing motion

The swing brake can be applied independently of the uppercarriage RPM by switching the button S17 from position «semi-automatic» into position «applied».

Caution

Perform this braking via button S17 only exceptionaly, i. e. in emergency cases, since it causes fast abrasion of the brake discs.

To check the mechanical swing gear brake: When the uppercarriage is stationary. Press the touch S17 to apply the mechanical swing brake. Push the left joystick 4 to the right and then to the left as far as the stop. If the swing brake function is OK, the uppercarriage does not start swinging.

The positioning swing brake (option)

The positioning swing brake is used for progressive and sensitive braking of the upper carriage.

Note!

Increased wear.

Do not use the positioning swing brake purely as a service brake, but only as a stop and parking brake.

Using this brake to stop the uppercarriage running at the full swing RPM is not permissible since this would result in a quick abrasion of the brake discs.

In any case, first use the hydraulic braking to greatly reduce the speed of the uppercarriage

Depress the pedal 10 when the uppercarriage is near standstill

The uppercarriage can be stopped precisely and progressively in the desired position.

3.4.5 Working position

Work on a level, flat and firm ground. If necessary arrange the working place and free it of obstacles.

As a general rule, work with the attachment over the idler wheels.

Note!

Position the undercarriage so that it is situated lenghtwise to the working attachment and with the sprocket wheels at the rear, when the load is at its maximum reach during the working cycle.

3.4.6Working attachment control

Caution!

The joystick functions described below refer to the normal control, fitting out the machine at delivery.and according to ISO-standards, On machines equiped in addition with a special control system, and if this special control system is activated by the operator, the joystick functions correspond to the information on the label which is sticked on the side window of the cab and is specific to the installed special control system.

Control of the stick cylinder

3-71 Stick cylinder control

The stick cylinder is operated using the left joystick 4 Pull the joystick 4 back (a) The stick is moved in. Push the joystick 4 forwards (b) The stick is moved out.

Control of the boom cylinders

The boom cylinders are operated using the right joystick 3

Fig. 3-72 Boom cylinders control

Pull the joystick 3 back (g) The working attachment is raised. Push the joystick 3 forwards (h). The working attachment is lowered.

Control of the grapple cylinders

The grapple cylinders are controlled by the right joystick 3.

Fig. 3-73 Operation of the grapple cylinders

Push the joystick 3 to the left e The the grapple closes. Push the joystick 3 to the right f The grapple opens.

Danger

Never allow anybody to guide the grapple by hand!

Combined movements

A diagonal movement of the joystick combines the corresponding movements of the working attachment. This makes it possible for all attachment movements to be ac- tuated at the same time.

3.4.7Lowering the working attachment with the engine shut down

In an emergency, the attachment can be lowered also when the engine is not running.

Note

The attachment can be lowered thanks to a pressure accumulator mounted to the control oil unit. Due to the small volume of this accumulator only a limited number of movements can be actuated by the pilot control devices.

Only operate the joysticks in the directions for lowering the attachment. Only the movements resulting from the own weight of the attachment parts are possible.

Turn the ignition key to contact position 1

Actuate the desired movement(s) while deflecting the joysticks (eventually also the foot pedals in case of special attachment) until the equipment has lowered to the required position.

3.4.8Rotating, tilting, locking and unlocking a working tool

An additional hydraulic circuit must be activated to operate some specific working tools such as:

•a rotating grapple (A),

•a rotating bucket (B),

•a hydraulic quick-change adapter (C).

The medium pressure circuit is activated via the touch S19 on the main control unit.

The working tool is then actuated via the both push buttons S5L and S5R mounted at the top of the handle of the left joystick 4

Press the touch S19

The medium pressure circuit is activated. The LED of the touch is lighting.

Press the left push button S5L and keep it pressed.

The working tool is actuated to the left (the grapple is rotated to the left, or the bucket is swivelled to the left, or the locking pins of the hydraulic quick-change adapter are driving out, ...).

Fig. 3-75 Actuation of working tools

Press the right push button S5R and keep it pressed. The working tool is actuated to the right (the grapple is rotated to the right, or the bucket is swivelled to the right, or the locking pins of the hydraulic quickchange adapter are retracted, ...).

The movement of the working tool is stopped as soon as the push button S5L or S5R is released.

Press the touch S19 again.

The medium pressure circuit is deactivated and the working tool can not be actuated any more. The LED of the touch goes out.

Note!

With the option "Left joystick with proportional control" installed, the working tool can be actuated in a proportional way, while deflecting the mini joystick A185 on the left joystick to the left "X-" (resp. to the right "X+").

Caution!

On machines destined to the North American market, and which are fitted with a lifting magnet, the rotating device is controlled by the push buttons S6L and S6R in the handle of the right joystick 3. Also see the section "joysticks" in this chapter.

3.4.9Control of additional attachments via the additional pedals

If necessary, select the mounted additional attachment in the menu "Set Option". This selection determines pressure and oil flow adjustment in the hydraulic circuit,
