3.4.8Lowering the work equipment when the engine is not running

In an emergency, the equipment can be lowered when the diesel engine is not running.

Fig. 3-54 Lowering the equipment when engine is not running

Turn the ignition key to contact position 1.

Operate the joystick or the foot pedals until the equipment has lowered.

Note

The equipment can be lowered because of the control oil unit’s pressure reserve. This reserve is limited and is only sufficient for small movements of the pilot control devices.

Only operate the joystick in the directions for lowering the equipment.

3.4.9Turning, rotating, locking and unlocking the attachments

Switch S19 is used to activate an additional function:

–rotating grapple (A)

–rotating ditch cleaning bucket (B)

–locking pin for hydraulic quick change adapter (C)

To operate, press the push button. The push buttons are located on the left and /or right joystick (depending on the machine configuration):

E Operation with left joystick (standard)

F Operation with left and right joystick (option)

Danger!

Never allow anyone to guide the grapple by hand!

3.4.10Activating attachment unit (AHS, option)

The machine can move attachments (auxiliary users) with different pressure and flow settings.

Caution!

Incorrect preselection of the pressure and flow setting can result in damage to the work tool (e.g. hydraulic hammer) or in limited function.

Danger!

If a large or wide work tool (eg. grab) is made to vibrate in the vicinity of the cab, the cab could be knocked or buckled, which would expose the operator of the machine to danger.
