SAFETY 2.1 SAFETY INSTRUCTIONS
● Always keep at a distance from the edges of building pits and
slopes.
● Avoid any operation that might be a risk to machine stability.
● Never travel across slopes; always keep the working equip-
ment and the load close to the ground, especially when trav-
elling downhill.
● On sloping terrain always adapt your travelling speed to the
prevailing ground conditions. Never change to a lower gear
on a slope but always before reaching it.
● Before leaving the driver’s seat always secure the machine
against inadvertent movement and unauthorized use.
SPECIAL WORK IN CONJUNCTION WITH UTILIZA-
TION OF THE MACHINE AND MAINTENANCE AND
REPAIRS DURING OPERATION; DISPOSAL OF
PARTS AND CONSUMABLES
● Observe the adjusting, maintenance and inspection activities
and intervals set out in the Operation,- Lubrication and Main-
tenance Manual, including information on the replacement of
parts and equipment. These activities may be executed by
skilled personnel only.
● Brief operating personnel before beginning special operations
and maintenance work, and appoint a person to supervise the
activities.
● In any work concerning the operation, conversion or adjust-
ment of the machine and its safety-oriented devices or any
work related to maintenance, inspection and repair, always
observe the start-up and shut-down procedures set out in the
Operation,- Lubrication and Maintenance Manual and the
information on maintenance work.
● Ensure that the maintenance area is adequately secured.
● If the machine is completely shut down for maintenance and
repair work, it must be secured against inadvertent starting
by:
❍ locking the principal control elements and removing the
ignition key and/or
❍ attaching a warning sign to the main switch
● Carry out maintenance and repair work only if the machine is
positioned on stable and level ground and has been secured
against inadvertent movement and buckling.
● To avoid the risk of accidents, individual parts and large
assemblies being moved for replacement purposes should be
carefully attached to lifting tackle and secured. Use only suit-
able and technically perfect lifting gear and suspension sys-
tems with adequate lifting capacity. Never work or stand
under suspended loads.

SAFETY 2.1 SAFETY INSTRUCTIONS
INSTRUCTIONS FOR USE
Open the lock, lift the harness by the catch hook (C), the blue
straps (leg straps J) are below. The harness is being put on just
like a jacket. Pull the belly strap (E) through the lock, as shown on
the illustration, and secure it.
By closing the breast strap, you avoid the shoulder straps to side-
slip. Bring the leg straps (J) around the legs to the front, pull them
in, as shown in the illustration, and tighten them. Adapt the har-
ness to body form, seeing to perfect fit, in particular that the
catching hook (C) be in the center of the back.
The safety harness should belong to its wearer personally.
The safety harness should only be used together with connectors
acc. to EN 354, and fall arrest acc. to EN 355, or fall protection
devices acc. to EN 360.
The attachment point for the safety harness should be above the
wearer, and the carrying capacity of the attachment point should
be sufficient to correspond with the minimum carrying capacity
acc. to EN 795.

OPERATION 3.4 ELECTRONIC MONITORING AND CONTROL SYSTEM ECS
Automatic Display of Messages
If a fault or an information condition occurs during operation, the
basic display is automatically replaced by a message in text. If a
further condition occurs, another message is displayed so that the
operator is always shown the latest message.
The message text provides the operator with an explanation of
the condition in standard texts.
When a fault message is displayed, further ”HELP” information
relating to the fault message can be obtained by pressing the
”DOWN” key (3), illust. Z21730. All fault and information mes-
sages are listed in section ”Message Texts”. Each message is
related to a page. These MESSAGE PAGES are numbered and
can be called up individually. When a fault message is displayed
the number of operating hours is displayed and stored at the
same time. Fault and information messages are held as long as
their cause is existent
Maintenance Schedule
In accordance with the operating hours of the Excavator, the initial
and periodic maintenance intervals are automatically displayed.
Example:
After the first 250 operating hours of the Excavator the following
message will be displayed:
# Initial 250 h Maintenance
Perform initial 250 h Maintenance.
Perform maintenance according to the Maintenance section.
Acknowledgement of performed maintenance.
The acknowledgement of performed maintenance is obtained in
the main group ”Service” under menu item ”Maintenance” refer to
Menu Control Chart -V- on page 127.

Return to SYSTEM level:
Display of the Last Message Received or Menu
(Standard Display)
Operation of the keyboard (B) has no influence to the recording of
input messages. For example, if the record memory is called up
via keyboard (B), the ECS switches back to SYSTEM level after a
period of 20 seconds when no further key is actuated within this
period. For immediate return to SYSTEM level (message display
or menu) press key 5 (SYSTEM).
Setting of Screen Brightness
Increase brightness: Press keys (5 and 2) simultaneously.
Decrease brightness: Press keys (5 and 3) simultaneously.
Ex works the display is adjusted to maximum brightness (basic
setting). Any change of the screen brightness via keyboard (B)
will be kept until the system is switched off. When the system is
switched on again, the maximum brightness of screen (A) will be
restored automatically (basic setting).
System Languages
The text of the messages and of the menu control of the ECS-
System is available in 2 languages and can be selected in the
main group SERVICE with the menu control.
Refer to the section ”SERVICE FUNCTIONS AND MENU CON-
TROL” for further information.
Message Numbers and Message PAGE Numbers
Each message of the two available system languages is related
to a message page. The message number and the message
PAGE number are identical for the first language, e.g. English.
The message PAGE numbers of the second language have
always a higher number (offset), although the message number
itself remains the same.
If, for example, the message number. 500
($h: Start blocked because of main Shut-Off (gate) valve)
is displayed in the English (first) language, the applying message
PAGE number is also 500. In the second language e.g. German
the message page number is 503. The message number dis-
played on the screen never changes, only the related message
page number in the second language changes. If the contents of
the protocol memory are printed out in the second language, only
the message page numbers of the second language are shown
on the print. Depending on the type of the message, the mes-
sage PAGE number of the second language will be higher than
the message number by the following numbers (offsets):
Message number range 500-1309: message pages with 3 num-
bers offset
Message number range 1310-1349: message pages with 1 num-
ber offset
Message number range 1350-1439: message pages with 2 num-
bers offset
Message number range 1440-1515: message pages with 5 num-
bers offset
