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.

CAUTION
Never stop the engines from a full load except in case of emergency.
If a hot engine is shut down without previous idling period of three to five
minutes, the temperature in certain engine parts rising sharply after the cool-
ing system ceases to function. The resulting thermal stress, especially in the
turbochargers, may cause serious damage.

WARNING
The chambers of the counterweight are filled with a mixture of concrete, gran-
ulated ore and steel pellets. This mixture can create explosive gases which
will accumulate in the chambers of the counterweight. Before any welding,
flame-cutting, grinding or drilling procedures are carried out on the counter-
weight it is vital to expel these gases from the counterweight chambers. Fail-
ure to properly expel the gases from the counterweight chambers can result
in an explosion with serious personal injury or death.
Follow the instructions given in PARTS & SERVICE NEWS No. AH04518 for
expelling the gases from the counterweight chambers.

H31
speed by one or more of the six high pressure filters.
NOTICE
The LED ”H31” monitors all six high pressure filters. Refer to
page 219 for description of the diagnostic codes flashed out by LED
”H31”.
