1.1 Tilting the upper carriage – Vertical Digging System 28z3 (option)
Vertical digging on slopes is possible by tilting the upper carriage hydraulically by 15° with
the VDS.
Tilting the upper carriage:
☞ Hold button 1
☞ Press control lever 2 to the right
➥ The upper carriage is tilted
Lowering the upper carriage:
☞ Hold button 1
☞ Push control lever 2 to the left
➥ The upper carriage is lowered.
Bear in mind the following when working with the machine:
Tilting the machine in the immediate vicinity of walls or parts of buildings
carries a danger of crushing.
Danger of severe crushing of body!
☞ All persons must stay clear of the hazard zone when tilting the machine.
☞ Tilt the machine only on firm ground.
☞ Tilt the machine only if it is at a standstill and if the attachment is empty.
☞ All doors and covers must be closed when tilting the machine.
☞ Never turn, lower or set down the attachment abruptly.
☞ Do not extend or retract the boom abruptly. Otherwise there is danger of
tipping over!
☞ When working in the immediate vicinity of a wall or parts of a building, make
sure the upper carriage does not touch anything when it is tilted.
☞ On a slope, position the machine so that the upper carriage is tilted towards
the slope. Otherwise there is danger of tipping over!

center.
Edition 1.0 Supplementary Operator’s Manual for Protective Structures for Excavators 1-5
Supplementary Operator’s Manual for Protective Structures for Excavators
Definition of FOPS/Front Guard categories
Category I:
FOPS and Front Guard to protect against small falling objects or small objects penetrating
the cab from the front of the machine, such as bricks, small pieces of concrete, tools, for
machines that are used for repairing roads, landscaping work and for working on other
construction sites, for instance.
Category II:
FOPS or Front Guard to protect against heavy falling objects or heavy objects penetrating
the cab from the front of the machine, such as trees, pieces of rock, for machines that are
used for clearance work, demolition work and forestry work.
Responsibility for machine equipped with protective structures
The decision regarding the necessary protective structures (type and category I or II) must
be made by the machine operator and depends on the specific work situation.
The operator must observe the national regulations and he must inform the user on the
protective structure to be used in a specific work situation.

• A shatter protection must be installed on a canopy version if an attachment (a
hammer, for instance) causes fragments to fly. This shatter protection takes
over the function of a front window.
• Pay attention to the restricted work range (see fig. 13 and 14).
• For 803 machines up to serial number AI00966, operation with an attachment
causing fragments to fly is absolutely prohibited.
Accident hazard in conditions of restricted visibility due to
rain, snowfall, dust etc..
Could causes severe injury or death.
