• Wear protective clothing and equipment when
fastening, guiding and removing loads (for example a
hard hat, safety glasses, protective gloves, safety
boots).
• Do not place lifting and fastening gear over sharp
edges or rotating parts. Loads must be fastened so as
to prevent them from slipping or falling.
• Move loads only on horizontal, level and firm ground.
• Move loads close to the ground.

Safety 2
Lifting gear applications

• The machine and the attachment must be certified for
lifting gear applications.
• Observe the national regulations for lifting gear appli-
cations.
• Lifting gear applications are procedures involving
raising, transporting and lowering loads with the help
of lifting and fastening gear.
• The help of an accompanying person is necessary for
fastening, guiding and removing the load.
• There must be nobody under the load.
• Stop the vehicle immediately and stop the engine if
persons enter the danger zone.
• Use the machine for lifting gear applications ONLY if
the mandatory lifting gear (for example, a joint rod and
load hook) and safety equipment (for example, optical
and acoustic warning devices, hose burst valve,
stability table) is installed and functional.
• Use only lifting and fastening gear certified by a test/
certification body, observe the inspection intervals
(Use only chains and shackles. No belts, slings or
cables).
• Do not use any lifting and fastening gear that is dirty,
damaged or not of sufficient size.
• Do not interrupt the work process with a load attached.

• The specific national driving license is required.
• Carrying passengers on/in trailers is PROHIBITED.
• Observe the maximum permissible vertical and trailer
load.
• Do not exceed the permissible trailer speed.
• Trailer operation with the towing gear of the machine is
prohibited.
• Trailer operation changes the machine’s operating
behavior, the operator must be familiar with this and
act accordingly.
• Bear in mind the machine’s steering mode and the
trailer’s turning circle.
• Before hitching/unhitching the trailer, secure it to
prevent it from rolling away (for example, with the
parking brake, suitable wheel chocks).
• There must be nobody between the vehicle and the
trailer when hitching a trailer.
• Hitch the trailer onto the vehicle correctly.
• Ensure that all equipment works correctly (for
example, the brakes, lights).

Removing and fitting attachments

• Before uncoupling or coupling hydraulic connections:
- Stop the engine
- Release the pressure in the operating hydraulics
• Picking up and lowering attachments to the ground
requires special care:
- Pick up and safely lock the attachment in accor-
dance with the Operator’s Manual.
- Lower the attachment only to firm, level ground and
secure it to prevent it from tipping over or rolling
away.
• Put the vehicle and the attachment into operation only

2.8 Towing, loading and transporting

Towing
• Seal off the danger zone.
• Ensure that no one is near the towing bar or cable. The
safety distance is equal to 1.5 times the length of the
towing equipment.
• Observe the mandatory transport position, permissible
speed and itinerary.
• A tractor vehicle of the same weight category must be
used as a minimum. Furthermore, the tractor vehicle
must be equipped with a safe braking system and
sufficient tractive power.
• Use only towing bars or cables certified by a test/certi-
fication body, observe the inspection intervals.
• Do not use any towing bars or cables that are dirty,
• Fasten towing bars or cables only at the defined
points.
• Tow away only in accordance with this Operator’s
Manual to avoid damage to the vehicle.
• Observe the national regulations (for example, the light
regulations) when towing on public roads/sites.

Safety 2
Transportation
• For the safe transportation of the machine:
- The transport vehicle must have a sufficient load
capacity and platform – see “Technical data”
- The maximum weight rating of the transport vehicle
must not be exceeded.
• Use only lifting and fastening gear certified by a test/
certification body, observe the inspection intervals.
• Do not use any lifting and fastening gear that is dirty,
• In order to secure the machine on the platform, use
only the fastening points provided for this purpose.
• Ensure that nobody is in or on the vehicle during trans-
portation.
• Observe the national regulations (for example,
“Merkheft Erdbaumaschinen”, leaflet on earth moving
machines of the German employers’ liability insurance

The differential is locked with the differential lock. This
avoids uneven wheel spin. The differential lock
neutralizes the compensating effect of the differentials. In
other words, traction is evenly distributed to all wheels.
Information
If the vehicle is equipped with a differential lock, an 37
optional control lever is used (as shown in Fig. 48).

Description of the Vertical Lift System (VLS)

The “Vertical Lift System” (VLS) is an operator assistance
system that makes operating the machine easier with a
semi-automatic telescoping movement when raising or
lowering loads. The almost vertical raising and lowering
movement of the boom improves machine stability.
When it is raised, the boom only automatically extends in
the upper range if forklift mode is switched on (Fig. 70).
When it is lowered, the boom automatically retracts in the
upper range if forklift or bucket mode is switched on. This Upper range
ensures that the machine cannot suddenly reach the
overload range and tip over to the front.
Information
The boom does not extend automatically in the case of
loads over 700 kg.
Lower range
Fig. 70

Operation 5
Functional check of the Vertical Lift System (VLS)

Before starting work, fully raise and lower the unloaded
boom once with forklift mode switched on. The boom
must extend automatically in the upper range. When
lowered, the boom must retract automatically in the upper
range. If this is not the case, the Vertical Lift System is
malfunctioning. Do not work with the machine in this case.
The Vertical Lift System must be checked, adjusted and
repaired by qualified personnel.
35
Information
The Vertical Lift System (VLS) is a safety feature that
must always be checked for correct functioning before

starting work.
Pressing and holding the button 35 with the stacking

mode switched on (Fig. 69) can prevent the telescopic
boom from automatically extending when it is raised. For
safety reasons however, the boom cannot be lowered and
extended at the same time in the upper range.

WARNING
Injury hazard due to rotating parts!
Clothes and limbs can get caught on rotating parts.
► For PTO shaft operation, only use cardan shafts with
working protective devices. Check before use whether
the protective devices are installed and functional.
Replace damaged or missing protective devices.
► Check before use whether the cardan shaft and
protective devices are fastened correctly.
NOTICE
The maximum articulation angle of cardan shafts depends
on the design, shape and size of the protective devices.

Burn hazard due to hot hydraulic oil!
Hot hydraulic oil can cause burns to the skin.

The hydraulic oil radiator is located in a combined
radiator. The radiator is installed in the engine
compartment (Fig. 153).
One part cools the hydraulic oil, the other part the engine.
If the hydraulic system overheats during extended
machine travel on the road or under high outside
temperatures, check whether the fan drive works. Also
check whether the spaces between the radiator fins are
clean and not blocked.

Breather filter/hydraulic oil filler neck

The breather filter is located on the hydraulic oil tank
(Fig. 154). It ensures the ventilation of the hydraulic oil
reservoir when the hydraulic oil level varies. The breather
filter contains a filter element that prevents dust and dirt
from entering and squirts of oil from escaping. The
breather filter contains a valve that keeps the pressure in
the reservoir at around 0.2 bar. This pressure escapes
when the hydraulic oil filler neck is opened.
Information
Replace the breather filter after 1000 operating hours! Fig. 154

9.11 Noise emissions

9.12 Vibration
Overview
Hand/arm vibrations:
Noise values dB(A) Hand-arm vibrations do not exceed 2.5 m/s² (98.42 in/s²).
Average sound power level LwA 99.3 Full-body vibrations:

Guaranteed sound power level LwA 101 This machine is equipped with an operator's seat that
complies with EN ISO 7096:2000 requirements.
Specified sound pressure level LpA 84
When the machine is used in accordance with its
designated use, full-body vibrations vary from less than
0.5 m/s² (19.69 in/s²) up to a momentary maximum value.
When calculating the vibration values in accordance with
ISO/TR 25398:2006, you are advised to use the values
specified in the table. Here the actual conditions of use
must be taken into account.
Wheel loaders and teleloaders are classified according to
their operating weight.
