•Risk of crushing and shearing when operating the support devices!
•Be particularly careful when coupling to and uncoupling from the machine! There are crushing
and shearing points in the vicinity of the coupling points between the machine and the
attachment!
•Persons must not be standing between the machine and attachment when the three-point
hydraulics are operated!
•Monitor the coupled supply lines. Coupled supply lines:
οmust give way slightly when driving around corners without tension, kinking or friction,
οmust not chafe against external components!
•Always place the uncoupled attachment in such a way that it is stable!
Use of the attachment
•Before starting work, familiarise yourself with all of the equipment and operating elements of the
attachment, including the functionality thereof. There is no time for this once work has started!
•Wear closely fitting clothes! Loose fitting clothing increases the risk of grabbing or entanglement
in the drive shafts!

οin the rotating and swivelling area of the moving parts of the attachment,

Safety notes
Page
2-7
οbeneath the raised and unsecured moving parts of the attachment!
•There are crushing and shearing points at the externally-operated (e.g. hydraulically) moving
parts of the attachment!
•The externally-operated parts of the attachment may only be operated if there are no persons in
the hazard area of the attachment!
•Safeguard the machine from unintentional start-up or rolling away before leaving the machine!
•Support the raised covers before standing beneath them!
Transporting the attachment
•Before transport, check:
οthat the power supply lines are connected properly,
οthe hydraulic system for obvious defects,
•Always ensure that the machine has sufficient steering and braking capability!
•The attachment attached to the machine and the rear weights which are present influence the
driving behaviour of the machine as well as the steering and braking capability.
•Use rear weights if necessary!
•Always fasten the rear weights to the provided fixing points properly!
•Observe the maximum load capacity of the attached attachment and the permitted axle and
support loads of the machine!
•Check the brakes before setting off! The machine must possess the prescribed braking
deceleration for the combination of the machine plus the attachment!
•Take the projection and oscillating weight of the attached attachment into consideration when
cornering!
•Avoid sudden turns particularly during uphill and downhill driving and when driving parallel to a
slope!
•Bring all moving parts of the attachment into the transport position before transport trips!
•Secure all moving parts of the attachment in the transport position before undertaking transport
trips. Use the transport locks provided!
•Adapt your driving speed to the prevailing conditions!
2.4.2 Hydraulic system
The hydraulic system is under high pressure.
•Make sure the hydraulic lines are connected correctly!
•Ensure that the hydraulic system of the machine and the attachment is depressurised when
connecting the hydraulic lines!
•Do not block any operating levers on the machine which are used for directly carrying out
hydraulic or electrical movements of components, e.g. folding, swivelling and pushing operations!
•The respective movement must stop automatically if the relevant operating lever is released.
•This does not apply to equipment movements that:
οare continuous,
οare automatically controlled,
οrequire a floating or pressure position for functional reasons.

Safety notes
Page
2-8
•Before working on the hydraulic system:
οlower the attachment,
οsafeguard parts of the attachment which are raised from unintentional lowering,
οdepressurise the hydraulic system,
οturn off the engine of the machine,
οapply the parking brake,
οremove the ignition key!
•Have the hydraulic lines checked by an expert at least once a year in order to ensure that they
are in a safe working condition!
•Replace hydraulic lines if they are obviously defective, damaged or old! Always use original
hydraulic lines!
•The six year usage duration of the hydraulic lines must not be exceeded, including a maximum
possible storage time of two years!
Even though they are stored properly and only subjected to the permissible loads, hoses and
hose connections are subject to natural ageing, therefore their storage time and usage duration is
limited. The usage duration can differ from this in accordance with empirical values, particularly
taking the hazard risk into consideration. The same guideline values apply for hoses and
hydraulic lines made from thermoplastics.
•Never try to seal up leaking hydraulic lines using your hands or fingers!
Liquids (hydraulic oil) escaping under high pressure may penetrate the skin and cause severe
injuries!
In the event of injuries caused by hydraulic oil, seek immediate medical attention! Danger of
infection!
•Do not use your bare hands to detect leaks because of possible severe risk of infection! Use a
suitable aid when looking for leaks (cleaning spray, special leak-finding spray)!
2.4.3 Attachment
•Only one person may operate the attachment! Remove bystanders from the hazard area of the
attachment!
•The following is strictly prohibited:
οclimbing onto the upper edge of the receptacle,
οclimbing or reaching into the receptacle with the engine of the machine running!
•No person may be present in the work area of the attachment!
Danger due to objects being flung out of the discharge opening.
•Remove all persons from the work area of the attachment before operating it!
•Do not place any foreign objects into the receptacle!
