When the implement is in transport position, always ensure that the tractor three-point linkage is
sufficiently locked to the sides!
When driving on roads with the implement lifted, the operating lever must be locked against lowering!
When mounting the implement, the operator must ensure that there is a metallic connection (ensured
by the lower link) made to the tractor.
The operator must ensure that no one is standing close to the implement when it or its components
are being moved by the tractor hydraulic system or when the side wings are being lifted or lowered.
Visual check by the driver!
When driving on roads, which is only permitted with the implement lifted and with folded side wings,
the control block on the hydraulic cylinder prevents lowering of the implement as well as of the folded
up side wings (additionally secured with a chain). The secured chain also prevents accidental lowering
of the side frame during road transport in case of failure of the tractor hydraulic system.
Mounting of any sort of accessories onto the implement must be performed according to standards.
The maximum permitted total weight may not be exceeded.
Only APV implements and accessories may be mounted on the implement.
Accessories must be mounted in compliance with the standards by qualified specialist personnel from
an authorised company.

HYDRAULIC SYSTEM
Inspect the hydraulic hose lines at regular intervals and replace in case of damage or wear! The
replacement lines must comply with the technical requirements of the implement manufacturer!
The hydraulic system is under high pressure!
When connecting hydraulic cylinders and motors, the specified connection of the hydraulic hoses must
be observed!
When connecting the hydraulic hoses to the tractor hydraulic system, make sure that the hydraulic
system on the tractor and implement side is
unpressurised
!
For hydraulic function connections between the tractor and implement, coupling sleeves and coupling
connectors should be marked to exclude the possibility of operating errors! If the connections are
interchanged, the function will be inverted (e.g. lifting/lowering)!
– Danger of accident!
Due to the risk of injury, use suitable tools when searching for leaks!
Liquids escaping under high pressure (hydraulic oil) can penetrate skin and cause serious injuries!
Consult a doctor immediately in case of injury! (Risk of infection!)
Before working on the hydraulic system, park the implement, depressurize the system and switch off
the motor!
The securing chain should only be unhooked when it is relieved of tension (cylinder must be filled with
oil)!
5.5
MAINTENANCE
Maintenance, repair, and cleaning work as well as the elimination of malfunctions should always be
performed when the drive is switched off and the motor is at a standstill and the implement is uncoupled
from the towing vehicle! Remove the ignition key!
The maintenance work itself may only be performed by trained specialist personnel and may never be
performed alone. Extreme caution must be taken when changing defective components or tools.
If repair or maintenance work is required on the implement, this work must be identified by a clearly
visible information sign "Caution: maintenance work".
Check the nuts and bolts regularly for tight fit and retighten if necessary!
When performing maintenance on the lifted implement, always ensure safety against lowering through
suitable support elements!
When changing working tools with sharp edges, always use suitable tools and cut-resistant gloves!
Replacing components that cannot be removed with tools such as a screwdriver or wrench may only
be replaced by qualified specialist personnel from an appropriately authorised company or by APV
Customer Service.
Dispose of oils, greases and filters according to the national regulations!
Always cut the power supply when working on the electrical system!
