workingon hillyground(particularlyforstandard hitchmodels).
HYDRAULIC SYSTEM
1. WARNING! Hydraulic system is under pressure (maximum working pressure : 200 bars /
2900psi). Any liquidunderpressure (particularlyoil from hydraulics)canpenetrate the skin
andcause severeinjury. If injured,seeadoctorimmediately,therecould bedangerof infec-
tion.
2. Whenfitting hydraulicmotorsorcylinders,ensure thatall connectionsaremadecorrectly, as

SPECIALSAFETYRECOMMENDATIONS
1. Use only a tractor equipped with an enclosed cab and ROPS with windows made
of safety glass and kept closed. Itisrecommendedtofitpolycarbonatescreensinside
the tractor safety cab’s side and rear windows or to install mesh guards on the exterior of
them.
2. Staya safe distanceaway from themowerwhendiscs are rotating.
3. For safe machine operation, it is imperative that cutting tools be fitted in accordance with
themanufacturer’srecommendations. Useonlythe toolsupplied withthemachine forthat
effect.
4. Each time before using the mower, inspect condition of cutting elements (blades, discs).
Replaceany missing,wornor damagedcuttingelementsimmediately. Use only genuine
KUHN service parts.
5. To avoid creating dangerous out of balance forces, always replace missing, damaged or
wornbladesinpairs.
6. Whenreplacing bladesordiscs,systematically inspect theirsecuringelements as perthe
manufacturer’srecommendations.
7. Regularlyinspectthediscmower’sprotectioncover. Wornor damagedprotectioncov-ers
mustbereplaced immediately.
8. Protectiondevices (such asguards,shieldsetc.) are intended topreventstones,rocks or
other foreign objects from being projected. They also prevent access to the machine’s
danger zones. Therefore, it is imperative that all protection devices be in place and prop-
erlysecuredeach timebeforeusingthe machine.
9. Crushingand shearingzones,whichcould causeseriousbodilyinjury when changingthe
machine from transport to work position and vice versa may exist. To prevent possible
injury, be extra careful when maneuvering and ensure that everyone is at a safe distance
awayfrom themachine.
10. Beforetransporting themachineon publicroads, lockthetongue withthemachine’strans-
portpinand theliftcylinders inpositionbyclosing theliftcylinder securityvalves.
11. PTO drive to the mower must never be engaged unless the cutterbar skid shoes are in
contactwiththe groundandall protective coversarefolded down.
12. Makesurethattheground to be mown is free of obstructionsorforeignobjectssubjectto
enteringthe cutterbar. Increasecuttingheight toclearany hiddendebris.
SAFETY RECOMMENDATIONS

- 11 -
13. Evenwhenthe machineisused inaccordancewith itspurpose,objects maybeprojected.
Itistherefore imperative that everyoneiskept away from thedangerzone,that extra care
betakenand thatextraprecaution (suchassafety indicators)betaken when mowingpas-
tures alongside roads or near public areas.
14. Nevermow inreverse.
15. When disengaging thePTOdrive, movingparts continue torotate for sometime. Waitfor
all moving parts to come to a complete stop before leaving the cab and approaching the
machine.
16. Ifanobstructionis hit, stop the tractorimmediately, disengagePTOdrive,turn off engine,
removeignitionkeyand wait for all moving partstocometoa complete stop.
Checktheentire machine foranydamage before resumingwork.
17. Itisstronglyrecommended to have yourmachinecheckedby your dealer aftereachsea-
son,especiallyblades and discsandtheirfixing devices (nuts,bolts,etc.).
