researchandimprovements.Youwillfind,ashavethousandsofownersallovertheworld,that
you have the best that engineering skill and actual field testing can produce. You have
purchased a dependable machine, but only by proper care and operation can you expect to
receive the performance and long service built into it.
This manual contains all the necessary information for you to receive full efficiency from your
machine.Theperformanceyougetfromthismachineislargelydependantuponhowwellyou
readandunderstandthismanualandapplythisknowledge.PleaseDONOTASSUMETHAT
YOU KNOW HOW TO OPERATE AND MAINTAIN YOUR MACHINE before reading this
manual carefully. KEEP THIS MANUAL AVAILABLE FOR REFERENCE.
YourKUHN dealerwillinstruct youonthegeneral operationofyourmachine. Heisinterested
that you get the best performance possible and will be glad to answer any special questions
that may arise regarding the operation of the KUHN machine.
Your KUHN dealer can offer a complete line of genuine KUHN service parts.
These parts are manufactured and carefully inspected in the same factory that builds the
machine to assure high quality and accurate fitting of any necessary replacements.
When ordering service parts it is important that you indicate the type of machine concerned
and its serial number.
Forthisreasonpleasecompletethemodelidentificationplatediagrambelowwiththerequired
information. This will provide you with an easy reference for future service parts orders.
ABOUT IMPROVEMENTS
KUHN iscontinuallystriving to improveitsproducts and,therefore,reserves the righttomake
improvements or changes when it becomes practical to do so, without incurring any
obligations to make changes or additions to the equipment sold previously.

or worn hoses must immediately be replaced .
Whenreplacingthehydraulichoses,makesuretousehoseswiththespecificationsandqualityrecommended
bythe manufacturer ofthemachine.
6. Should a leak be found, take all necessary precautions to avoid accidents.
7. Any liquid under pressure (particularly oil from hydraulics) can penetrate the skin and cause severe injury. If
injured,see a doctor immediately,therecould be dangerofinfection.

MAINTENANCE
1. Before checking for any machine malfunction and before adjusting, maintaining or repairing the machine,
disengage PTO, turn off engine and remove ignition key.
2. Check tightness of nuts and bolts regularly. Retighten if necessary.
3. If the machine is raised, prop it up in a stable position before carrying out any maintenance work.
4. Whenreplacing a working part,wearprotection gloves andonlyuse standardized tools.
5. It is forbidden to discard any oil, grease or filters. These must be given to waste disposal organisations to
protecttheenvironment.
6. Disconnect power source before any work is done to the electric system.
7. Check safety guards regularly, particularly those that are subject to wear. Replace immediately if damaged.
8. Spare parts used must be in accordance with specifications and standards as defined by the manufacturer.
Use only genuine KUHN parts !
9. Before any electric welding is carried out on tractor or attached machine, disconnect generator and battery
terminals.
10. Repairs on elements under pressure or tension (springs, accumulators etc...) must only be carried out by
competentpersonswithstandardizedequipment.
SPECIAL SAFETY RECOMMENDATIONS
1. When changing the machine over from the work to the transport position or vice versa, danger of crushing
and shearing can exist.
Be especially careful and keep all persons away from vicinity of the machine when maneuvering.

Note: The GA 6000 for North America are supplied as standard equipment with a coupling clevis kit and
a ANSI / ASAE 338.4 safety chain (see page 30).
2. P.T.O. SHAFT
Connect the PTO shaft to the 540 rpm (min-1)tractor drive (with the safety clutch fitted on the machine side).
Make sure PTO length is correct :
1° When the PTO is in its maximum extended position, a minimum tube overlap of 300 mm (12") must be
maintained.
2° When the PTO is in its maximum overlap position (retracted), tubes should not butt against the yokes.
Asa safety measurea clearance ofat least2 cm (0.8")must be maintained.If this isnot the case,shorten the
two transmission tubes and the two guard tubes by the same length(fig.A&B).Bevelandcleanthetubes
(fig. C) and grease the inside of the outer tube (fig. D).
3° NeveroperatethePTOattoogreatanangle(30°maximum).
Theserecommendationsandadjustmentsmustberespectedtoavoiddamageorpremature
wear of the PTO.
Never connect the PTO to the 750 or 1000 rpm (min-1)tractor drive.
To avoid accidents which could be serious, make sure that the guards are always correctly
in place and secured with the safety chains provided. On the machine side the safety chain
mustbeattachedaroundoneofthedrawbararms(photo15).Wornordamagedguardsmust
bereplacedimmediately.
