Make sure that you are familiar with all equipment and controls as well as with their functions before you begin working with the machine. Während des Arbeitseinsatzes ist es dazu zu spät!

5

6

7

The user should wear tight fitting clothes. Locker getragene Kleidung vermeiden.

Keep the machine clean to prevent the danger of fire!

Before starting or moving the machine, make certain that nobody is in the vicinity of the machine! (Watch for children!) Make sure that you have a clear view!

8 You may carry passengers during operation and transport on the working implement only if they use the passenger seat provided.

9 Couple implements correctly! Attach and secure implements to specified devices only!

10 When attaching or detaching implements, place the supporting devices in the correct positions!

11 Use extreme caution when attaching or detaching implements onto or from the tractor!

12 Always attach ballast weights properly to the fixing points provided!

13 Observe permitted axle loads, gross weight and transport dimensions!

14 Check and install transport equipment, such as lighting, warning devices and protective equipment!

15 Actuating mechanisms (cables, chains, linkages etc.) for remote controlled devices must be positioned in such a way that no movements are unintentionally triggered in any transport or working positions.

16 Ensure that implements are in the prescribed condition for on-road travel and lock them in place in accordance with the manufacturer's instructions!

17 Never leave the driver's seat when the vehicle is moving!

18 Always drive at the correct speed for the prevailing driving conditions! Avoid sudden changes in direction when travelling uphill or downhill or across a gradient!

19 Hitched implements and ballast weights effect the driving, steering and braking response of the machine. Make sure that you are able to brake and steer the machine as required!

20 Take into account the extension radius and/or inertia of an implement when turning corners!

21 Start up implements only when all safety devices have been attached and set in the required position!

22 Keep safety equipment in good condition. Replace missing or damaged parts.

23 Keep clear of the working range of the machine at all times!

24 Do not stand within the turning and swivel range of the implement!

25 Never operate the hydraulic folding frames if anyone is inside the swivel range!

18

Safety

26 Parts operated by external power (e.g. hydraulically) can cause crushing and shearing injuries!

27 Before leaving the tractor, lower the implement onto the ground, apply the parking brake, switch off the engine and remove the ignition key!

28 No one should stand between the tractor and the implement unless the vehicle has been secured against rolling by means of the parking brake and/or wheel chocks!

4.6 Attached devices

1

2

3

4

Use extreme caution when attaching or detaching implements onto or from the tractor!

Couple the respective application devices to the appropriate couplings (e.g. three-point suspension) only and secure them in a way (transport, use) that excludes inadvertent lifting or lowering of the device.

When using three-point linkage, the attachment categories of the tractor and the device

(e.g. PTO speed, hydraulic system) must be coordinated!

When using the outside controls for the three-point linkage, do not step between the tractor and the device (risk of injury)!

19

Safety

4.7 PTO operation

1

2

Use only PTO shafts specified by the manufacturer!

The guard tube and guard cone of the PTO shaft and the PTO guard must be attached and in good working condition (on the implement side, too)!

3 Make sure that the required tube covers are in place for PTO shafts in transport and working position!

4 Before installing or detaching PTO shafts, disengage the PTO, switch off the engine and remove the ignition key!

5 When using PTO shafts with an overload safety or free-running coupling which are not shielded by the guard on the tractor, mount the overload safety or free-running coupling on the implement side!

6

7

8

Always make sure that the PTO shaft is properly installed and secured!

Attach chains to prevent the PTO shaft guard from rotating with the shaft!

Before switching on the PTO, make sure that the selected PTO speed of the tractor matches the permissible implement speed!

9 Before switching on the PTO shaft make sure that no person is in the danger zone of the device!

10 Never switch on the PTO if the engine is switched off!

11 No one should be in the vicinity of the rotating PTO or PTO shaft when the PTO is in use.

12 Always switch off the PTO shaft when the angle is too large or the PTO shaft is not required!

13 Caution! After disengaging the PTO danger due to the flywheel running on! Keep away from the implement during this time. The machine may be worked on only if it is completely at standstill and if the flywheel is secured by the parking brake.

14 Cleaning, lubricating or adjusting PTO driven implements or the PTO shaft only with PTO disengaged, engine switched off and ignition key withdrawn! Secure the fly-wheel with the parking brake.

15 Place the disconnected PTO shaft onto the support provided!

16 After detaching the PTO shaft, attach the protective cover to the PTO end!

17 If damage occurs, correct this immediately before using the implement!

Note

The instructions of the manufacturer must be observed with regard to the PTO shaft. (separate operating instructions)

Before placing the machine in winter storage, clean inside and outside thoroughly. If you use a high-pressure cleaner to do this. do not keep a stream of water directed at bearing points. After cleaning is completed, lubricate all lubrication points. Do not wipe off any grease that comes out of bearing points. The hardened grease will provide additional protection against moisture.

Oil all joint points!

Check all movable components such as deflector rollers, joints, tension rollers, etc. to make certain they move easily. If necessary remove, clean, grease and remount. If necessary, replace with new parts.

Use only original KRONE replacement parts.

Disassemble the PTO shaft. Lubricate the inner tubes and the guard tube with grease. Grease the lubrication points on the cross joint and on the bearing rings of the guard tubes.

Touch up damaged paint and preserve all uncoated areas thoroughly with rust protection agent.

Park the machine in a dry location, but not in the vicinity of artificial fertilisers or livestock buildings.

Perform the necessary repair tasks during the time immediately after the harvest season. Draw up a list of all replacement parts you will need. This will make it easier for your KRONE dealer to process your orders and you will be certain that your machine will be ready for use at the beginning of the next season.
