- Once the machine is coupled up, stabilise the drawbar laterally with the device provided for this purpose (bar, chain, chocks, etc.).

2.2 ADJUSTING THE POSITION OF THE CONTROLS

The electric control unit can be mounted in the cab as the user requires. The speed control lever can be mounted either on the tractor or on the machine.

Page 32

2.3 UNIVERSAL DRIVE

- At maximum overlap (with the drive shaft compressed), there must be a safety gap of B = 20mm to prevent the tubes striking the jaws.

- At maximum extension, there must be a tube overlap of A = 330 mm.

- If the above conditions are not met, shorten the tubes and their guards by the same length.

- Round off and clean the tubes and grease the inside of the outer tube.

To avoid the risk of a serious accident, make sure that the universal drive shaft guards are properly fitted and prevented from rotating by the special chains. On the machine side, fasten the chain to the ring (1) located on the header retaining disc on the gearbox. Replace any worn or damaged guard immediately.

2.4.2 Machines without an Auxiliary Hydraulic Unit

In order to power the machines independent distributor, the machine can be connected to the tractor hydraulics in one of three ways:

- Connection to a single-acting distributor and direct return to the tank (strongly recommended).

- Connection to a double-acting distributor. The first port is used to connect the pressure hose and the

second for the return hose. On fitting, make sure that the direction of oil flow is correct.

- Connection to a line from the tractor.

For optimum user-friendliness, it is strongly recommended that the original hydraulic distributor on the tractor be equipped with a continuous pumping position.

The operating pressure of the hydraulic circuit is 190 bar. The minimum and maximum hydraulic oil flow for a standard machine is 30 l/min and 60 l/min respectively.

The pressure and return hoses are equipped with a male push-pull coupler (ISO 7241). The pressure

hose is identified by a white arrow on a red background, pointing from the tractor to the machines hydraulic distributor. The return hose is marked by a white arrow on a blue background, pointing from the distributor to the tractor. Before connecting, make sure that the

couplers are clean. The plastic caps must be used when the machine is not hitched to the tractor.

Once the various hoses have been connected up, make sure that there is no risk of them catching in operation.

When the machine is not hitched to the tractor, all hydraulic hoses must be put back in the special support.

2.4.3 Machines Equipped with an Optional Hydraulic Unit

With this option fitted, the machine is totally independent of the tractors hydraulic circuit. There is therefore no hydraulic connections to be made before the machine can be used.

Page 34

2.4.4 Electric

The machine is supplied as standard with a separate harness to be connected by your dealer to the + and - terminals on your tractor battery (brown wire to + and blue wire to -). A second power cable can be ordered for another tractor under reference A7040170. The electric power cable must be connected directly to the battery for a constant, even electric power supply to the machines controls.

Certain tractors are equipped with this type of 3-pole serial plug. To avoid any malfunctions, the polarity of this plug must be checked.

On mounting the electric power cable, beware of shearing, burning on the exhaust pipe, etc.

Next connect the plug and socket to power the control unit. The electric control unit is fitted with a fuse (see table) and the tractor-side harness with a 30 A fuse (P/N. A7040926).

2.5 PRELIMINARY TECHNICAL CHECKS

This phase is particularly important for your machine to give you full satisfaction. We recommend that you check all of the following points on delivery.

- Check the wheel bolts and tighten up if necessary to 25 daNm.

- Check the conveyor chain tension and adjust if necessary (refer to the Servicing section).

- Check the tightness of the screws and nuts, particularly those holding tools (knives, conveyor bars, etc.).

- Check that the safety labels are fitted and legible.

- Lubricate all moving parts (refer to the stickers for the location of the greasing nipples). Use only manufacturer-recommended grease: refer to the lubricant chart.

- Check the oil level in the gearbox.

- Check the oil level in the conveyor drive unit.

- Check the oil level in the hydraulic unit tank and check the condition of the oil filter (optional).

Page 35

2.6 NO-LOAD TESTS

Before using the machine for the first time under a load, it must be tested to make sure that the tractor-machine combination is in working order. MAKE SURE THAT THERE ARE NO FOREIGN BODIES OR ACCESSORIES INSIDE THE MACHINE.

Procedure

- Make sure that you can change PTO speed. If the machine is equipped with a hydraulic unit, check that the unit can be set to neutral.

As gear shifting is not synchronised, it may be necessary to engage the tractor PTO quickly and operate the gear control lever at the same time.

-1

- Select a PTO speed (270 or 540 min

- Align the tractor and the machine, then engage the PTO drive and leave the tractor idling.

- Gradually increase the engine speed until the PTO speed reaches 540 min

- Start the feed rotor (check that the LED lights up on the control) then the conveyor (test in both directions). Now check that the machine is running smoothly and free from vibration. Reduce the engine speed once again until it is idling.

-1

If the machine is noisy or vibrating abnormally, stop the PTO immediately and refer to the troubleshooting section or contact your dealer. When the problem has been solved, start the test procedure again from the beginning.

- Operate the hydraulically-controlled components and check the operation of the machine.

- Stop the PTO, switch off the control unit and switch off the tractor engine.

Should one of the hydraulic functions fail to work or should it run in the wrong direction, check the hose connections and start the test procedure again from the beginning.

- Finally check that the lighting and singalling equipment (side lights, brake lights and turn-signal indicators) are in good working order.

2.7 UNHITCHING

- Before unhitching the machine, bring the grab inside the body and lower the arm completely (ram rods fully retracted).

- Lay the machine on the ground so that it is stable (adjust the parking stand if necessary).

- Before unhitching the machine, switch off the tractor engine and take the key out of the ignition.

- Uncouple the hydraulic pressure and return hoses and the electrical connections.

- Apply the machines parking brake.

- Remove the hitch safety cable.

- Unhitch.

Page 36

3. MACHINE OPERATION

RECOMMENDATIONS FOR USE

Before carrying out any maintenance on the machine, switch off the tractor engine, take the key out of the ignition, wait until all moving parts are at a standstill and uncouple the universal drive shaft.

3.1 LOADING SILAGE

If the machine is equipped with a hydraulic unit, the speed control unit must be set to neutral.

3.1.1 Approaching the Silage

- Set the hydraulic distributor control lever to the continuous pumping position.

- Raise the arm and grab as far as possible to ensure good visibility and prevent the silage from collapsing as a result of a collision.

- Lower the machine as far as possible without the heel plate scraping the ground then back up to the face of the silage.

- Put the heel plate of the machine on the ground just before coming into contact with the silage.

Note: In the case of a silage clamp, position the machine slightly aslant in order to load as close as possible to the wall.

Never attempt to back your way into the silage by force.

3.1.2 Loading the Machine

Always start by cutting the silage from the top.

- From the tractor cab or the platform, position the grab so as to cut away a chunk of silage about 40cm thick.

- Move the grab back and forth while slowly lowering the arm.

- When the claw is down, bring it back inside the body while raising the arm for optimum loading.

Page 37

- Raise the arm with the grab inside the body and repeat the loading operation until the machine is completely full.

- When the machine is loaded, bring the grab into the

tailgate position without overpacking the silage against the feed rotor.

Never overpack the silage against the feed rotor

3.2 LOADING BALES

If the machine is equipped with a hydraulic unit, the speed control unit must be set to neutral.

3.2.1 Round Bales (1.35 x ø 1.80)

- Raise the arm and the grab for good visibility.

- Back the machine up to the bale and position the heel plate as close as possible to the ground.

- Envelop the bale by fully extending the grab and bringing down the arm until it comes into contact with the bale.

- Keeping the arm in contact with the bale,

back up slowly. When the bale starts to enter the machine body, finish off by combining grab and arm movements.

- Raise the rear end of the machine to keep the

bale inside.

- Raise the arm slightly to decompress the bale.

- Remove the twine then lower the arm again.

Page 38

Note: For easier feeding of hay or haylage or straw blowing with a round bale, we advise you to

make sure that the bale is loaded so that it will unroll naturally. This ensures a better feed through to the turbine - feed rotor assembly and therefore improves the quality of distribution or straw blowing.

3.2.2 Cubic Bales (3 x 1.45 x 1.45)

- Raise the arm and the grab for good visibility.

- Back the machine up to the bale and position the heel plate as close as possible to the ground.

- Fully extend the grab and lower the arm until it comes into contact with the middle of the bale.

- Keeping the arm in contact with the bale, back up slowly. When the bale starts to enter the machine body, finish off by combining grab and arm movements.

- When the bale is loaded into the machine, place the grab to keep the bale in position, without overpacking it against the feed rotor.

- Raise the rear end of the machine to keep the bale inside.

- Raise the arm slightly to decompress the bale then remove the twine.

Note: It is easier to remove the twine once the bale has been loaded with the twine on the side.

Page 39

3.3 REGULATING SYSTEM

The product regulating system, placed above the two feed rotors and at the entry to the turbine, has two working positions:

- A down position to regulate and chop the product. It is essential

that this position is used for feeding hay and haylage.

- An up position allowing the maximum amount of product to

enter the turbine. This position must be used for recycling, feeding silage and straw blowing.

Important Note: When recycling long, fibrous products (hay or

haylage) together with silage, it is advisable to set the regulating system to the down position at the start of mixing to ensure that the product is chopped up adequately.

When a round bale core is used for recycling, it must be recycled alone first of all. The regulators must be kept in the down position.

Page 40

3.4 MIXING

- When loading, start with the fibrous products, then

add the minerals and finish with the silage.

Beware: The addition of fibrous products (hay or straw) increases the volume after recycling.

- Select a turbine speed of 270 min-1.

- Set the regulating system to the up position.

- Put the grab into position with the aid of the index

(1) on the gauge (fig.1).

- Put the shutter and cover into the recycling posi-

tion.

- Hold the control lever for a few seconds until the

operation is completed.

- Engage the tractor PTO and bring the engine to

its rated speed.

- Engage the feed rotor with the conveyor speed

at 0. Then gradually bring it up to between 3 and 4 (the optimum conveyor speed will depend on available tractor power and the nature of the product).

- When mixing is complete, stop the conveyor (set to 0) then the feed rotor, set the shutter and cover

to the feeding position, then disengage the tractor PTO.

3.5 FEEDING

Select the turbine speed according to the product to be distributed:

-1

- 270 min

- 540 min

Note: We strongly recommend against using the machine with a tractor PTO speed of 540 min-1 in

The chute on the right-hand side of the machine (the delivery chute) can be used for two jobs: straw blowing and feeding. To achieve top quality work and to put the forage where you want it, the tip of this chute can be set to one of three positions.

for feeding,

-1

for straw blowing.

economic mode.

Always start the tractor PTO before engaging the feed rotor. Similarly, the feed rotor must be stopped before switching off the PTO. Failure to comply with this procedure is very likely to lead to turbine jamming.

- To adjust the position simply by hand, we recommend opening the chute halfway.

- Take hold of the handle and pull downwards.

- Place the pin in the required notch (the notch farthest away from the machine body corresponds to the most inclined tip position).

Page 42

Operating tips: To stop feedingmomentarily (posts, obstacles, etc.), simply disengage

the feed rotor (the conveyor stops at the same time).

To avoid the risks of jamming in difficult conditions, watch the engine speed. Slow down the conveyor, or even reverse the direction of rotation, as soon as the engine speed drops or the belt begins to slip. In all cases where overloading occurs, it is important to let the feed rotor empty itself before putting the conveyor back into forward motion.

NEVER ATTEMPT TO CLEAR PRODUCT AWAY BY HAND OR USING A TOOL WHEN THE MACHINE IS RUNNING.

When the machine is loaded, we strongly recommend against leaving the conveyor running in reverse longer than is necessary.

Before starting the feed rotor, make sure that the conveyor speed is set to position 0 to prevent a load being fed into the turbine.

3.5.1 Feeding

The rate of product output is adjusted by:

- the variation in tractorengine speed: control of the hydraulic oil flow and PTO speed.

- the conveyor speed.

3.5.2 Feeding Silage

- Start up the tractor PTO and bring the engine up to its nominal speed.

- Switch the tractors hydraulic distributor to continuous pumping.

- Set the regulating system to the up position.

- Point the delivery chute downwards such that the machine wheel does not run over the distributed forage which should be properly channelled towards the ground or into the trough.

- Start up the feed rotor with the clutch (until the indicator lights up).

- To deliver the product, start the conveyor running forwards and adjust the speed.

- Feed the forage regularly onto the conveyor using the grab.

- When feeding is over, bring the arm and grab right in. Stop the conveyor and disengage the feed rotor. Close the delivery chute then disengage the tractor PTO.

Operating tips: The conveyor speed is adjusted by the control unit according to feed speed

and product distribution factors, as well as the type of silage.

Page 43

3.5.3 Hay and Haylage

- Start up the tractor PTO and bring the engine up to its nominal speed.

- Switch the tractors hydraulic distributor to continuous pumping.

- Set the regulating system to the down position.

- Point the delivery chute such that the machine wheel does not run over the distributed forage which should be properly channelled towards the ground or into the trough.

- Start up the feed rotor with the clutch (until the indicator lights up).

- To deliver the product, start the conveyor running forwards and adjust the speed.

- When feeding is over, bring the arm and grab right in. Stop the conveyor and disengage the feed rotor. Close the delivery chute then disengage the tractor PTO..

Operating tips: The rotor will feed the turbine more easily if you allow the bale to rotate freely

under the action of the rotor.

It is preferable to reduce the tractor engine speed when feeding is over to limit projections.

During delivery, it is advisable to raise the rear end of the body to:

- keep round bales up against the feed rotor when the product requires little power,

- facilitate the rotation of round bales against the feed rotor when the product is tougher.

The conveyor speed is adjusted by the control unit according to feed speed and product distribution factors, as well as the type of product.

Page 44

3.6 STRAW BLOWING

- Start up the tractor PTO.

- Bring the tractor up to its nominal speed and switch the tractors hydraulic distributor to continuous pumping.

- Set the regulating system to the up position.

- Point the delivery chute or the optional swivel chute such that the straw is blown where you want it.

- Start up the feed rotor with the clutch (until the indicator lights up if electric controls are fitted).

- To deliver the product, start the conveyor running forwards. The conveyor speed is adjusted by the control unit according to feed speed and product distribution factors, as well as the type of silage.

- Keep the bale in contact with the feed rotor using the grab.

- When feeding is over, bring the arm and grab right in.

- Stop the conveyor and disengage the feed rotor.

- Put the tractors distributor lever back to neutral, disengage the PTO and switch off the engine.

In certain cases, the first fold on rectangular bales tends to shoot upwards at the start of straw blowing. Guides bring the product towards the back of the machine. For this reason, it is important not to stop the conveyor and to let the product drop naturally to the back.

Operating tips: For regular straw blowing, the bale must remain in permanent contact with the feed

rotor without forcing it with the grab.

Raise the rear end of the machine slightly to prevent the core of the bale from being thrown back by the feed rotor.

In the course of distribution, the machine body height can be adjusted in order to:

- keep round bales up against the feed rotor when the product requires little power,

- facilitate the rotation of round bales against the feed rotor when the product is tougher.

We strongly recommend straw blowing after feeding the livestock: this will clean and dry the machine and eliminate the risk of corrosion by acids.

Page 45

Note: Should the turbine or feed rotor become jammed, use the hook mounted inside the housing

on the left-hand side of the machine (see photo below) to pull out the jammed product at the distribution chute or feed rotor, then use a lever to ensure that the turbine can rotate freely.

Page 46

3.7 STORAGE OF CONTROLS

Description: - Auxiliary hydraulic unit

- Driven by tractor PTO

- 22 cm

pump - output at a PTO speed of 540 min-1: 60 l/min.

- 60 litre tank with filter and level gauge

- Circuit protected by valve calibrated to 190 bar

- Recommended oil type: ISO VG 46 (HV); e.g. SHELL HYDRAU PW.

A slight gearing noise may be heard at low speeds. We recommend using the hydraulic unit at a minimum PTO speed of 300 min

-1

Operation:

- Before starting up a machine equipped with a hydraulic unit, check the oil level in the tank.

- Connect and lock the transmission to the tractor PTO and to the pump step-up gear drive shaft.

-1

- The machine must be driven at the nominal PTO speed of 540 min

Under no circumstances use the tractors 1000 min

-1

PTO.

- Start up the tractor, then gradually engage the PTO to operate the pump.

- Try the various machine controls. Check the pump flanges and the various hydraulic connections on the unit for leaks.

Page 48

- With the aid of the speed control lever, the unit may be used in three ways:

- at neutral, therefore without running the turbine, for all loading operations

- with a turbine speed of 270 min-1 for distribution

-1

- with a turbine speed of 540 min

Maintenance:

- Comply with the safety instructions relating to machine maintenance.

- Periodically check the oil level in the tank. The oil level should not be below the top 1/3 of the gauge.

- Change the hydraulic oil after the first 500 hours of work. We recommend an ISO VG 46 (HV) type hydraulic oil. For example: SHELL HYDRAU PW.

- Thereafter, refer to the maintenance chart for the frequency of oil changes.

- To change the filter element, unscrew the plug. Take hold of the filter handle and extract the filter + bowl assembly. To remove the filter, turn 90° anticlockwise and extract it from its cartridge. Clean the bowl.

- Insert a new filter and lock into position by turning it 90° clockwise.

- Screw in the plug and make sure that the seal is correctly repositioned to prevent leaks.

4.2 FREE-WHEEL HOMOKINETIC TRANSMISSION

Transmission assembly providing a greater angle of deflection and free rotation of the turbine.

Before using this equipment, please consult the manual delivered with the transmission.

4.3 WEIGHING SYSTEM

Device used to determine the weight of the ration to be fed to the livestock.

Please read the instructions provided with the weighing system carefully.

Page 49

4.4 SWIVEL CHUTE

Note: The maximum straw blowing distance with the swivel chute is 13 metres.

The swivel chute is an essential item of equipment for farm building with no through access. With its high angle of rotation, straw can be blown to every position while protecting the driver in the tractor cab.

Straw blowing device for distribution to the left and right. The blowing distance is controlled from the tractor cab thanks to an electrically-powered ram (see Description of the Controls).

To avoid improper or incorrect use of the chutes (the swivel chute must not be used to distribute haylage), the machine is equipped with a shutter position indicator.

Shutter set to swivel chute position

Shutter set to delivery chute position

Page 50

Using the optional swivel chute

Athenor recycling machines with a swivel chute are fitted with a valve under the machine platform (Photo 1). This valve is used to open and close the recycling cover. If it is open, the cover and shutter switch to the recycling position. If it is closed, only the shutter switches to the recycling position.

4.5 MIXING HOPPER

Mixing hoppers with a capacity of 575 litres can be used to add minerals and concentrates to the coarse forage (maize or grass silage, etc.). Blending takes place in the turbine.

Thanks to its low profile and its two side filling ports, the hopper can easily be loaded without any special accessories. For maximum accessibility, it is advisable to lay the machine on the ground and lower the tractors lifting mechanism right down when the machine is coupled to the drawbar.

Page 51

5. MAINTENANCE

Before carrying out any maintenance, servicing or repair work or when investigating the cause of failure or malfunction, you must switch off the engine, lay the machine down, remove the ignition key and wait for the moving parts to come to a complete standstill.

Before proceeding with any maintenance work on a machine in the raised position, prop up the machine with an appropriate support.

(1)

Before any maintenance operation calling for work inside the body, raise the machines arm and grab and lock the arm by positioning the lever (A) of valve (B) perpendicular to the ram (position 1).

Remember to release the arm at the end of the operation.

When clearing a blockage or replacing a working part, wear protective gloves and only use appropriate tools.

Beware! Never pass between the feed rotors to access the turbine.

To avoid environmental contamination, it is forbidden to throw away or dump any type of oil, grease or filter. Hand them over to collection firms.

Before carrying out any operations on the electric circuit, disconnect the power source (tractor charging circuit or battery).

Any protective devices liable to wear should be checked regularly. Replace them immediately if they are damaged.

Spare parts must comply with the standards and specifications laid down by the manufacturer. Only use Kuhn spare parts.

Before carrying out any electric welding work on the tractor or towed machine, disconnect the cables from the alternator and battery.

Check the tightness of screws and nuts regularly. Tighten up if necessary.

Page 52

5.1 GREASING

The greasing points are identified by a label featuring a white grease pump on a blue background. Some grease nipples are located under guards or protective caps. We strongly recommend that you take the time when your machine is delivered to open all of the guards to identify the various greasing points. Remember that regular greasing will increase the life of rotating parts considerably.

5.2 CLEANING THE CONVEYOR

For cleanliness, the conveyor is housed in a case. In order to eliminate the build-up of product from the bottom of the case, it is preferable to open the shutter once a week.

The following procedure should be applied:

- Shift the original tractor distributor lever to the continuous pumping position.

- Switch on the tractor PTO and engage the feed rotor.

- Start the conveyor in forward motion for a few seconds to bring the built-up product to the back of the

conveyor case.

- Stop the conveyor and disengage the feed rotor followed by the tractor PTO.

- Switch off the tractor engine and remove the key from the ignition.

WAIT FOR A FEW MOMENTS UNTIL THE MACHINE IS AT A COMPLETE STANDSTILL.

- Pull the locking handles (A) located on either side.

- Release the hooks holding the ring (B).

- Fully open the shutter (C).

- Using a brush or similar tool, remove any product that may be left behind.

- Lift the shutter and insert the two hooks into the ring. It is important to hook the rings before lifting the handles.

- Lift the handles to lock the shutter.

Page 53

5.3 CHAIN TENSION

The tension of the chains should be checked after every 100 hours of operation. If the deflection exceeds 150 mm, the chains need to be tightened up.

Never fully tighten the chains. Always leave a deflection of at least 50 mm (Figure 1).

Procedure:

Open the shutter (C on photo opposite) according to the procedure described for conveyor cleaning.

Figure 1

- Loosen check nut (D).

- Tighten up nut (E).

- Tighten check nut (D).

- Make sure that both sides of the conveyor are tightened by identical amounts.

- Close the shutter as described in the section on conveyor cleaning.

Note: When the chain tension adjuster has reached its limit of travel, the left and right-hand chains

can be shortened by two links.

Page 54

5.4 ADJUSTING BELT TENSION

In order to guarantee optimum system operation, belt tension needs to be checked and adjusted if necessary every 100 hours, or more often if difficult products are frequently distributed.

Belt tension is adjusted using the screw rod (A), nut (B) and check nut (C).

In the engaged position, the end of the spring should be level with the indicator (

Left-hand side drive (lower feed rotor)

I).

Right-hand side drive (upper feed rotor)

Page 55

5.5 CHECKING AND ADJUSTING THE SECTIONS

Check the position of the regulating tines in relation to the sections regularly.

- Outer regulating tines (A): these tines must be centred in relation to the sections passing on each side.

- Inner regulating tines (B): the distance d between these tines and the sections must be less than 10 mm. The non-bevelled side must be facing the regulating tine to cut the product correctly.

A A

To adjust the position of the regulating tines in relation to the sections, add or remove shims (C) (Ref. A5204400).

For this separating system to work efficiently, the sections must be sharp:

grind or replace them if necessary.

You can swap the sections around in order to use both cutting edges of each section.

Page 56

5.6 STORAGE

If the machine is not to be used for a long period, prepare it for storage as follows:

- Clean the body (inside, outside and underside), the arm and the grab. Remove any product build-

up. If necessary, repaint any surface in danger of rusting. Grease the underbody.

- When using a pressure cleaner, pay attention to the sensitive areas (ram joints, electrical

connections, etc.).

- Bring the ram rods right in to protect them from moisture and dust.

- Grease the drive chains.

- Check that the belt is slack.

- Clean all greasing points and joints. Grease.

- Where possible, store your machine in a sheltered area on blocks to protect it from ground damp.

- Check tyre pressure and wheel bolt tightness.

6. TROUBLESHOOTING

Problem What to do

l Insufficient grab power - Check that the hydraulic connections between the

tractor and the machine are correct (pressure and return).

- Check the hydraulic pressure (190 bar) and the pump output (35 l/min). The return pressure must be 8 bar maximum at the nominal tractor speed.

l Hydraulic functions fail - Check that the hoses are correctly connected to the

to operate tractor distributor (make sure that the valves are opening

as dirt can hinder correct operation).

- Make sure that the voltage provided by the battery is over 11 V.

- Check that the original tractor distributor is set to the continuous pumping position (except with auxiliary hydraulic unit).

- Check that the control unit is switched to 1 or 2.

- Check that the control unit power cable is plugged in.

- Check that the battery power is reaching the socket.

- Check the polarity of the socket.

l The conveyor fails to run - Check that the feed rotor is engaged and the indicator is

lit (see section 1.6 Description of the Controls).

- Open the left-hand side hood and check that the belt tension roller ram rod is fully retracted.

- Check that the circuit breaker sensor on the feed rotor clutch is activated.

The sensor mounted on the feed rotor clutch ram prevents conveyor operation if the feed rotor is not engaged. The photograph opposite shows the position of the clutch ram when the feed rotor is rotating.

It is essential that the clutch ram rod is fully retracted for the circuit breaker sensor to be activated.

l The conveyor stops rotating in the course of work

- Check the hydraulic connections for leaks.

- Check that the feed rotor is engaged and the indicator is lit (see section 1.6 Description of the Controls).

l The feed rotor and the conveyor

stop rotating in the course of distribution

l Turbine fails to rotate and - Check that there is no product build-up in the turbine. overload clutch slipping If this is the case, use the hook mounted on the left-hand side

- Check the hydraulic connections for leaks.

- Check that the indicator is lit (see section 1.6 Description of the Controls).

- Check that the clutch is fully engaged (ram rod fully retracted, see photo above). If not, make sure that the clutch ram does not have an internal leak.

of the machine to pull out the jammed product at the delivery chute or feed rotor, then use a lever to ensure that the turbine can rotate freely. Once released, run the turbine empty for a few seconds until it reaches its normal working speed.

You can also gain access to the turbine interior via the flap (A) on the front of the machine.

Should the turbine become jammed, a special hook must be used to unblock it (see page 44). In view of the high inertia of this system, forcing the turbine disc to move manually can lead to serious risks of having a finger severed by a blade.

- Make sure that the product to be distributed is not packed against the feed rotor. Release the pressure on the product inside the machine body by opening the grab slightly. It is also possible to switch the conveyor briefly to reverse and then back to forward motion.

l Turbine rattling when PTO engaged - Engage the PTO gradually at the recommended

speed. If the tractor is equipped with a hydraulic PTO clutch, contact the dealer to solve the problem with the progressive clutch rate irrespective of tractor engine speed.

l Arm lowered too slowly or too - The arm lowering speed can be adjusted by the flow

Note: The arm raising/lowering speed is adjusted at

the factory to achieve two identical speeds.

- Unscrew the check screw.

- Turn the wheel to the right to reduce the flow and, in turn, the lowering speed.

- Turn the wheel to the left to increase the flow and, in turn, the lowering speed.

- Tighten the check screw.

An excessive arm lowering speed can damage the arm and the rubber stops on the machine body, or even the body itself.

l Belt driving the beater bar slipping for no apparent reason.

- Check the belt tension (see section 5 Maintenance).
