Safety

1 Any operator, service man and owner must be familiar with the warning instructions for themachine in this manual, before operations commence.

Always work carefully with agricultural machinery. Read through and observe the safety instruc-tions in this manual. Safety is your responsibility.

Pay particular attention to this symbol. It means that there could be a serioushazard. It emphasises precautions which have to be complied with in order to preventaccidents.

This symbol can be found throughout this manual and on the warning signs on themachine. They are for your safety and should be observed at all times.

General safety instructions

2 Be careful when other people or animals are close by! Never start up the machine when peopleor animals are close or on the machine or tractor. Never stand between the tractor wheels andthe machine.

Adhere to the local laws regarding children's minimum working age with agricultural machinery.

3 Use of the machine. The machine must only be used for harvest of common grass crops. Themachine must not be used for harvest of maize.

4 Use personal protection devices. Do not wear loose clothing which might catch in any of themoving parts. In dusty conditions a suitable mask to EN 149 must be used.

Take care of excessive sound level. Certain tractor/implement combinations, dependant on operat-ing conditions, may generate a noise level in excess of 85 dB at the operators ear, even in a 'Q' cab.

In these circumstances ear defenders must be worn. Keep cab windows and doors CLOSED atall times to reduce noise level.

5 The machine must only be coupled to a correctly sized tractor.No other machines or implementsmust be coupled. The relationship between tractor weight and machine weight must be correct.Local regulations governing this relationship must be observed.

Make sure that the tractor has the correct P.T.O. A machine intended for 540 r.p.m. P.T.O. inputspeed must never be coupled to a tractor with 1000 r.p.m. P.T.O. output speed.

6 Coupling of tractor and machine must be carried out as laid down in the instructions. All draw-bar pins must have locking split pins. Observe all local laws regarding road transport, - please notethat some countries require the use of safety chains.

7 Work in a safe way. The tractor engine must ALWAYS be stopped and the ignition key removedbefore carrying out repairs, cleaning, lubricating or maintaining the machine.

1 Safety guards. Make sure that ALL GUARDS are in good order and fitted correctly. Do notattempt to start the machine before ensuring this.

Pay particular attention to the plastic guards of the P.T.O. shaft. If damaged they must be

replaced. The chain locks of the guards MUST always be fitted on a suitable place on the tractorand the machine to prevent the outer plastic guards turning around.

2 Hydraulics. Be very careful when dealing with hydraulics. Use eye protection and gloves. Escap-ing hydraulic oil under pressure might penetrate into the skin and cause serious infection. See adoctor if you have been exposed to injury.

Take care that nobody is close to the machine when the hydraulic functions are being operated.

3 Remember when uncoupling, and when leaving tractor/machine. When uncoupling, all hy-draulic functions must be in neutral position. The machine must be lowered to the ground and besafely secured. Place backstop at the wheels of the machine. Never allow children to play or evenstay near agricultural machinery.

4 Drive safely. Beware of your responsibility, - carelessness or slovenliness can cause serious inju-ry or death.

When the machine is in operation: Pay attention to the fact that TA 336 - 337 in hilly groundconditions can be unstable in raised position. This can be abated by fitting a balancing weight inthe left hand side (optional equipment, - see page 41).

Before transporting on public roads: Always check that wheel-fixing bolts are tightened, thatthe coupling is in order, and that hydraulic systems and pawls are locked, see the manual of themachine. Drive carefully. Reduce speed when turning and driving on uneven ground, - take carethat machine is not swinging and becoming unstable.

Be aware of the danger of overturning when working on slopes or soft ground.

The machine must not be used in situations that can make the tractor unstable.

5 Lighting. It is the responsibility of the owner/operator to provide correct lamps and reflectors onthe machine, when it is being transported on public roads during lighting-up time. Observe thelocal laws.

6 Safety equipment. Always carry first aid equipment on the tractor. Also observe the local legisla-tion concerning fire extinguishers. When working with hay or straw a fire extinguisher must beavailable at all times.

7 Spare parts. For safety reasons use only original spare parts. If injury occurs when using non-original spare parts the Kverneland warranty is invalidated.

8 Maintenance. Take care that the machine is properly maintained and kept in good safe workingcondition. Never change the technical constructions of the machine.

New machine, - be careful

1 Read the directions for use. Great care must be taken, when starting up a new machine. Incorrectmounting, wrong operations etc. can result in expensive repairs and loss of profits. Kverneland'sfactory guarantee is annulled if the instructions of this manual are not adhered to. The machinemust be assembled in accordance with the special assembly instructions supplied with the machine.

Pay particular attention to this symbol, - it emphasises operations where great caremust be taken in order to avoid incorrect mounting, wrong operation etc.

Be especially attentive to the following when starting a new machine.

2 Check that the machine is mounted correctly, and that it is not damaged. Be certain that the hy-draulic hoses are mounted so that they are long enough to allow for cylinder movements.

3 Be very careful when fitting the P.T.O. shaft. If the P.T.O. shaft is too short or too long it can causegreat damage to the machine and tractor.

If the P.T.O. shafts of the machine are noisy or vibrating the fitting instructions must be repeated,

- see page 27 and 31.

4 The machine is equipped with a friction clutch which must be maintained as shown in this opera-tor's manual. The clutch must not be blocked or in any way functionally by-passed, either partiallyor completely.

Note: Before starting a new machine, the friction clutch must be bled - see page 45.

5 The machine gear is marked by a label, shown at A. This label may be red, green or blackdepending on the type of drawbar fitted. Check that the machine has the correct type of gear fitted- see page 25 (swivel hitch) and page 29 (wide-angle hitch).

6 Before starting up a new machine it must be lubricated. Check that cutterbar, angle gear andgearbox (swivel hitch) are filled with oil and that the oil level is correct. Use only the oil gradesprescribed in the manual.

7 Check that all bolts at cutting discs and rotor are tightened before the machine is started.

Check and re-tighten all bolts on the machine after the first hour of operation. This is especiallyimportant for fast rotating parts. Also re-tighten after service work has been carried out.

*) On TA 338 C models, the friction clutch is located on the lateral power transfer shaft betweenthe bevel gearbox and main gearbox, - see page 50, photo 8.

Function

The cutterbar cuts and throws the crop into the conditioning rotor. Which in turn throws the cropbackwards into the swath deflector plates. These plates form the crop into a swath approx. 1.3 mwide (adjustable).

The conditioning effect can be regulated in two ways. The distance between the conditioningplate/rotor is adjustable and the rotor can be operated at two different speeds.

The machine has an excellent ability to follow the ground contours. The machine frame withcutterhead/conditioner is suspended by two heavy springs so that it floats easily. The cutterbar isseparately suspended within the cutterhead frame and is free to float independently.

The stubble height can be adjusted, without steps, by adjustment of the cutterbar's cutting angle.

The drawbar cylinder can be used during operation to manoeuvre the machine around obstacles.Sharp turns may be made without overloading the power transfer shaft if the machine is fitted withswivel hitch.

Mounting - coupling

1 - 2 Checking of gearbox and wheel support

Check that the machine is fitted with a main gearbox suitable for a swivel hitch. The gearboxlabel, shown at A, must be green. This does not apply to 338 C which does not have a label.

Check that the machine lifting cylinder is fitted correctly in the wheel suspension. The bottomposition N is for machines with low cut skids, unless the machine is fitted with wheels size 7.00x 12 in which case position P must always be used.

Always use position P for high cut skids and for machines fitted with wheels size 7.00x 12.

3 - 4 P.T.O. 540 or 1000 r.p.m. selection

The swivel gearbox B can be mounted in two ways, to accept either P.T.O. 540 r.p.m. or 1000r.p.m., input speed. The gearbox is mounted from the factory for P.T.O. = 1000 r.p.m. inputspeed.

If the P.T.O. input speed is to be altered for P.T.O. = 540 r.p.m. the gearboxes must be removed andturned through 180o so that the former input gearbox becomes the output gearbox and the formeroutput gearbox becomes the input gearbox. The breather plugs have to be moved to the top posi-tion on both gearboxes.

If possible a gearbox for P.T.O. = 1000 r.p.m. should be used. This is especially important if thetractor has over 70 kW at the power transmission (a high number of revolutions = lower torque atthe P.T.O. shaft).

The two splined shafts of the gearboxes have been marked from the factory with a label as shownat C. Before starting up a new machine check that the gearboxes are mounted for therequired P.T.O. input speed, see page 60.

It is dangerous to couple a tractor with P.T.O. = 1000 r.p.m. to a machine mountedwith swivel gearbox for P.T.O. = 540 r.p.m.

5 - 6 Coupling with the lifting arms of the tractor

Adjust the right lift arm D to the same height as the left lift arm. The drawbar E should beswung aside or removed.

Mount the machine to the tractor's lift arms and tighten stabilizer chains F, or fit stabilizingstruts.

Coupling between machine and tractor must be carried out according to directions.The two linkage pins must be securely locked with heavy retaining clips. If the ma-chine becomes disconnected from the tractor it could cause severe damage or death.

1 - 2 Height of drawbar

Adjust the machine's drawbar height by means of the tractor's link arms. Set the drawbar as hori-zontally as possible, taking the following into consideration:

Check that the difference in height between the tractor's and machine's P.T.O. shafts is notexcessive, - the P.T.O. shaft angles must be a maximum of 15o when the machine isoperating.

If the tractor is unable to keep the link arms in the required position, lock them by means of chainG as shown.

Automatic depth control (draft) must no be used. If this device cannot be disengaged it must beblocked. See the tractor's manual.

3 - 4 P.T.O. shaft "tractor - swivel hitch"

Before fitting the P.T.O. shaft check the length in the following way:

Adjust the tractor link arms so that the machine and tractor P.T.O. shafts are level then fit thetwo halves of the shaft on both the tractor's and machine's splined shaft.

Note: If the tractor with P.T.O. = 1000 r.p.m. is equipped with 21 splined P.T.O. shaft, thestandard 6 splined yoke must be replaced. Order number is shown in machines spareparts list (optional equipment).

Hold the two P.T.O. halves together as shown on photo 3 and mark the correct shaft length(about 25 mm of clearance). Note: On most tractors it is not necessary to shorten the shaft at all.

When shortening the shaft the same length of all 4 parts a - b - c - d must be cut off. Be verycareful when shortening, - the inner profile tube of the shaft is coated with RILSAN and mustnot be damaged. Do not use an angle grinder to cut the shaft!

The shaft ends should be cleaned off with a file and finished with an emery clotch. This isespecially important for the outer tube. Otherwise the coating ofRILSAN may be "scrapedoff". Remove all metal filings and lubricate the profile tubes with Molybdenum grease or equiva-lent.

5- 6 Hydraulic connection

Connect the hydraulic hoses from the drawbar cylinder to a set of double-acting oil connectionsand connect the hose from the lifting cylinders to a single-acting oil connection. Ensure that thesingle-acting oil connection can be used for a remote cylinder and can be secured in the raisedposition, - see the tractor manual.

Note: When lifting a new machine hydraulically for the first time the left side of the machinewill lift to the maximum before the right side. At the same time as lifting the right hand

side it might be necessary to bleed the cylinder, shown at H.

Be careful when operating with hydraulics. Always use eye protection and gloves.Escaping hydraulic oil under pressure might penetrate the skin and cause seriousinfection. Call for a doctor if a person is exposed to injury.

Mounting - coupling

1 - 2 Checking gearbox and wheel support

TA 338 C cannot be fitted with wide-angle hitch.

It is dangerous to couple a tractor with a 1000 r.p.m. P.T.O. to a machine fittedwith a gearbox for 540 r.p.m. P.T.O.

Check that the machine lifting cylinder is fitted correctly in the wheel suspension. The bottomposition N is for machines with low cut skids, unless the machine is fitted with wheels size 7.00x 12 in which case position P must always be used.

Always use position P for high cut skids and for machines fitted with wheels size7.00 x 12.

3 - 4 Tractor drawbar

The tractor drawbar must not be offset and must be fitted with a fork as shown at B. The clevisC must be fitted with a retaining pin. If the tractor cannot be fitted with a fork, use optionalequipment No. 45.356.300, as shown in illustration 4.

Coupling of machine and tractor must be carried out according to directions. If themachine becomes disconnected from the tractor it could cause severe injury or death.The tractor drawbar must be fitted with a fork and the clevis must be fitted with aretaining pin. Observe local regulations concerning trailer coupling.

5 - 6 Height of drawbar

The height of the drawbar can be altered by means of an adjustable drawbar mounting D asshown. The drawbar should be as horizontal as possible taking the following into consideration:

Check that the difference in height between the tractor's and the machine's P.T.O.shafts E and F is not more than 80 mm. Otherwise the P.T.O. shaft will oscillatein rotation and hereby overload the machine's transmission.

1 - 3 P.T.O. shaft "tractor - machine"

IMPORTANT: The P.T.O. shaft's wide angle joint R must be placed at the tractor end.

Adjust the tractor's and machine's drawbar according to the schedule on photo 1. Choose an ad-justment where the P.T.O. shaft is as long as possible (by extending the tractor's drawbar).

Before shortening or fitting the P.T.O. shaft check the length in the following way:

Drive forward with both tractor and machine with correctly adjusted drawbar. Turn sharp to theright until the maximum turning angle is achieved,- fit the two "loose" half parts of the P.T.O. shafton both tractor and machine, - hold the half parts of the shaft together and check the shorteninglength.

Drive forward with the tractor, - hold the shafts together again and ensure that the P.T.O. tubeswould have an overlap of at least 120 mm after shortening.

Shortening of the P.T.O. shaft:

When shortening the shaft cut the same length off all 4 parts a - b - c - d. Be very careful whenshortening, - the inner profile tube of the shaft is coated with RILSAN and must not be damaged.Do not use an angle grinder to cut the shaft.

The shaft ends should be cleaned off with a file and finished with an emery clotch. This is espe-cially important for the outer tube. Otherwise the coating of RILSAN may be "scraped off".

Remove all metal filings and lubricate the profile tubes with Molybdenum grease or equivalent.

The following warning must always be observed:

Be careful when turning sharp to the right. With some tractor types the P.T.O. shaftcan "bottom" and thereby damage the shaft and/or other parts of the machine ortractor.

Maximum turning angle for the wide angle P.T.O. shaft is 80o. Otherwise the wide angle joint and/or the tractor's P.T.O. shaft will be damaged.

4 - 5 Hydraulic connection

Connect the hydraulic hoses from the drawbar cylinder to a set of double-acting oil connectionsand connect the hose from the lifting cylinders to a single-acting oil connection. Ensure that thesingle-acting oil connection can be used for a remote cylinder and can be secured in the raisedposition, - see the tractor manual.

The right hydraulic cylinder must be bled before starting up a new machine, - see page 27 below.Also note existing safety regulations.

Operation - adjustment

1 Cutting height - spring suspension

The cutting height is adjusted by changing the cutting angle of the cutterbar A. Adjustment isfrom 4o to 8o inclination angle which corresponds to a stubble height of 25 mm to 40 mm (variablewithout pre-set steps).

The pivot point of the cutterbar is shown at B. Change of the cutterbar angle is carried out bymeans of a screw adjusted wedge C. Note: The wedge only limits the cutterbar's movementdownwards, - if the bar meets an obstacle it will raise to the horizontal position while passing over

the obstacle.

The machine's cutterbar and conditioning unit are suspended by two springs D and kept in posi-tion by connecting arms E and M. The springs have a bottom stop which is activated whenlifting the machine.

2-3 Cutting height:

The machine must be placed on even ground. It must be coupled to the tractor correctly. Thedrawbar must be set in the working position.

Adjust the cutting height with the screw adjuster wedge F. Choose for example mediumstubble height = 30 mm, - this corresponds to an adjuster screw measurement of 150 mm asshown.

If a reduced stubble height is required, an adjustable connecting rod can be fitted at the lower rightside of the machine, optional equipment - see page 39.

Use the highest cutting height when operating in fields with many stones and/or fitthe high cut skids below the cutterbar (optional equipment, - see page 39).

4 - 5 Spring suspension:

Tighten the left and right balancing spring G. Check the spring adjustment by lifting themachine as shown at L on both left and right sides. Tighten the springs until the force re-quired to lift is 30 - 40 kg on both sides.

Note: Normally the springs are not be tightened equally (as they are each of different specifi-cation).

Drive into the field, - check that the cutterbar's pressure against the ground is as lowas possible. If the stubble is uneven/wavy the sprngs are tightened too much.

Always lock the spindles of the springs with their locking plates to prevent move-ment so that the adjustment dont change. When changing cutting height it will alsobe necessary to re-adjust the balancing springs.

Note: The right hand cylinder can be adjusted in the length at E. Adjust the cylinder if the mainframe of the machine is not parallel to the ground.

Maintenance

1 During all service operations involving knives and cutting discs the tractor enginemust be stopped, the hand brake activated. If the machine has been raised, the safetydevices S must be fitted to the lifting cylinders on the left and right hand sides.

Re-tighten the bolts of the cutting discs and knife holders on your new machinebefore starting and again after about 1 hour of operation. The same applieswhen any service work is done, for example replacing knives.

2 - 5 Friction clutch (1450 Nm)

TA 336 - 337 - 338 - 339: The machine friction clutch A is located under the drawbar. TA 338C:The friction clutch is located at G. Ensure that the friction clutch, which has a built-in freewheelfunction, is in good operating condition.

The clutch is not to be blocked or otherwise fully or partly put out of action. Other-wise the factory guarantee is annulled.

To prevent unnecessary stress on the friction clutch and transmission the tractor'sP.T.O. speed of 540 or 1000 r.p.m. must be maintained. Too low a P.T.O. r.p.m. willload the friction clutch unnecessarily, and it will be overheated and worn rapidly. Ifthe clutch is overheated the friction discs may be damaged and will require replace-ment.

Before starting up a new machine and after long storage the friction clutch must be freedand checked in the following way:

Loosen all bolts C, 5 turns.

Block the cutterbar to prevent turning with a wooden chockD placed between 2 cutting discsthat run toward each other.

Start the tractor and let the clutch rotate freely until it gets handwarm. Stop the tractor, re-tighten all bolts and remove the wooden chock.

The torque setting of the friction clutch is approx. 1450 Nm. The spring adjustment of the clutchis pre-set, - the springs cannot be adjusted. Replace the friction discs B when it is estimated thatthe torque setting of the clutch is too low.

6 Universal joint

Check universal joint between the gearbox and the cutterbar 2 - 3 times per season. Bolts E mustbe locked with LOCTITE 242. See also page 67.

1 - 3 Knives - cutting discs

The machine's guard B can be raised so that there is free access for inspection of cutting discsand knives.

Check daily that the bolts of the cutting discs and knives are tightened, and thatcutting discs, cones and knives are undamaged. If the rotating parts are unbalanced,vibrations could occur causing damage to the cutterbar. Damage of this kind annulsthe guarantee.

Keep the cones C on the right hand and left hand side clean, clean them inside 2 - 3times per season. If the cones are unbalanced, vibrations could occur causing damageto the cutterbar. Damage of this kind annuls the guarantee. Check the universal joint,- see page 45.

Damaged knives H must be replaced at once. If the knives are worn on one side only they can beinterchanged by using the knives from the next disc in order that the knives may be used on bothsides. Check that bolts J and nuts G are O.K. - if not they must be replaced.

Note: The knives have to be in the position shown F, to remove the bolts.

Only use original spare parts. The machine's cutting discs rotate at 3000 r.p.m., -never make a compromise with safety.

Operate with safety, - note the following:

Fit the cutting discs in pairs as shown (90o displacement of knives).

Always use LOCTITE 242 on the bolts of the cutting discs K. Tightening torque as shown. Ensure that mating faces are clean and free from dirt.

Special for TA 337 and TA 339: The outermost left hand cutting disc is different from theothers, - see the spare parts list of the machine.

Special for TA 338 and TA 338 C: The outer discs on the right and left hand sides are differentfrom the rest - see spare parts list of the machine.

1 - 5 Oil - cutterbar

The easiest daily oil check can be carried out on an area known to be level. This means that itwould only then be necessary to check once that the cutterbar is actually level each time in the wayshown in photo No. 2 and 3.

The following operations must be carried out in a safe and secure way. During allwork near the machine's cutting discs the tractor engine must be stopped and theP.T.O. shaft disconnected.

Do as follows:

Drive the machine to an area of level ground. Raise the machine and place a wooden blockA(about 240 mm high) under the cutterbar. Lower the machine onto the block as shown on ill. 1(with high cut skids, block height should be approx. 200 mm).

Check the position of the cutterbar with a spirit level as shown in B. The bar must be quitelevel in this direction. If necessary correct the position of the block to the right or left side.

Check also that the cutterbar is fairly level in the driving direction, shown at C. If the spiritlevel indicator is in extreme position (max. +/ 1,5o) the position of the cutterbar must beadjusted, for instance by changing the height of the drawbar.

Remove the oil filler plugE. It is situated between the second and third disc on the machine'sleft hand side. Wait for 3 minutes (if the oil is cold: Wait for 15 minutes) and check the oil levelusing a steel tape measure as shown in F. Amount of oil from minimum to maximum is about1 litre which equals 3 mm difference in depth.

1 - 3 Cutterbar

Be particularly attentive in checking or repairing the cutterbar, - it rotates at 3000

revs per minute. Take care that worn bearings and gear wheels must be replaced intime. Otherwise a single damaged bearing might cause damage to the whole cutter-bar. Use LOCTITE when stated, - hardening time approx. 15 minutes.

Generally when replacing bearings:

Use the correct back-stop when pressing new bearings into the gear wheel/bearing housing. Onlypress the bearing ring which is pressed into the gear wheel/bearing, - otherwise new bearingsmight be damaged when fitting.

Order No. for tool set and repair set, - see spare parts list.

Intermediate gear (Illustration 1)

Inspection of intermediate gear can be carried out through the collar bearing's holes. Intermediategears can only be dismantled through opening in the right hand side of the cutterbar, but gear atL on TA 337 - 338 -338 C - 339 and at R on TA 338 - 338 C can be removed through the collarbearing hole. These gears are smaller than the other. Note the following when replacing thebearings:

When pressing out the bearing, sealing ring A is pressed into pieces. Use a new sealing ringwhen fitting a new bearing.

Check that the gaskets B and D is not damaged. The thread surfaces on bolt C must belocked with LOCTITE type 242. The torque setting is Nm = 90.

Collar bearings (Illustration 2)

Fit the new bearings in the succession shown 2.1, 2.2. and so on. Take care of the following beforefitting flange E:

Fit the hollow space of the flange, shown at G, with grease of good quality. Fit spline F inthe gear wheel hub so that the shaft of the flange is located safely on its place when it is presseddown.

The thread surfaces on the bolt

Hmust be locked with LOCTITE 242. Torque setting 50 Nm.

Bolts J are locked by nabs I. Torque moment is 90 3 Nm. Observe that packings K ofthe threaded pins are not damaged.

Synchronizing (Illustration 3)

Before fitting the collar bearings, ensure that the collar bearing flanges are in determined positionsrelative to each other. This is especially important for the 1st and 2nd discs on TA 337 - TA 338 -TA 338 C - TA 339, and the 7th and 8th discs on TA 338 - TA 338 C as these discs rotate in thesame direction. Synchronisation is obtained as follows:

Fit the 1st collar bearing, - turn the flange so that the marked edge M turns to the rear. Note:The flange on this collar bearing is equipped with 4 pcs. threaded holes.

Fit the 2nd collar bearing. Turn the flange so that the marked edge N turns forward in drivedirection before lowering the gear wheel into mesh. Continue with this procedure when mountingthe other collar bearings P, Q etc.

1 - 2 Transmission "gearbox - cutterbar"

Check that the opening B between the tightening ring of the shaft and the cone does not exceed1 mm. If the distance is larger knock down the flange of the cone a little.

Keep the cones clean, clen them inside 2 - 3 times per season. If the cones are unba-lanced, vibrations could occur causing damage to the cutterbar. Damage of this kindannuls the guarantee.

Always use LOCTITE 242 on the bolts of the universal joint A and on the bolts ofthe cones.

3 Balancing springs

Never try to dismantle the balancing springs. They are pre-loaded at 300 - 400 kg. Adamaged spring is replaced as a complete unit, - see the machine spare parts list.a

Winter storage

When the season is finished, preparation for winter storage should take place immediately. Startby thoroughly cleaning the machine, - then grease the machine thoroughly so that any remainingwater is pressed out of the bearings. Change the oil in cutterbar and gearbox and let the machinerotate for a few minutes.

Go over the machine for wear and other defects, - make a note of the necessary parts required forthe next season and place your order for spare parts.

Observe the safety instructions of the machine. The winter storage operations mustonly be carried out by competent persons with experience of working with agricultu-ral machinery in a secure and responsible way.

Pre-winter storage procedure:

Check all points mentioned in the MAINTENANCE part shown at page 45. Especially payattention to the cones of the cutterbar and the vertical universal joint in the left hand side.

Check the cutting discs for wear. The central cutting discs can be interchanged, so that they getthe opposite direction of rotation.

Also check the gear wheel of the cutterbar for wear by removing one collar bearing in the lefthand side (maximum load). Also check bearing back-lash. Repair of the cutterbar, - see page65.

Check rotors and Y-fingers for damaged. Replace if necessary.

Check chain transmission for wear. Also check the splined shafts of the chain wheel.

Always ensure that the machine safety equipment is not worn or damaged, e.g. drive shaftprofile tube, guards for rotating parts, tarpaulin screens.

Push the hydraulic pistons into the cylinders. Remove split-pinned bolts if necessary.

Sprinkle a thin coat of rust preventing oil all over the machine. This is especially important onall parts polished with use. Store the machine into an aerated house.
