General Information ROAD TRAFFIC REGULATIONS

Registration

NIn addition to his driving licence, the operator must always carry the copy of the vehicle type approval registration issued by the Kraftfahrt-Bundesamt (Federal Motor Vehicle Executive), a warning triangle and, on machines over 4 t permissible total weight, at least one wheel chock on the combine.

As a self-propelled working machine with a maximum speed of less than 20 kph the combine is not subject to the normal registration regulations and is not required to bear a registration plate. The machine must, however, be clearly and indelibly marked on the left-hand side with the christian name and surname of the owner and his address.

When driving on public roads with the combine, comply with all the requirements stated under letter C in the copy of the vehicle type approval registration (§18 Section 5 StVZO) issued by the Kraftfahrt-Bundesamt (Federal Motor Vehicle Executive).

On machines with exceptional width (width over tyres), a vehicle type approval registration for individual vehicles (single expert opinion) and an special approval in accordance with §70, Section 1, clauses 1 and 2 of the StVZO must be carried instead of the General Operating Permit. Furthermore, all the requirements stated in the vehicle type approval registration for individual vehicles and in the special approval must be observed. The issue of a special approval differs from country to country.

The excess width must be marked in accordance with the regulations for the marking of road vehicles with excess width (two warning panels at the front and back, protective bar, two warning lights for yellow flashing (rotaflare) lights.

The towing of trailers in the trailer hitch when driving on public roads is not permitted.

Road traffic regulations may vary between countries. In case of discrepancies between the instructions provided by the manufacturer and the traffic regulations of the relevant countries, the traffic regulations of the countries concerned apply.

If any parts of the combine are subsequently modified whose condition is prescribed or the operation of which (after being modified) could represent a hazard to other road users, then the vehicle type approval registration shall no longer be valid and application must be made for a new vehicle type approval registration. In this case the machine must be presented to the motor vehicle safety inspection authority responsible (TÜV) in order to obtain an expert opinion certificate (§19 section 2 STVZO).

If you are in any doubt as to whether this situation applies in your case, please contact us as manufacturers.

If a transport vehicle for attachments is towed behind the combine then the cable for the lighting system must be connected and the good condition of the lighting system assured.

If the combine is equipped with a maize header or folding cutterbar, the regulations and requirements of the General Operating Permit must be observed, in particular the requirements concerning ballast weights and tyres.

8. Clothing worn by the operator must be close-fitting. Avoid wearing loose jackets, shirts or ties!

9. Handle fuel with care as it is highly flammable.

Never refuel the machine in the vicinity of naked flames or sparks. Do not smoke during refuelling!

10. Always stop the engine and remove the ignition key before refuelling. Fill the fuel tank outdoors.

Clean up any spilled fuel immediately!

The accident prevention regulations, all other generally recognised regulations on safety and occupational medicine and the road traffic regulations must be observed at all times.

11. Prevent fires by keeping the machine clean!

Fitting and retrofitting of ancillary parts which are not original CLAAS accessories as well as modifications and alterations may only be carried out with the approval of CLAAS as they can significantly impair the safety and functional reliability of the combine.

13. Before starting the engine and before switching on the threshing mechanism, always sound the horn as a warning - pay attention to children!

12. Take care when handling brake fluid and battery acid (toxic and corrosive)!

Any arbitrary modifications carried out on the combine will relieve the manufacturer of all liability for any resulting damage or injury.

186 431.1 - BA DOMINATOR 68 S

4.1.1

Safety Rules Transporting passengers, co-driver, operating personnel 1. A passenger may only be carried if a proper passenger seat is fitted.

2. The carrying of passengers is otherwise not permitted!

Operation 1. Observe the maximum permissible axle loads and total weights!

2. The operating, steering and braking behaviour of the combine are affected, e.g. by the road surface and attached implements. Therefore always adapt your speed to the slope and ground conditions. Particular care is required when working on and driving up, down or across a slope and when the grain tank is full.

Never depress the clutch and allow the combine to roll when driving down a slope!

3. The grain tank must be empty when driving on public roads and lanes!

4. Never leave the operator's platform/cab when driving!

5. Keep a safe distance away from low overhead power lines (pay attention also to the radio and CB radio aerials, if installed)!

6. When moving the combine on public roads with the front attachment raised, the master safety switch must be switched off!

7. Before starting to drive and operate the combine harvester adjust the rear view mirror(s) to give full vision of the road and of the working area behind the combine!

8. When driving on public roads and lanes with the cutterbar fitted, the finger bar and crop lifters must be covered!

Leaving the combine harvester

Front attachments (cutterbar, etc.) and other components 1. Work under raised attachments (cutterbar, etc.) only when you are sure that the attachment is safely supported!

2. Particular care must be taken when fitting front attachments (cutterbar, etc.) or hitching trailers to the combine!

3. Cutterbar, mower bar, feed auger and reel, etc. cannot be completely shielded by design measures due to their function. For this reason, an adequate safety distance must be maintained to these moving elements during operation!

4. Gatherer chains and snapping rolls of the maize picker head cannot be completely shielded by design measures due to their function. For this reason, an adequate safety distance must be maintained to these moving elements during operation also! These instructions apply analogously for all other attachments.

5. The straw chopper has safety guards surrounding dangerous rotating blades which may continue to rotate for a certain time after the drive has been switched off. For this reason, an adequate safety distance should be maintained to the straw chopper until the drive has come to a complete standstill.

6. The augers located inside the grain tank cannot be shielded completely against accidental contact due to their function. Use a rod to clear blockages and a scoop or similar vessel to take grain samples - never use your hands or feet.

7. Before entering the grain tank, be sure that the drive is disengaged and the engine has been stopped. Ensure that no other person can restart the engine.

1. When leaving the combine harvester, ensure that it will not roll away (apply handbrake, fit wheel chocks). Shut off the engine, remove the ignition key and lock the operator's cab (if equipped)! Turn off the battery isolator switch!

2. Never leave the combine unattended as long as the engine is still running!

3. Lower front attachments (cutterbar, etc.) to the ground before leaving the combine!

4.1.2

BA DOMINATOR 68 S - 186 431.1

Safety Rules Compressor-type air conditioning system 1. The air conditioning system is filled with CFC refrigerant R 134 A. CFC refrigerants must not be allowed to escape into the atmosphere! Particular care must therefore be taken when working on the compressor-type air conditioning system.

2. Maintenance and repair work may only be carried out by air conditioning system service workshops. Refrigerant must always be drawn off and disposed of for recycling.

Maintenance 1. Repair, service and cleaning work and the elimination of malfunctions should only be performed with the drive and engine switched off. Remove the ignition key!

2. Escaping fluid (fuel, hydraulic oil, etc.) under high pressure can penetrate the skin and cause serious injury. If any fluid is injected into the skin, consult a doctor immediately as otherwise serious infections may result!

3. Be careful when opening the radiator filler cap.

As long as the engine is hot, the radiator is under pressure!

4. Dispose of oil, fuel and filters in the prescribed manner!

5. Do not attempt to mount a tyre unless you have the proper equipment and experience to perform the job safely!

6. Retighten the wheel nuts at regular intervals!

7. Only have qualified workshops carry out maintenance and repair work on the hydraulic system!

Basic rule Always check the operating and road safety of the combine before starting the machine!

Sound pressure level The sound pressure level at the operator's ear in the cab with doors and windows closed is 82 dB(A).

Description and function Cutterbar

Crop

Dividers separate the standing grain from the grain which is to be cut.

Grain, chaff, short straw Grain

Grain lifters lift lodged crops and avoid cutting losses in crops with hanging heads.

The reel moves the cut crop to the intake auger. The auger flights move the material to the cutterbar centre where the feed rake delivers it to the drum for threshing. The stone trap collects solid objects brought up by the feed rake, thus preventing damage to the threshing parts.

5.2.2

Returns Straw Chaff (Fig. 2)

BA DOMINATOR 68 S - 186 431.1

Specifications Threshing mechanism Threshing is performed by drum and concave. The bulk of the grain together with the chaff and broken straw passes through the concave onto the preparation floor of the sieve pan. The impeller delivers the straw and remainder of the grain to the straw walkers.

A deflector curtain behind the impeller holds back bouncing grains and deflects the kernels down onto the front of the straw walkers.

Straw walkers The straw walkers separate the remainder of the grain from the straw. The straw is either removed out of the combine through the rear hood or undergoes further processing by special attachments (e. g. straw chopper). The kernels separated by the straw walkers are returned to the sieve pan via the under-walker return floor. Crankshafts with agitator tines intensify the loosening of the straw on the straw walkers.

Cleaning Grain mixed with chaff and broken straw is fluffed by means of the shaking action of the preparation floor and at the same time moved onto the sieves.

The wind blast of the cleaning fan blows the light particles of chaff to the rear, out of the machine. The grain falls through the upper and lower sieve into the clean grain auger trough and is lifted by the clean grain elevator into the grain tank. All parts heavier than chaff and bigger than grain travel over the upper sieve and lower sieve, drop into the returns auger and are moved to the returns elevator. The elevator carries the returns to the drum for further threshing. Swinging the grain tank unloading tube into operating position allows the grain tank to be quickly emptied into a truck or trailer alongside the combine.

Disawning When combining grain which is unusually hard to disawn or in which it is hard to separate the seeds from the heads or husks, additional disawning plates can be installed in the concave.

186 431.1 - BA DOMINATOR 68 S

5.2.3

Specifications Considerations before combining

When combining, remember: 1. Wait until the crop has fully ripened - do not combine beforehand! (Higher yield, less moisture content and easier threshing are the result.)

2. Where the heads are bent, install grain lifters close together. Where the crop is lodged, install grain lifters further apart (on every fourth to sixth cutterbar finger).

3. Where straw and grain are brittle, set the concave wider and reduce the threshing drum speed. Too much short straw impedes the cleaning process.

Cracked grain lowers the quality.

4. Where the straw is long, damp and tough, reduce the concave clearance and increase the threshing drum speed.

5. Under damp conditions and where badly lodged crops are also grown through with greenstuff, clean the concave, straw walkers and sieves regularly.

6. Remember that the vital part of the cleaning process is the blast of the fan. Prevent the forming of »mats« on the sieves and unnecessary grain losses by using enough wind, adjusting the frogmouth sieve correctly and using a flat sieve of sufficient hole size.

7. When combining crops in which it is hard to remove the awns, additional rasp bars can be fitted to the concave.

8. To get the best results from your combine run it at the right speed. Therefore, check the speed on the straw walker shaft before the harvest. The correct speed is 220-5 rpm.

9. Correct cleaning of the air cleaner as well as clean fuel and regular oil changes are essential for high performance and long life of the engine.

Prior to Operation DRIVING THE COMBINE Danger!

Before driving the combine on the road with the front attachment raised, the control lever must be locked to prevent lowering.

Before leaving the combine, lower the front attachment to the ground, stop the engine and remove the ignition key.

Make sure to shift into second gear when driving down gradients of more than 7 % slope (braking effect of the engine).

Cold weather starting aid Perkins engine 6.3544 Excess fuel from the injector nozzles flows through leakage line (L), enters the reservoir (B) and is discharged through connector (1) into the fuel return line leading to the fuel tank. This way there is always a sufficient supply of fuel in the reservoir (B).

1

Before starting the engine from cold, hold the key for about 15 seconds in position 2 (see also Fig. 3). This opens an electrically operated valve on the preheating device (V) in the intake manifold of the engine and at the same time a preheater coil is heated.

As the valve is opened, fuel from the reservoir flows past the preheater coil where it ignites and heats the intake air.

When the engine is now started, the heated air is drawn in first which eases starting.

(Fig. 1)

Starting the engine Move throttle lever (G) to the slow idle speed position (L).

Depress the clutch.

Turn the ignition key until resistance is felt and hold for approx. 15 seconds in the preheating position. Then press in the ignition key and turn further (preheating only on Perkins engines.) When the engine has started, allow the engine to run at slow idle speed for a short time.

186 431.1 - BA DOMINATOR 68 S

6.3.1

Prior to Operation Wait for the oil pressure light and buzzer to go off and then run the engine at maximum revolutions.

A = Engine »STOP« L = Slow idle speed V = Fast idle speed During combining operations, the throttle lever must be in the position (V).

(Fig. 2) Starting at low temperatures: During the cold season, allow the engine to run at slow idle speed for a few minutes after starting. Possibly use winter fuel.

Power transmission The traction drive power comes from the engine by way of the intermediate drive to the variable speed pulley on the left-hand side of the machine.

The V-belt operated speed pulleys give infinitely variable speed in all transmission gears.

A single-disc dry clutch is located between the variable speed drive and the transmission. The transmission has three forward and one reverse gear.

3

The drive is transmitted from the transmission and differential via drive shafts and final drive reduction gears to the traction wheels.

(Fig. 3)

Gear selection and clutch Depress the clutch pedal fully. Move the gear shift lever to the desired gear.

Prior to Operation After engaging the transmission, release the handbrake and then release the clutch pedal slowly.

Do not allow the clutch to slip unnecessarily and remove foot from clutch pedal (K).

(Fig. 5) For clutch adjustment procedure, please refer to group »Maintenance«.

5 For variation of the ground speed in any of the gears, move the lever in the corresponding positions of the hydraulic control unit.

Never drive in third gear in the field with a full grain tank.

Attention!

Never drive in third gear when driving on gradients of more than 7 % slope (braking effect of the engine).

Stopping the combine 1. Depress the clutch pedal.

2. Depress the foot brake pedals.

3. Shift the gear shift lever to neutral.

Danger!

Before leaving the combine, switch off the engine, remove the ignition key, apply the parking brake and, if parking the machine on sloping ground, secure the machine additionally by putting wheel chocks in front of or behind the wheels.

186 431.1 - BA DOMINATOR 68 S

6.3.3

Prior to Operation Driving characteristics Danger!

The operating, steering and braking behaviour of the combine will be affected, e.g. by the road surface and by the front attachment (cutterbar, etc.). Therefore always adapt your speed to the ground conditions.

Particular care is required when working on and driving up, down or across a slope and when the grain tank is full. Never depress the clutch and change gear when driving down a slope.

Steering The hydrostatic steering system enables easy steering of the combine with the rear wheels.

Drive carefully on public roads and when turning: The rear of the combine swings out!

The function of the steering system is retained even when the engine is switched off. However, considerably more effort is then required for steering.

Brakes Foot brake Danger!

The brake pedals must be locked together when driving on public roads and highways to ensure that the braking effect is applied equally to both drive wheels.

6

The foot brake is designed as a single-wheel brake and can be used to facilitate driving around sharp corners or when turning when the pedal lock is removed.

Use the brakes carefully on hilly ground!

(Fig. 6)

6.3.4

BA DOMINATOR 68 S - 186 431.1

Prior to Operation The foot brake should grip after the first third of the pedal travel.

(Fig. 7) Danger!

Check the braking effect and in particular the condition of the brake pads at regular intervals!

Adjustments, maintenance and repairs to the brake system may only be carried out by specialist workshops.

7

Handbrake Brake action of handbrake (H) is independent of foot brake action. The handbrake must be effective with the handle locked in the first 3 to 4 teeth in the segment.

For reasons of safe operating conditions, ensure that the ratchet still engages securely in the segment even after prolonged use of the combine.

8.1.1

Operation – Basic Machine Cutterbar reverse drive In the event of blockages in the cutterbar and feeder housing, all the cutterbar mechanisms can be reversed by pressing the button on the operator's platform. The crop is ejected to the front in order to remove blockages.

The electric motor (E) is directly powered by the battery. The small pinion on the motor drives a large gear on the cutterbar intermediate drive shaft (W).

Shaft rotation is thus reversed.

4

Operate the electric motor with the push-button only briefly, sufficient only to clear blockages, and never longer than 10 seconds.

The starter cable for the reverse drive runs via a relay and a switch on the cutterbar drive to the push-button at the front of the instrument console. This is to assure that the reverser can only be engaged when the engine is running and the cutterbar drive is shut off.

Attention!

Before engaging the reverse drive, the cutterbar must be at an absolute standstill.

Lower the reel to its deepest position. This prevents material building up at the intake auger.

When the reel is moved all the way to the rear, lift the reel slightly to prevent the reel tines from colliding with the intake auger.

Drum repairs should only be carried out by qualified personnel!

8.2.4

BA DOMINATOR 68 S - 186 431.1

Operation – Basic Machine Cleaning the threshing parts When working in green and damp crops the drum and concave, the space behind the concave and the front of the preparation floor can quickly become clogged with dirt.

The consequences are: Poor separation in the concave, overloading of the straw walkers, unbalance of the threshing drum and uneven feeding to the sieves.

8

To ensure trouble-free operation of the combine, it is essential to check these parts regularly for dirt and to clean, when necessary.

The rasp bars should be cleaned equally to prevent the drum becoming unbalanced. Large inspection holes (N) facilitate checking and cleaning, once flaps (P) have been removed.

(Fig. 8)

Threshing drum variable speed drive On-the-go variation of drum speed combined with concave adjustments which can be carried out from the platform allow quick changes of threshing operations in order to match crop conditions. Damp long-strawed crops as well as crops difficult to thresh and disawn require faster drum speeds than dry and brittle crops.

For drum speed regulation by means of the hydraulic control unit, see group »Prior to operation«.

9

Drum drive is transmitted from the impeller shaft by way of hydraulically operated speed pulley (1), wide section V-belt (2) and spring-loaded variable speed pulley (3).

The variable speed drive allows infinitely variable drum speed from 650 to 1500 rpm.

Operation – Basic Machine Threshing drum two-step variable speed drive (Chain drive) An optional chain drive kit for threshing seeds that crack easily can be installed in place of the drum variable speed drive. Three speeds can be obtained by changing sprockets (B).

An additional fourth speed can be obtained by replacing sprocket (A) on the impeller shaft.

Sprocket A - 17 teeth Sprocket B - 64 teeth = 300 rpm 10

Sprocket A - 17 teeth Sprocket B - 45 teeth = 430 rpm Sprocket A - 17 teeth Sprocket B - 35 teeth = 550 rpm Additional speed Sprocket A - 15 teeth Sprocket B - 64 teeth = 265 rpm For a speed of 550 rpm on the drum, the standard length of chain with 72 rollers is used. For 430 rpm, add a length of 6 rollers; for a speed of 300 rpm and for a speed of 265 rpm, add an additional length of 10 rollers to the chain.

Tension the double chain moderately at tensioner bolt (S) with clamping bolt (K) slackened. After tensioning, tighten clamping bolt (K) again.

(Fig. 10) Whatever drive is used, drum speed read out is provided by tachometer in the combined instrument gauge on the operator's platform.

Operation – Basic Machine Impeller Impeller (1) slows the movement of straw coming from threshing drum (2) and guides it over straw guide plate (3) onto the front of the straw walkers. Thus the full length and width of the straw walkers is used.

(Fig. 24)

24

Deflector curtain A deflector curtain (S) behind the impeller holds back any bouncing grains and deflects the kernels down onto the front of the straw walkers.

If the curtain is worn, the kernels are thrown onto the rear end of the straw walkers and cannot be separated before the straw falls to the ground.

After a long period of service, check that the curtain is in good condition and replace it if necessary.

(Fig. 25) 25 The deflector curtain can be vertically adjusted by means of chain (K) and arrester bracket (1) on the right-hand side of the machine.

Raise the curtain in heavy, long-strawed crops and where a lot of greenstuff is encountered.

It is essential to lower the curtain again in short-strawed light crops.

Operation – Basic Machine STRAW WALKERS AND CLEANING Danger!

Repair, service and cleaning work and the elimination of malfunctions should only be performed with the drive and engine switched off. – Remove the ignition key!

Straw walkers The straw walkers separate the remaining grain from the straw and convey the straw to the rear hood.

The under-walker return pockets (T) convey the grain separated by the walkers to the preparation floor.

(Fig. 1)

1 Intensive separation system Tines (Z) increase the agitation of straw on the walkers and speed up the travel of straw over the walkers, thereby greatly increasing the separating action of the straw walkers.

(Fig. 1)

Before entering the straw walker compartment stop the engine, remove the ignition key and wait for all movement to stop.

Make sure that no other person can restart the engine.

When working in damp and weedy crops, inspect the straw walkers frequently. Clean the walkers if required.

Operation – Basic Machine Warning signal If for some reason straw piles up on the straw walkers, flap (3) releases the warning signal on the operator's platform. Stop the combine immediately, clear the blockage and remedy the cause.

(Fig. 6) The same warning signal may be released by the engine overheating as the engine cooling system is connected to the same warning system. See group »ENGINE«.

6

Preparation floor The mixture of chaff/grain/broken straw from both the concave and the straw walkers pour onto the preparing floor (1). The mixture is fluffed and evenly fed to the upper sieve (3) by the shaking action of the sieve pan.

A heavily soiled preparation floor results in an uneven flow of the crop to the sieves, causing overloading of the sieves and resulting in grain losses.

Keep the preparation floor clean at all times.

7

At the end of the preparation floor, the bulk of grain falls through the wire rake (2) onto the upper sieve, while coarse and heavier particles are retained somewhat longer. Bent tines cause a build-up of material on the preparation floor.

(Fig. 7) To ease cleaning of the threshing concave and preparation floor, the stepped section (S) of the preparation floor can be removed from the rear.

Remove the upper sieve. Loosen the hooks (H) located underneath the preparation floor and pull the preparation floor sections out of the combine.

8

When reinstalling the preparing floor sections, be sure to clean the guide tracks and firmly secure the sections by means of the hooks.

Cleaning fan Wind adjustment: The cleaning fan blows all light particles out of the combine from below. Excessive »matting« of grain, chaff and broken straw on the upper sieve can be prevented by having a sufficient volume of wind. The wind blast also helps to fluff the material.

Adjusting the fan indicator:

10

When first starting up, adjust the fan variator to lowest speed. Loosen clamp (K) and adjust plastic indicator rod (P) so that the coloured ring is on the lowest number of indicator scale (S).

The indicated scale value x 100 = approx. fan speed in rpm.

The volume of the wind can be infinitely varied with operating crank (A): To increase wind = turn crank clockwise (+) To decrease wind = turn crank anti-clockwise (–) Spring (F) applies pressure to a brake to hold the crank in a stationary position.

11

As a general rule, as much wind as possible should be used, depending on crop conditions. Operate variable speed fan drive only with combine running.

(Fig. 10, 11)

186 431.1 - BA DOMINATOR 68 S

8.3.5

Operation – Basic Machine Adjusting wind direction: The windboard in the fan housing throat can be adjusted to five positions with lever (H) after the hexagon head bolt has been removed.

Normal position for grain = 2nd hole from the bottom The lever position corresponds to the position of the windboard. With lever (H) in the normal position, there should be a clearance of 68 mm between the windboard and the bottom of the fan housing.

12

For heavy crops, adjust the windboard steeper. For light crops, adjust the windboard less steeply.

Refit and tighten the hex. bolt after the adjustment has been carried out.

(Fig. 12, 13)

13

Adjusting the frogmouth sieves The frogmouth sieves can be adjusted with levers (5, 6 and 7) to suit all sizes of grain.

Lever (5) is used to adjust the upper frogmouth sieve over its full length, including the returns pass-through area (4). Lever (6) only adjusts the returns pass-through area (4). Always set the returns pass-through area (4) wider than frogmouth sieve (3).

The setting is correct if the grain is screened out after passing over three quarters of the sieving area.

14

The returns pass-through area (4) is to be adjusted for all crops to give a gap wide enough to allow unthreshed material to drop and join the tailings.

The lower frogmouth sieve can be adjusted closer or wider with adjusting lever (7) on the left-hand side of the machine.

E = closer W = wider (Fig. 14, 15)

Lower sieve Flat sieves can be used in the lower position for combining special crops instead of the lower frogmouth sieve.

Slotted hole and round hole sieves are available in different hole sizes.

Changing the lower sieve Machines with combine performance monitor: To change the lower sieve, first remove mounting bolts (1) and fold down sensor (S).

(Fig. 16)

Undo hexagon head bolts on both sides and remove chaff plate (B).

(Fig. 17)

17 Remove the split pin from adjusting linkage (V).

8.3.7

Operation – Basic Machine Sidehill levelling (3D cleaning system) The sidehill levelling system moves the upper sieve in three directions: 1. Back and forth 2. Up and down 3. Sideways »up the slope«

The upper sieve has an additional pivot arm (A) on the left-hand side. As the degree of slope changes, control unit (S) adjusts pivot arm (A) at different angles to the upper sieve by way of hydraulic cylinder (Z) and connecting rod (B). This causes a more or less strong sideways movement of the upper sieve, essentially moving the material »up the slope«.

Divisions on the sieves are no longer required.

(Fig. 19)

19 Position of machine: A = Left-hand slope B = On flat, level ground C = Right-hand slope (Fig. 20)

20

Returns Coarse particles (e.g. unthreshed material) fall from the upper sieve and from the end of lower sieve into the returns auger which moves the material to the returns elevator. The elevator carries the returns to the drum for second threshing

8.3.8

BA DOMINATOR 68 S - 186 431.1

Operation – Basic Machine Excessive returns can be caused by: 1. Improper adjustments in the threshing mechanism, concave, speed of threshing drum (excessive amounts of cracked grain).

2. Lips of frogmouth sieves set too close or too small a hole size chosen for the lower sieve.

3. Air blast from the fan too strong or too weak.

4. Ground travel speed too fast.

21

Excessive amounts of returns reduce combine throughput and cause kernel damage and grain losses.

(Fig. 21)

Checking the returns: Operate lever (H) to open inspection flap (2). Opening (O) allows the amount and mixture of the returns to be checked while combining.

(Fig. 22)

22

Combine performance monitor The electronic performance monitor allows the operator to make full use of the capacity of the combine. As the instrument on the operator's platform indicates changes in threshing losses of grain, the operator can always drive at optimum working speed as long as grain losses do not exceed the acceptable level.

Straw walkers: (up to Serial No. ...)

Grain lost over the back of the combine with the straw falls through spouts onto sensor (S).

(Fig. 23)

8.3.9

Operation – Basic Machine Straw walkers: (from Serial No. ...)

Sensors (S) are installed on the two outermost straw walkers.

Grain lost over the back of the combine with the straw falls onto the sensors (S).

(Fig. 24)

24 Sieve pan: Grain losses over the sieve pan are registered by sensor (T, Fig. 25).

The pulses produced are amplified electronically and shown by the light band in the meter.

25

The sensors extend over the full width of the machine so that the losses are registered even when the load is not evenly spread and when combining on slopes. The number of lights illuminated in the meter light bands (D) for sieve pan and (E) for straw walkers depends on the number of pulses generated by the kernels dropping onto the sensors.

Straw and chaff produce only faint pulses which are filtered out by means of the amplifier and not displayed by the meter.

(Fig. 25, 26)

8.3.10

BA DOMINATOR 68 S - 186 431.1

Operation – Basic Machine Since the various kinds of grain have their specific properties (as shape of kernels, awns, amount of leaves on the straw etc.), a different number of grains strike the sensors although actual grain losses are the same. For this reason it is essential to adjust the sensitivity of each sensor to grain type and crop conditions (damp straw, greenstuff, etc.) with switch (A) for sieve pans and switch (B) for straw walkers on the scale from 1 to 7.

(Fig. 26) While grain losses over the straw walkers generally occur when the combine is overloaded, sieve pan losses are almost always caused by faulty combine settings.

Adjusting monitor to crop type: Adjust switches (A and B) for the crop being harvested: Maize and beans Wheat and Rye Barley Oats Lighter seeds

8.3.11

Operation – Basic Machine Adjusting the sensitivity of the sensors (sensor for straw walkers from Serial No. ...)

The sensor (C) for the straw walkers is located above the sieve pan on the right-hand side of the combine.

The sensor can be set to 3 positions: Position 1 Position 2 Position 3

= = =

for light grain for medium grain for heavy grain

(Fig. 28) 28 When a straw chopper is operated, the sensitivity of the straw walker sensors should be slightly decreased.

Start operation by driving a forward speed which suits crop conditions. When after a sufficient time of operation the fourth to fifth bulb of the meters light up steadily, stop the combine. Check the field losses in the swath. a) If loss is at a acceptable level, continue operation with selected setting. b) If the straw walker losses are too high, turn switch (B) to a higher position (about one half to one full setting higher). Now adjust forward speed until the fourth or fifth bulb in the meters (1) light up again.

If the loss rate, indicated by the fourth or fifth bulb in the meters, is acceptable, the capacity of the combine is fully utilized at this forward speed.

The performance monitor should be adjusted as described to suit changing losses in the morning, when the crop is wet with dew, at noon when the crop is absolutely dry, and in the evening when the crop gradually gets damp.

If the light band in the sieve pan meter indicates excessive losses of grain over the sieve pan, check the combine setting and check in particular whether any material »mats« on the sieves. Correct the problem, if necessary.

When the right setting for the crop being harvested has been selected with switch (A) and when the cleaning units have been properly adjusted, one of the bulbs in the lower section of the meter will be on.

Operation – Basic Machine GRAIN DELIVERY Danger!

Repair, service and cleaning work and the elimination of malfunctions should only be performed with the drive and engine switched off. – Remove the ignition key!

Augers and auger troughs Clean the clean grain and returns augers when changing crops or when plugging occurs. Open the auger flaps (4) only after the engine has been switched off and all mechanisms have stopped rotating.

(Fig. 1)

Danger!

Avoid touching the sharp edges of the augers to avoid injuries!

1

Elevators Sweep elevators with rubber paddles move the material in the lower and front half of the housings upwards. To check the chain tension, open the boot flaps (L and N) of the clean grain and returns elevators.

In the event of plugging, open the auger flaps as well as the elevator boot flaps (L and N).

2

Before clearing a blockage, always stop the engine and wait until all the mechanisms have stopped rotating. Then remove the blockage that can be reached by hand. Finally allow the combine to clear all material by gradually engaging the threshing mechanism. Always ensure that the flaps and doors are properly refitted and tightly closed.

(Fig. 2)

186 431.1 - BA DOMINATOR 68 S

8.4.1

Operation – Basic Machine Grain tank Danger!

The augers located inside the grain tank cannot be shielded completely against accidental contact due to their function.

☞ Use a rod to clear blockages and a scoop or similar vessel to take grain samples never use your hands or feet.

☞ Before climbing into the grain tank, always switch off the engine and all drives.

Ensure that no other person can start the combine again.

Filling the grain tank: The grain is carried up into the tank by way of the clean grain elevator and filler auger (Z). The filler auger reaches to the middle of the tank, provides full and even filling of the tank and allows the tank to be filled to maximum capacity.

Safety screen (G) must always be in place when the combine is operated. This is essential in order to prevent accidents.

(Fig. 3) 3 Unloading the tank: The sloping grain tank bottom panels allow the grain to flow down to the horizontal cross auger (E). The grain is moved by the cross auger to the left (as arrowed) to the unloading tube auger, which then carries the grain into the transport vehicle.

Plates (B) are tapered to provide a wider feed gap to the cross auger on the Ieft-hand side than on the right-hand side. This keeps quickly flowing seeds from building up inside the unloading augers.

When combining poorly flowing seeds (e.g. grass seed or similar crops) remove one or both the plates as necessary.

(Fig. 3)

Grain losses

Losses of grain may have different reasons.

Therefore, always determine first where the losses occur.

Check combine for leakage losses. Check whether grain is lost where working parts join, especially check auger troughs, elevators etc. Extra care should be taken to check the working parts for good fitting when combining small seeds. Repair all leaks as necessary.

Losses that are caused by overripe crops or poor weather conditions must not be taken for combine losses.

Grain losses that are due to combining usually have four main causes: – Losses of grain over the cutterbar – Losses of grain caused by insufficient threshing – Losses of grain over the straw walkers – Losses of grain over the sieve pan

– Loss of grain over the cutterbar and cutting losses

1. Adjust reel tine angling to suit crop conditions.

Maintenance – Basic Machine, Cutterbar

Maintenance – Basic Machine, Cutterbar IMPORTANT MAINTENANCE INSTRUCTIONS General maintenance instructions General Danger!

Repair, service and cleaning work and the elimination of malfunctions should only be performed with the drive and engine switched off. Remove the ignition key!

Repairs to energy storage components (springs, any pressurised accumulators etc.) require expert knowledge and the correct tools and must only be carried out by specialist service shops.

Cutterbar Danger!

Before working in or on the cutterbar, switch off the threshing mechanism and stop the engine.

When working under the attached cutterbar, always be sure it is securely supported!

Correct chain tension

The tension of steel roller chains is correct when the slack side deflects about 2 % of the centre distance between shafts under thumb pressure. When new chains are fitted, the tension should be checked at shorter intervals If a chain has excessively lengthened, shorten the chain by removing one double link.

Belts

All V-belts should always be kept under proper tension. Oiled belts can be cleaned with a soapy solution; never use gasoline or similar products for belt cleaning.

When installing a new V-belt, apply liquid Teflon to the inner face of the belt guides of belt-operated clutches.

Check the tension of new belts after the first 2 to 3 working hours and adjust their tension, if necessary.

Variable speed pulleys

Whenever the variable speed pulleys have been greased, operate the pulleys to ensure even spreading of grease on sliding parts.

Remove any accumulations of dust from between the variable speed pulley halves to make sure the pulleys can be run through their full speed range.

8 Checking the refrigerant level The refrigerant level can be checked at sight glass (G) of the filter receiver-drier.

A white float ball and a blue indicator bead can be seen in the sight glass.

(Fig. 9)

9 Function of the white float ball: The refrigerant level can be monitored by means of the white float ball.

To check the refrigerant level, the air conditioning system must be switched on.

If the white float ball is at the bottom of the sight glass, this indicates that the refrigerant level is too low. Call the refrigerant system service engineer.

If the white float ball is at the top of the sight glass, the refrigerant level is OK.

Function of the blue indicator bead: Moisture in the refrigerant circuit is collected in the filter receiver-drier. When the filter receiver-drier is saturated with moisture, the blue indicator bead turns pink.

Maintenance – Basic Machine, Cutterbar WINTER STORAGE INSTRUCTIONS FOR COMBINES Proper storage of the combine after the harvest is essential in order to obtain the optimum return on the investment capital in this machine. Thorough and conscientious maintenance and cleaning and the replacement of worn or damaged parts at this point will save time and money when the combine is required for operation again.

1. Clean the exterior of all bearings of dust and grease.

Attention!

If the combine is washed (this should be avoided, if possible), all the lubrication points must be greased after washing. Then run the combine for a few minutes and operate all the variable speed pulleys.

Hollow areas such as cable leadthroughs should not be cleaned with water as the water cannot be removed from the hollow areas and can lead to the formation of rust.

2. Clean the combine thoroughly inside and out, particularly the threshing drum, concave, the space behind the drum, the preparation floor, return floors, straw walkers and above the cleaning fan.

3. Using good quality grease, lubricate all grease points of the combine, taking care not to miss any of those requiring only annual attention. Run the combine for a short period of time to distribute the grease evenly and until the grease has slightly protruded from the bearings to form a seal. With the combine still running, operate the variable speed pulleys to distribute the grease evenly between the sliding parts.

Seal off peripheries and hubs of slip clutches with paint to keep moisture out and prevent friction surfaces from rusting.

4. Open the elevator flaps and auger troughs.

Remove screens.

5. Grease all other bare metal parts such as knife bar and crop lifters.

6. Apply corrosion inhibitor to the inner flanks of the variable speed pulleys 7. Change the hydraulic and transmission oil – see maintenance charts and group »Maintenance – Engines«.

8. After cleaning, inspect the combine for worn or defective parts and have any necessary repairs carried out immediately.

9. Park the combine in a dry place protected from the weather where no commercial fertilisers are stored.

10. Lower the cutterbar to the ground or remove to relieve the load on the hydraulic system.

11. Jack up the combine to take the load off the wheels and tyres.

Maintenance – Engine ENGINE WINTER STORAGE

Returning engine to service

Meticulous care of the shut-down engine before the combine is stored for the winter is an absolute must, as damage which might otherwise result would be irreparable.

For machines in which the coolant was drained from the engine prior to winter storage, refill the cooling system.

The greatest dangers for engines in storage are:

Do this by filling the cooling system with a mixture of 50 % corrosion-inhibiting antifreeze and 50 % water.

a) the rust that forms on the precision machined running surfaces and bearings,

Mix corrosion-inhibiting antifreeze and water thoroughly before pouring it into the cooling system.

b) the acids which may be contained in poor-quality lubricants and fuels.

When the combine is delivered (from the factory) the cooling system contains a mixture of 50 % corrosion-inhibiting antifreeze and 50 % water.

The following preservative materials are required: Corrosion protection oil, depending on the engine type, and anti-corrosion additive for the cooling system of water-cooled engines (see Lubricants Chart).

Engine preservation 1. Clean exterior of engine thoroughly.

Note!

Anti-freeze solution (50 %) has to be added to the refrigerant also in warm countries where there is no danger of frost. This serves to protect the engine.

2. Preserve engine (see engine manufacturer's operating manual).

3. Attach warning sign on oil filler neck and steering wheel which reads: »CAUTION: Engine contains anti-corrosive oil«.

4. Replace coolant hoses and hoses on charge-air cooling system every 2 years.

Check coolant for frost resistance and add anti-freeze if necessary.

5. Replace all non-metallic parts on air intake system every 2 years.

Attention!

In hot countries the concentration of corrosion-inhibiting antifreeze should not exceed 50 %, as otherwise the efficiency of the coolant will be decreased.

For further information, see the engine manufacturer's operating manual.

6. Replace air-cleaner main cartridge.

7. Coolant without anti-freeze must be drained from the radiator and the engine block. The drain taps and/or drain plugs must remain open. Attach warning sign on radiator filler neck and steering wheel which reads: »CAUTION: Engine without coolant!« Attention!

The engine must not be operated without anti-freeze.

8. Fill the fuel tank completely with diesel fuel after corrosion protection of the engine.

Do not leave the machine standing out of doors, as this would cause condensation in the fuel tank.

9. Place the battery in the care of a battery service specialist or put it to some other use.
