It is vitally important that you make sure that all users have the opportunity to read and thoroughly understand these instructions. ACCIDENT PREVENTION AND SAFETY ISSUES Most accidents connected with these machines happen because someone ignores the most elementary safety rules during operation, maintenance or transport operations. It is vital that every person who comes into contact with this machine - be it the purchaser himself, a member of his family, an employee or bystander - must strictly obey the following main safety rules. Other safety instructions are to be found on the decals which are placed on various prominent parts of the machine. Only persons who are completely familiar with the machine and who have been in- structed in the dangers associated with it should be allowed to maintain or repair the machine. Ls Please observe the safety notes contained in these operating instructions and all current statutory safety and accident prevention regulations! Zi Warning and instruction decals provide essential information concerning safe operation - observe them for your own safety! 3. Please check all nuts, bolt and other fixings, load-bearing ropes, load-bea- ring connectors and all locking devices for tightness. 4. Before using the machine, operators must familiarise themselves with all parts of the equipment and the function of all controls and adjustments. Finding out during operation may be too late! 2; Before using the spreader for the first time check that the trac- tor/spreader combination is roadworthy and in a safe operating condition. 6. Before filling the spreader with fertiliser, switch off tractor engine and remove key. Ts Before adjusting, lubricating, cleaning or carrying out any other work on the machine, switch off the PTO drive, switch off hydraulic system, switch off the tractor engine and remove the key. Wait until all moving parts have come to a complete stop. 8. Keep hands feet and clothing well away from moving parts. Do not put your hands inside the hopper. It contains a rotating auger! Do not wear loose clothing! А Do not put your hands inside the fertiliser hopper. It contains a rotating auger! 9. 10. 11. 12. 15; 14. 15, 16. 17. 18. 19; 20. Keep the hopper free of any foreign matter. Before starting and operating the machine, ensure that no person is pre- sent in the danger area around the fertiliser spreader. Make sure you have a good view all round! (Watch out for children!) Only start the fertiliser spreader when all safety devices and guards have been properly fitted (filling screens, metering chamber covers, PTO guards etc..). ATTENTION !! FERTILISER IS THROWN FROM THE OUTLETS AT HIGH SPEED , AND CAN BE DANGEROUS 7 „” MAKE SURE THAT ALL PERSONS LEAVE THE SPREADING ZONE 27% BEFORE STARTING THE SPREADER. — Never leave the fertiliser spreader running unattended. It is illegal to carry passengers when transporting or using the fertiliser spreader. When checking, adjusting or repairing the machine, always ensure that the spreader cannot be started up by mistake. Before taking the fertiliser spreader onto public roads, ensure that the spreader conforms to Road Traffic regulations (check with the authorities what protective equipment, lights and warning signs are required). Do not exceed 25 km/hr (17 mph) Powered external components (e.g. hydraulic rams) can cause serious cru- shing and cutting injuries Never allow anyone to enter the space between tractor and spreader with- out first making sure that the tractor is prevented from moving - by means of parking-brake and/or wheel-chocks! Make sure that the weight of the spreader does not make the tractor unstable. In many cases it will be necessary to add suitable weights to the front of the tractor so that tractor/spreader stability, steering and braking is not affected by the weight of the fully laden spreader. Make sure that the tractor maximum axle weights and gross weight are not exceeded. The maximum payload of the AGT fertiliser spreader is 1800kg. We recommend that you arrange for your dealer to check the condition of your spreader at the end of every season. He will pay special attention to all fixing components, load bearing ropes, hydraulic equipment, metering mechanism, manifolds and deflecting plates. da o ¿e Md <P a ms misses ZU 22x 23. 24. 25. 26. 27. 20: 29. 30. 31. 32. 33. 34. In the event of a mechanical, hydraulic or electrical breakdown during ope- ration, switch off the spreader immediately. Stop tractor engine and remove the key before checking and repairing damage. Repair all defects on the PTO shaft or its guards prior to using the fertili- ser spreader. The spreader should only be set down onto its parking stand when the hopper is empty. (Check that spreader is stable and will not move when unhitched.) Never use spreader without the hopper grids fitted. Before removing grids: - switeh off hydraulic system! - switch off PTO! - switch off tractor engine! - remove key! Before transporting the spreader make sure that the boom sections have been mechanically locked in the transport position. We recommend that ear defenders are worn when operating a tractor with- out an enclosed cab, or with cab windows open. The noise level from the spreader fan is 95 to 96db(A) during spreading. Before operating hydraulic boom section controls and hydraulic level com- pensator make sure that there are no bystanders within range! Never remove fertiliser deposits from the hopper by hand. Always use sui- table tools and make sure that PTO shaft and hydraulic equipment are switehed off. Push the fertiliser residues towards the metering shafts. Watch out for traffic and bystanders when manoeuvering with booms e- xtended! Inappropriate selection and use of fertilisers can lead to serious injury and damage to humans, animals, plant-life and the environment. Therefore select the correct type of fertiliser for your task. Treat all fertiliser with care and carefully observe manufacturer's instructions. Always select an appropriate tractor speed for the terrain concerned. When travelling across hills and valleys and across sloping ground, avoid sudden turns. When manoeuvering tight turns, switch off tractor differential lock. Never change gear or drive in neutral when going downhill. Be careful, when using single-axle trailed machines, of possible instability due to shifting or offset loads. Be particularly careful when unhitching the implement and whilst it is disconnected from the tractor. Provide adequate supports. The height of the drawbar should be adjusted by a qualified service cen- tre. The AERO AGT must only be used with tractors which are designed to ac- commodate the drawbar load of this trailed implement on a hitch arrange- ment which will not make the tractor unstable. - 6 - IMPORTANT POINTS TO CHECK ON THE HYDRAULIC SYSTEM The hydraulic system operates at high pressures. When connecting the hoses to the tractor hydraulic system, make sure that the hydraulic pressure, in both the tractor and spreader circuits, has been relieved. Make sure that hydraulic connectors for the various functions are marked on both male and female fittings in such a way that incorrect connection is impossible! Wrong connection may lead to the opposite function to that in- tended. When searching for hydraulic leaks use suitable protection (safety goggles, gloves, etc.), because pressurised hydraulic fluid can penetrate skin and cause serious injury. In the event, get medical help immediately as there is a serious risk of infection! Before working on any hydraulic equipment, lower all raised components, relieve the system pressure and switch off the engine. Remove key! Prior to making any hydraulic connections, carefully clean all connectors. When unhitching the spreader, place connectors in the holders provided. Check all hydraulic hoses regularly; At least twice per year examine the surface of all hoses for mechanical defects, (eg. cuts and abrasions, crus- hed sections, kinks, tears, leaks). Replace all damaged lines immediately. Undamaged hoses should not be used longer than five years. Replacement hoses must comply with manufacturer's specifications. PROPER USE AERO AGT pneumatic fertiliser spreaders are designed to spread dry prilled or granular fertiliser, seeds and similar material. Any other use is inappropriate. Any defects arising therefrom will invalidate the manufacturers guarantee; any risk associated therewith is borne entirely by the user. "Proper use" also entails full compliance with all operating, maintenance and repair instructions issued by the manufacturer. Your pneumatic AERO AGT fertiliser spreader should only be used, maintained and repaired by persons who are familiar with the machine and who have received in- structions with regard to potential dangers. All current, appropriate, accident prevention requirements, and all other generally recognised safety, technological, work-related and road traffic legislation must be observed. Any guarantee claims against the manufacture, for damage resulting from unauthor- ised alterations to the machine will be ruled invalid. WARNING AND INFORMATION DECALS ON THE AERO AGT FERTILISER SPREADER Decals on the machine are designed and positioned to increase the safety of all persons working with the machine. Please instruct anyone who works with the machine to obey all the warning and instruction information on these decals. Replacement decals are available through your dealer.

High application rates, as used when spreading straights, Lime, P-K fertilisers etc., will inevitably increase wear and tear on the machine. Quicklime During spreading and cleaning out, do not allow the quicklime to come into | contact with water, since the resulting high temperatures could melt the MN plastic in the feed rollers. Kieserite + Potash The very rough and hard surface of Kieserite fertiliser causes high wear on injectors, plastic pipes and manifold. - 13 = 2. COMMISSIONING 2.1 HITCHING AND UNHITCHING CAUTION! Hitching-up and unhitching trailed machines to a tractor can be danger- ous. Only hitch fertiliser spreader onto the proper coupling point. Observe permis- sible total weight. When reversing towards the implement prior to hitching up, keep bystanders away from the area between tractor and fertiliser spreader. Prevent your spreader moving unintentionally by engaging the parking brakes or chocking the wheels. Do not use tractor independent brakes during transport operations. The AERO AGT connects to the tractor hitch. The height of the drawbar must be set by a competent service centre to ensure that the fertiliser spreader is as level as possible, After the spreader has been coupled up initially, connect the brake line and the lighting system, then disengage the parking brake on the spreader. The following equipment is required on the tractor to provide the hydraulic drive for the metering mechanism: 1 double acting valve and delo a i 1 free reservoir return line. Е ar.

Unhitch in reverse order. - 14 - 2.2 FITTING THE PTO SHAFT Only use PTO shafts approved by the manufacturer. The AERO AGT is equipped with a wide angle PTO shaft. This shaft is designed for specific loads and implements. It must not be replaced with any other type. When first attaching the spreader to the tractor, the length of the shaft must be matched to your tractor. If the shaft is too long, the tractor PTO drive and the spreader will be damaged when the spreader is used. Seek to provide maximum overlap on the shaft halves . When at working length the PTO shaft should only extend by half the slide overlap when shaft is fully compressed. - 1, To adjust, move tractor/spreader so that shaft is in its shortest working position, hold shaft sections next to each other and mark (see Fig. 1). 2. If necessary, shorten inner and outer shafts by the same amount on both halves. (Fig. 3). 3. Shorten inner and outer guard by the ` u same length (Fig. 2) 1 4.

Fit PTO Shaft and connect securing chains on the free end (Fig. 6). Make sure the shaft is free to move! Do not use securing chain to support PTO shaft! Fu No other alterations of PTO shaft or drive guard are allowed. 8. The shaft guards must always be pro- perly fitted to the shaft, and the tractor PTO guards must be fitted and in perfect condition! 9. Pay special attention to the overlap of the PTO shaft sections when in trans- port and working positions! 10. Before fitting/removing the drive shaft, always switch off the tractor PTO, switch off the tractor engine and re- move the key! - 15 - — da! "added ай 11. 12. 13. 14. 15. 16. Lie 18: 19, Always fit the shaft the correct way round! The end of the PTO shaft mar- ked with the tractor symbol fits onto the tractor. To prevent the PTO guard from turning, connect up the safety chains! Before switching on the PTO drive, make sure that the correct tractor PTO speed is selected to match the implement. Before switching on the PTO drive, make sure that all bystanders are stan- ding clear! Never turn on the PTO without the tractor engine running! Before starting the PTO make sure no-one is close to the rotating compo- A À Prior to cleaning, lubricating, adjusting any PTO driven implement or the PTO shaft, always switeh off PTO drive, switch off engine and remove key! When decoupling the drive-shaft from the tractor PTO, place in the holder provided! After detaching the drive-shaft, make sure you refit the cover on the tractor PTO shaft ENGAGE PTO DRIVE AT LOW TRACTOR ENGINE SPEED ONLY! - 16 - 2.3 HYDRAULIC FAN DRIVE The fan is powered by its own hydraulic system. This system consists of a three- stage pump, hydraulic motors, reservoir with filter unit and oil cooler. The pump gearbox is designed for 1000 rpm PTO speed. If the tractor is fitted with the 1 3/8" dia, 6 spline PTO only , then a suitable converter ede be fitted pur the PTO installation. p =} я The fan drive components become hot during work - danger of injury! The pump gearbox is despatched with 0.41 of SAE 140 gear oil. Check the oil level in the gearbox daily. The level is correct if the oil reaches the lower edge of the filler hole. Initially change the gearbox oil after the first 25 hours and then every 100 hours but at least once per year. Fig. 6: 1 Breather valve 2 Filler plug 3 Control screw 4 Drain plug The hydraulic system is filled with Wintershall ATF Dextron - approx. 701 The following types of oil are also suitable: Mobil ATF 220 Castrol TQF Veedol ATF F Shell ATF Dexron II BP Autron G Fina Purifimatic 33 G BP Autran DX II Texamatic 9330 Ford ATF (M2C33 F/G) Aral ATF 22 Mobil ATF 210 Valvomatic ATF Type FA Castrol TQ Dexron II Shell Donax TF Total ATE 33 Esso ATF Dexron Esso Glide Total Dexron Aral Getriebeol ATF 33 Never mix these oils with existing oil, ie. only carry out complete oil changes. - 17 - Check the reservoir oil level daily. The oil level is satisfactory as long as it reaches to approx. 1 cm below the black marker (1). Change the hydraulic oil initially after 25 hours then every 200 hours but at least once per year. Fig. 7: 1 maximum oil level The hydraulic oil filter is located in the cap of the oil reservoir. This filter is equipped with an indicator which displays the level of oil contamination. The oil must be changed when the indicator stays in the red after the hydraulic oil has reached its operating temperature. Check the contamination level daily. Change the filter element initially after the first 25 hours then every 100 hours but at least once per year. To do this remove the filter element from the filter cap. Only engage PTO shaft at low engine speeds. The fan should be warmed up for a few minutes at low PTO speed, particularly during cold weather conditions. Fig. 8: 1 Contamination indicator 2 Filter cap and filler pipe 3 Thermal switch for cooling fan 4 Breather valve 2.4 HYDRAULIC DRIVE TO METERING MECHANISM AND BOOM CONTROL The boom control and fertiliser metering functions are controlled by an electro- hydraulic valve manifold. In the event of electrical breakdown the sy- stem can be controlled manually as long as hydraulic power remains on. Fig. 9: 1 Boom section function 2 Level compensation 3 Lift mast function 4 Metering mechanism function NOTES FOR TRACTORS WITH AXIAL PISTON PUMPS (eg. John-Deere, Case, Ford) Due to the design of their hydraulic systems the oil flow rate on these tractors must be controlled on the pressure side to 35 l. On tractors without a flow rate control facility, a separate control valve must be ob- TE à tained as an add-on part from the tractor manufacturer's service Л department. Please contact your tractor dealer. Route the free return line back to the reservoir. The minimum oil flow/pressure requirement in order to obtain maximum applica- tion rates on the spreader is 35 l/min and 150 bar pressure. During boom folding operations and spreading operations, lock the valve in the "ON" position. Important: Never combine the Free Return line (FR) and Return line (R). This may affect the control function of the valve manifold. - 19 - 2.5 LIGHTING SYSTEM AERO AGT is equipped with a front and rear lighting system. The rear lights are adjustable for width on their RHS mountings. When travelling on public roads the rear lights must be adjusted to their extreme outward positions. During spreading, move the light units inwards to prevent damage to fertiliser hoses. Fig. 10: 1 Locking pin 2.6 BRAKING SYSTEM Check brake function before every journey! The braking system should be serviced regularly by a competent workshop. Adjustments and repairs on the braking system must only be carried out by a competent workshop or a recognised brake service centre! AERO AGTs are equipped with a dual circuit air braking system and a manually operated parking brake. Do not attempt to move the spreader until the air gauge in the driver's cab reads 5.0 bar Before coupling up the AERO AGT clean all couplers to prevent ingress of dirt. After coupling up check for leaks by trying the tractor brakes. Drain air receiver daily. The air receiver must be fixed” securely in its straps and show no sign of damage. The type plate must not be rusted to the container or be loose or missing. Replace when necessary. Fig. 11: 1 Drain valve — Ио” ЧЕН Regularly remove the filter element from the line filter (every 25 hours) and clean in cleaning solvent. Dry with pressurised air and replace.

PRACTICAL USE 3.1 HYDRAULIC BOOM FOLDING The following boom section functions are controlled by the control panel - Fold/extend boom sections - Boom height adjustment - Manual level compensation When extending or folding boom sections ensure that there are no bystanders in the operating area. Make sure spreader is on level ground whilst extending or folding boom secti- ons. To extend the boom sections first "raise lift mast" which will release the boom locking mechanism. Then "extend boom sections" until the springs on the reversing levers are fully stretched. Internal control valves inside the rams ensure that the boom sections extend slowly and smoothly. With "lift mast lowered" set the boom to the required working height. The working height (even for late top-dressing) is approx. 1m above crop height measured at the deflector plate on the innermost manifold. Before commencing spreading on very uneven terrain, it is advisable to set the working width to prevent the boom sections touching the ground. Prior to folding, use the manual compensation control to set boom sections par- allel to the spreader. Raise booms by raising the lift mast until it reaches the tilt-lock end-stop. rn afr Carefully move boom sections into tilt-lock AS AM en i . A SELL TT E position! Incorrect operation (folding when booms are not parallel) can lead to damage. К Ensure that the booms are located properly into the tilt-lock. В — —— Fig. 17: 1 Tilt lock 2 Locking bolt - 23 = pe 11111 1418 ei - ча LT a я! 4 pe "e E "Fold boom sections" until the inner booms are close to the hopper and the ou- ter sections are secured by the safety hook. Finally activate the mechanical boom lock by lowering the lift mast. Ensure that the booms are secured properly. 3.2 SPREADING Carry out calibration of QUANTRON 4-6 in the yard. Before commencing spreading: Switch on main switch on control panel Switch on QUANTRON 4-6 Switch on fan drive via PTO shaft Ensure that the switch on the control panel is set to "spreading off". Turn on and lock hydraulic valve. BONE During spreading check the control functions of QUANTRON 4-6 (LED display in +/-keys.) At the end of the bout switch off spreader using QUANTRON 4-6 section feed switches or by switching the control panel master switch to "spreading off”. The life expectancy of the boom sections depends to a great extent on the way you drive your machine. On rough terrain reduce forward speed, drive slowly when in turning areas and avoid the booms touching the ground. During gear changes do not allow the PTO speed to drop from 1000 rpm for more than a short time. Too low a PTO speed causes the air stream to lose its power - Risk of blockages- - 24 - 3.3 EMPTYING AND CLEANING The spreader should be cleaned daily. Unlock and remove injector support. Slide metering chamber under openings. With QUANTRON 4-6 set to MAN-mode, set central feed roller speed and empty all rol- ler groups one after the other using the boom section feed controls. When the hopper is empty, unlock and re- lease the metering unit. Fig. 20: 1 Metering units lock 2 Chain tensioner 3 Chain guard fixing Remove all deposits from the metering pan. Also remove metering pan cover and clean à a GY PVC separators. | een on Ri (au CU Fig. 21: 1 Metering pan cover 2 Nylon brushes 3 Set screws Clean with a water hose using moderate pressure, paving particular attention to injectors and manifold. Do not use a high pressure washer when cleaning electronic or hydraulic compo- nents. Always Keep manifold and deflectors clean. Dirty deflectors can lead to inaccu- rate spreading. When cleaning the spreader after spreading quick-lime, deposits must not come into contact with water since the resulting very high tempera- tures which will melt the plastic feed rollers. For drying, place metering units into the hopper. When refitting these units make sure they are replaced in their correct position (left-hand and right-hand sides). Lock injector supports after cleaning and briefly switch on PTO. The fan will remove water from injector hoses and pipes. After cleaning, treat the spreader with biodegradable corrosion protection. Lubricated machines must only be washed at locations equipped with oil separ- ators. = 29° = 3.4 MICROGRANULATES, FINE SEEDS AND REDUCED WORKING WIDTHS When spreading grass seed, slug pellets, microgranulates and similar material, which require an application rate of less than 30kg/ha, the special feed rollers must be used. The working width can be reduced by special feed rollers. Please enquire with the factory whether the reduction you require is possible. 3.5 CHANGING THE FEED ROLLERS Unlock and remove injector support. Unlock and unhook metering unit. Loosen chain tensioner, remove chain guard and drive chain. Loosen the U-section securing the feed rollers and remove feed rollers. Insert the special feed rollers and make sure that for all 6 support bearings (V2A) the welded U-sections are pointing upwards. The scraper sections must be located on the outside of the feed rollers. Secure holding sections and ensure free movement of bearings. Do not overtigh- ten. Refit drive chains and install chain cover and chain tensioner. Adjust chain tension (approx. 1 cm deflection).

GENERAL HINTS 5.1 FAULTS AND POSSIBLE CAUSES Es Injectors overflow/pipes blocked - Check for foreign matter in injectors or pipe — Reduce application rate by reducing tractor speed - Ensure PTO speed is 1000 rpm = Feed rollers are not reaching maximum speed (70 rpm) — Ensure oil flow rate of tractor is higher than 35 l/min - In cold weather let feed roller drive run for a few minutes with boom sec- tion feed controls switched off. я Uneven fertiliser distribution - Check for blocked deflectors, manifold, pipes, hoses and injectors or build-up of fertiliser deposits = Check for damaged deflectors, manifolds and holders - Ensure clearance between metering chamber and feed roller is precisely 2mm at all points — Check for correct adjustment of PVC separators in the metering chamber. = Fan does not reach maximum speed or speed fluctuates = Check that injectors support is locked properly on both sides = Ensure PTO speed 1s 1000 rpm = In cold weather let fan run for a few minutes at low PTO speed - Check oil level and oil filter = Check for oil leaks from connectors, pumps or motors = Check whether oil shows signs of foaming through air intake in the suc- tion area. - 28 - Quantron 4-6 works irregularly due to feed roller speed fluctuation Ensure gauge wheel and sensor is in perfect condition and fitted cor- rectly. Ensure sensor supplies impulses Check sensor to gauge wheel clearance is 0.9mm Feed rollers cannot be switched off with electric boom section feed con- trols Check that 12V is available on the corresponding voltage input in the di- stributor box when boom section feed control is set to off - check cable and fixing Check voltage output in the distributor box is 12V when the boom section control is switched off - change fuse Check proper function of solenoid on spring clutch Check proper action of toggle switch and leverage Check proper function of spring clutch - outer ring is easily rotated. Spray light oil between external ring and shaft. Metering shafts do not rotate after renewed start Check whether toggle switch and linkage move easily and are located pro- perly. Check spring clutch for proper function - outer ring should rotate easily. Spray light oil between outer ring and shaft. Boom sections cannot be extended/folded Check whether boom section is fully UP Check whether safety mechanism is completely unlocked Check control valves on rams for dirt deposits Lift mast will not move Check voltage on control terminals Check valve for switch function 5.2 BOOM SETTING Adjust setting if boom sections do not sit properly on the brackets when folded. | Raise boom sections completely using the lift Slowly fold booms and check whether the in- side boom sections meet the brackets too high or too low. Adjust swivel bearing on moving frame accordingly. During folding, the boom sections must fold close to the hopper. Adjust by turning the head on the hydraulic ram. For horizontal adjustment of the boom sec- tions, use the angle rail on the outer knuckle. Fig. 25 - 29 - If the boom sections do not form a straight line, adjust the end stops on the outer knuckle. Fig. 26: 1 Adjusting bolt 2 Screws on angle rail 5.3 ADJUSTMENT OF METERING MECHANISM In order to check or correct the setting of the metering mechanism, remove pan cover and cleaning brushes. y : “15a 5 nabs sal | - Check the clearance using a feeler gauge. The clearance between metering chamber and feed rollers must be 2mm. The necessary adjustments are made using the adjusting screws. Prior to adjustment, remove the me- tering chamber. Check that the clearance is the same on both sides of the roller shafts. Do not screw the set screws too tight on the support rail to ensure that the stone pro- tector remains effective; after adjustment lock the setting with the lock nuts. To protect the feed rollers, the metering chamber must be able to deflect in case fo- reign matter gets in. To check, push metering pan downwards with both hands. The internal springs must return the pan to its initial position.
