Wenn der Fehler weiterhin besteht, wenden Sie sich zwecks Reparatur an eine autorisierte Werk- statt. 6.16 Mähwerk 6.16.1 Sicherheit Um Unfälle bei Kollisionen zu vermeiden und wichtige Mähwerkskomponenten zu schützen, ist das Gerät mit einer Leistungsbegrenzung versehen (siehe unten). • Brechbolzen zwischen Messern und Messerbal- ken. • Drehzahlbegrenzung zwischen Zahnrad und Messerwelle. • Möglichkeit für den Zahnriemen, vom Kunstst- offzahnrad zu rutschen. 6.16.2 Demontage Bei bestimmten Wartungsarbeiten ist es am ein- fachsten, wenn das Mähwerk vom Gerät abgenom- men wird. Demontieren Sie das Mähwerk wie folgt: 1. Stellen Sie die maximale Schnitthöhe ein. 2. Ziehen Sie die Spannrolle (21:H) heraus und führen Sie den Riemen (21:J) seitlich nach unt- en um die Spannrolle, um die Riemenspannung zu lockern. 3. Ziehen Sie den Riemen von der Riemenscheibe ab. 4. Heben Sie das Mähwerk an und lösen Sie die Verbindung zur Feder des Hubseilzugs (22:K). 5. Demontieren Sie auf beiden Seiten die Sicherungsschrauben (23:A). 6. Nehmen Sie das Mähwerk von den Vorderach- sen ab und bewegen Sie es nach vorn. Siehe Abb. 24.
52 DEUTSCHDE 6.16.3Montage Montieren Sie das Mähwerk wie folgt: 1. Setzen Sie das Mähwerk auf die Vorderachsen. Siehe Abb. 24. 2. Montieren Sie auf beiden Seiten die Sicherungsschrauben (23:L). 3. Stellen Sie die maximale Schnitthöhe ein. 4. Heben Sie das Mähwerk an und hängen Sie den Hubseilzug (22:K) ein. 5. Legen Sie den Riemen (21:J) um die Riemen- scheibe. 6. Ziehen Sie die Spannrolle (21:H) heraus und führen Sie sie um die Außenseite des Riemens, um diesen zu spannen. 6.16.4Messerwechsel Tragen Sie beim Wechseln von Messern bzw. Klingen Schutzhandschuhe, um Schnittverletzungen auszuschließen. Achten Sie stets darauf, dass die Messer scharf sind. So erzielen Sie optimale Mähergebnisse. Die Messer sind einmal pro Jahr zu wechseln. Kontrollieren Sie nach einer Kollision stets den Zustand der Messer bzw. Klingen. Bei einer Be- schädigung des Messersystems sind defekte Teile auszutauschen. Verwenden Sie ausschließlich Original- ersatzteile. Die Verwendung anderer Ersatzteile ist mit Risiken verbunden, auch wenn die Teile zum Gerät passen. Die Messer sind austauschbar. Um ein gleich- mäßiges Mähen zu gewährleisten, sind beide Klin- gen am selben Messerbalken stets gleichzeitig zu wechseln. Achtung! Beachten Sie bei der Montage Folgendes: • Messer und Messerbalken sind wie auf Abb. 25 zu montieren. • Die Messer können in ihren Befestigungen um 120° gedreht werden. Richten Sie die Messer so aus, dass sie um 90° zueinander versetzt sind. Siehe “6.16.5” unten. Anzugsdrehmoment: Schrauben (25:P) – 45 Nm Brechbolzen (25:Q) – 9,8 Nm Bei einer Kollision können die Brechbolzen (18:Q) abbrechen und die Klingen ausweichen. Montieren Sie in diesem Fall Original-Brech- bolzen und ziehen Sie sie wie oben beschrieben fest.6.16.5 Synchronisierung, Messer Das Mähwerk besitzt synchronisierte Messer. Wenn eines der Messer auf einen festen Gegen- stand stößt (z.B. auf einen Stein), kann sich die Synchronisierung ändern. Dadurch besteht die Ge- fahr, dass die Messer aufeinandertreffen. Korrekt synchronisierte Messer müssen um 90° zueinander versetzt sein. Siehe Abb. 26. Kontrollieren Sie nach einer Kollision stets die Synchronisierung. Wenn die Messer nicht synchronisiert sind, kann im Mähwerk einer der folgenden Fehler vorliegen: • Der Zahnriemen ist vom Zahnrad gerutscht. • Die Drehzahlbegrenzung zwischen Zahnrad und Messerwelle wurde ausgelöst. Die Pfeile auf Abb. 27 müssen bei einer intakten Einheit aufeinander weisen. Wenn die Drehzahlbegren- zung ausgelöst wurde, weisen die Pfeile nicht aufeinander. • Der Messerbalken ist falsch an der Messerwelle befestigt. Eine Montage ist in drei Stellungen möglich. Siehe 25:R. Liegt eine falsche Synchronisierung aufgrund der ersten beiden Fälle vor, wenden Sie sich zwecks Reparatur an eine autorisierte Werkstatt. 6.16.6 Reinigung Reinigen Sie die Unterseite des Mähwerks nach jedem Gebrauch. Stellen Sie die maximale Schnitthöhe ein und brin- gen Sie das Mähwerk in Transportstellung. Die Reinigung wird erleichtert, wenn das Gerät darüber hinaus mit den Vorderrädern auf eine Bret- terschicht o.s.ä. gestellt wird. Reinigen Sie die Mähwerkunterseite sorgfältig. Verwenden Sie dazu Wasser und eine Bürste. Wenn die Oberflächen gänzlich sauber und trocken sind, ist der Lack auszubessern. Tragen Sie verschleißfeste Farbe auf, die für Metall und Außenbereiche ausgelegt ist. 7 PATENT- UND MUSTER- SCHUTZ Dieses Gerät oder Teile von ihm unterliegen fol- gendem Patent- und Musterschutz: SE 97 0427 und DE M97 07 997.9, EG 000503107-0001 und -0002.

54 ENGLISHGB 3 DESCRIPTION 3.1 TransmissionThe machine is 2-wheel drive and is driven by the rear-wheels. The rear axle has a differential, which distributes the power equally to the rear wheels. So that the machine can be steered by the rear wheels they are equipped with CV joints that give a very smooth rotational transfer. So that drive works optimally over uneven ground, the front axle is flexibly suspended and can move +/-4.5° in relation to the rear axle. The cutting deck is driven via drive belts. 3.2 SteeringThe machine has rear-wheel steering. The rear- wheel steering means that the machine can easily turn around trees and other obstacles. The steering force is transferred via a cable. 3.3 Safety system The machine is equipped with an electric safety system. The safety system stops certain activities that may be hazardous in the event of incorrect op- eration. E.g. The engine cannot be started if the clutch-brake pedal is not depressed. The safety system’s function must al- ways be checked before use. The wheels have safety valves that prevent maxi- mum pressure from being exceeded in the tyres. Also see “6.5”. 3.4 Controls 3.4.1 Steering wheel (1:B) The steering wheel is used to steer the machine. Only use the steering wheel when the machine is moving. Never turn the steering wheel when the machine is stationary with the cutting deck lowered. Risk of abnormal loads and damage to the steering mechanism.3.4.2 Clutch - brake (1:D) Pedal has the following functions: • Clutch • Service brake • Parking brake The pedal has three positions: 1. Pedal released – forward drive engaged. The machine will move if a gear is engaged. Serv- ice brake not activated. 2. Pedal depressed halfway – forward drive disengaged, gear shifting can be performed. Service brake not activated. 3. Pedal fully depressed – forward drive disen- gaged. Service brake fully activated. Also see “Parking brake” below. NOTE! You must never regulate the operating speed by slipping the clutch. Use a suitable gear instead, so that the right speed is obtained. 3.4.2.1 Parking brakeThe pedal (1:D) is also the parking brake. Locking: 1. Depress the pedal (1:D) fully. 2. Turn the catch (1:E). 3. Release the pedal. Releasing : 1. Depress the pedal (1:D) fully. 2. Release the pedal. 3.4.3 Throttle/choke (1:K) A control for setting the engine speed and to choke the engine when starting from cold. If the engine runs unevenly there is a risk that the control is too far forward so that the choke is activated. This dam- ages the engine, increases fuel con- sumption and is harmful to the environment. 1. Choke – for starting a cold engine. The choke is located in the top of the groove. Do not drive in this mode when the engine is hot. 2. Full throttle – when the machine is in operation, full throttle should always be used. Full throttle is approximately 2 cm behind the choke position. 3. Idling.

Risk of burns and crushing injuries. 5.1Transportation Never drive the machine off a trailer with the engine running. Risk of the machine tipping over and causing ma- terial damage or fatal injury. If the machine is transported on a flatbed or trailer, the machine must be pushed or lifted off/on. The machine must never be driven off/on with the en- gine running as driving on slopes requires great care and the maximum permitted incline can easily be exceeded. Also see “5.5.2” and “5.5.3”. 5.2 Filling the fuel tankAlways use lead-free petrol. You must never use 2-stroke petrol mixed with oil. NOTE! Normal unleaded petrol is perishable and must not be stored longer than 30 days. Environmental petrol can be used, i.e. alkylate pet- rol. This type of petrol has a composition that is less harmful for people and nature. Petrol is highly inflammable. Always store fuel in containers that are made especially for this purpose. Only fill or top up with petrol outdoors, and never smoke when filling or top- ping up. Fill up with fuel before starting the engine. Never remove the filler cap or fill with petrol while the engine is running or still warm. Fill with petrol as follows: 1. Fold the seat up. 2. Open the fuel cap (6:R). 3. Fill with petrol carefully. 4. Reinstall the fuel cap and fold the seat down. Never completely fill the petrol tank. Leave an empty space (= at least the entire filler tube plus 1 - 2 cm at the top of the tank) to allow the petrol to expand when it warms up without overflowing. 5.3 Level check, engine oil On delivery, the crankcase is filled with SAE 10W-30 oil.Check the oil level every time before using to ensure it is correct. The machine should be standing on level ground. Wipe clean around the oil dipstick (7:S). Unscrew and pull it up. Wipe the dipstick. Slide the dipstick down completely and tighten it. Pull up the dipstick again. Read off the oil level. Top up with oil to the “FULL” mark (7:T) if the oil level is below this mark. The oil level must never exceed the “FULL” mark. This can cause the engine to overheat. Drain the oil to the correct level if the oil level exceeds the “FULL” mark. 5.4 Safety checksCheck that the results of the safety checks below are met when testing the relevant machine. The safety checks must always be car- ried out before use. If any of the results below are not met, the machine must not be used.

57 ENGLISHGB 5.5 Operating 5.5.1 Starting the engine Before starting the engine, the actions in section 5.2 - 5.4 must be carried out. 1. Open the fuel cock (10:V) which is located in front of the casing on the rear right side. 2. Check that the spark plug cable is installed on the spark plug. 3. Check to make sure that the cutting deck is dis- engaged. 4. Set the gear control to neutral (N). 5. Starting cold engine – put the throttle control in the choke position. Starting warm engine – set the throttle control to full throttle (approx. 2 cm behind the choke position). 6. Depress the clutch – brake pedal fully. 7. Turn the ignition key and start the engine. 8. Once the engine has started, move the throttle control gradually to full throttle (approx. 2 cm behind the choke position) if the choke has been used. 9. When starting from cold, do not make the ma- chine work under load immediately, but let the engine run for a few minutes first. This will al- low the oil to warm up. 5.5.2 Starting driving The machine must not be driven in any direction on slopes with a gradient greater than 10º. See fig. 11. Always operate the machine at full throttle when driving. 1. Depress the clutch – brake pedal fully. 2. Engage the desired gear. 3. Slowly release the clutch-brake pedal fully and the machine starts to move in the desired direc- tion. 4. Engage the cutting deck. 5.5.3 Driving tips Ensure that the correct amount of oil is in the en- gine. Especially when driving on slopes. See 5.3. Be careful when driving on slopes. No sudden starting or stopping when mov- ing up or down a slope. Never drive across a slope. Move from the top down, or from the bottom to the top.Reduce the speed on slopes and when making sharp turns to prevent the ma- chine from tipping over or you losing control. Do not turn the steering wheel to full lock when driving in top gear and at full throttle. The machine can easily topple over. Never drive with the engine casing open. Never drive with the deck connected in the transport position. This will damage the deck’s drive belt. 5.5.4 Stop If the machine is left unattended, re- move the ignition key. The engine may be very warm immedi- ately after it is shut off. Do not touch the silencer, cylinder or cooling fins. This can cause burn injuries. 1. Depress the clutch – brake pedal fully. 2. Set the gear control to neutral (N). 3. Disengage the cutting deck. 4. Allow the engine to idle 1 - 2 minutes. Then turn the ignition key to the stop position so that the engine stops. 5. Lock the parking brake. 6. Shut off the fuel cock. 5.6 Cleaning To reduce the risk of fire, keep the en- gine, silencer, battery and fuel tank free from grass, leaves and oil. To reduce the risk of fire, regularly check the machine for oil and/or fuel leakage. Clean the machine after use. The following in- structions apply to cleaning: • If high pressure equipment is used, do not point the washer jet directly at the engine, axle seals or electrical components. • Do not point jets of water directly at the engine. • Clean the engine with a brush and/or com- pressed air. • Clean the engine’s cooling air intake (7:U). 6 MAINTENANCE 6.1 ServicingIn order to keep the machine in good condition, as regards reliability and operational safety as well as from an environmental perspective, the mainte-
58 ENGLISHGB nance work described in this chapter must be fol- lowed according o the instructions and at the stated intervals. This work should be carried out by an authorised workshop, but can also be carried out by the user. Service, carried out by authorised workshops, guarantees a professional job with original re- placement parts. We recommend taking the machine to an author- ised workshop after each season before it is stored for the winter. 6.2 Preparation Prevent the machine from rolling by al- ways applying the parking brake. Prevent unintentional starting of the engine by removing the ignition key. All service and all maintenance must be carried out on a stationary machine with the engine switched off. 6.3 Raising Jacks must only be placed in the desig- nated area. Placing the jack in other lo- cations will damage the machine. The machine must only be raised on hard, stable and horizontal surfaces. Otherwise there is a risk of the machine dropping. The machine must never be loaded with further weight when it is raised. No- body must sit on the machine when it is raised. For certain maintenance work, the rear part of the machine must be raised slightly so that the re- quired rear wheel can be removed. Raise the ma- chine as follows: 1. Position the machine on a hard, stable and hor- izontal surface. 2. Raise the machine using a jack, see fig. 12. 6.4 WheelsFor certain maintenance work, it is necessary to re- move a rear wheel.

Contact your dealer to purchase a battery charger with constant voltage. The battery can be damaged if a standard type bat- tery charger is used. 6.11.3 Removal/Installation The battery is placed under the seat. See fig. 4. During removal/installation of the battery, the fol- lowing applies regarding connection of the cables: • During removal. First disconnect the black ca- ble from the battery’s negative terminal (-). Then disconnect the red cable from the battery’s positive terminal (-). • During installation. First connect the red cable to the battery’s positive terminal (+). Then con- nect the black cable to the battery’s negative ter- minal (-). If the cables are disconnected/connect- ed in the wrong order, there is a risk of a short-circuit and damage to the bat- tery. If the cables are interchanged, the gen- erator and the battery will be damaged. Tighten the cables securely. Loose ca- bles can cause a fire. The engine must never be driven with the battery disconnected. There is a risk of serious damage to the generator and the electrical system. 6.11.4 Cleaning If the battery terminals are coated with oxide, they should be cleaned. Clean the battery terminals with a wire brush and grease them using terminal grease. 6.12 Air filterThe pre-filter (foam filter) (19:G) must be cleaned/ replaced every 25 operating hours. The pre-filter (paper filter) (19:F) must be cleaned/ replaced every 100 operating hours. NOTE! Clean/replace the filter more often if the machine operates in dusty conditions. Remove/install the air filters as follows. 1. Clean carefully around the air filter housing (18:E). 2. Remove the air filter cover by removing releas- ing the two clamps at the rear edge of the cover. 3. Remove the filters. The pre-filter is located far in towards the engine. Make sure that no dirt gets into the carburettor. Clean the air filter housing. 4. Clean the paper filter by gently tapping it against a flat surface. If the filter is very dirty, change it. 5. Clean the pre-filter. If the filter is very dirty, change it. 6. Assemble in reverse order. Do not use compressed air or petroleum based sol- vents such as kerosene to clean the paper filter in- sert. This will damage the filter. The paper filter insert must not be oiled. 6.13 Spark plugThe spark plug(s) must be replaced after 200 hours of operation. Before disconnecting the spark plug, clean around its mounting. Spark plug : Champion RC12YC or equivalent. Electrode distance: 0.75 mm. 6.14 Engine’s cooling air intake (7:U) The engine is air-cooled. A blocked cooling sys- tem can damage the engine. Clean the engine’s cooling air intake every 50 operating hours. A more thorough clean of the cooling system is car- ried out at each basic service. 6.15 FuseIn the event of electrical faults, check/replace the fuse, 20 A. See fig. 20. If the fault persists, contact an authorised work- shop for repair. 6.16 Cutting deck 6.16.1 Safety To reduce the risk of accidental injury in the event of a collision and to protect important parts in the cutting deck, a force limiter is integrated as fol- lows. • Shear bolts between blades and blade bar. • Torque limiting between gear wheels and blade shaft. • Possibility of positive drive belt slipping on the plastic gear wheels. 6.16.2 Dismantling It is easier to carry out certain maintenance work if the cutting deck is removed from the machine. Re- move the cutting deck as follows: 1. Set the maximum cutting height.
